Isn't that something?Sure is!

@janamarie Out of curiosity are you using esp32_camera or building something from scratch? Have you had trouble with the OV2640 moving between power states?

@kicad response to this is illuminating.
It seems that they're proud to be taking money from / promoting a defense contractor.
If FFX is reciprocally proud of using KiCad and being part of an open-source organization that serves a global audience, how about they post about what they're building with it? Just to clear the air.

Attached: 1 image I went to download KiCad 9 stable and saw the big "far field exploits" badge on their donation drive since they're matching donations. Ok, so it's some infosec thing, wireless stuff maybe? I click on the badge and get this shit. You can't really stop your open source project from being used by these types, but you don't have to accept them as a sponsor and advertise them.

@ Theremin people: these are not quite ready to productize / sell yet.
However: if you have an electrical engineering / embedded systems background and I've talked to you at some point in the past three years about participating / contributing to the project, now may be a good time to get involved. -ESK

When (if) these boards work, they will feature a few original circuits:
- flexible power supply: standard 5V USB, or a barrel jack adapter or 12V USB-C/PD
- Dual, modular ESS DACs; the secondary DAC is optional, and drives an offboard, isolated balanced stereo out
- 93% efficient, class D speaker amp that can drive up to 12 watts per channel into a 4-ohm load, with a 3-9V input voltage range; based on a relatively new IC from Diodes Incorporated
- Onboard USB/Serial and USB/MIDI conversion

At long last, beginning work on new multi-board I/O assembly with option for dual modular DAC, buffered balanced output, and 12Wpc speaker output with USB Power Delivery. With many many thanks to @sidprice and @jaxter184 on the overall systems design and architecture planning back in January, as well as Raph A., and Kate W. from the NYC Resistor community.

@cgervasi He did a bunch of posting on linkedin right after trump got shot and then deleted everything

Hypothesis confirmed: you can totally program an Altera FPGA using the wildly over-specced ESP32 programmer that sells for $10 on Amazon.

pretty crazy that for $15 you can get a processor strong enough to develop pretty much any consumer product. can't imagine what the equivalent of this would have cost in 2005
