Linux Analog to Digital Converter via Parallel Port

Posted November 30, 2014 by Chris

"It can be a little expensive to read analog signals, for example temperature readings or light levels, into your computer. In this article we will show you (1) how Linux can use a computer parallel port and a $10 integrated circuit to read 8 analog channels at 12 bit accuracy, and (2) how we used this to build the Extreme Comfort System."

Real proof that computers are becoming so small we can barely see, let along use them is this linux desktop cube. It’s no larger than an apple and yet can run linux just as well as any other desktop. Just get your hands on the hardware in the parts list and you can make your own!

Linux Pic Programmers

Posted September 20, 2009 by Chris

Anyone who deals with embedded systems is bound to run into or frequently use Linux, so being able to cross-develop on Linux can be very handy. These few articles give you some insight into how to get started programming with the PIC & Linux environment.

Solar Station Server

Posted October 23, 2008 by Chris

Here is another interesting linux based project, although seemingly a tad overkill. This project takes data from a solar station and e-mails it to you at intervals you chose (i.e. once-a-day). The project write-up is very detailed from all aspects. Definitely worth a read.

ATMEL AVR on Linux

Posted October 17, 2008 by Chris

If you’re a linux guy and have always wanted an ‘in’ to the world of microcontrollers then this article/guide is for you. It’s not really a project so much as a very well written how-to develop for Atmel’s AVR using the linux gcc compiler. A great alternative from the Windowz world.
