It’s The Final Countdown (I Hope)
The last version of the Morse Practice Oscillator has arrived. v2.04 StAR Edition (St Richards Amateur Radio club). They look really nice, and because I took the opportunity to panelise them, I got 20 of each board. They snap off … Continue reading
More Oscillations
The Morse Practice Oscillator boards finally arrived! Sometimes I dispair my orders will ever get from China to the UK without incident. I think I may use the DHL option more often. Anyway, having unpacked the new boards, I built … Continue reading
Oscillator Update
I successfully completed the Twin ‘T’ Oscillator, original by Mike Maynard – K4ICY. It’s a great circuit and sounds really good. Much better than a raspy 555 version. Mike has been kind enough to put a link to my project … Continue reading
