The quest for the right connector for a project! The right of passage for any hardware electrical engineer starts with a connector catalog.
This is the last installment of Stephen's 'Adventures in Injection Molding'. We are going to recap the entire two year sage and close the book on it.
The Jeep Prop Fan project rides again! Well some iteration of it at least. Lets design an open source PCM (Power Control Module) for automotive apps!
Parker is an Electrical Engineer with backgrounds in Embedded System Design and Digital Signal Processing. He got his start in 2005 by hacking Nintendo consoles into portable gaming units. The following year he designed and produced an Atari 2600 video mod to allow the Atari to display a crisp, RF fuzz free picture on newer TVs. Over a thousand Atari video mods where produced by Parker from 2006 to 2011 and the mod is still made by other enthusiasts in the Atari community.
In 2006, Parker enrolled at The University of Texas at Austin as a Petroleum Engineer. After realizing electronics was his passion he switched majors in 2007 to Electrical and Computer Engineering. Following his previous background in making the Atari 2600 video mod, Parker decided to take more board layout classes and circuit design classes. Other areas of study include robotics, microcontroller theory and design, FPGA development with VHDL and Verilog, and image and signal processing with DSPs. In 2010, Parker won a Ti sponsored Launchpad programming and design contest that was held by the IEEE CS chapter at the University. Parker graduated with a BS in Electrical and Computer Engineering in the Spring of 2012.
In the Summer of 2012, Parker was hired on as an Electrical Engineer at Dynamic Perception to design and prototype new electronic products. Here, Parker learned about full product development cycles and honed his board layout skills. Seeing the difficulties in managing operations and FCC/CE compliance testing, Parker thought there had to be a better way for small electronic companies to get their product out in customer's hands.
Parker also runs the blog, longhornengineer.com, where he posts his personal projects, technical guides, and appnotes about board layout design and components.
Stephen Kraig began his electronics career by building musical oriented circuits in 2003. Stephen is an avid guitar player and, in his down time, manufactures audio electronics including guitar amplifiers, pedals, and pro audio gear. Stephen graduated with a BS in Electrical Engineering from Texas A&M University.

Hello, and welcome to the macro fab engineering podcast. We're your hosts, Parker Dolan
and Steven Craig. And this is episode 89.
So I'd like to give a shout out to Tom Anderson. He is a longtime listener, and he is one of our vocal people in our Slack channel, talks a lot helps people out in that channel. But he just came out with his own podcast called function. I think the URL is function podcast.com. So it's pretty easy to remember. And it's about art and engineering in the crossroads that you get when those mix. That's really cool. I'm
gonna check that out. Yeah,
so they got four episodes already up. They, they're, I think Episode Four is the one I was listening to. It's about an hour and a half long. So did you like it? Yeah, it's pretty good. Cool. Cool. It reminds me a lot about that episode, when we talked to
Patrick and Patrick Kelly.
Yes, yep. Yeah. Like that.
We actually just finished that project well finished is in quotes. So that's a project that's sort of going to be ongoing. But But that whole project, that's the museum science museum project. Yep.
So I had an idea about the science museum project. Oh, we should do a video log. Podcast. Right. Okay. So we go and go over there and go check it out.
Let's do that. When when they're 100%. Like,
oh, it's all working. You know, I'm saying it's already open. Like we go buy tickets. Go there.
Oh, that'd be fun. Yeah, yeah. Yeah, absolutely. Just actually tour
the whole exhibit, and show it off. And then like, the very last end will be like, because, you know, you gotta you can't you can't give the goods up early. So you have to do your part of it last, so people watch the whole
video. Yeah, yeah. Yeah, sure. The it's funny, because
you got teased at the beginning, though. Yeah.
The, the drill project that we did, has a big AC motor up at the top, and it runs on 7090 volts, something like that. I can't remember I designed it. I don't even remember, whatever, it makes a bunch of noise. And at first, we were like, Ah, this is not good. It's pretty noisy. And then we looked around at all the exhibits around it are all like, like making all these noises with it. And it's a drill and the motor sounds like a drill. So we're like, alright, this is cool. And then the museum guys are like, Yeah, that's fine. It's gonna be okay. Yeah. So cool. You're really neat.
