DIY resistor box

DIY resistor box
Resistor box is a quiet useful instrument in analog electronic based design and prototyping tasks. It can easily build with few sets of resistors and with couple of rotary switches.

This quick post is about resistor box which we construct recently using 5W wire-wound power resistors. For this resistor box we use five, single pole 12 position rotary switches and 50 wire-wound resistors. It gives 5 dials to controls 10Ω, 100Ω, 1KΩ, 10KΩ and 100KΩ steps.

Internal view and high resolution photographs of this resistor box are available at my Flickr page. Schematic of the resistor box is available in here.
