Connectors. Making PCBs. How to make really really good homemade PCBs Note - this article is original material.
There is currently a plagiarised copy of it on the site of an Indian electronics magazine credited to a rip-off artist called Indrani Bose. This page is a guide to producing consistently high quality PCBs quickly and efficiently, particularly for professional prototyping of production boards. Unlike most other PCB homebrew guides, emphasis is placed on quality, speed and repeatability rather than minimum materials cost, although the time saved by getting good PCBs every time usually saves money in the long run - even for the hobbyist, the cost of ruined PCB laminates can soon mount up! With the methods described, you can produce repeatably good single and double-sided PCBs for through-hole and surface mount designs with track densities of 40-50 tracks per inch and 0.5mm SMD pitches.
Artwork generation When defining pad and line shapes, the following minimum sizes are recommended for reliable results: Media. How To Make a Concrete Volume Knob. MT 100.
Online Circuit Simulator with SPICE. How to make a printed circuit board (PCB) using the UV light LED method. This instructable shows how to create well done PCB's using Ultraviolet light.
It took us about 40 boards before we perfected our PCB, so we will share what worked and what didn't work. All the supplies can be bought from Fry's Electronics, Ace Hardware, Goodwill, Radio Shack, and Ebay . Our PCB tested the Atmel 208 pin PQFP Integrated Circuit (it may not look like it from the poor image quality but there were no shorts between all 208 pins! ). The materials needed are as follows.
PCB: -Transparencies (MG chemicals brand ) -UV Presensitized Copper Clad Boards (MG chemicals brand ) -Laser printer (Brother HL-2070N) -200 UV LEDs (Bought from Ebay - Asia Engineer, seller giorgio11185. 5mm size, 3.4~3.8 forward voltage, forward current 20 mA, wavelength (nm) 395-400-405, view angle about 25 degrees.) -200 470 ohm resistors (included with Asia Engineer LEDs bought on ebay. Tools: -Soldering Iron (any soldering iron will do, I used ) -Solder (We originally bought Lead free solder. PCBs for DIY audio.

A Framework For Making Affordable & Stylish Modular Controllers (USB to MIDI, HID, or Serial) I have designed a framework for making affordable and stylish modular controllers.
You can use the content of this Instructable to make a wide range of controllers for a wide range of applications relevant to artists, DJs, VJs, gamers, producers, and the like. The DJ controllers I showcase in this document serve only as examples of (more conventional) interfaces you can create within the framework. I focused on making this project affordable, stylish, and most important, builder friendly. The controllers can be re-programmed to send serial, MIDI, or HID messages.
The modular design allows you to plug the controllers into one another, thus requiring only one USB port on your computer. More info here. Some hype at engadget. **Remember to read this entire Instructable before beginning any of the constituent steps**