And then on the Jeep project, which is putting cruise control factory cruise control into the jeep. I haven't got only received one part. So far one, I got the brand new connector that basically plugs into the air vacuum solenoid thing that actually pulls the cable. Okay, for the throttle body that came in that connectors for automotive stuff for that era are not cheap
anymore. How much was it? That was $45 for a single connector.
It's a four pin connector. It did come with like leads and stuff like that. So you just drop G you don't have to crimp anything you just drop them into the connector and and it's and then you know, but splice it onto your your harness wires that's what they call
it. Yeah, and that is That's right. She just starts giggling over
I'm like yeah, you bought splice together so this is the connector that I'm adding to my harness. Because it has all the other connectors I need. I just need to put extra pins in it and run new wire and then this is the connector that plugs into the actual part that does the cruise controlling. So
yeah, cool stuff. expensive parts from the 90s.
Yeah, well, the it's they're just running out of those parts now. Then when no one expected to keep you know, 99 Jeep for over a decade now.
Right and nobody manufactures that now. It's just been sitting in a warehouse.
The old new old stock parts right trying to find Mopar nos parts now is crazy. Well, you
know what, you know what's gonna happen? They're gonna open up like a warehouse somewhere in some other country and just find like, boxes and boxes and boxes. That's actually what happened
to atari. Oh, man, that was like in the 80s, late 80s or early 90s. Like they opened up a couple of warehouses that because that was when Atari was like liquidating stuff. So they sold off a whole bunch of property in California. And it just said everything was just was, yeah, they saw the property. And they just basically took if it was a full warehouse, they just didn't care. Right. So people finally started going through it and like finding how much crazy stuffs in there like 1000s and 1000s of like Atari Atari et cartridges. Oh, yeah, yeah, I heard about that. Yeah, what didn't get into the landfill, basically. Right, which is actually legit. There's a documentary on Atari on Netflix, where they actually go and find the landfill and dig up some stuff.
And they legit found stuff there. Yeah, yeah, the legend is true.
Or not as cool though. It's basically just full of ET in old cartridges. There's not there was other cards in there too. Yeah. One of my friends bought a asteroid. Asteroid. Yeah. Asteroid from the landfill. Yeah. Landfill. Bought garbage.
Legendary garbage.
Drop. Yeah. Okay, so Steven, this would be the third week in a row. We've talked about the ice bundle project.
Yeah, we'll go fast on this one. Basically, it works. And I did some calibration. So I made a bucket full of prison one, which was 12 litres of water, three kilograms of table sugar, and a whole bunch of packets of champagne yeast, it looks disgusting. It looks like mud. It looks it looks awful. It's disgusting. But it does what it needs to. And I had four of these spindles in there. And I was gathering a whole bunch of data. And they're doing what you actually
showed me a couple days ago, I think was on Tuesday of like the graph on your phone. Yep. Yeah. And you're like, showing off and like in our company chat and stuff of all the stuff that you know, the actual, like, gravity going down? Because the use is eating sugar and stuff like that.
Yeah, I can I've the actual angle of inclination. What's interesting is, is I plotted all three, or all four, sorry, devices, three of them have a really, really tight relationship of a fifth of a degree per one point of specific gravity. So they change by that much angle when gravity changes that much. And then there's another one that changes by point four, so it's twice as much. It just tilts twice as much. And I don't know why. I have no clue why. But whatever. If it's consistent, that's all that matters. It has lighter electrons in it. Yeah, yeah. Go from the exact same thing. And it just, or you,
like breathed into it and sealed it up. It was like more co2 or something.
What's cool is all the units have the dbx 18 s 20, or whatever that that that one, it's it's a one wire temperature sensor. Yeah, they all have that in there. And once all the temperature had had kind of equalized between all the devices, the the difference in temperature between four different devices was like a 10th of a degree Fahrenheit. So it's nice, like confirmation that they're all
a better that device has a 10th degree resolution.
Yeah, yeah, right. Right. Once once, one bit higher than the other, right. Mm hmm. So they, it's nice to have tight grouping of all that. Yeah. So that's that so you're gonna drink
that prison wine?
