“A stepper motor is a brushless, synchronous electric motor that can divide a full rotation into a large number of steps. When commutated electronically, the motor’s position can be controlled precisely, without any feedback mechanism” (citation from Wikipedia) Any DIY Maker should understand the workings of stepper motors, Ask any Robot maker, just about any motion control a robot makes is done with stepper motors. Here are a few links
This Flexible-Jointed Robot has amazing stability. I could see this thing walking down a battle field or working in a construction site stepping over piles of debris. “If robots are going to work alongside humans, then they will need to stand up to accidental bumps and shoves, not to mention the occasional deliberate kick. That is why researchers in Japan have developed software that allows a life-size humanoid robot
Interested in building your next audio amp, before you do have a look at some builds so that you can see what you are in for. This AMP6 looks like a fun build. “The AMP6 is a small amplifier that uses the Tripath TA2020 chip and includes an onboard regulated power supply. The manufacturer, Tripath Technology, Inc. describes Class-T amplifiers as offering both the audio fidelity of Class-AB and the
Using a PIC microcontroller and a accelerometer this toy car has been turned into a fun balancing robot. About half way through the video the car is violently pushed back and forth, either the best recoveries were captured and displayed or the recovery code is very impressive! Here is a video of the car before all the refinements were put in. 🙂 Does anyone know if there is a
Above image is a B9A Nixie Tube Tester & Regenerator that tests and removed cathode poisoning. The B9A Nixie Tube tester is just one project from Tube-tester.com web site. The site is in German and English and is hosted by Dieter. This site is one of the foremost resources around for Nixie tubes, antique tube testers and Nixie tube specifications. Dieter collects data sheets of Nixie tubes from all over
You read the title right, you can make thermal grease using diamonds. Have a look at this Diamond Thermal Grease article that demonstrates how to do it. I would have thought the diamonds would have been very expensive but apparently you can buy 25 Carats of diamond dust for about $30.00 on Ebay. Of course if money is no object you can make your own diamond dust. Destroying a diamond
