ATtiny25 Basic VCO, RC oscillator overclocking and testing frequency pickup

Monday, June 17th, 2013

Alex over at InsideGadgets has posted an article describing how he built an ATtiny25 voltage controller oscillator (VCO): I recently bought a Rigol DS1052E and have been playing around with the different functionality it has. Eventually I came to the point that I’d like to see what frequency does to various...

AVR microcontroller based PWM fan controllers

Monday, March 4th, 2013

Zak Kemble posted his AVR based PWM fan controller build: So this is a bit of a continuation on my 555 timer based PWM controllers, but now using microcontrollers and MOSFETs instead of 555 ICs and transistors. I made 2 versions, one with switches for speeding up and down and...

Clock source for the EasyDriver

Friday, December 2nd, 2011

Henrik designed and built an adjustable clock source for the EasyDriver that maintains the same motor speed over a range of step resolutions. It adjusts the driving frequency depending on the resolution of steps the EasyDriver makes per input pulse. EasyDriver is a stepper motor driver that moves the motor...

Logic Sniffer: RC transmitter module design debug

Wednesday, October 5th, 2011

pppd created a removable RC transmitter module based on ATtiny25  with the Logic Sniffer. Annoyed by an uncomfortable RC transmitter design and its stick mode, pppd decided to build a removable RC transmitter. It works by converting the standard RC PPM into the IR signal used by the toy. But first he needed to reverse...
