Disecting the hip screen

Post by **Sparkfist** » Sun Oct 24, 2004 7:02 pm

I was going to see about pry the screen away from the controller sometime this week. I wanted to ask if I removed the 7808 power regulator an conect the power and ground to the board directly? I'll be using a 9.6v battery you think I will run into any problems?

Good luck with this. I bought the Hip screen thinking it might have potential in the portablization arena. From what I understand, it runs on 12v, right? Or does some of that get disipated by the 7808? I'm very curious about this because the quality on that tiny screen is actually quite remarkable for the price. Good luck again.

Well I know that the 7808 regulator works as the case around the screen gets rather warm. I remembered Gannon saying it will run on 8v if you remove the 7808, I just want to be sure.

so you're gonna put 9.6v into the 8v line......hmmm I dunno if that's the best idea......

Well I've seen the chart on doomportables sy you can put up to 36v into the PSOne so, I'm not intirely sure, but an added 1.6v cant really do that mcuh harm right? Besides my only other option is run 12v to the 7808 regulator, and as much fun as that is I'm looking to use it on my PSOne or Atari and they dont nned that much juice.

you can put 9.6v into the screen but only if you don't remove the 7808. otherwise you would have to find something to convert that 9.6v into 8v.

I'd say try and find a ldo 8V converter, that'd be pretty safe.

LOL, Im on digikey looking for one right now.

Well do the sell LDO at RadioShack? Asking as it will be much easier, I dont want to pay shipping for one thing I can buy down the street.

yeah, I doubt they'll have ldo 8V regulators at radio shack, or even 7808 regulators for that matter. THe only ones I've ever seen at radio shack are the 7805, 7812, and the adj. regulator.

yeah for electronic components such as 78xx regulators and ldo regulators Radioshack simply sucks. They always have the same parts and there aren't very many. like gannon, the only voltage regulators I've seen there are the 7805, 7812, and the adj. regulator. good thing there's digikey.........

www.mouser.com is good too. But I get the digikey catalog.

I like how on www.digikey.com if you type in the search something like DC-DC converters it'll have another thing where you pick the Vin and Vout, amps, type of DC-DC converter, stuff like that, and then it shows what DC-DC converters match the one you need. It makes it real easy to find just what you need.

I like that too!

Yeah, it's a lot easier to find parts like that on digikey than on mouser
