When the Raspberry Pi became available for pre-order I couldn't resist putting my name on the waiting list. When it arrived I unpacked it and installed the operating system then I ran out of enthusiasm, I didn't know what to do with it! So it lay around for a few years, then in a quiet, contemplative moment I thought that I should get to know the Python programming language. I started with a piece of test kit useful for testing computer systems for work (TDM and TD Emulators) then I went on from there.

My Projects

Thermometer with switched 5V outputs *NEW*

TDM Emulator

8 Bit TDM System

Quiz Control Panel *UPDATED*

8/16 Input Event Logger

Sequencer for Maplin 3800 Synthesiser

Drum Trigger for E&MM Syntom/Synbal

Other uses I put the Pi to:

  • Media Centre, LibreElec.
  • NAS Drive(s), First I shared a drive using Raspbian, and now with Open Media Vault (OMV).
  • SETI & Einstien@Home, comprised of three Pi 2B's, two B+'s, two 3B's, one Pi Zero, one pi Zero W and four Odroid C1+ - effectively 40 processors.
  • Note: The Pi 3B's overheat and crash when running SETI so I bought Flirc cases to act as a heatsink - this worked fairly well but I had to replace the supplied heat pad with a lump of aluminium and heatsink compound to improve the heat transfer. Works a treat now!..until the hot summer days, hence the thermometer project.

  • Pi-Top laptop
  • and a Desk Top which I have updated so it boots from a USB 160GB HD. This had it own set of issues, following the instructions on the web site it would not boot from the Hard Drive but worked without problem from a USB memory stick. I found that the power/startup time of the HD was to long so the simple solution was to power the drive before the Pi and hey presto it works a treat! The Hard Drive was an old one I had recovered from a laptop upgrade some years ago and put in a USB caddy, formated it exFAT and copied the Raspbian image to it with Etcher.
