That looks like a nice setup. All those through-hole components,
though, make me shudder almost as much as the original electronics! ;)
I dunno...it doesn't look all that bad, and through-hole makes assembly
easier for most people. ;P
Yuck.
Yep. The
electronics are frightening. The rest of it is
respectable, though.
THIS can solve all your problems in a simple way, and you can do this
board at home.

This is the board all of us use here, and works flawlessly. The main thing I would have done differently with the
board
design/routing would be to avoid turning resistors and jumper wires at
odd angles and widen the lead spacing for the resistors where it is
-really- small. Some of those resistors' leads are just bent way too
close to the resistor bodies which can cause stress cracking inside the
resistor when forming the leads. I'm sure there'd be other things I'd
tinker with if I were editing the board design, but those two things
jumped right out at me when I first glanced at the photo.
The whole electronics package is just a mess.
The Phoenix Contact plugs for the motors are a really
nice touch though.
Those are way better than having to disconnect 4 screw terminals each
just to disconnect a motor.
I like those a lot. I use them a lot at work.
