| Ultralowdrift preamp gives a regular multimeter 100nV resolution and a scope 10uV/div sensitivity (dc-100kHz). The PCB serves as front-panel...
| Very simple and cheap DIY controller that enables modulation of various synthesizer signals. YouTube movie shows the concept
| Oscillator sweeps from 20kHz to 20Hz controlled by sponge capacitor. Sponge material shows an extremely large dielectric constant (>1k), ena...
| Provides flexible and dynamic signal distortion as a sound effect for synthesizers and gitars. A chain of saturating amplifiers with switcha...
| This new circuit provides flexible and modulated distortion effects for synthesizers and gitars. A series chain of saturating amplifiers is...
| Increase potentiometer frequency control span with a factor of 10 or more by wiring it up differently. This approach can also be used to ext...
| Transmission up to 1 GHz over a breadboard allows testing without soldering. An example measuring selfresonance of capacitors is shown. This...
| Produces a true random signal using a thermal noise source: a resistor. The output has a predictable noise density, determined by a physics...
| A tiny circuit that removes most of the lead vocal from a popsong (instant karaoke?). Audio examples demonstrate the working of the circuit....
