 NAND Gates are very versatile. You might remember back in the TTL days when you were out of a specific chip you could always grab a NAND chip out of the bin and re-purpose it to work. This NANDputer looks like it would be a bit harder to troubleshoot than the one that I am using to write this on! “While the CPU architecture is fairly conventional, the
Thanks to Jerod Michel for sending in the details of this Armed Mobile Response RC Car that he and his students have built. It can be driven around remotely, it has an audio and video range of 100 meters. If you spot something you aren’t pleased with you can paint your target with the laser and fire the vehicle mounted gun. I have to admit, it is quite strange to
Here is an example of Screen Printing PCB Manufacturing. It is very time consuming but your PCB factory could make screen printed t-shirts on the weekends. 🙂 It looks like they are setup for medium volume but it looks very time consuming compared to modern PCB manufacturing.
Kerimil sent in a method that he is using to get data out of his Arduino projects to the net using an Android phone in the middle.

The initial GUI reminds me of the Visual Studio environment where you can drag and drop elements such as check boxes and buttons but the language looks very

This Cardboard Cube Lamp looks like a fun project. Make sure your light source is not very hot though! This can be made using an exacto knife but I am thinking that you could make some great looking shapes that would be easily repeatable with a laser machine and some scrap cardboard boxes.
If you have a Baofeng UV5R Ham Radio and want to get the most out of it have a look at the reverse engineering work Lior Elazary has done with his. The radio is very powerful as it is but when hacked, the sky is the limit on what you can do with it. Lior has many pages of information and code that he has used to hack this
