Elektrosluch

Initially created for a research project for the Communication Systems faculty of the TU Berlin. It is a reinvention of the Elektrosluch designed by Jonáš Gruska for educational settings. I have taken the original circuit, translated it into a PCB and created a workshop around it.

For those unfamiliar with the Elektrosluch, the basic mechanism is that the LC circuit at the top of the PCB is resonating with the electromagnetic waves emitted by electronic devices. The operational amplifier amplifies the received voltage to make it listenable via wired headphones. Especially important for me was that the circuit has to be understandable at a glance, segmenting the LC circuit, the amplifier and its needed voltage divider into three distinctive sections on the PCB.

A reinvention of the MSGEQ7 chip on an PCB. The chip itself is very hard to find nowadays and they have the tendency to be faulty, so I have tried reconstructing the logic on a PCB as part of the “Projektlabor” course at the TU Berlin. It was my first PCB project, but is currently being reworked to be up to the quality of my current projects. The final result is designed to be a plug and play solution for different light set ups.