I'm gonna taste it. It's it's it's about halfway fermented. Yeah, I would write to
it all fermented, and then mix it with like Dr. Pepper.
It's just Houston tap water. Yeah, I didn't even clean the bucket that Oh, okay. I didn't need to clean just fermenting just for the alcohol. That's gonna be there's gonna be some sour stuff. Oh, it's gonna be rotten. And it's it's I have you smelled it? It smells like co2. It's what
you would expect. So actually might not be. It might not be
the Crowson. The head, the protein dump is is like a light tan color.
Oh, but you sent me the picture. It didn't look infected. No, no, no, actually, we'll probably just it'll taste bad, but it won't be in fact, so won't be. So
I use some hefty champagne yeast. So it's going to attenuate or it's going basically it's going to produce a ton of alcohol. About 18 to 20% is what this use is rated for. So it's going to be it's borderline liquor. Yeah, you know? Yeah, it's gonna be gross.
So I would I would Cold Crush it. Okay, yeah, no, put gelatin in cold crush it so you get everything. All the yeast out of it? Yep, that yeast is gonna float like crazy, right? Yeah, drop everything out. And then siphon off the top. Okay, cuz you can't distill it. Not legally, legally cannot be sold. So I would just take that and just mix it with Dr. Pepper. And a slice. Oh, I'm not sure. I bet you would not taste the difference.
And probably not. It'll be messed up. I guarantee you that. I'll give you one of the worst hangovers you've ever had.
But it will it will not taste. You won't be able to taste how bad that stuff is. Dr. Pepper? Pepper
mask? Yeah, it's certainly well, syrup and sugar. Yeah, I'll give it a shot and then we'll report on how bad it tastes. In fact, maybe I'll bring you a shot of it now might take a shot of it on the podcast that
might be like the first episode we miss because Steven just is like dead.
Somehow I'm back the next episode.
Sorry report. Stephen has died. Yeah.
He'll be back next week at our regular So yes, that that that happened.
Yeah, that happened. So what's this Daya transformation thing? Okay, same
guys that I did the science museum project. Well, not both of them, Patrick Renner, the artist. He and I are actually doing a sculpture that's going up in the contemporary art museum in Plainview, Texas on November 10. So that's the day of the opening. And the reason why we're even close the view there. quite plain, quite plain, quite plain. Actually. I've never been and I really have no clue where it is. I know it's 570 miles away from here. So I kind of I think it's Northwest Texas.
Yes. You can drive like 900 miles that direction and still be in Texas?
Yeah, Texas is just under 900 miles wide. It is monstrous. Yeah. In fact, it's from Houston. I believe it's, it's takes longer to get to the edge of Texas than it does from the edge of Texas to California, LA. Yeah, yeah. So it's a big state. Now, that
doesn't count with las traffic. Oh, well, I think you eight hours in LA traffic.
Maybe Maybe? No, sorry. Not time. But distance, distance, physical distance. Yeah. Which, you know, I sat in traffic yesterday for an hour. And after just trying to get home. And after all lit up, there was nothing. There wasn't a wreck. There wasn't anything. It was like everyone just decided, let's go slow. That is Houston traffic. There.
There was no, there's no grease stain. There's no carnage, it was just too many cars on the road.
