Electronics Study from Basic to Advanced
This is a simple two transistor AM radio using regenerative feedback to enhance the received radio frequency signal. The variable capacitor (VC1) in parallel with coil (L1) act as a tunable resonant circuit. This “tank” circuit can be tuned to select the desired AM frequency converting it from an electromagnetic wave to an oscillating electric […]
Continue ReadingThe Concealment Solenoid Controller uses a Darlington Pair to drive the solenoid latch. The circuit works for everything from door latches to tiny compartment latches. Activation can vary depending on the application. Just a few types of activation devices include: Pin Switches, magnetic reed switches, limit switches, push button switches, or toggle switches. Other possibilities […]
Continue ReadingThis still design dates back to the 70’s. The plan was to let farmers process their own corn into pure alcohol. The heat was to be supplied using hay bales. I helped put one of these stills together but it was totally manually operated. The evaporation tube was around 25 feet tall. It would […]
