Spit out VGA with non-programmable logic chips
Bitbanging a VGA can be a tough task due to the timing requirements. Nevertheless Sven gave it a go and not only he bitbanged a VGA on an arduino, but he managed to configured an array of 7400 logic chips to output a VGA signal. Consisting of two parts, his project first consisted in outputting a…

Make a CPLD module yourself!
A CPLD (Complex Programme Logic Device) is a very useful tool in the hands of a techie. Their complexity comes between a PALs and an FPGA, and architectural features of both. As implied by its name, these chips can be programmed to meet the logic functions that suit your needs. In this amazing tutorial, Bill…

Controlling the output of a Papilio Pro with the wheel of a mouse
https://youtu.be/N8pwx4Y7E30 There are tons of ways of creating a home-made microcontroller. Today we present a very detailed tutorial on how to achieve this using the rotary encoder from the scroll button of a mouse. This is part 5 of a series. The goal here is to achieve a constant frequency signal at the output of…
