DIY Electric Vehicles are catching on, Instructables member MPaulHolmes has designed and built this 100 HP DIY Electric Car Motor Controller. You normally see the technique that Paul used when you make a circuit board on a CNC machine. But the reason so much copper was left on the board is because the board is used as power distribution within the controller instead of bundles of wires. So what sort
John from Crazy but Able built one of those Smokey Guitar Amps and demonstrates how it sounds with his guitar. The Smokey Amp plans are from Dirtbox and is designed to use those strip proto boards. With only a few components you could build it and be playing it in a few hours. Chances are you have all of the parts you need in your junk box. John modified the
Have you ever wanted to determine how fast something was turning? With a few parts and a microcontroller, monitoring something spinning is a simple task, you just need a way to get an input into the microcontroller so it can count pulses. In this case Chris from Pyro Electric used an infrared beam to monitor a spinning fan, as the fan blades turn they interrupt the IR beam made using
Looks like these Reverse GeoCaching projects are getting more and more popular. We have seen this type of project before but this one is much more of a cool hack than the others. In this project a GPS receiver with a SkyTraq Venus chipset was used but apparently was not that easy to work with. Full schematics are provided if you are interested in making your own. Thanks to our
If you have a Acura NSX in your driveway and are getting a bit bored with its lines. Why not not make it into a $550,000 Farrari F50? Not sure if this was a conversion by owner or if the owner hired a shop to make the changes. I could just imagine the reaction the owner would have had if he showed up mid way through the project and saw
Kerry Wong needed a way to determine distance in a project. A popular way to do this is to use ultrasound. Kerry is sharing his experience of building his DIY Ultrasonic Range Sensor so that the rest of us can learn from what he built. Parallax has a product called PING which is a popular way to allow your project use ultrasound to measure distance also. Only problem is when
Deddie Lab has two interesting Secret Dice projects, this one is the original but there is also a metal one that Deddie has since made. The object is to get inside the box, no smashing the box on the ground doesn’t count. The boxes have a secret code stored in them, to enter the secret code you must tilt the box in the correct ways to enter the code. When
