Construction Projects

  • Here you will find details of completed (or as completed as they are going to be) projects. All the related documentation I have for each project is here.


Work In Progress

Like all mad scientists, I’ve got more projects on the go or sitting on the “back burner” than the mind can comfortably comprehend. Some of these are waiting for inspiration, parts, funding, or just the enthusiasm to get on with them. I’ll release technical details as I go along but it goes without saying that you construct, build and ticker with any of my ideas and designs at your own risk, with the additional risk they may not actually work or get completed.


Breadboard Things

I do a lot of prototype work with breadboards and I will list designs and projects that can be built on breadboards. You will also find hints and ideas that can make using breadboards easier.


Reviews

Sometimes I stumble across a tool, component or gizmo that I think is worthy a review.


Help & Tips

In this section I will list any pearls of wisdom, datasheets, advice and information. In fact, anything that I personally don’t want to forget and that I think others may find useful.


Reference Information

Here you will find useful reference information.


Documentation Archive

Here you will find documentation, manuals, instructions and other hobby related documentation that I don’t want to lose.


Software Projects

Some of my projects are more software than hardware related and details of these will be found here.

Programming EPROMS in itself is fast, but erasing them ready for re-use is time consuming. So for this project I decided to use EEPROMS. Ebay had numerous Chinese sellers listing all types of devices from 2K […]


  • I’ve been working on building a replica of an Acorn System 1 machine for quite some time and it’s basically been working, but had a really annoying niggle that I’ve been struggling to fix. Anyway, yesterday I was browsing an online forum and decided to post details about the problem I was having. Talk about […]


  • My day job has been insanely busy the last few weeks, and to be honest the last thing I’ve felt like doing was spending time hunched over a soldering iron or more time behind a computer screen.  I work for the NHS and all this virus business is to say the least depressing, so I […]


  • I would just like to thank the people at DipTrace for allowing me to update to a version of their PCB / Schematic software that supports creations with more pins.  I’ve been using DipTrace for years and after outgrowing the basic free version, upgraded to a non-profit version that allows my creations up to 1000 […]


  • I’ve not been around much and my hobby has taken a bit of a back seat as I’ve just been so busy with other things. However things seem to have calmed down for now and I’ve got some time to switch on the soldering iron. Whilst sorting out my late brothers affects I stumbled across […]


  • So, as always I need to apologise for neglecting things on the site but I’ve just been so busy. Besides being busy at work I’ve also been busy in the workshop. One project that I’d like to share with you is my attempt to re-create an iconic British 8-bit computer; the Acorn System 1. The Wiki […]
