Comments there say it didn't break, but was attached with the wrong bolts and came loose on a bump. All the same... scary! It seems like a thin steel insert (liner tube) inside the centre of an Al bar could at least fail softly - it would probably be lighter overall too.

Well, mental health is important too (reinforced by finding good people around). Perhaps even more important than physical health, in these crazy days of doom and despots.

18F14K22 internal clock PLLs to 65 MHz, software loop can generate the frequencies, Even the very cheap ones have 2 hardware comparators to detect the RF. As many LEDs / output as you have spare pins. And flexible, can add function later, standard part, good availability. Unless you live on food stamps the price would be insignificant for small series. Coding time would be less than Usenet time ;-)
