Started Design of 901 PCC for manual batteries.

[vapordragon]

I am a major in electronics engineering and figured I would try my hand at creating a PCC when I couldn't find one for the 901 that could charge manual batteries. The idea is to build the thing with one of two options. I am thinking of making the case itself charge via induction and I have the formula somewhere to figure out how to step up/down the amount of voltage/current transfered across by the induction. If this proves to be too difficult then I will be making the case with it's own charging cradle that you just drop it into. If anyone has ever tried something similar please let me know. I would greatly appreciate any info that anybody may find useful to the project.

Sounds cool Vapordragon, Ralph did something similar a while back -

Here is my latest pass through mod. I really don't like the wire so modifed it to a charging stand - when I put it on the stand it charges and I can pick it up without a dangling wire. I made it today in a few hours out of brass sheet and tube. It has a touch switch so there is nothing mechanical to wear out.
This is the stand:

The box shaped PV is made from a sheet of brass - it still needs a cover:

Here it is sitting on its stand:

Good luck, let us know how things work out

Sounds like a nice little project, but wouldn't it be a bit pricey using an induction charger? Good luck with it though, let us know how it works out.
Just for info, the KR808D PCC will charge manual 901 batts.

No it would not be very pricey as I plan on wrapping the cores myself using non conducting ferite cores and different AWG size coated magnet wire. Could be as simple as iron window screen plastic and wire wrapped around it. Maybe you know this and maybe you don't but so called "induction" mats are just very old technology given a new twist. All transformers use induction to step up/down the current/voltage. All they have done recently is take what was once inside one big case and put a piece inside two different cases that when brought together does what a transformer has always done. It's actually really simple and companies just charge a buncha money for it because most people nowadays don't know and don't care to know how something works. It's a cool new toy and thats all that matters. Oh and thanks for the info on the PCC. I will look for one and give it a shot.

Holy Green Cow Batman!  I think MacGruber has it made! Great lookin piece of equipment there bud! Keep up the great work.

I have made some progress in between work and school. Still R&D but I need to study some things related to how to use high frequency induction. For now I may go buy the induction plate attachment for an IPOD and gut it to find out how it works. I may just mount those parts inside of the case. Gotta see how things go. I will let everyone know how it goes since making a charger for tornado batteries and 510 batteries would be as simple as an adaptor.
