Welcome to my site, it contains mostly technical topics together with some rather eclectic subjects such as British Naval (historical) Slang words and British National Airs!

Educated in Electronic Engineering, I have specialised in the design and use of microcontrollers for over 40-years and have developed a wide ranging knowledge. I was lucky to be tutored by Professor Douglas Lewin for those who know of him or have read his books!

My personal aim is to transfer as much of my knowledge to others in the most easily understood way I can.  I particularly avoiding so-called obfuscation techniques used by many! Most of my current projects use the ESP8266 and ESP32 micro-controllers and are documented in these pages for your reference and use. Code for all projects can be found on ‘GitHub G6EJD’.

As a UK Radio Amateur, I’ve held a licence since 1981 with the call-sign of G6EJD and currently operate on all amateur bands, from HF on 80M (80 Metres wavelength or 3.5Mhz), 40M (7.0Mhz), 20M (14Mhz), 17M (18.1MHz), 15M (21MHz), 12M (24.9MHz) and occasionally 10M (28Mhz)  together with VHF on 2M (144Mhz) and can operate on UHF (440MHz() too. I operate (QSO) using nearly all transmission modes of SSB, FM, AM, CW, PSK, QPSK, HELL, FSK, MFSK, SSTV and Olivia, plus a whole lot more…I’m working towards a worldwide award known as eDX100 that requires me to contact 100 countries and so-far my country count is 85, so I have just 15 more to go
