hehe .... yep simpler is better ... but i also like reliability and isolation of voltages

here is an updated drawing of what i currently have installed in my projector
this isolates the 5v also im using 15V instead of 12V but it works fine

Do you have a specific opto-isolator part number you would recommend for this application?

Thanks!

BUMP to announce..."2 Kits" left

EDIT- these are UNIPOLAR DRIVER CARDS

Now I found something else. These are GM-20 driver circuit cards that drive 8 GM-20 actuators. I want to sell these but most of you guys dont do beam rails so I want to list them on ebay. They are new, purchased 10+ years, never had electricity applied to them, FLAWLESS I also found a power supply to drive the cards.

Question...How much are these cards cards worth each?

I have full documentation

[Laserman532]

gm-20 kits have shipped (all but one)

BUMPED for "2 Kits" left announcement - would ship early next week.

If anyone wants the cards they are $90.00 ea. including shipping in the US. thats only $12.00 per circuit ya cant build them that cheap! Copy of documentation included.

If you throw in 8 GM20s, I'll toss you an extra $10 to make it $100.
