KiCad
KiCad is an EDA program, similar to Eagle, Altium and the like. I last tried it some years ago and found it to be very difficult to use, not least because of the inevitable steep learning curve that all CAD … Continue reading
Lets have another go!
Well, inspired by the announcement of the Specnext, I’ve decided to get back to work on my ZAViouR Board. It’s been a long time coming but now, I really want to get it going. I got a little disheartened when … Continue reading
ZAViouR Demo and plans
Development continues on ZAViouR Boards v1.01 and v1.02. With a simple bit of Arduino code, you can insert Z80 Hex coded machine code into the ‘Sketch’ via bin2h.exe then compile and run it. Demonstrated here with a simple routine to … Continue reading
Universal Regulator Board
I have just published my design for a Universal Regulator Board in the Non-AVR Projects section. The idea behind it was that I was using much the same power supply for the majority of my projects, a 7805 and associated … Continue reading
ESP’ecially good!
The ESP8266 ESP-01/03 Flash/Proto v1.4 boards arrived today. I set about building one up to test it and it all checks out. I used my usual SMD soldering technique of placing blobs of solder paste on each of the connections … 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
Summer Developments
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
JOTA – 2014
This year, I’ve been invited to the Scouts JOTA/JOTI event on October 18 & 19th. JOTA (Jamboree on the Air) & JOTI (Jamboree on the Internet) organises Scouts all over the world to communicate via radio and the internet. Primarily, … Continue reading
ICSP Pogo Pin Programming Adaptor
Driven by my frustration at not being able to find a reasonably cheap supply of 2x3pin shrouded header sockets, I have knocked up an adaptor to avoid using them altogether. This is not a new idea and I’ve seen a … Continue reading
Last of the line?
Having now designed and proved the minDUINO v1.6 board, I’m intending to mount one on a box with a breadboard for rapid prototyping. However, it struck me that it wouldn’t be too difficult to add either a daughter board that … Continue reading