Pretty much. Yeah. So yeah, this project, we're calling it diatomaceous transformation, which, if you kind of like diagram or dissect what that means, it's basically shifting dirt is diatomaceous is a bunch of like, dirt particles, basically. Okay, so so we're gonna have this this kind of sheet of plywood or two sheets of plywood hanging from the ceiling that all have a bunch of one and a half by one and a half inch rods of plywood, or I'd like to buy for material hanging from that. And I have devised a mechanism to which we can control each one of those rods and drop them from the ceiling at any time randomly, okay, actively. So it's a grid of these rods hanging down from the ceiling, there's 64 of them. So it's an eight by eight grid. Yeah. And I've devised a an Arduino with a with a PCB with a crap ton like shift registers, a 2595. Yeah, and 16 relays. And I can access any point on the grid, and drop randomly a one of the rods. And so our project, it's a lot more than just like dropping pieces of wood. But for the for the listeners of this podcast, they probably care more about like how the Arduino side works, then what the art actually means on that. But so yeah, no, I have, I have a device that can randomly access any point on this grid. It turns a servo motor, and it drops pins on there. So it's actually really cool. I'm happy with how the design went. So I have it all, like sketched up in Google so I can show some images on that. That'd be
really cool. Yeah, so what's supposed to represent the darkness of my soul
Plainview Texas, actually, so it's to break it down. Really quickly, we're driving on the way there, we're stopping eight times, each time we stop, we're gathering a bucket full of dirt from each location. And we're gonna paint all of the rods. And while we're painting them, we're going to sprinkle some of the dirt from each location that we stopped. And so the idea is sort of like the piece is, in a way you're traveling with us from Houston to plain view by viewing the piece and and this was supposed to drop all 64 rods across an entire month. So it'll drop to a day effectively. And so we were not deciding the piece, the Arduino is going to randomly select one and drop it. But then it drops and they create a pile on the ground of like the various dirts and distances between Houston and Plainview. And so there's there's a lot of layers that kind of get folded up into its onion. Yeah. An onion. Yeah. And it's tongue in cheek with the whole like shifting dirt. Yeah, cuz you're like,
what the pattern you got shift registers.
Oh, that's perfect. Yeah, that's perfect. It was funny because Patrick Patrick was like, What are we gonna name this pace? And I was like, we have to come up with some really like, shitty bullshit, artsy, fartsy name. And so I was like, diatomaceous transformation, because if you know what that means is just falling or shifting dirt. That's great. So yeah, we're doing that. And I've got the PCBs, and I have to actually make them. Cool,
huh? Yeah. So we got the maybe we would take a well, it's actually kind of fun to make a trip.
507 Many miles is a bit. Yeah, it's a bit. So I'm taking some days off work to do that. Yeah.
Cool. I can't wait to see the
Yeah, well, we'll certainly have some videos of that. Yeah, I think we're gonna have a professional videographer. Yeah, do some stuff
be cool to do like a time lapse of like all the whole week?
Well, we're gonna set the project up twice. So the opening night, it will drop all 64 pieces. So each, each log will drop once a once every three minutes across three hours, then we have to reset the whole thing. And it will run for an entire month after that for anyone who wants to come in. Because you know, the opening night is the night where you have everyone show up to the we're gonna want to if one dropped, it wouldn't really. So here's, yeah, here's another layer that of course, we're adding something in there, each one of the rods that hangs down the cut at different lengths, such that when it's all set up, you actually see kind of like a shape of them. And that shape is randomly determined by a handful of variables like the population of Plainview, the distance between Houston and Plainview and a handful of other things. We're going to randomize that in a Excel sheet such that the the shape of the the piece is randomly determined, and then the dropping of the pieces is randomly determined and determined, and then the end of the piece is randomly determined.
So there you go. Yeah. Okay. randomly determined, that'll be the, that'll be the title of this podcast. God was TLDR life.
Okay, so I'll mention I'll mention one thing. The hardest part of this project was creating a the code to have it shuffle an array, because I'm, I'm so piss poor at writing code that I was like, how, how do you shuffle an array? Like, it took me a while to figure that one out? I need an array that 6464 elements. And then I just wanted to shift them all around randomly without me knowing. And then I'm going to access them in row. Yeah. And then I get so
yeah, yeah. Okay, so the pic of the week. Yeah. Yeah, we're so good at that. So good transitioning. Um, this is a new chip, we actually picked it, I actually picked the chip for this for once, it's been a while. The last one was the OPA, the bigger brother of the regulator that we're using or not an op amp that we're using in the super simple power supply.
That's the OPA 541 is the original one. Yeah. And there's
the bigger brother, which is like the 71 or something like that.
We've been working on the project so long that they developed an entire another chip during
a whole nother version, that's better. Anyways, so this chip is internal inter sells new USB C buck boost chip. First, like industry that is a buck boost voltage regulator. So it's everything that you need to do the voltage for USB C power delivery in one chip.
Now, you knew that it was only a matter of time.
