David Cook from the Robot Room has Reverse-Engineered the PCB for the Big Trak Toy. This is a toy that was built in the late 70s. It is interesting to see how things worked 25 years ago! “The motherboard is single layer/single sided. There are between 8 and 10 jumper wires acting as second-side traces on the component side. The PCB does not include a silkscreen (printed layer), so the
This is an neat little solar robot that would be cheap and easy to build. “Make your own solar powered robot at home using things you probably already have. Transistors, resistor, capacitor, solar battery and flashing LED are available at any electronic store, if you don’t already have them. Solar cells out of calculators work as well, you might want to use more than one since they are really small.
I am not sure I have the guts to test this Electronic Parasite Zapper but it is novel idea. “The two coper pipe electrodes you hold in your hand enables the low voltage at certain frenquency to penetrate your body ,thus killing parasites and other bad organisims, although it may not be exsplained properly, but through exsperimentation of this circuit i accidently found this may be the electronic version for
This robot can solve the Rubik’s Cube faster than most people! “What’s the point of having robots if you’re not going to make them solve Rubik’s Cube puzzles?! With all the unsolved Rubik’s Cubes puzzles there are all over the planet i think it’s every governments responsibility to send wave after wave of these robots into cities, streets and into peoples homes, searching out every last unsolved Rubik’s Cube puzzle
If you want to keep cool while using your computer give this mouse mod a try. If you still need more cooling this USB shirt may be the answer. “It’s not too hard to add a small DC fan to a computer mouse. The plastic housing for a mouse, especially on older ones, is usually wide open in the back. Put a fan in the back to keep your hand
Ever want to change the color of your optical mouse? “This mod is very easy to do. It took me about 15 minutes from start to finish. Blue IMO looks much better than the red before. Much easier on my eyes. The skill level to do this mod is pretty low. The only thing you need to know how to do is solder, which is something that anyone can pick.
This article goes through the steps required to photo etch your own copper clad circuit boards. There is a relatively small amount of hardware that is required and the steps are quite simple. If you have done the toner transfer method in the past why not move to the next level? If you are thinking of making your own circuit boards there are a few option: * The easiest is
