" Not discontinued, you understand, just on a 52-week lead time. " —Dan Mills

A multimeter is an electronics testing device that, um, tests multiple things, including resistance, voltage, and current. Using certain multimeter models, you can test to be sure that components — such as diodes, capacitors, and transistors — function properly. You can also troubleshoot your circuit to see where current is failing and pinpoint the problem spots.
You can see that there are various bits represented by symbols, all connected in various ways. Let’s look at some of the big picture concepts: Left to Right: The first thing to notice is that you read the schematic left-to-right: the input on the left feeds the signal through parts and pathways in the middle to an output on the right.
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.
A few years ago MIT created a system for transferring power wirelessly. They transmitted power over a two-meter distance, from the coil on the left to the coil on the right, where it powers a 60W light bulb. Back in 2006, this was a pretty cool thing.
Unlike some other high voltage experiments, a Tesla coil's streamers can be very harmful.
