Ah the wonders of Firefox:

Copied the word Arduino in the URL line and.....:

I got a freeduino which is a clone of the original one, but next lot I get will be these ones..

Normal USB plug not the big printer one, and headers on a pitch that will work on a prototype board. Whoever put them where they are on the arduino needs their head read.

This one looks like a good idea, but sadly I can only find a US supplier for it so there is stupid shipping charges. Also the stupid big USB plug on it as well. http://www.ladyada.net/make/boarduino/  - could easily have the small one _and_ a dc connector on it rather then the big one.

Looks a bit overkill if you already have a computer running to manage things...

richms:

The way the computer is set up there is no feedback for stalled motor, or if its finished. Yes, the parallel port could be used as an input as well, but that still leaves you at the mercy of other software not messing with the port, it not crashing etc. With a microcontroller doing the work you can have timeouts, count motor revolutions for if its jammed, reading the microswitches to check its done in time etc etc which to me is well worth the few $

csa3d:

With that Arduino, does that handle printer port commands via usb?  Is it something you need to code yourself like a nutchip?  Is it just an interpreter of USB, therefore needing software to tell it what to do?

Back to my circuit, putting the monitor unit back in the cab broke something, or is shorting.. because it's not working properly once again..  :censored:
