Gregory's ServerIt's oddly liberating to design a circuit schematic in Notepad

I'm half tempted to try and squeeze a different version into this 2x8cm board as a fun challenge, but that may be for later Actually, I got this board to try out a minimal ATmega328 setup with just the crystal, resistor and the 2 capacitors Added a project page for the power supply. Just a place to put down ideas while I sketch them https://github.com/cypnk/Cabin-Life/tree/master/Power%20Supply I'm always uncomfortable when adding disclaimers to anything I.E. "Not responsible for sparks, fires, or worse, by using my poorly thought out ideas in this thing thing I wrote at 9AM on a Sunday while running low on coffee" OK I think we can call it a day This *shouldn't* immediately blow up after connecting power This was a challenge and a half without a working oscilloscope. I really can't afford a new one right now so a lot of the component values are blank (or wrong) for now (Stream of consciousness hardware hacking is a bad idea, kids. Don't try it at home) I'm still liking the Notepad schematic idea since I can freehand pretty much everything and it's not going to complain NASA's Through hole soldering guidelines might come in handy when it's time to assemble components for my power supply If I'm building it to function way off in the woods, exposed to all manner of whatnot, soldering is probably the least of my worries. But why allow the possibility for small issues to accumulate into big problems https://workmanship.nasa.gov/lib/insp/2%20books/links/sections/601%20General%20Requirements.html  @cypnk omg I love that these workmanship standards are just out there to read  @darius @cypnk as i remember, this discussion came up at sparkfun when we realized that people were *actually* sending our stuff to space on cubesats and the like. which is definitely, like, a holy shit cool moment, and then a lot like when you find out people are using it for medical devices you go wait, are you sure you want to do that, because i probably wouldn't do that |
Next challenge is making all that fit into this 3x7cm perf board
I'm not too worried about power dissipation just yet, but I'm going to try and orient all the MOSFETs to one side so their heatsinks away from the rest of the board
