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.

  • Diptrace PCB & Schematic design software

    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 […]

  • OXO with TTL Logic

    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 much to do… so little time

    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 […]

  • 3D printing 19″ card rack parts

    I like 19″ card racks and have made use of them in several projects including a custom computer and an extendable bench power supply unit. The only real problem with them is cost.The basic 19″ frame is reasonable enough, but the card front panels and some of the other bits are really expensive. So, several […]

  • Buck voltage regulators

    Ebay is awash with these type of small buck regulators and I thought it would be a good idea to put one though its paces, and I’ve written a review about my findings. You can rind it in the Review section of this site.

  • Temperature monitor & alarm

    This was one of those projects that should have taken an afternoon and ended up as a reasonably large build, however it’s now complete and working rather nicely. It’s also a perfect of example how I sometimes create a piece of test equipment for use with another project I’m working on. In this case I […]
