Ever wonder how induction heating worked? Me too… Penguin Labs has an informative article about some of their experiments. “Induction cookers, furnaces, stoves and all that jazz are now widely used. You put your metal saucepan on top of an innocent looking glass plate and it magically heats your food with no flame and almost no waste heat. They are able to heat certain metals up to their melting points,
This RF Remote Controller project is very well documented and even has a step by step explanation of what the PIC microcontroller code is doing line by line! “On these pages, I will introduce Remote Controller with Radio Frequency. The electric wave sending-out is controlled with the code by PIC for transmission and the code is deciphered by PIC for receiving. The 2 stages FET amplifier is used for the
Want to be a DJ? You can go hands on with a modified Wiimote called the WiiJ. But when you get serious the Kuka industrial robotic DJ is the only way to go! Videos and more pictures after the jump. “The Juke Bot is a pair of Kuka industrial robots; each is surrounded by a set of platters (you know, vinyl LPs). The two bots act independently, deftly grasping an
Here is an digital audio project that uses S/PDIF. “Here’s a very trivial S/PDIF transmitter hack for portable MiniDiscs and other digital audio devices lacking S/PDIF output. The s/pdif transmitter runs from +5V, 44kHz 16bit input at 384xfs, is set to consumer mode output, and doesn’t transmit any COPY bit (copyright protection disabled). The board can be connected directly to a PC motherboard, or via a Toshiba TOTX173 to an
Here is a list of 5 cool coil guns, either one would be fun to try out. Remember that coil guns can be dangerous, if you build one and shoot out your eye don’t say you weren’t warned.
Using an old serial GPS the guys as Semifluid have made a home made GPS data logger on the cheap. As usual schematics and directions are on the site. “This project focused on creating a simple serial data logger for the Delorme Tripmate (also known as the GPSTripmate). The Tripmate is an older GPS receiver that can be purchased on eBay for
Once the full scale version of this car is made all it will need is a paint ball gun to keep the bad guys away! “Build a security robot that can be controlled and viewed over the internet. The planned final version will be a kids 48” electric car with a network camera attached. 1/4 Scale Trial Version: I opted to try this out with a $20 RC car from
