Check out this 555 Timer Chip Scroll Music Player, it uses scroll that has a bunch of slots cut into it so that metal fingers can selectively touch a contact under it. A rolling system pulls the paper past these fingers and plays music since each contact has a different resistor value connected to a 555 timer. The construction looks great since you can see all of the components.
This Papercraft Lamborghini Aventador shows us that the possibilities of Papercraft are endless! Makes me want to get some sheet metal going to build one that I can drive. “Overall I am very pleased with the final outcome of this experiment. I learned many new lessons and the artwork makes a great display on my wall. The completed model measures 8′ x 3.8′ x 2.1′ (627 x 244 x
If you have a laser cutter or CNC machine you probably have a Cable Carrier Chain (or want one). They are quite expensive but with this DIY Laser Cut Cable Carrier Chain project you can simply make your own if you have a laser cutter. Martin Raynsford wanted to add one to his laser machine but didn’t have the time to wait for one to be mailed. You can
 ScratchBuiltAircraft had some extra parts laying around and decided to slap together a quick RC Hovercraft. It looks very controllable even though the control system is a simply small serve that deflects the air. Looks like the heavy duty garbage bag does a good job and sure keeps the cost down!  “Electronics: 70mm EDF 60amp ESC 1x 9gram servo 4cell 3000mah LIPO Battery Deans extension Turnigy 9x  TX/RX
 If you want your next project to have a wow factor why not make a glass PCB! You can see how CNLohr makes them in the video above. A glass microscope slide is what the circuit will be made on. He puts some UV activated glue on the slide and sticks some copper leaf on it. A UV eraser is used to cure the glue so that the slide
If you need an easy way to control the light color of your strip lights this weekend project uses an android phone to send data to an Arduino via a USB cable. You are able to select various colors on the android device and have the LED strip instantly display what you are doing. I think using an Ethernet connected Arduino and a WiFi app would make for a
With gold worth some serious money and lots of throw away electronics it seems that gold scrapping is more popular than ever. Seems like people are even making a name for themselves like Scrapper Girl.
