How to build a Tesla Coil
Unlike some other high voltage experiments, a Tesla coil's streamers can be very harmful. If you are shocked by the streamers, you will not feel pain, but your circulatory and nervous system can sustain severe damage. DO NOT TOUCH IT WHILE ON UNDER ANY CIRCUMSTANCES . Also, I don't take any responsibility for you hurting yourself. This isn't to say that you shouldn't get into high voltage though, its just that if you are planning for this to be your first HV project, its a little to involved.
In my work desk, I have these loose cables coming from below that allow me to connect some of my gadgets to their corresponding chargers: One is for connecting my Nokia N80, the other is to connect the Bluetooth headset Nokia BH-210 . The grey USB cable is connected to a 4-port Hub where I connect some other gadgets such as my printer, a mouse and the iPod dock that you can also see on the image. This way, I can have all of these connected to my laptop by just using one USB port. The problem with these loose cables is that they are loose…obvious, right?

SMT Soldering–It’s easier than you think! is our new Manga Comic that shows you step by step tips and techniques for learning to solder SMT parts . We’d love to get your feedback on the comic.Circuit Simulator Applet
This java applet is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage.
Instead of a weekly order, 2 layer circuit boards are now sent to the fab when the panel fills up. This means panels are going out 2 to 3 times a week instead of just once a week. New ordering website!

A few years ago my wife attended a Papier Mâché (paper pulp) art class. She taught the rest of us one technique called layering. In this technique you glue small pieces of paper inside or outside a mold in layers. You can glue a few layers at a time, let it dry, and add more layers. At the end you can leave it as is, paint it, and/or lacquer it. Once you have more than about 7 layers, the object becomes quite stiff and strong.
