Many?
Considering how many I ordered, I'm scraping the bottom :)

I see. I didn't recall how many had been produced.

Glad to see this come back to life.  I enjoyed getting and building mine.

Same here a very useful tool with 2 short EZ hook leads.

Fortran did you ever do a Capacitor version?  I remember some suggestions were made at the time.

I purchased one of these:

https://www.ebay.com/itm/Resistance-Capacitance-Decade-Substitution-Box-w-RC-Network-Switch/322859615512?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D49102%26meid%3Dc8b9f38a01d04033b8f4d94757f5de62%26pid%3D100675%26rk%3D2%26rkt%3D15%26sd%3D362147931643&_trksid=p2481888.c100675.m4236&_trkparms=pageci%253A19991558-c1ba-11e7-94e7-74dbd18055b7%257Cparentrq%253A896be14c15f0a990a344d23afffe09c9%257Ciid%253A1

(1% resistance/5-10% capacitance) and use it all the time.  To me, the ability to quickly test and cycle through different RC networks was worth the cost (I have one I built myself with through hole parts that this replaced).  I'm sure someone could easily combine the two into their own design with available boards.  I'd love to see a higher tolerance model (0.1% resistance/ 1% capacitance) available or maybe this becomes a weekend project to desolder/resolder higher tolerance components in.

Even better would be a version with inductance as well to make RLC circuits.   I realize the serial/parallel complexity increases but I would jump on one if it was available or even build one if it was available in kit form.

Hey, a guy can dream, right?

I have went ahead and bought 10 kits. 
Then I tried to find matching switches quickly on Farnell - there were none. 
So I ordered 10 sets of 10 switches that looked suitable from eBay. 
They took a month to arrive and turned out to be of wrong size.
By that time I have lost interest and just bought a decade box from Farnell.
In the end everyone's a winner.

Well you wouldn't have needed to look through more then a few pages of the thread to find what switches it uses.
Or just asked :)

It's the KM2.

It was really a fleeting "there and then" project for me.  I have ordered more.

P.S. Are you IV or 77?

I'd like to order 12 boards only. How much including shipping to the USA?

6 PCB's = 1.50 USD
1% resistor kit = 2 USD
Shipping worldwide  = 3 USD

Payment via PayPal to [email protected]
Send me a PM with correctly formatted address.

So 6 USD.

Great  :-+
I'll ship tomorrow. It's a bit late at the moment.
