When the Raspberry Pi became available for pre-order in 2012 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 when I had little work on 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 it went on from there.

My Projects

8 Pad Electronic Drum Kit *New*

Synchronising all these Sequencer/Drum Machines!

Drum Machine using sampled sounds

Thermometer with switched 5V outputs

TDM Emulator

8 Bit TDM System

Quiz Control Panel *UPDATE 2* for six contestants *New*

8/16 Input Event Logger

Sequencer for Maplin 3800 Synthesiser

Drum Trigger for E&MM Syntom/Synbal

Other uses I have put the Pi to over the years:

  • Media Centre, 3B+ running LibreElec.
  • NAS Drive(s), First I shared a drive using Raspbian, and then with Open Media Vault (OMV).
  • SETI@Home using five 3B's, four odroid C1+ and one Odroid C2, a total of 40 processors & Einstien@Home with three Pi 2B's, 12 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 with 3B+.
  • and a Desktop, 3B, 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 too 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. I have since changed the 160Gb HD to a 240GB SSD which boots straight from power on.
Since the launch of the Raspberry Pi in 2012 there has been many different models introduced and so I think a few now fall in to the catagory of bygonebytes such as the Model A & B versions 1 & 2. Many peripherals (HATS) have gone the same way, paricularly the 24 pin GPIO header variety. I bought a couple that I no longer use, shown below. Although the early Pi's may be out of fashon they are still supported and work very well.

Raspberry Pi B v1 and Raspberry Pi B v2 both now retired.
