Brilliant minds needed...
Well, no "real" need for "Brilliance" per se, you just got to have a better ability with simple logic than I...
Seems, I can, with the addition of a few IC's (Integrated circuits/CHIPS), and a few other componants, (Though RS is peeing me off insisting I buy many in 25's and 50's in some cases :@) with ease, build (I'll put it simply) a unit that will allow my computer to operate 8 switches.
Now I may well have a need to send some feedback to the computer saying "That process is complete" or some such so I'll say I now have just 6 switches. Using a little binary knowledge (1's and 0's make my head explode) I'm of the opinion that with a number of and gates, I can easily convert this to 64 potential commands, 000000, 000001... through 111111, I am however desperately trying not to go too complicated on my first electronics project for some years...
What I need the brilliant minds for is...
1) I need a cheap method of stepper motor control (effectively) where all I'd need is to input Direction and force (3 force options), But this, to me, screws with my head electronicaly. The very fact that the motor input needs to be a 4 digit binary number and no more than 3 of those digits should be 1 (or ON) at the same time is screwing with my mind.
I'm damned sure this would be easily done with a shed load of logic "gates", but for the life of me, I cannot figure this one out.
ack dammit, time to trash the house further to find my soldering iron, Found my Desolder pump, just gotta find the Iron now to salvage more much needed parts from the Lexmark all in one print-scanner thingie that's already donated a stepper motor to the cause. Mebbee it'll all come to me soon.
