Wow, you can put anything you want here.Here too!
Isn't that something?Sure is!

@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.

Hypothesis confirmed: you can totally program an Altera FPGA using the wildly over-specced ESP32 programmer that sells for $10 on Amazon.
Evan KahnJul 27, 2024
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

Ugh, the Altium Academy PCB design review guy is a trump supporter

FPGA people: I designed a simple breakout board that should hopefully enable the use of a dirt-cheap ESP32 programmer to flash Altera FPGAs. https://github.com/wormyrocks/espprog-to-altera

many of the world's problems would be solved if joe biden could simply be convinced to eat a whole bag of flamin' hot cheetos
