A True Random Number Generator seems to be a mathematical myth. However, we can still get pretty good random number generators. This AVR uses noise sampled from a transistor in the breakdown region which should be seemingly random. The schematic layout & source code is available in the project write-up!

While surfing around I ran across the Z80 Text Scroller by Tim Williams. Tim's website has a lot of his personal projects and they all have the DIY feel that I love. Take a look at the text scroller and his site, hardware schematics & software are there as well!

The PICAxe serial keyboard was built to interface with a XENIX computer. It is fairly custom when compared to the way keyboards work now-a-days. However, I felt the project was noteworthy enough to take a look at. Hardware schematics & software are available for download.

This project uses a 12xx series PIC to control the rear light to go on a bicycle. The main function is for when you are riding your bike at night so people can see you. Hardware schematics, PCB layout & software is all there. Avid bicyclists don't miss this one!

This drop-dead simple project uses a SR87 GPS module and an AVR to understand the data. Then that is output onto a simple 16x2 character LCD. The hardware schematic and software is all there!

Similar to the ARM Index I showed you a few days ago, this is a vast AVR project index. No matter if you're a beginner or a pro, you'll get ideas and sample source code from this resource. All AVR guru's should have this website bookmarked. Don't miss it!

This very detailed write-up goes through the process of designing a vehicle monitoring and security system. If you don't mind the lack of pictures and prefer schematics this article is for you. It's all brought together using a microchip PIC as its CPU. Some advanced components are used in this design. Check it out!

Today while I was looking around the inter-webs, I ran across this psuedo-ARM project index. The index is mostly an assortment of example programs for the more advanced features like timers & interrupts. Definitely worth a look if you need more ARM example code to look at.

Dubb'd the 'Ypod'. The YAMPP mp3 player is the pinnacle of many DIY mp3 player projects combined. It uses all off-the-shelf components, you just need a fab'd PCB board. The entire project is open-source, hardware and software so go take a look!

If you've ever been interested in the Arduino microcontroller here's your chance to get a sweet little dev board for free. Uchobby has a giveaway program that is still in action. The board itself is probably not worth more than $20 but it is still worth at least a quick look.