But it's everything in one. So you can do three, it can in your input voltages. 3.8 To 24 volts, okay, and the 3.8 is interesting, because that is one lithium cell. Ah, yeah. And then outputs five to 20, which is the entire range of voltages for the USB type C power delivery, right? I don't know what amperage, it is over that. So I don't know if it can do the 100 Watt, but
Well, if it's if it's a bit, it's a voltage regular, like all of the, it's not delivering the power directly. It's a controller, right? Possibly. So if it's a controller, then you can you could design it to deliver up to the five amp. Yeah. Because you probably connect this up to a the inductors and all the external crap. Yeah, so you can design it for whatever you want. Yeah.
And so it can do the whole range without deadzone so you can give it 3.8 volts and it will boost it to 20 or you can give it 24 And it will ramp down or you can get 7.4 volts and it can go in that entire range. That's really Yeah, that's cool. Crazy
for a single thing to do then Yeah,
so the this is this sentence I've liked a lot because it reminded me of something it leverages into cells patented are three trademarked modulation technology to deliver acoustically free noise free operation superior light load efficiency and ultra fast transient response. What does that from
the super retro turbo and calculator
deliver acoustic noise free operation,
it's not buzzy, no superior light load efficiency, which
means you don't have to load it to get 90% plus which you normally have to do for switchers, right? ultra fast transient response which is it It basically can put out a lot juice when it needs to. Yeah, yeah. What are you typing up?
I'm trying to find the turbo and calculator. thing.
Yeah, you're all right there. Well, you look on your sheet. Oh, yeah.
It's not working. We still use paper for all our notes here. I don't know why this doesn't
work. Because not blue.
Oh, yeah, it does. It's not underlined in blue. This there's one point that what is it? The Oh, the long and glorious history of the turbo and cab you later.
Are you talking about the like the the phases?
Yeah, every seventh winding is of a lotus configuration. Yeah, that's a sideshow did a joke on that sideshow, the YouTube channel. You should check that one out. It's really good because they present it like it's like it's just legit information. Yeah, it's so freakin good. We should we should link to that.
That will okay. We'll link to both of them. Yeah, um, yeah. I really want to get my hands on USB type C power delivery. I just haven't had time.
And do a full 100 Watt full 100 Watts fly. We need to do something with that.
Alright, so RFO so you got one R for this week. Okay. It is, is how to stop people from stealing your oscilloscope probes. And this was a video Keysight put out like couple of days ago. This thing is awesome. So they go through like, all like different scenarios of
what is this a joker real?
Okay, yeah. So it starts out kind of like, serious and then Amelie becomes completely silly. But, I mean, a big problem is like we even have this here. Like you go up to our probe. Rack. You You're just saying?
No, no, there's a fly. Oh, it's like right on my microphone. So it's like, oh, I don't want to get close to the microphone is a fly. What's the doing? Whatever.
Anyways, you know, like you go and try to get some gator clips off off the power for your power supply. Oh, and they're gone.
Yeah, we've had problems with it. Yeah.
So it's, you know, it's pretty relevant. And my favorite was your, your oscilloscope probes missing is like the number one cause of workplace violence and engineering firm. Oh, yeah, that's for sure. Yeah. But so they had different methods. One is like camouflaging it. And so they the guy has a scope probe down and puts camo tape. So you can't see it in quotes. Another one is you booby trapped it by putting peanut butter on it. So someone goes to the gravit to get peanut butter over their hands and you ruin the ruin the probe. One is become known as like, the person who doesn't wash his hands at work. Oh, no one will touch it.
I mean, that's not real hard in an engineering department.
You saying?
Not just it's just not hard. I mean, everyone thinks that the Engineering Department at every company doesn't wash their hands it just kind of known.
And then like another one is like, like, put out rumors or things you do with the oscilloscope probes?
Oh, yeah, that's gross. Yeah, exactly.
It's a really funny video though. But I guess the best the thing to take away this though is what would you do?
I knew that was coming. Yeah, I Yeah.
Okay. Oh, actually asked that in the video too. So,
you know, I would probably just like put them in a box of feminine care products or something like that, because there's not a single engineer that would get near that. There you go. You're done.
