Need help with touchscreen

Pages: (1/3) > >>

Turnarcades:

I've already completed 1 touch-screen project but the other day I bought an ex-POS for the bargain price of £20 delivered. It's a Casio QT-8000 unit, which is essentially a tablet PC as the 1.2Ghz PC is integrated into the rear of the 15" touch-screen monitor. However, I took a chance as it came without any cables so am after a power lead for this unit. From online documentation I've discovered it's got a 110v power supply and requires a 19v power adapter. Simple enough yes, but I'm having difficulty finding one as it has an unusual power jack:




It's a great unit and I'm hoping I can get it up and running. It supports XP and was working when last tested by the seller so hopefully it will work out to be a great bargain. So, does anyone know where I can get an appropriate substitute power adapter in the UK or will ship to the UK?

Can you open the unit up to see where the terminals go to? You may be able to wire directly to the back of the jack from a suitable PSU if you can't find the correct male jack.

I guess you will need a 230v PSU rated at 19v, if you found an original 110v PSU I guess you would need a stepdown unless it takes 110-230v. My touchscreen needs 60w, do you know what yours requires?

I'm not too hot with electronics so take everything above with a pinch of salt, or even better get an answer from someone who knows what they are on about.  :)

I just thought I would add my £0.02 in case it helps.

I had to buy one similar to that for my Elo touchscreen.  Hard to tell from the picture, but is it like this?

I found those on ebay from this Google search results page (200 more hits):

Good luck!

Thanks guys. I would do that Franco but when it comes to wiring I don't like dicking around with power supplies and the like, so a hack is out the question this time round.

Enskpo - that's exactly the type I was looking for. After doing a search on ebay uk with your parameters I've found plenty of suppliers who do this, so I will pick one up from there.

Franco B:

Ah, nice. That was an easy solution :)
