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
Keith Baxter from the The Milwaukee Servoelectric Guitar Project sent in the cool progress he is making on the Single String Servo Guitar project. You probably remember Keith from the original Servo Guitar that we featured last year. There is something haunting and pleasant sounding with this new single string guitar, I wonder if Keith could rig something up so that it could pick the string and control the servo
Check out this sweet motorcycle GPS and temperature display that came out of HeatSync Labs (cool name by the way). Nice thing about the system is that it could be modified to monitor all sorts of motorcycle sensors. Via: Adafruit “The components used include these: Arduino Duemilanove Adafruit GPS logger shield kit USGlobalSat GPS Module Standard LCD 20×4 Breadboard Power Supply Polycarbonate Electronics Enclosure“
So you need to hear the secrets that are being spilled in the building across the street? If the conversation is happening over the phone you could build a DIY Telephone Listening Bug and tune into the conversation on a radio but what if the conversation is happening between two people in the room? The answer is a Laser Listening Device, we have featured one of these DIY Laser Listening
Who says that cool things can’t be made using bubble gum and Popsicle sticks. 🙂 This PIC Microcontroller Based Writing Robot is much more than a collection of gears, drinking straws and string, watch the video as David who built the robot is able to make the robot draw with a pen.
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
