Week 56: It's alive
My circuit boards arrived from JLCPCB and they’ve really exceeded my expectations. The front panels that I intended to be temporary turned out perfectly, and as I made Kicad fooprints for all the elements, I now have the ability to make other panels in the same style very easily. I even like the bog standard vector PCB lettering for the labels.
I soldered the remaining components onto one of the Pipistrelle boards and got some test code running. It reads all the potentiometers and inputs correctly, and I made it produce a rough sine wave using a very quick and dirty bit of code. I might need to tweak some resistor values on the output, but I’m not quite sure yet.
I’m beginning to wish that I had a proper oscilloscope. Now that they’re slim and mostly affordable, unlike the hulking CRT machines of my university days, perhaps I should invest in one.
I cycled over to Tate Britain to see the Hogarth and Europe exhibition on Thursday. My favourite of all the pieces on display was probably The Enraged Musician for the number and variety of sonic irritations illustrated.
I went in the late morning, before lunch. The exhibition was bigger than I expected, and I was starving by the time I finished. I found a nice café on Lower Marsh for lunch on the way back home.
We had a well-attended meeting of Sanshinkai on Saturday, with some members I hadn’t seen in over a year. I hope this is a sign of things to come.
