Roger writes – This tutorial offers suggestions about controlling large loads with a microprocessor. This is often an issue with those building robots who need to control devices such as lights, motors, vacuums, and other accessories found […]

The entire detector is built around a laser pointer, a few hobby-type mirrors, a PIN photdiode, regulator and amplifier, enclosed in […]
LeorickSimon writes in – Using your old phones, you could create personal “micro” telephone exchange as simple as above circuit. I manage to solder the test circuit less than a minute. Than connect the phone and test it. It works. So why 39 ohm? From Epanorama Dot Net, the correct value of the resistor should […]
Frank made the coolest clock, ever. He writes – A while ago, while surfing the web I found an interesting idea for an oscilloscope clock. I have spend some time thinking about it first, and finally decided to make one myself. First I made a crappy version with a R2R resistor ladder network for a […]
