Here is a simple mod to allow the speed of any 12V fan to be varied. All we need to do is insert a rheostat or variable resistor in the 12V wire to the fan. The rheostat should be rated at least 3 ...

I have a Darlington transistor to keep cool. It is a lovely chunky TIP147 in a TO247 package, attached to a PC heatsink (£6 from ebay) to get the heat out. PC heatsinks are great as they often include ...

The temperature-controlled PWM boost converter in Figure 1 allows operation of a 12V brushless dc fan from a 5V supply. The circuit is based on IC 1, a single-chip ...

Noctua has today announced its NA-VC1 24V DC to 12V DC step-down voltage converter allowing for users to run standard 12V fans in 24V environments such as 3D printers or industrial and automotive ...

This circuit idea is certainly not new, but when it comes to making a trade-of between using a small, short-circuit proof transformer or a capacitive voltage divider (directly from 230 V mains voltage ...

I was pondering possible interfaces between a microcontroller and a 12 or 24V 5015 blower fan. The challenge is that the MCU can only drive 3.3 or 5V, while the blower needs needs a voltage as low as ...

Most of us using desktop computers, and plenty of us on laptops, have some sort of fan or pump installed in our computer to remove heat and keep our machines running at the most optimum temperature.

Diodes Inc.has announced the introduction of a pair of all-in-one single-phase 12 V fan motor drivers for low to medium voltage brushless DC fan control in consumer, home appliance, industrial and ...
