Default Test load box with plugs

I've designed this test load in a project box to do away with all the fuss that I'd normally find using a test load and make things easier.
I've put this test load on a breadboard with 6 IN4004 diodes and a 1ohm resistor and connected everything up to banana sockets with extra sockets so I can test across 4 or 6 diodes.
It has 3 plugs at the front for the power connection from a regulated circuit; 1 for positive 2 for negative so I can pick between 4 or 6 diodes on the test load.
On 1 side the voltage can be checked and the other side is to check the current. The side with 3 plugs is for voltage; 1 for positive and 2 for negative, to match the power input of 4 or 6 diodes across.
The other side has 2 plugs to check the current across a 1ohm resistor.
I've made cables with banana plugs to alligator clips so that any circuit can be plugged in and a set of cables so I can plug my DMM in leaving everything handsfree.

Default Re: Test load box with plugs

That looks great, I still have just a string of diodes and a resistor that lurks somewhere in the junk on the bench, yours will be a lot easier to find and use
