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
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 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.
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.
