Tear down of cheap Amazon decade resistor box

<< < (3/5) > >>

JimKnopf:
Bad design, bad manufacturing, cheap 5% resistors.

RNA:
haha that's the same style as in my original video i posted.  I wonder how many of this useless design they have made?  They are all over Shamazon. 

RNA:
oooh things are coming together now

RNA:
I am pretty pleased with how this turned out!!  I will make more videos when i can.

Very nice job!

I much prefer rotary switches to the slide switch designs.

Nuts & Volts has a good article about building both resistor and capacitor decade boxes here: https://www.nutsvolts.com/magazine/article/September2016_Capacitor-Resistor-Substitution-Boxes

Often you can find good quality switches at surplus electronic suppliers that are much cheaper than Digikey etc.
