En route to getting the off-the-peg DC-51 motor speed controller to better suit my small milling machine, I had a go at working out what the circuit is. Approx circuit of DC-51 motor speed controller ...

TORONTO/NEW YORK, Feb. 10, 2012 /CNW/ - Micromem Technologies Inc. [the "Company"] [OTC BB: MMTIF, CNSX: MRM], through its wholly owned subsidiary Micromem Applied Sensor Technologies Inc. ("MAST"), ...

I bought a small old and rather battered milling machine. It is a Sieg X1, painted yellow and sold as a Clarke CMD10 in this case. These are basic machines built to a price and tend to be rather ...

The motor-speed-control circuit in the figure shows an SG3524 pulse-width-modulation (PWM) IC, U2, driving the high side of a motor through a p-channel FET, Q1. The motor terminal voltage is more ...

High-speed circuit design is one of the most fundamental, yet challenging areas of electronics design. High-speed circuits are commonly used today, as standards like USB, HDMI, and PCIe require most ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

This post is a quick sequel of my previous article jam-packed with my personal experiences and observations while I was fiddling with standard 4-wire PC cooling fans. Today I will be talking about the ...

A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...
