I needed a way of charging my psp at work, I work in earthmoving equipment where 12v is not always available. So I made this up from mashing up various other instructables. Don't try this and blame me when you fry your PSP - always test the final product with a multimeter and ensure the polarity is correct before plugging in your PSP.

Step 1: Get the goods

Bits you will need......

PSP case
Two old garden solar lights (the two AA flavour)
4 AAA Nimh Batteries
5volt regulator link
Shrink tube
Spare wire
PSP Plug
It’s very surprise! I bought a brand bag from brandbagfactory.com. It is very valuable. I often purchases products from brandbagfactory.com I think it’s a good website. What you see is what you get!
Your dog ate photos on your laptop? How is that possible?
what does solder mean<br /> <br />
Seriously (no offense)? It means using a soldering iron to heat up solder (a small tube of metal) and wiring electronic components with it.
you need a switch for power to the regulator. even if it is not plugged in, the regulator will draw current.<br />
I was wondering if i can use the nokia batteries that give around 3.6v if i am not mistaken and use it directly. An added feature is that it can be recharged with a Universal Battery Charger
although quite complicated and crude Very Clever! How much would it cost in total?
pfft.. i bought solar lights at my local walmart for like 4 bucks a piece.. they are dirt cheap...
Where would you buy them in Australia?
any 'big box' store or discount store.. i am in canada so i don't know for sure
If you are using 4 re-chargeable batteries the regulator will not be needed. Total voltage of the batteries is about 4.8v. The regulator at least it wants about 7v. So without it it is better. But nice Idea!!!
smart actually... you never know when something can short and spike the power.. consider the regular an insurance poilcy or food for thought
4 batteries plus the output of the solar panels would exceed 5v well that's what I thought back when I made it.
Without any charging logic, you'd be safer using NiCad batteries for this rather than NiMH that could potentially be overcharged and destroyed.
I thought any extra power would be vented off in heat, and not a generate that much heat because of the low power output of the solar panels considering they were originally designed for AA NiCad batteries that had no charging logic.
The current of the solar cells is low enough that the NiCad's internal resistance will stop the charging process on their own. The only problem with NiCads is that if you recharge from a partial discharge often enough, they develop a "memory" and seem to run dead quicker. Just periodically run the batteries completely dead. NiMH requires more logic to avoid damage to the cells. Even most consumer battery chargers don't have enough logic. It's very easy to fry NiMH batteries by putting already charged batteries into a charger. You should always let a NiMH battery run dead before recharging.
zapping nicads with a high current like a welder will decrystalize them (thats what happens with nicads.. they crystalize and lose their potency). a welder notwithstanding, something else of high current for a split second can fix it as well.. but the NiMH arent as dangerous as you would think.. the cheap chargers will kill them though if you arent careful.. the good ones like energizer have the shut offs in them that checks them for current
i am hoping that you do not keep your psp in the case when you are charging it... that to me just spells disaster. if you are leaving a black case in the sun for long enough for it to charge your psp wont the case and what ever is in the case get really hot?
there is no more space for the psp. you just couldn't put it in :+) There will be place for some UMD's, though.
not if the air conditioner is on ;)
oh I didn't realize the cab was inclosed
Has anyone successfully done this yet? Any experience? Looks great but i would like some feedback before i try, in case i fry my psp Thanks
is it possible to use the solar w/o the battery to charge the psp while using the psp at the same time?
well, that might be possible, but the charge to play ratio wont be equal, i think the psp batterie will be depleted if you play it while charging.
what happens with the solar panels is that psp runs off the batteries but the batteries need a charger so thats what the solar panel does so the batteries have some "juice" left to run or charge or both the psp or anything that runs off of 5v
Uh... maybe it's too early for my brain to be working, but what's the point of the solar panels?
maybe it is..... maybe the solar panels recharge the batteries, read the first sentence.
I read through it, it looked like all you made was a battery pack for your PSP, hence my confusion at there being what at first glance looked like a secondary power source.
Yeah would have been better if the first lot of photos had not currupted on my CF card.
Solar panels alone do not make enough voltage to power most devices, so they are usually used to charge batteries.
