Rustic Engineering has some good posts about the GUI Bot build, it’s a robot that is based on the PIC18F452 microcontroller. The robot looks great with two large drive wheels and one coaster wheel under the front. You can also find a large writeup of the project over at Lets Make Robots. “Feature List Move, turn and gyro with speed and agility; Speed up and Stop when you need; Generates
Sacha De’Angeli from ChemHacker has released the schematics and source code of the Scanning Tunneling Electron Microscope. The STM is Arduino based and has been a build in progress for quite a long time now. Looks like it is at a great state now! See the Wikipedia page for more generic information about Scanning Tunneling Electron Microscopes. “The STM is based on the concept of quantum tunneling. When a conducting
Jason sent in his latest creation, it’s a 1.25kJ Coilgun. Check out the cool video of it below, you will get a good overview of how it works and see it in action. I like the fact that he is re-using some parts in the build like the cell phone charger for some of the low voltage circuit needs. By the looks of the damage caused by the gun I
Instructables member drj113 has put together a powerful Networked DIY Watering Controller. It has a AtMega168 at its heart and uses a RTC to keep accurate track of time. Where I live there is no restrictions on lawn watering but this is a good flexible system that can save you costly fines if your area imposes lawn watering restrictions. “The sprinkler controller is built on the base of my Adruino
Have a look at this cool project that our friends from Gadget Gangster put together. It is called the Web Clicker, it gives you an easy way to control IR devices from any web connected device such as an iPhone. I think I could through a wench into the demo with an IR Jammer though. 🙂 “The Web Clicker is a web server & IR transceiver. You can record any
Ben Heckendorn is known for his crazy hacks like the XBox 360 Laptop. He is hosting a web show on Revision 3 called The Ben Heck Show. The show will be broken up into 2 types of builds, he will be taking suggestions from the audience and he will also be covering a large build that will be covered over many episodes. I wonder how he got the suggestions for
Wellyb00t has built a cool Analog LED Clock based on a PIC 16f877 microcontroller. Given the complexity of the hand wiring the spiderweb of connections on the back of the board is beautiful. You can see more pictures including the schematic here. “*12 Dimly lit leds on outer ring showing clock outline. *LED test on powerup *16F877 PIC Microcontroller @ 20MHz *DS1307 Real Time Clock for timekeeping *169 x 700mcd
