Youtube user vegmatic1966 has made lots of electronic experimentation videos. The two videos above explain a simple AM Transmitter that uses a 555 Timer and the video below shows off a AM Transmitter that uses a PICAXE microcontroller.
Adam Greig from Negative Acknowledge has developed a nice Nerf Sentry Gun, he used the NERF Vulcan which was the same gun I was thinking of using for my Nerf Gun project which is currently being finished but it was quite a bit more than the knock off that I ended up using. Via: Hack a Day “The gun itself is now running off a 3-cell lipo pack, which about
Tod from ThingM has come up with a cool new product called LinkM. It will allow you to control your BlinkM devices with no dedicated microcontroller. Via: Electronics Lab “LinkM is a USB adapter that addresses two of the most frequently-requested BlinkM features: It enables you to program BlinkMs without setting up a separate I/O board, such as an Arduino. It lets you program or control multiple BlinkMs simultaneously. Plug
The first 8 seconds of this short video looks like a nice little robot with 4 wheels and a raising and lowering center platform. After the 8 second mark this robot shows us what is cool with this robot! As it approaches the first raised step the platform is thrust upward to the top of its travel very quickly, the result is a jumping robot! The robotics department of the
This mbed RFID Tweeter project really shows off the power of the mbed microcontroller platform. With a relativity small program this project is able to read RFID tags and communicate with Twitter to send messages under specific circumstances. The mbed is based on an ARM processor, you can find the full impressive datasheet here (PDF). Video after the jump “Hardware Components For this example, we use: An mbed! An ID-12
Hacked Gadgets Forum user JingleJoe from England needed a power supply for his digital camera. I love that it was all built from bits and pieces laying around. I have used some creative heat sinks such as a section of an old junction boxes when free air was just not quite enough but I have never used a piece if a tin can. I will have to keep that heat
If you have ever set the wrong fusebit when programming your AVR have a look at this AVR Fusebit Repair Circuit which could help you repair the chip. There is also a parallel high voltage version to have a look at. Thanks Pawel “Did you make a mistake while programming fusebits, or purposely disabled reset pin (RSTDISBL) or ISP programming (SPIEN)? No need to buy or make inconvenient HV programmer
