|NJ2X's build of a dual voltage linear power supply|
|KC2VSR built this neat Velleman Water Alarm|
|KC2VSR's build of the Velleman Water Alarm kit|
While experiementing with the completed circuit, KC2VSR found that his water alarm kit could be triggered by simply placing a finger across the sensor plates (without water). With just a touch, he then demonstrated that it doubled nicely as a Morse code practice oscillator. Fun!
