Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow for much ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

So my PC was noisy and I invested in 120mm Akasa Apache fans. Now I have 4 Apache fans (2 on the CPU cooler), 1 sucking the air out at the back and to balance the pressure, one Apache blowing cold air ...
