But... It does work, and you know what, we might have a new module idea on our hands :3c

Unbelievable that I have to do this to find out about sending written messages by wire.

DuckDuckGo search for 'telegram disambiguation', showing that the top result is the Wikipedia page about telegrams. But come on, I shouldn't have to do this to not get results about the messaging app.

Ohms, volts, amps, why naturally yes, but also centigrade and decibels? Is there nothing it can't test?

My Walkman was misbehaving badly, so I took it apart, cleaned all the contacts I could, reassembled it and it works a charm! So glad that the service manual had really helpful disassembly instructions. Even had PCB trace layouts and schematics. (See, this is […] [Original post on meow.social]

Had these boards for a while, but I just got round to sourcing the parts and putting them together. It's a clone of the SWTPC 6800 from 1975!

Oh no... PAiA have always been one of my biggest synth design inspirations. I owe a huge amount to their approach. RIP Scott.

"Scott Lee passed away with his family by his side on April 21st, 2026. He loved PAiA and helping others follow their passion with music. He would appreciate if we all kept the PAiA legacy moving forward. Paia.com will temporarily remain offline as his son, Nathan Lee, works to get PAiA back to operation in any way he can.

We appreciate your understanding and stay tuned for more updates to come. We look forward to being in touch soon."

Found a neat schematic for a valve amp using a pair of ECL80s, so why not give it a go ~ (There's many reasons not to give it a go, but hey, nothing ventured nothing gained...)

A wooden board with a bunch of electronic components screwed down onto it. There's two valve sockets at the top. It looks like a terrible idea.

Doing some surgery on the little Schaller amp. Two of the transistors in the tremolo channel had legs that had rusted through entirely, no wonder it wasn't working! Schaller's approach to populating the board appears to have been 'fuck the schematic, what […] [Original post on meow.social]

One fluke eBay win, and I have a new friend! Say hello to the Schaller Solo, a 25W 'universal amplifier' from the cusp of the 70s, containing eleven transistors and with a built-in tremolo. Advertised as for 'guitar, organ and other instruments'. So cute and tiny […] [Original post on meow.social]

Did perhaps the most 'traditional' piece of synth DIY I've ever undertaken. Took a whole lot of bodging, especially to get it to play nicely with Eurorack. :P

A side view, to show off all the flying leads, which have to be long enough to allow for the boards to be worked on when dismantled.
