This is a simple and effective switched mode power supply (SMPS) that I built to power a LCD monitor that I fixed a while ago. This one requires 20V at 2. 3A, but the PSU output voltage can actually be set in the range 1. 2V - 25V, with a small variable....

For simplest functions (flashing indicator and/or beeper) you don`t need a printed circuit board, directly weld onto the legs of the PIC, an end of heat-shrinkable sleeve and that is. Go ahead with softness if you do not want to burn the integrated circuit....

Would it be possible to remove the ESCS from a multicopter setup and replace them with a 1 single circuit board to throttle all the engines? I have a 8 motor setup wich is 8 ESCS wich is 8times the way and 8 times the possibility of failure or broken down....

Programming the GPS Disciplined Oscillator (GPSDO) with the QP state machine framework -, which I badly need to write up - has led to the conclusion that I`ve run out of SRAM on the the Arduino Mega 2560 system. Not surprising given that there`s only(!) 8 kB....

Originally I was going to call this posting "Crystal Oscillator Blues". This is given because things have not been going well with constructing the crystal oscillator for the GPS Disciplined Oscillator, as outlined in my last posting ( GPSDO - Crystal....

Ever since the best decade of all time, the 1970s, people have been able to buy amplifiers in all-in-one chips rather than having to make them out of lots of discrete transistors. This video shows you the basics of op amps and has an example circuit where....

Afroman covers the basics of how transformers work, where to shop for step down mains transformers, and how to wire one up to mains voltages without killing yourself. European and North American wiring is discussed. He finishes up with a quick example of AC....

The HandyBoard drives both pads at the positive supply of the battery. When one of the motor is supposed to turn, the handyboard drives the appropriate pin at 0V. The difference between two pads makes the motor turn. The Transistors are TIP 120 and TIP 125....

PIC16F778A is widely uses now and it is also famous among the beginner until all theprofessionals because of the FLASH Memory technology which can be write/erase within a tousand times of programming. Speed and code compression are the superiority of this....
