Thank you! I made already a block diagram, do you want a upgrade of the diagram? With more details?

Paper will burst out at a temp op 200 degrees celsius, wood 250.I hope my/your electronics don`t get this hot!

I have a small stroke in the back for my adjustable power supply. And don`t forget the very small black lines on the front (these are open). But it`s a good idea!

The 12V is connected to the LTC and the USB charger is a separate unit that converts 12v to the 5v.I bought it on eBay http://www.ebay.com/itm/311783941370?_trksid=p2057...The order list, and electrical schematic has also been added to step 5, for more information.I didn’t have thetime to fully test the adjustable power supply, however I used spacers so theairflow can pass nicely, if it is necessary i wil increase my heat sink.

Yes i`m student and don`t have many money for it!Thankyou: Elooi, Gadget93 and Kamhagh for saying that! Actually it cost me les then +-$35 I bought anold server and sell some part form it to make the bill draw. I left with 2 PSU anda lot off other cool stuff!
