Ever wonder how to remove surface mount electronic parts from a board? This video demonstrates the clothes iron method, as opposed to the cooking skillet method. 🙂 If you have some tinfoil you may want to give this method a try. Here is an english version, thanks Nick.
Want to add a touch of cool to your next PIC microcontroller project? Why not have it play some ring tones. There is full source code and an explanation available. “Using only a speaker and decoupling capacitor, it is possible to generate tunes or melodies from your Microchip PIC16F87x processor. A timer can be used to generate each of the eleven musical notes and another timer can be used to
Valojuova from Finland has created a crazy DIY invention for cooling a can. The Peltier CAN cooler uses the peltier effect for cooling. Looking to cool a bit more with a peltier device? Check this out. “PWM controlled peltier cooler, 12V, 80W peltier. I can holder was lathed from aluminium by some other students. I just gave him the blueprints. Hot side is cooled with Igloo 7200 Light. I haven’t
Seems that there is no end to the inventiveness of people out there. Kees Ricken has hacked his USB drive into something unique. “After about 9 months of use my Apacer Handysteno USB-memory stick casing was damaged so badly that I decided to make a new casing. But what to use… So, I went looking in shops for something that I could use as a new casing for my memory-stick.
Fast MHz has made another EM rocket. You might remember their other EM projects from a few months ago. “Hi all…after seeing my gauss gun appreciated here, I figure I’ll share my latest gadget: EM Rockets! That’s right, “rockets” launched with nothing more than electricity. Unlike gauss guns/coilguns, which are reluctance based, these are induction based…electricity goes through a coil, which imparts a current into aluminum, which then itself becomes
Interesting CD changer contraption. I am all for automating boring processes! “The software for this gadget is relatively simple. I wrote a simple command line driven program that sequences the machine through picking a CD from the tray and dropping it in the middle, and piking up a CD from the stack on the left, and dropping it in the tray. The software also has some manual controls, which I
Here is an interesting video of how a microprocessor is made. “Microprocessors normally serve as the CPU in a computer system and are basically “digital electronic component[s] with miniaturized transistors on a single semiconductor integrated circuit. Microprocessors made possible the advent of the microcomputer. Before this, electronic CPUs were typically made from bulky discrete switching devices (and later small-scale integrated circuits) containing the equivalent of only a few transistors” Via:
