| This unusual circuit detects if the temperature of an object has passed a certain limit. A thyristor mounted on the object monitors the temp...

| 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...

| Are you into karaoke? Then this little circuit may be for you. It removes most of the lead vocal from a song without using active components...

| A tiny circuit that removes most of the lead vocal from a popsong (instant karaoke?). Audio examples demonstrate the working of the circuit....

| This device uses changes in temperature to detect airflow but without needing a special sensor. Instead, it uses the temperature sensor buil...

| 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...
