An oscilloscope is a type of electronic test instrument that allows signal voltages to be viewed, usually as a two-dimensional graph of one or more electrical potential differences (vertical axis) plotted as a function of time or of some other voltage (horizontal axis). Although an oscilloscope displays voltage on its vertical axis, any other quantity [...]

In this post, TechshopJim will show you how to etch a circuit board with about a tablespoon of ferric chloride etching solution and a 2 inch square sponge. You will be amazed as the exposed copper on the PCB disappears before your eyes, and your board is completely etched in a minute or less!

This method is generally restricted to making through-hole component PCBs. I don’t usually like to use veroboards because in my opinion, they look ugly most of the time. For more complex, professional looking boards, I normally use the toner transfer method.
The good thing about this quick method is that it still looks decent on the [...]

This document is not a tutorial on how to use EAGLE, although it’ll probably be somewhat useful in that role. It’s more about how to configure and customize an Eagle installation to better suit the hobbyist.

This project shows the creation of a large array of UV LEDs. They are used to expose a presensititised blank circuit board. Another common method is to use UV Tubes. He used to make the isolation box: 54 UV leds buyed from E-bay for about 15 $ 18 resistors 68ohms, 1/4Watt for 0,60 $ 1 [...]
