I will add and another three high quality pictures  ,  as proof that I had corrected my minor mistake about the 0.10mOhm ..   :)

I was actually pretty pleased when a project of mine showed up on Hack-A-Day.

And I had a real sense of accomplishment when I showed it at a local hacker space and a girl saw it and said "Wow.  Just like the one on Hack-A-Day." and I was able to correct her "No, this is the one from Hack-A-Day!

Kiriakos-Gr, have you put your decade box to good use yet? Is it really useful to have around?

I had check  all my multimeter's  about correct calibration ,
and I have it on my bench for quick tests too.

I had use low wattage resistors on it,
and I can not use it for currents over 600mA .
And so it can be used so to " match" ( find )  the resistance value for LEDs or small DC motors.

You can find the resistor that you need so to keep an computer fan silent at easy  ;)

The truth are that the resistors decade box, and the voltage calibrators,
are not items for daily use .

But with out them , you do have the feeling that something missing among your tools.

It looks that my project become more famous than expected.

I just did an search on Google about decade resistors box.
And got many pictures of my own ..  :D

Its one are posted to several other forums ... Example:
http://www.eaglecentral.ca/forums/index.php?S=7d6c909b9a628944de0853b870f2b1c8&t=msg&th=38622

 :D

Are you crazy !!  I got even in, at the Science Projects Archives  ;D

I had become part of the recorded  history , about handmade electronic designs .

I bet that even Dave , he must be proud for me.  ;)

 I think your Decade box is excellent, and has inspired me to make my own, yours look very professional, and I'll bet your really proud of your work, you should be, :-+ :-+ :-+ :-+
no one would or will tell me how to delete this account

For the less ambitious, you can easily knock up an R box with a bunch of thumbwheel switches with the R's wired on the backs of the switches. 
With BCD thumbwheel switches, you can also do a cheap capacitance box

Good job Kiriakos-GR, very good job!..........Love it.

Per Mike, here's mine (cheap & cheerful category). Range= 0.1 ohm to 99.9999999M ohms

Sir ,
     Apologies if i missed it in some discussion .Are there any schematics of this .I could not understand what " DC power " is doing in a decade box .

Hello Kiriakos-GR,

Firstly your project is beautifully designed. My hearty wishes for that. Can i check with you if we can use this Decade Resistance Box for Calibration of Insulation Testers ? Whats your suggestion ?
Thanks
Cane

Decade boxes are test instruments which use a series of resistors, capacitors, or inductors to simulate very specific electrical values. They can be quickly and easily substituted into a circuit and replace any standard value component. Their ability to be configured to nearly any resistance, capacitance, or inductance makes decade boxes a convenient way to find the optimum value for circuit operation. Highly useful for laboratory, education, or design work; decade boxes are also ideal for verifying the accuracy of test equipment prior to use as well as troubleshooting in the field or on the factory floor.

I came late to the party.

I would like to build one . 7 segment display? Or showing numbers instead using lots of knobs?
