Hi, i have made the system shutdown of the cd cover, i do it with two magnets and it's works properly, original spring is not strong enought to open the cover by himself, it's good.

this is looking very very good.

I am looking for li-po batteries that we can found on ebay (chinese products) but i'm a little bit afraid by this products (it seems to be dangerous ) and as you knew, i will have the system in my hands, i don't want it will explodes in my hands if you see what i mean, do you think is a good idea to purchase chinese li-po batteries?

[themadhacker]

no

[eurddrue]

no

Why not? I don't find anything wrong with generic batteries. All you would need is a decent protection circuit from batteryspace.com and you should be golden.

i edit my message, i read a lot of message on other forum of modelism, the li-po from ebay are poor quality, potentially dangerous, if you got it on your little car is not a problem if batteries become dangerous but in your hands it is another thing, i'm looking for an other solution, too dangerous for me, i will see on batteryspace.

Well, i look on batteryspace and i found that,li-on battery pack 4000mA 7.4V + charger, i have to modify the pack but i think it is a good solution.

Not a bad selection.
You should be good, but there is nothing really wrong with generic batteries. It just depends where you get them (a safe place is usually NOT ebay, but it is always worth a try.) When they are generic, usually they also have more mAh (in general) because most people want a replacement with more battery life than the existing one. Generic batteries just do not have the "safe" company logo on it, so warranties are usually much smaller (if you get one at all). As you don't need warranties anyway, it honestly doesn't really matter. And if you get a generic battery, you can usually get one with a greater capacity for a smaller price.
Oh, and almost all batteries are from China, so don't be prejudiced against the smaller generic companies. (Ok, I take that back, some are from Korea and Vietnam.)
With your current set up though, you should be OK, as long as you know what you are doing.

Also, I don't think there is a way that it would explode in your hands. It would only explode in your hands if you happened to be charging and playing at the same time.

[64M320N3]

Or if you overloaded it. (Also by charging it.)
The only way you could do either of those things, though, is to have a really crappy charging circuit, and I don't recommend that. In fact, I only get name brand charging circuits because the only generic one I ever had was incredibly poorly manufactured. I had to resolder some things, for crying out loud! And then I threw it away, because even after that it didn't work...
There is nothing wrong with the battery itself, but it all depends on what you charge it with ( or if you do a terrible job at setting up the charging circuit).

Allright, thanks for all information, only rest to choose the good product, good batteries and good circuit, no secret .

I presume you have engineered the CD pop-up holder not to open accidentally when your fingers press on it while holding the case?

[64M320N3]

I sure hope so .

[darthchris13]

the cover of the cd cannot open by accident,magnets are strong enought and I must draw strong it to open.no problemo

[64M320N3]

Sweet. Keep us posted!
That was sort of a design flaw in Ben's PSonep in his book; the magnets he suggested were too weak.

[DopestKidEva]

But for ben's psonep didnt his work off a spring not a magnet