Yeah, I would. Short of locking them up. I would probably like just keep them on me all the time. Like you'd get like a little case, right? Like, you know, when you're in school you had like the pencil box. Uh huh. Let's go pro box. Oh, wow.
That's a really good way to get your ass kicked. Really good. But I could see you walking down the hallway with like the like the ammo belt that Chewbacca wears. Just
like Gator probes and you can have the scope probes and you can have
like, how excited you got about that? That's a really cool idea.
I think you can have like a box, like, you know has different boxes like yeah, oh, it could be like a belt that Batman work.
Yeah, shark repellent
and engineering utility belt. Where has all the probes has a multimeter it has like a box of like stock resistors stock capacitors, a a breadboard and an Arduino and Arduino could be the belt
buckle you realize like you just described like A wet dream for a lot of Kickstarter guys, that would make billions of dollars on Kickstarter. I bet you someone could take, we should have a podcast where it's just called a bunch of bad ideas. And we just we don't have a structure we just we just make bad ideas constantly. Yeah, yeah and engineering utility but a survival built. Ah. Have we have you seen? Have you seen the pause pod?
No. What's the PA?
Oh my gosh, you got to see this. It got funded? Um, I think I think it's Kickstarter. It could be Indiegogo. I was confused because I saw it on both locations. So it almost seems like these guys did two at the same time in both locations. Okay, whatever. It's the it's called the paws pod. And what it is, it's a tent that you pop up. And you can just like,
if I saw that, I saw that. And, yeah, it's a tent. It's a it's a black tent. So you pop it up, and you can have a space that no one can bother you at work.
Yeah, no, like, you can sit down and you can just like, be quiet for a minute. Or and they have like, you can upgrade it and it has like this little pop out edge. Or like this little thing. So you can lay down and have like your feet. Yeah, it's on Indiegogo. I was checking to see if it's on Kickstarter. Also. Yeah. If you want another way to get your ass kicked to work with a pause pod.
It's just like, how much of a douche? Could you be at work
that much that my dad is that is how much you can be. So it is on both? Yeah.
Any go fund in so I was looking at that. And the it's actually not a bad idea. It could completely block out sound. So you could actually use it to like, you know, get away. What pause? Yeah. Because it's just like me there's like, you know, thin nylon sounds is gonna go right through it.
Right. I mean, it's what it is. It's a it's a repurposed like, oh, yeah, yeah, yeah.
Oh, relaxation capsule. There we go for
$90,000. Yet Iris has shown us a picture from Amazon of a relaxation capsule. And what it basically is, is it looks like a Star Trek prop. And I probably probably use one of those at one time where like, a guy gets in and makes a noise round around. And then like somebody is healed, or they're going to hibernation, actually, no, I think there was an episode where like, a guy was using that. And if if he did it, like for 10 minutes every day, then he wouldn't die or something because it like rejuvenated his cells and they decided not to die or I don't know.
He just decided not to die. Yeah.
Yeah, yeah. Absolutely ridiculous. Yeah, no, the paws pod. That's, yeah, that's a good one. Yeah, just in our office manager. I was sitting in an airport with him. And he just, he just like, hey, take a look at this. That guy's gonna get his ass kicked. A picture of a dude.
Oh, that's fine. Oh, that must be when he sent it to me then to
probably Yeah, cuz it was just like, we immediately pointed
out like, the fundamental problem of it's not soundproof. And he's like, you're thinking way too much into Oh, yeah. No, way
too much way too. You know, and, and it was one of the things I looked at him. I was like, Is this all it takes? You know, is it like, literally, maybe we shouldn't get too much on those guys. But it's like, wow, like it's not that hard to make a product, I guess. Yeah. You can just repurpose something for
I don't know. Well, they just change the color. And black, you know, that looks like they make those for beaches, so you can pop something up and like change your clothes.
Oh, okay. Yeah, yeah, yeah. Or like the middle of showers or something like Yeah, yeah, it looks
just like that. Except it's black instead of blue or green? Or because they actually make the similar things to, for instance, green screens. And kids in
nurseries. Right? Yes, they do. I set up my nursery at my church every week. We have like four of those. Okay, just fine. You know what, they didn't cost 150 bucks. And the kids don't go in and take a positive I can tell you that.
