This DC Motor Multiplexer allows you to control up to four DC motors in forward and reverse using one MOSFET and only 5 digital pins. For this intractable you will require: – DC motors (I used salvaged DC fans)– MOSFET (I used a 110v 30amp make sure it is rated for more than your combined […]

This simple DC motor controller allows for one direction motor control and has been built entirely of reclaimed electrical parts. Using MOSFET’s for motor control instead of control chips, allows for an external power supply and electric isolation of the motor and control board. Which allows for the use of higher voltage and amperage motors

A Temperature Controlled DC Fan is a system which automatically turns on a DC Fan when the ambient temperature increases above a certain limit. Generally, electronic devices produce more heat. So this heat should be reduced in order to protect the device. There are many ways to reduce this heat. One way is to switch
