ABCinc's first portable
Moderator:Moderators
i was wondering if external batteries are an option, because the two batteries i purchased can only be charged one at a time, and i don't have the knowledge to find a charger to charge both at the same time in series or parallel. Then i could just get a plug at the bottom of the portable, so i could choose which batteries i wanted to use. Or if i wanted to run it off of wall power. If it draws about 450 MaH, do i need an adapter that needs to be exactly that or greater? PS, i'm going to get that voltage regulator argelfraster suggested when i get some money.

Re: ABCinc's first portable
All batteries are meant to charge one at a time, unless you connect them and charge them together
Tell me the info of the batteries and I'll help you with this.

they're Li-ion batteries for a CR-V3 camera, they're 3.3V, 2,000 mAh. The charger charges one at 4.2V, 600 mA.

Re: ABCinc's first portable
Oh I see your problem here.
You may need to use different batteries if you want them to be internal.
Otherwise do what LOB did on one of his first portables where the batteries are both external and can be removed easily for charging and plugged back in for playing.

Re: ABCinc's first portable
that's what i meant, but how would i charge them both at the same time? could i get a different charger that was meant to charge two and charge them in series that way? if so, would something like this work?

Re: ABCinc's first portable
If both these batteries are in AA form then yes I suppose.
I wouldn't trust it though.
Getting new batteries would be the best choice.

Re: ABCinc's first portable
ok, i'm getting new batteries, should i get some that use a step up regulator or get some that would use the regulator argelfraster posted? Pros, VS Cons. Price is also a big issue.

Re: ABCinc's first portable
Would something like this work for replacing the batteries, and run it off of wall power?

Edit: I'm just going to use the adapter that came with the retro duo, and not have to buy anything else.

Re: ABCinc's first portable
Question: what type of wire should i use to relocate the card slot? Would 30 AWG work?

Re: ABCinc's first portable
30 AWG it about the smallest you should go. If you're not an experienced solderer, go for something a little bigger.ABCinc wrote:Question: what type of wire should i use to relocate the card slot? Would 30 AWG work?
Re: ABCinc's first portable
I went with the 30 AWG, and it works really nicely. but before i was using 22 AWG, that was a big screw up.
Anyway, the cartage slot is half way done. pics will be uploaded soon.

Re: ABCinc's first portable
i think i pulled two pins, i'm not sure. If i did, at least i have an original super Nintendo that is useless that i could scavenge for parts.
i think i pulled about the 11th from the right on both sides.
Edit: desoldered the cartage slot off of my original Super Nintendo, and is half re soldered, but i ran out of solder. Hopefully i can get some $$$ soon. I've also decided to put the controls on the case and i'm going to have a joystick instead of a D pad. Hopefully it turns out.

Re: ABCinc's first portable
OK, Monday i finished soldering the card slot, and today i wired up the power to everything. When i power it on, the screen and the retro duo boots up, but there is no video or sound. The whole board is getting power, the fuse is still good, So i don't know whats wrong. Any ideas?

Re: ABCinc's first portable
not to sound rude, but just to make sure you checked everything - is the cart in the correct way...? i know it can be an easy mistake to make.
edit: wait, i just noticed you soldered the cart slot to the bottom of the duo board. did you wire them properly...? they may be in reverse, which would result in nothing happening.
