- Prop Dev Stick Type-C edition update
- Testing my USB Type-C example boards
- Interesting Dongle Type-A to Type-C
- Wagon power mirror controller works!
- Stephen
- LND150 feedback tone stack for a Roz amp
- Similar to the Venteq this is a variable impedance filter inside a feedback loop
- Uses a modified architecture
- LND150 makes up the active element
- From ~80V to 400V it is linear and does not shift amplitude
- High voltage power supply still working great
- Macro Amp
- Looking at the component layout
- Need to get octal sockets and J-Fets for the buffers
- LND150 feedback tone stack for a Roz amp
- R.F.O.
- Know your fits and tolerances
- Great video covering tolerances and fits for mechanical design
- New engineers – selecting tolerance too tight. Most of the time this is not needed.
- Fits – Ansi standards
- Machinists handbook 30th edition $35 on Amazon.
- Pillow Flight game
- Pico-8 game
- The Kalashnikov assault rifle changed the world. Now there’s a Kalashnikov kamikaze drone.
- How will the future of hobby drones be affected by this?
- FAA Mandates External Registration Markings for Drones
- Hunting traps in most states have this requirement
- Kalashnikov also makes an Electric Vehicle?
- This reminds us of when the Media was scared that 3D printers could make “Ghost Guns”
- Know your fits and tolerances

Stephen’s…. questionable tone stack prototype using the high voltage LND150. There is 400V running through this!
Special thanks to whixr over at Tymkrs for the intro and outro!
