ICase, the charging pencil case that you will never loose!

In this instructable (my first) I will show you how to create a clever pencil case of your own, it is simple and easy to make, I decided to make it because of two problems that i have on a regular basis, my phone going flat with no where to charge it and never being able to find my pencil case, to combat this I searched instructables to find ways to charge my phone on the move, i found a great instructable called minty boost that is a clever emergancy device for your gadgets, I thought that was perfect but then realised that I would probably forget to take it to school and then be in the same position I was at the beginning, so I wondered what I always took t school, and decided on my pencil case, I decided to adjust the design of the minty boost project to fit well in a pencil case, but realised that I am always loosing my pencil case and so that put me back at square one,  I then found key finders, that you atach to yoor keyring and when you press a button the beep and light up, with sme adjustment I thought that would be great, a charging pencil case that you can never loose!

Step 1: Time to build it

Ok so lets start the build
You will need

A mintyboost kit (you can make on yourself like me but it is not cost effective or as neat)

2X single battery holdershttp://www.ebay.co.uk/itm/1-2-3-4-6-8-x-AA-AAA-23A-9V-Battery-Holder-Snap-On-Connector-Enclosed-Box-Switch-/180814661762?pt=UK_BOI_Electrical_Components_Supplies_ET&var=&hash=item2a1964c882

A remote controlled key finder, you can buy whistle ones which are cheaper but I think this is the best I can find

A pencil case of your choice, make sure it will fit a small circuit board and two AA batteries in a line, also it must be easily sewn into, like neoprene fr example

some material that matches your pencil case and a needle and thread that also matches your case

You will also need a soldering iron and some spare wire

great update on the minty boost! can you charge an ipod completely off this thing?

[ellwoodjoe]

If you use the minty boost then you should get 1 and a half charges off it, i copied this off of his page :)

iPod video (tested, using alkaline batteries): 3hrs more video (1 full recharge)
iPod mini (tested w/rechargeables): 25 hours more (1.5 full recharges)
iPod shuffle (unverified): 60 hours more (5 full recharges) thanks for the comment!
