I’ve been enjoying Electroboom’s Youtube channel, and was really interested in the various Tesla coil videos. I had a look at the OneTesla DIY kits: they look great, but way too expensive for an afternoon’s fun. Plus, shipping to the UK would likely be a faff. Somehow I had the idea to check on Ebay:Continue reading “Mini Tesla Coil kit from Ebay! (playing Bohemian Rhapsody)”

Writing A Speaker Horn Music Visualiser
As soon as I decided to add the 5×5 Blinkenlights matrix to the horn, it obviously needed to be turned into a music visualiser.

However, I realised later that I could maybe just re-purpose an old Amazon Kindle ebook reader. I’ve messed with Kindles before, ages ago: I ported an Infocom interpreter and a Manga reader toContinue reading “Turning an old Amazon Kindle into a eink development platform”
Investigating RCA CED VideoDiscs
I’ve been watching a lot of the Technology Connections Youtube channel recently. I was particularly intrigued by the series on RCA CED VideoDiscs. There’s also some information available on Wikipedia. These are Vinyl discs, very similar in concept to a Vinyl (audio) disc, except these contained video rather than audio. Unlike LaserDiscs which… use lasers,Continue reading “Investigating RCA CED VideoDiscs”
