In electronic design, a level translator enables communication between devices whose I/O voltages don’t match. Years ago, the I/O voltages usually matched, because most processor and logic devices ...

So far on Logic Noise, we’ve built up a bunch of sound-making voices and played around with sequencing them. The few times that we’ve combined voices together, we’ve done so using the simplest ...
