The Floppotron 3.0 (2022)
After a long time it’s time for a big upgrade of my computer hardware orchestra. Here it is! The bigger and better Floppotron 3.0.
At the moment, it works in the same way as in the previous Floppotron – the controller moves the scanner head assembly using stepper motor with varying speed and alternating direction to avoid bumping against the chassis. That turned out to be a good decision, because there is no high voltage cables outside the rack, switching mode supplies can become noisy under load (especially when there are 16 modules) and the biggest advantage – case was built without putting much effort using off-the-shelf parts. I also spend some time to add the fine details, like slides (portamento) or vibratos to mimic the quirks in vocal or guitar parts of original songs – these has to be recreated by ear.
