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
Radio Network
I’ve been a licenced radio amateur since 1993. My callsign is G0TDJ. Morse was always my first love in radio although I have tried many other modes. Recently, ‘Network Radio’ was drawn to my attention by an article in a … Continue reading
Spectrum Next Kickstarter Active!
After what seems a very long wait, the Spectrum Next Kickstarter campaign has started. This machine promises to be everything the retro-computing fan would need. A very well ‘speced’ machine (pardon the pun) with active development, a thriving community and … Continue reading

The ESP01/03 Flash-Prototype Boards arrived from the fabricator. Good quality boards in a reasonable time. Although not Hackvana (Sorry Mitch, I’ll be back for the next batch!). Here you see two of the boards, one populated with an ESP-01 module, … Continue reading

ProjectAVR now has a Twitter account. The truth is that it was getting a little confusing tweeting from the Project_HAB account about Project_AVR stuff. It needed to have it’s own account for organisation sake. Hopefully now, tweets from both accounts … Continue reading

It’s been busy at ProjectAVR. I’ve been squirreling away, making up minDUINO kits for the Scouts JOTA event. They are almost finished now. Just a few last minute additions on back-order. The assembly instructions are complete with included circuit diagram … Continue reading
