Arduino radar using sound waves
A radar system uses high frequency radio waves for object detection. A high-power RF pulse is transmitted into space and its echo reflected off from an obstacle is recorded. By computing the time elapsed between the transmitted and reflected pulses, and knowing that the electromagnetic...

Using VL53L0X With Arduino to Measure Height
Usually, when measuring a child's height at home, a mark is drawn on the wall then the height is measured using a measuring tape. This process is not always easy and it may has low resolution. In an attempt to simplify this procedure, a new project was developed using an Arduino and a...

Reverse engineering a server CPU voltage regulator module
Andy Brown wrote a detailed article on reverse engineering a CPU voltage regulator: A recent ebay fishing expedition yielded an interesting little part for the very reasonable sum of about five pounds. It’s a voltage regulator module from a Dell PowerEdge 6650 Xeon server. I...

Sonicare toothbrush teardown: microcontroller, H bridge, and inductive charging
Ken Shirriff did a teardown of a Sonicare electric toothbrush: The photos below show the top and bottom of the toothbrush internals. I expected to find a simple, low-cost mechanism, so I was surprised at how much complexity there was inside. The vibration mechanism (right) is built...

230V AC dimmer, mains isolated, using PIC12F629
This is a very simple mains isolated dimmer with a triac output (phase control). It uses timer0 to do the timing. There is no user interface, the value of the triac ignition delay after a zero crossing is defined by setting the reload value of timer0 (Tmr0) in the software...
