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
You’re just Multi-faced
A lot has been going on lately so I thought I’d update the blog with some of it. Starting with a small announcement. I secured the domain www.ProjectSPECCY.com It currently re-directs here. I am unsure as yet whether I will … Continue reading
EPROM Info Table
One of the other things I am involved in is graphics. I have had this table knocking about on my hard drive for a while: It’s available from several sources and I find it very useful. Search as I might, … Continue reading

ESP8266 ESP01/03 Flash-Prototype Board
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
Park Life
I have now had a lesson in patience. My PCBs arrived from OSH Park yesterday. They are of top quality. However, I should have checked over my design a few times before submission. On the face of it, they look … Continue reading
