"Here are two experimental "extreme" business cards that are almost impossible for someone to throw away – one in the form of a key ring torch and one card that actually dials me up by itself! This one has a computer inside with more processing power than took the first astronauts to the moon (No, I’m not kidding!), yet the main part costs less than 50 cents. …Even if these
Greener Business has put together a $15 Portable Solar Powered USB Charger with an LED Flashlight project that might appeal to the green person within you. “With this project the thing that makes it really useful is that you can leave the device in the sun, without anything hooked upped to it, then bring it anywhere with you to charge your USB devices, because it’s hooked up to the
Seems like almost anything can be done with a oscilloscope and some determination! Video after the jump. “Star Wars on mame, hacked to render on an oscilloscope driven from the sound card. The dots in the corners of the image compensate for any DC offset, to stop it drifting around the screen.” Via: TechEBlog
Here is a project that you can build to show you some instant stats on almost anything you may want, emails, number of Diggs an article has, CPU usage of your computer, etc. There is a great build log for the project and the creator has released the entire project so you can build your own. You will find source code, schematic diagrams and even the PCB file on his
Tim from Imagitronics has created a cool alarm clock that was just a concept till he spent a few dollars on some parts and created it. “Several months ago, I stumbled across an interesting article on halfbakery.com about the possibility of an alarm clock in which the alarm only sounds when the user is actually lying in bed. The idea peaked my interest a bit. Last week I decided
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
