its looking great!
what tools and things do you use to make sure each componant works like it should in the sim?
machineman,
Good question. A lot depends on what you mean by "each component". If a component is say a LCD monitor... then you need a computer to drive it. ;) If you are talking electronics at a really serious level (components inside a monitor) ... a testbed of equipment would include stuff like osiloscopes and frequency analyzers and all sorts of sophisticated goodies. But for 99.999999% of the stuff...... it is FAR easier than that.
Probably 95 percent of the "components" are switches or rotary encoders. 4 percent are "off the shelf" modules that either work or don't. The last 1 percent is........

???
For that a basic multimeter unit that allows you to test AC and DC voltages, resistance, continuity, amperage, and so on is asbsolutely indespensible.
A simple 9V DC battery with a set of alligator clips attached to the + and - poles for testing certain non-computer circuits.
A simple home constructed "test light" that consists of a set of aligator clips to which you've added a red LED and a current limiting resistor.
That likely will get you most of what you need.
Add in a good soldering iron, good wire strippers, small needle nose pliers, tiny diagonal cutters, and an assortment of phillips and blade screwdrivers.
For building the rest of the wood stuff..... a circular saw, a sabre or jig saw, a good drill with a wide assortment of bits including countersink ones and hole saws, and good straightedges and measureing tapes and rulers.
If I think of more stuff... I'll post it.
best,
