Decade Resistor Box

I got two of these Resistance Box 0-9999.9Ω Adjustable Lab Resistor Substitution Box Precision 1W Variable Knob Switch Boxes from AliExpress, but they kind of suck a bit. The resistors are only 1/4 Watt, the precision only 5% or 10%, and I had to mod it myself to replace the terminals with banana sockets.

Today I came across Build a Pro Decade Resistor Box for Cheap! PCB & 3D Print Files Included which includes all the plans necessary to make my own resistor box and with 1 Watt resistors.

I might take this on some time.

In this video I mod a pair of resistor boxes by installing banana plug terminals in place of the lug terminals they came with and then I give a quick demo of them.

In the demo we connect them in both series and parallel and then measure their resistance with my Fluke multimeter.

I mention this video from Dave Jones on the EEVblog: EEVblog #1020 – Is A $7 LCR / Component Tester Any Good? which is where I found out about the RS-201W resistor box which he has. I searched on eBay for RS-201W but what I found for over US$1,000 (inc shipping) was way too expensive: IET Labs RS-201W Wide Range Precision Resistance Substituter.
