Schematic & Connection Diagram


the mosfets i use are from a laptop's broken motherboard
i found the FDS8884 N-Channel.. the most fast switching mosfets are ok...
also you can take a look the datasheets for each one you find
Solder the Mosfets




solder the mosfets and the 2x 10k resistors
Test the Circuit


i test it with 24v power supply and a powerfull motor
* You must use a fuse
* Never turn on both of two inputs
Put a Heatsink




if the load is big put a heatsink for better results
always look the datasheets for voltage and amperage
Ready

its ready..
you can use it with microprocessors (PIC/Atmel) arduino, rc cars or for any project..
