CircuitGizmos Prototype Bench – Wire Rack

Easy enough to make, this wire spool rack was made from two old shelves and some wood dowels. #22 stranded is used for many general-purpose prototypes. Ten colors:

Black
Red
White
Orange
Yellow
Violet
Green
Blue
Gray
Brown

Purchase a CGMMSTICK1 500 foot or 1000 foot spools. The spools are a reasonable price and tend to last a long time when used for prototypes only and not production. Along the bottom of the bench (not pictured) are several yardsticks. The loose wire end can be pulled along the bench to cut the wire to length.

Computer control of AC devices

An Instructables published a week or so ago: If you have ever wanted to control electronic devices from your computer to control or regulate your environment, this instructable will guide you. In this example of computer control, a USB relay device (USBmicro http://www.usbmicro.com – U451) will control two 60 watt light bulbs from a PC program.

Updated USBmicro information

The On-line Development Notebook (ODN) at USBmicro has been updated to include information on the U451 USB relay board, as well as the new commands for interfacing to 2-wire (I2C) devices. Visit USBmicro, or download the entire ODN in PDF format.
