As a follow up to one of my earlier projects, the Variable regulated power supply, initially designed to deliver 0..30Volts at up to 10Amps, I have decided it was time for an upgrade. I kept the enclosure and the nice 250W toroidal transformer, and am reshaping everything as a new digital power supply with regulated voltage and current, short circuit protection, lcd display, buzzer for various alarms, temperature sensor on…
A short review on my new Christmas gift, a neat digital soldering station, ZD 937, and a quick light installation that I did with LEDS, running directly on mains , 220V, using the ZD937.
A digital dosimeter design that can be used with multiple geiger tubes, constructed around the atmega8 microcontroller and a 2×16 LCD. Equipped with a radio Bluetooth module for remote operation.
Use the Atmega8 with two temperature sensors: the DS18B20 and the DHT-11. The latter also offers relative humidity data.
