Codeman - So what your saying is if your portable ran off 2 AA batteries, (Magically) then you could add more batteries in series to get longer playing time?

Hammertime - Can't wait to see how your N64 portable comes out. It will probably look a whole lot better than my PS1p.

Milligram is abbreviated mg. Megagram is Mg.

How much current would the AC plug have to put out to charge 2 3600mAh NiMH batteries in parallel and run the N64p at the same time?

Do you have to have a fan?

I might just go with no batteries like bacteria, the whole prospect of using batteries is adding close to $50.

Would I need seperate psu's for the LCD and N64? Or, can I use one? If so, what voltage and what current?

All the info is in the stickies and in guides. Check out the diagrams on portables of doom.

hammertime94 - Yes, I decided against adding batteries for the following reasons:

1) Cost of buying decent batteries, light and powerful.
2) Added weight - not unsubstancial - the weight of an N64 portable (N64 mobo, controller, PSone screen and mobo, cart, etc is a reasonable amount as it is
3) Batteries are a hassle - knowing how much playtime is left before recharge, etc
4) Unless you are playing outside, you are always near a mains power source.
5) Saves other issues.
6) My system works with the car adapter. I finally got the TI board to work, but am reluctant to use it in the mod as I have read that they aren't as reliable as they are made out to be and sometimes can damage your system. I don't know if this is true or not, but can't take the risk of the TI board failing and frying my system. The car adapter works fine - although prohibits the use of batteries.

Fan - Up to you. The unmodded N64 gets quite warm, and has plenty of air spaces in it. If you are playing your N64 system for a while, hold the case and see how warm it is. If you are housing your system in a smaller case with less airgaps, the system can only get warmer. If the system gets something like 50-60 degrees it can melt your case; under that it might make your plastic case a bit mushy. If you don't mind a warm system and make your case out of wood, you might be ok; although a warmer system will also make your system die quicker.

Why risk it? If you use heatsinks and a fan to get the warm/hot air from the case, make your system airtight, with airholes in and out; your system will stay cool. Whether you use a fan to suck air in our suck air out is up to you. Personally, I went for an air exhaust (air sucked out).

The larger the fan, the quieter it is generally. 50mm or 60mm are ideal. If you want a really small fan (c. 40mm) you might like to experiment with a fan from an old graphics card you might have lying about - about 6mm high, generally quieter and less high than separate ones of this size you might buy. Master of Portables - if you read this post, you might consider this alternative to the one you recently bought, as your case is so small so space is so crucial, this might save you some height.

Something like this? 60mm 8dB 10CFM. I mean how much air do you need to suck out? Is 10CFM enough?

Too fat, 25mm thick is thick. Apart from that, you have to mount it (it is an open fan), but it is quiet and yes, airflow from it is fine.

On my thread you may have noticed a pic of the fan I am using, it is about 6mm thick and easy to mount as it is an air exhaust, and is quite quiet. It only cost Â£4.99 from Maplin (I live in the UK).

I just bought a N64 from ebay. I'll order all of my other parts from mouser and ebay later, and I'll order everything for the case sometime later on after I am finished (or close) with the guts. I don't like to count my chickens before they hatch

.

Which of these would be better: Zalman or Thermaltake?

Is a 40mm x 40mm x 10mm or 50mm x 50mm x 10mm fan good enough?

Double posting because I think no one's even looking at it because I only edited my post and maybe it doesn't say there's a new post when you do that.

Yes, finish getting the system fully working before you think about a case.

It doesn't matter which brand of heatsink you use, you want them fairly flat and big enough to completely cover each of the chips. Mine were Thermaltake; only because I got them from e-bay and they looked ok.

Yes, those fans are fine. If it doesn't matter which, choose the quieter one. Consider though how you will mount them and get airflow...

My n64 came in, but I don't have any cables so you'll have to wait for pics.

Today, I was very bored and I made a Sketchup model of my proof of concept because the paint drawing was getting on my nerves. Ignore the dimensions.

Here's a top view pic:

Is that to scale, or is that just where all of the buttons will go?

Post by **Skyone** » Thu Sep 13, 2007 9:19 pm

Hopefully just where the buttons go; Brightness/Volume buttons are as big as the A/B buttons.

Looks very nice though.

Put 'z' on the same side as 'l' otherwize its going to be dificult to play some games.

It's not to scale.

I have started cartridge slot relocation, I'll post a pic hen I am finished. What's the extra cartridge slot on the bottom for? I looked it up and found something about 64DD, I'm guessing the DD is disk Drive. Is this true or am I just confusing myself?

It was meant for expansion hardware, like hard disk system; however it was a failure. Not needed, remove it, just pry it off. You can then just lift off the cart slot (see my guide for more details).