The this thing though. It's also called the pause pod and supposedly for relaxing, and then you're done. And now you got to struggle to put that thing back in its enclosure. You still
ruined your pots, because just couple of people have ever tried
to like, collapse those like springy tent things.
Oh, they're terrible. Yeah, they're horrendous. Yeah, terrible. We need to come up with a different name name for it, like a, like a, like a cheat cave or something like that. You know? I don't know. Everything as
that's how that's how you get the money your product has. It's like macro. If you put a lot over the A and Fab would sound like
it probably still sound like macro fab. Lots of macro fab. Yeah. I don't know you'd have to. Whenever you see that much because it doesn't exist in our language. We just kinda like, change the way we pronounce it somehow just whatever. Like, there's a there's a there's an app called the Uber Shah, or that's the best I can pronounce it. It's stands for supersonic. That's cool. Yeah. And I just call it the Uber.
Diepen you're just gonna like,
I just open your throat a little bit, because there's the dots there. Yeah, I just take a guess. Well, hey, before we sign off, I want to give a quick thanks to Pat Hensley. Pat is a listener from day one. And he's, uh, he's been to a handful of our meetups, and he helped us with some of our projects. He helped us get the
really fancy seven segments
multimedial Demeter? Yeah, yeah. Pat gave me actually some suggestions to use for my eye spindles. And some of the gathering of the data. He called out some M 2x. Basically, I use EB dots right now, to get all of them on once as well. It should, I should check. It really should be dots. But he sent me an email saying M to x. So Thanks, Pat. I appreciate it.
So that's a different service, a client.
It's a client that gathers data. And he was basically saying it's way better than newbies in the cloud. This is my first foray into like, real IoT stuff. So I'm all like, whoo, I don't know. It's it's cloud. Is it? The pause pod? I don't know.
And he's also gonna be talking at the next meetup.
At the end of this month. That's right. Yeah, he's got a pretty cool presentation. What days that? The 25th of
October. We should all wear costumes. For the meetup. Yeah, we're supposed to have a macro fab like party or something.
So keep it secret. My team here at macro fab. We're all going to try to dress up as Bob. Bob. Bob is our logistics manager here. And he wears a blue polo and super starched pants every day to work and work and the hat. Yeah, and and and a ball cap and we're gonna try to dress up like him. Yeah. I got to get some starch. Yeah.
I was actually I'm gonna dress up as a electrolytic capacitor.
Oh, good luck sitting down.
So like a cardboard tube? That goes over your whole body? Yep. Alright, then silver pants. And then paint on the side. You know a brand name? What if I just called it gold? Fine. Like actually wrote gold fine on the side. Gold goal?
Yeah, are you going to get a big concrete cardboard tube? Or are you going to just form a circle
out? I have no idea how to do that. Yeah, yeah, I'm gonna go on Amazon and see what the largest cardboard tube I can order on Prime
Hmm. Oh, you're probably not big enough for you to fit in. Maybe not? I don't know. Yeah, probably not. But you can make your own. Yeah, it's gonna be broken in like 10 minutes.
Oh, if I made a hatch so just opened up in the front and then I can get
beer. Are you going to have the pin one stripe or the UPS or not the pin one the ground stripe. Inside? Yeah. Okay. Capacitor. What value is Parker? Oh, you should calculate what value would be being your size and
then do it like a many many ferrets. Yeah. And then, I guess you had to pick a voltage rating first, and then figure out the density of the dielectric and then scale that up. Yep. Yeah, that'd be probably the most sane method of doing it and you'd probably be close enough
yeah, so fair. A fair red cap is
advisor cookie and belt
like a 12 volt Yellen is yeah and we're no I'd say maybe a little bit bigger. Yeah. A bit one of the tall tall boys. Yeah, something like that. So just multiply that those volumes up and then yeah, get
whatever you get. Yeah, Barbie couple 1000
Couple 1000 pairs yeah shocking shocking. Yeah, and with that, yeah, that was the Mac fab engineering podcast we were your host Stephen Craig Parker them and take it easy guys
