Update 27th March 2026 : Latest Youtube Upload: The BEST Sterling Engine

Update 18th March 2026: Retrol SE-02 Steam Engine

Retrol SE-02 from ENGINE DIY last week and I had an issue with some marks/stains on the boiler. Here's a quick video of what's in the box. I'll be recording this again and will post it here along with my attempts to get rid of the marks/stains on the boiler. Once that is done, I can assemble and give it it's maiden run.

Previously:

This site is new and it will soon be full of quite a volume of work and information on various electronic - related topics. I'm in the process of transferring my notes into the various Topics pages (links on the right hand side of this page). Lots of formatting and uploading of images is still outstanding. Also each Topic needs it's own index with links. How to do this? I'll have to learn.

There are numerous other topics and projects that need documenting so keep coming back to see what's been added.
