The weather has gone from snow to spring in the space of a week. It’s been very pleasant over the last few days. I haven’t even needed a heavy coat!
I killed an old Yamaha toy keyboard. I was trying to retrofit a MIDI input to a PSS-100 by emulating the keyboard matrix. I had mapped everything out, it was all going well, then I decided to look for a place to pull 5V off the board. My probe slipped, I accidentally bridged two contacts on the power transistor, heard a click, and now nothing works. It’ll either be easily fixable by replacing some passive components, or I’ll have managed to kill the ICs. As the power supply is now putting out 0.5 V instead of 5 V, I have some hope that it’s a power supply issue.
I’ve had a quiet week. I explored some of the streets in the area that I’d never visited before. Most of them turned out to be rather dull cul-de-sacs full of identical little 90s houses that nonetheless all cost way more than I’ll ever be able to afford. I didn’t find anything interesting, really. I ended up in one council estate that’s almost completely fenced off from the surrounding streets: every time you think you can see a way out, it’s barricaded off. I don’t really understand why that’s the case. Maybe it’s a relic of a bygone fad in town planning.
