In this tutorial we will see how to make a Magic 8 ball with the Arduino. This is based on the real magic ball which is based on liquid and floating principle with a plastic dice with 20 answers inside. Once you shake the ball, a random side of the dice will get on top of the black liquid and a r... view more

This is a prototype on a Variable Frequeny Driver or VFD. With this circuit we would control the frequency of high AC voltage and by that the speed of induction AC motors. Since we work with high voltage, is a dangerous circuit so be careful. The idea is to turn 230V AC voltage to DC vo... view more

I was waiting for this service for some time. Alo, the price is very low cost so now we can get the PCBs and all the components already soldered for just a few dollars per PCB. So, we could sell our designs and that's awesome. This will help our community a lot. So, this is what you need to know ... view more
