Succeeding with Prometheus Copper Clay!

This is the process I’m now using: its had 100% success so far. This post is stitched together from various pieces; I unfortunately didn’t take pictures of the complete process for a single piece. Step 1: Roll out and mould the clay I’m working on a smooth piece of board with some acetate film stuckContinue reading “Succeeding with Prometheus Copper Clay!”

Prometheus Copper Clay Experiments

PMC clay, or Precious Metal Clay clay(sic!) is a mixture of tiny metal particles with an organic binder. It allows you to mould metal objects by hand at room temperature, then sinter them into solid objects once they have dried. Its pretty awesome stuff! The original PMC clays were silver or gold. More recently, thereContinue reading “Prometheus Copper Clay Experiments”

Bring Me The Head of Emperor Trajan!

A friend asked me to 3d print this 3D scan of Emperor Trajan. Its taken me a while to get round to it though (guiltguiltguilt!). I decided to chop the scan so just his head and shoulders were visible using Fusion 360’s mesh editing tools. I tried printing it upright originally, but it failed partwayContinue reading “Bring Me The Head of Emperor Trajan!”

Taking a Google Stadia Controller Apart and Dumping its ROM

I acquired one of these in a deal Google had running. After trying it out, I decided it wasn’t really for me, so I had an unused Stadia controller lying around…. The design is interesting; in order to reduce latency, it connects directly to Google via WiFi by itself, rather than locally to the Chromecast.Continue reading “Taking a Google Stadia Controller Apart and Dumping its ROM”

Mini Tesla Coil kit from Ebay! (playing Bohemian Rhapsody)

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. Googling for “mopidy audio visualizer” found this post, where someone did exactly that. But it wasn’t on a Pi, ran some other software, didn’t talk to a 5×5 matrix, and –Continue reading “Writing A Speaker Horn Music Visualiser”

1920s Spotify Speaker Horn

I inherited an old “Revo” speaker horn from my dad. I have a strong suspicion he acquired it from a “job lot” in an auction somewhere. He gave it the rather fetching red/gold/black paint job. Anyway, its been in my flat looking kinda cool for ages: I wanted to make it even more cool 🙂Continue reading “1920s Spotify Speaker Horn”

Turning an old Amazon Kindle into a eink development platform

I fancied getting an eink screen to use for future projects. I bought a wee one with a raspberry pi “hat” attached. 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”

Glass Frit/Powder Sifters

“Frit” is glass which has been broken up into pieces of varying size. You use different sized chunks for different purposes (eg large chunks could be used for mosaic style work, while glass powder could be used to fill in small holes and prevent bubbles). You generally need a way to separate it into differentContinue reading “Glass Frit/Powder Sifters”
