| A tiny circuit that removes most of the lead vocal from a popsong (instant karaoke?). Audio examples demonstrate the working of the circuit....
| This circuit detects if the temperature of an object became too high. The thyristor is mounted on the object that has to be temperature moni...
| Deze eenvoudige oscillator gebruikt slechts vier passieve componenten om een LED te laten knipperen in het donker. De schakeling werkt ongev...
| This detector circuit uses just the Arduino Nano itself, no added sensor. Blowing some air from 30cm distance can be detected. It detects v...
| Oscillator circuit using only 4 passive components to make a LED blink when it is in the dark. Note: this is a normal LED, not a blink-chip...
| This 4th order audio filter design is based on four LDRs controlled by one LED. Driving the LED you can control the cutt-off frequency from...
| Hier is een serieuze (d.w.z. geen speelgoed) en uiterst kleine muzieksynthesizer die een Arduino Mini als dubbele digitale oscillator gebrui...
| Music synthesizer with voltage controlled analog resonant filter and analog VCA. Double oscillator with wavemodulation and two loopable enve...
| This 2nd order filter uses four passive components. Frequency control with a current/voltage. Audio examples are given for synthesizer appli...
