I'm learning FPGAs, using the $25 Tang NANO 9K that I bought on Amazon Prime[1]. I just figured out how to use the PLL to generate clocks of arbitrary frequency, rather than the stock 27 Mhz.
I'm interested in using this board as the core of a SDR transceiver for the HF Amateur radio bands. Driving all the phases for a Tayloe polyphase mixer[4] should be trivial. The real question is, how high of a frequency can I get? ;-) Can I do 2 Meter SSB with it? I think I'll be able to do an NCO up to about 400 Mhz.
The reason I bought it in the first place is that I intend to design a BitGrid[2,3] chip, should there ever be another Google Shuttle, and this is my get to know Verilog project. I may break down and spend actual money on TinyTapeout[5] at some point in the future if Google gives up on the shuttles.

I help an older friend continue to repair electronics. He's been fixing things since the 1950s, we've tackled everything from a jammed Scotch Thermal Laminator[6] machine through to Cesium Beam Atomic Clocks[7] with "dead" tubes. (Fun fact, usually you can use a high voltage power supply and time to power the ion pump and recover the tubes)
