Modifying a Tower SG90 servo for continuous rotation with potentiometer position sensing, Part 1: Investigation and continuous rotation

Thursday, February 26th, 2015

Keith wrote an article on modifying a Tower SG90 servo for continuous rotation with potentiometer position sensing: On its own, the servo takes power, ground, and a position input and moves the shaft within a range of rotation to match the angle requested on its input wire. It has one or more...

Solar scare mosquito

Friday, July 18th, 2014

Here’s a cool Solar scare mosquito project by Gallactronics.  He writes a complete step-by-step instructions here: So I built a device that generates air bubbles at regular intervals and effectively produces ripples up to a radius of 2 meters (sufficient for most urban water bodies). The device automatically switches on when it...

Friday, August 31st, 2012

[embed][/embed] Check out Alan Yate's video about the Curious-C Beeper: When a capacitor is touched to the probe, the probe beeps at a frequency that varies with capacitance. The frequency change is so steep with capacitance that tiny capacitors may be precisely matched or an exact fixed value may be...

USB Infrared Toy hacking

Wednesday, October 20th, 2010

Siklosi mega-sized his IR Toy with a second wide-angle LED from an old remote. In certain situations the LEDs will compete for current and one will dominate, but Siklosi's video test (after the break) shows them both working pretty well. Grab a regular IR Toy for $20, including worldwide shipping....
