Portable Dreamcast need a little help

Endtime · Post by **Endtime** » Sat Apr 14, 2007 9:06 am

ok so i have been wanting to do this for some time and i just need a little help from anyone that has done this before or knows any good info the two main things i need help with is hooking up a 5" LCD moniter with speaker ( also if you know a good LCD i would like to know, dont got one yet). also i would like to know if i could use a laptop battery i have or would i have to build a battery pack on top of that how would i go about building a battery pack and hooking the battery up to the Dreamcast.

so if any one has any info it would be a big help.

Use an old PsOne screen. Just do a search for psone screen hack you should find it soon enough. As far as I know only one portable has been made and it sure was not by me. Look around here for info on it if you can I rember him posting about it here. Good luck.

that guy had a website, portablesystems.net where he made a lot of portable things like an xbox somehow. but it seems the site is down.

Why the PS Dpad and stick were used are beyond me.

If you're not gonna use the DC one because you don't like it, or whatever atleast use a GOOD Dpad replacement.

well if you have been inside of a DC controller you would know that the dpad is huge, and the analog stick is pretty large as well when you compare them to the ps dpad and stick. i think it wouldve been kinda hard to fit them inside, or it would just make the thing a bit thicker and harder to hold.

also it isnt fake, he used to sell them for i think $400 but he would only take like 3 orders cause they take a while to make and a lot of other systems he had orders for.

so i have looked inside the DC controler any one know a link or something that could show me how to make a controler for the dreamcast? because i want to be able to spread the controls out on seperate sides of the screen.

also the thing i am having most trouble finding is how to battery power the DC. Has anyone done it, if so how did you go about doing it?

the guy who made the portable dreamcast powered it with some rechargable batteries that were 50-60 dollars i believe.

ok i found some plans but i am no tech wiz so could someone make heads or tials of any one them

(i can understand some of it i just need clearification

)

at the web site there is three different setups and i dont know much of electricty and voltage in place of the 4.8v cell battery could i place a 3.7?

quite simple, the mini itx board converts a battery voltage to +12 +5 -5 -12 and 3,3V, just ignore the 5V stb and -12V -5V and wire 12 5 and 3,3V to the dreamcast.

What 4,8V cell battery ?

What 4,8V cell battery ?

one of the plans on the web site i gave had a a 4.8V cell phone battery in it and i was wondering if i could use a 3.7V lithum ion battwey it has 1000mAh just wondering if it was the voltage that was needed or the 1000mAh

semicolo · Post by **semicolo** » Tue Apr 17, 2007 11:26 am

no you can't without a dc-dc converter, the dreamcast will work at 4,8V because it's close enough of 5V but it won't work for 3,7V.
And you better use a single battery and a converter that gives you the 3 needed voltages.

it seems they feed 5V where 3,3V is needed, whil this may work, it's prone to overheating and failure.

would it work if one was to do this? can u guys understand that?

3,3V 5v 12V
{GND 2x}[1,5+][1,5+][1,5+]^[1,5+]^ ---------- {GND}[12V+]^

btw nimh AA's are like 1.4 full charge and 1.1-1.2 dead so not sure is saying 1.5V is accurate with nimh

^=like wire, or whatever, to pin

cunje · Post by **cunje** » Tue Apr 17, 2007 5:59 pm

also would about 13 volts work on the 12 volt pin?

off the battery topic lol (for now) >.> i am in need of a PSone lcd please help me if anyone knows a place i can get a new or used one for a good price or if you have one to sell and or >.> give me

don't know if it would work, you'd really better use a regulator from a single battery than what you suggest (a pack will likely drain out before the others and it'll be difficult to keep each battery to it's nominal charge, and it's not garanteed to work well).
But you can try it.

was thinking of doing the 5v voltage regulator off the 12V so 12v in the 12v pin, 5v in teh 5v pin, and then just aa's in the 3,3v. how much of the power is drained via 3,3?
