My main hobby is electronics and computing. I like to fix things and make things. Over the past few years, I have become more interested in microcontrollers and embedded programming, with platforms such as: Arduino, BBC Micro:bit, ESP8266/32 and STM32.
I also enjoy repairing vintage computers - here's a Sinclair ZX Spectrum with some significant patching up:
If I think a project is useful, I'll publish details on Github (link below) and I like to make any original hardware, such as printed circuit boards, available free for non-commercial use.
Grant Searle published a design for a multi-purpose computing platform called the MultiComp at http://searle.x10host.com/Multicomp/index.html. The aim of the design was to allow a low-cost Field Programmable Gate Array (FPGA) board to be set-up to emulate one of a number of classic vintage computers. Grant published the bare schematics for his design, but did not cover any specific form of construction for a finished MultiComp. My Multicomper circuit board design holds the FPGA board and the additional components required to complete the platform ready to be setup with Grant's FPGA code:
