Altoids to test VGA/Audio functionality!
posted March 17 2011 20:22.12 by Giorgos Lazaridis

PIC16F84 is marked as "mature" from Microchip, yet Chris from pyroelectro seems that he has some of these oldies in stock. He informed me about this Audio/Visual tester box that he made based on a 16F84 microcontroller. Chris has gain some experience working with VGA in the past, and this time he wanted to have something more compact and portable.

Housed in an empty Altoids can, there is a 15-pin VGA output to connect the monitor cable for test. Upon start-up, 3 strips appear on the monitor, a red, a green and a blue. Moreover, he has a 3.5 jack output to connect audio devices such as headphones and speakers. A 555 generates a variable-pitch tone, controlled by a potentiometer. This could make a really handy portable tool for PC technicians. As always, a great documentation comes along Chrisís projects. Thanks [Chris]!
