A technological artifact of the 50/60hz split in Japan. The timer will run at a different rate so rather than sell separate models with the timer painted differently, they just have two marks for 50 or 60hz. Beautiful.

Modular Melody Maker 2 in/2 out Quantizer Demo

i wanted to have a good quality demo of the 2in/2 out quantizer progress for the modular melody maker aka not recorded with my phone. both ADC inputs are receiving a random waveform, the waveform is quantized and output through the DAC.

for the patch, braids is receiving one of the 1v/oct signals and is going into a VCA with a triangle wave CV signal. the output of the VCA is going into IN on rings. rings is getting the other 1v/oct signal along with a gate trigger on strum.

I pulled apart an LED bulb. I can't remember the lumens but think it was 200lm. I want to use the individual LEDs with an Arduino but don't know what resistor to use with each as I'm not sure how big a punch each one packs. The resistor for all 36 tiny LEDs is in the second photo – looks like [brown black black black red] to my eyes.

Any idea how I can calculate the resistor needed for one bulb please?

A photograph of an array of tiny LED bulbs set in a circle. This is the inside of an LED lightbulb. There are 36 tiny circular bulbs on a circular breadboard being held by a hand. The board is around five centimetres in diameter.
The reverse of the circuit board from inside an LED lightbulb. There is a resistor (blue resistor with the following stripes: brown, black, black, black, red), a transistor and a couple of other modules that I don't recognise. It is being held by a hand.

Today’s “because we can”: powering antique telegraph equipment with a desk toy stirling engine. The engine produces about 400mA at 3v, which is just barely enough to actuate the voice coils on the receiver. If you listen carefully you can actually hear the engine slowing down as the load on the generator increases!
