MEP EP#184: Like a Satellite Out of Hell

Podcast Notes

The MacroFab Engineering Podcast Design Contest sponsored by Mouser Electronics currently going on! The topic is Useless Machines! We have cash prizes up to $1000 for the winners. The deadline is August 10th and it is closing fast! More information can be found on here!

Stephen

  • Linear power supply design
    • Roz transformer and the appropriate taps
    • How do you estimate the dc output voltage given a transformer spec?
    • Vdc = 2*Vmax/pi
    • Power supplies for valve amplifiers Page 38
      • Very cool chart for determining DC output voltage from rectifiers with series resistance
    • http://www.hammondmfg.com/pdf/5c007.pdf
  • Drilling and tapping the trophy
      • Just got the parts day of recording

R.F.O.

  • Glasgow tongue has a taste for whisky
    • Glasgow University researchers have made a bionic tongue which can tell the difference between Glenfiddich, Laphroaig, Glen Marnoch and between different vintages of each brand sampled at the ages 12, 15 and 18.
    • Sub-microscopic slices of the two metals, arranged in a checkerboard pattern, act as the tongue’s tastebuds despite being 500x smaller than the tastebuds on a human tongue.
    • The researchers poured samples of whisky over the bionic tastebuds and measured how they absorb light while submerged.
  • So, you want to build a CubeSat? 
  •  How to Master PCB Repairs and Why You Should
    • Hardest thing about repairing circuit boards is knowing what the part was before it let the smoke out!
