I decided last night to go to the reembodied sound conference in February. My submission got rejected, but the festival looks really awesome and I’ve never seen Tudor’s Rainforest live before. Michel and I will probably be able to do some recording (maybe a show?) while I’m in town though, so I’m putting rain on pause, but continuing to develop the rain system – or something resembling it – to use for that.
I tried to figure out what a smaller & more portable four channel version of that might look like last night.
- One four channel battery powered amplifier unit with push tab terminals for speaker wire connections to transducers, and panel mount RCA for connection to a mixer.
- A four channel pulsar osc running on the daisy patch, which has four outs that can go direct to the amplifier unit and takes USB serial input for external control.
- Something running astrid hooked up via USB serial to the daisy patch and plugged into a zoom 4 channel audio interface with those outputs going to the daisy patch audio inputs.
The something running astrid will be my laptop at first, but I wonder if it could eventually be the pinephone instead.
I started working on the amplifier unit last night. It’s based around a dayton audio rechargable battery unit and two adafruit stereo amplifer boards.
The battery pack fits perfectly into an enclosure I got at the hardware store a while back. I got the RCA jacks mounted but ran into trouble figuring out how to mount the push tab terminal components. They need two mounting holes and then two fairly large rectangular gaps to be able to mount to the side of the enclosure. The plastic is tough and gave up on my plan to try to drill out a square. I’ll need to figure out a better way to cut into this enclosure or find a new one. I hope I can use it because it’s just barely big enough to fit everything inside and feels super sturdy when it’s all assembled.
