Check out the latest Analogue to Digital Conversion Interrupts on an ATmega168A tutorial over at Protostack. You might not need the information today but it will probably come in handy some day! “In this tutorial we add a second analogue input and use the ADC Conversion Complete interrupt. The circuit we are using is similar to what we used last time but has an extra trimpot and uses an ATmega168A
Want to control an army of robots with the sound of your voice? Well have a look at this Speech-Controlled Arduino Robot for a good head start. Carlos Asmat has done a great job with the video that shows how everything goes together. “For this project, I used the DFRobotShop Rover (a mobile Arduino kit), the VRbot speech recognition module by Veear, two XBee modules, an Arduino Uno, two XBee
Jessica Bethune, Aiswary Kolisetty, Jessica Noglows and Rob Sobecki built this Master Lock Cracking project. I could have used this in junior high when I forgot my combination and needed to get my lock cut off. There is a mechanical spinner and a puller, the rest is all PIC microcontroller code. “The PIC was required to interface several hardware components to crack open a MasterLock with our LockCracker. The PIC
At first glance you would think this was a normal remote control vehicle with two wheels but you would be wrong because the rotating wheels aren’t actually touching the ground. This Angular Momentum Experiment by from JCOPRO.NET shows us the results of some experiments made from some scrap parts and some household items. Via: Hack A Day Comments “This was pretty much thrown together, so I won’t lay out the
Gauss Weapons are lots of fun because there is some cool science making them work. At first glance it doesn’t look like anything special would happen with the typical Gauss Gun setup. As each magnet/ball bearing chain is reached the energy and speed increases. The effect is stunning because there is no explosives or electrical energy being used, just some normal magnets and the Gauss Gun setup is all you
When you are laser etching some stuff there isn’t much contrast in the end result. There are rub on products that you simply buff off the excess. Only issue is you have a short working time before it is on everywhere for good. I am all about using products that you already own and didn’t know it could be used in a new and creative way. That is exactly what
Our friend Carlos from Carlitos’ Contraptions has joined the Aldebaran Developer Program, they make the Nao humanoid platform. Thanks to Carlos we will get a first hand view into how this robot works and what it can do. At $16,000 it isn’t a toy but as a humanoid development platform that is a decent price. It reminds me a bit of the RoboSapien but is much bigger and has a
