Homemade polarimetric synthetic aperture radar drone
(hforsten.com)
I have made several homebuilt radars and done some synthetic aperture imaging testing with them on the ground. I have wanted for a long time to put a radar on a drone and capture synthetic aperture images from air.

I’ve been in the keyboard community for more than two years now and my keyboard collection is starting to fill up my shelves. It’s only recently that, as an engineer, I started to think about how keyboards were really working.

Pimping my Casio with Oddly Specific Objects' alternate motherboard and firmware
(jgc.org)
Some time ago I bought a replacement motherboard for my classic Casio F-91W from Crowd Supply.
