So far, I’ve made a pretty good start on the Sound Lab:
- Entire board (sans connections to front panel and inter-board connections) is soldered. The PLUS kluges are crazy. Let me tell you that much. Pictures soon.
- I seem to be short a 33k resistor for the S&H board. Curses! It’ll have to piggyback onto my next parts order.
- Got the glass out of the dead scanner I’m using as an enclosure.
- Got a sheet of acrylic for the front panel. Need to cut it to fit, and then drill lots of holes.
- Dumb idea? Run a BlinkM on the inside with a cool pattern, leave the paper on the inside of the acrylic as a diffuser, AND HAVE THE AWESOMEST, TRIPPIEST COLOR-CHANGING SOUND LAB EVER BUILT? Maybe. I’d have to get a BlinkM, and then run a 5V rail out of the power supply. It may not have enough light output, too…
I’ve made a couple of design decisions on the cigarbox modular:
- The connection medium will actually be exposed screws – I have a large quantity of clip leads to use, and connecting the points to the circuit board can use lugs attached to the screws. Plus it’ll look really cool and dangerous.
- I want to try to only use conventionally available PCBs- nothing custom. Mostly things along the lines of the Radio Shack 276-159/Electronix Express PB-12 size factor.
- Modules: Some kind of 40106-based multi-oscillator, some logic-gate based “modulators”, a mixer somewhere at the end. Maybe a simple SVF?
- I need to find some tiny L-brackets to attach the PCBs to the cigar box. My first search (at a big-box hardware store) was fruitless.
