The best way to spend money in this endless summer season would be in buying an environmental friendly solar charger for each and every gadget of yours. But wait one need not to buy it according to Joshua Zimmerman from Instructables. One can get it without spending money. Well this sounds very interesting because getting a solar charger for free is not a bad thing because it would definitely save money which could be used for other purposes.
Zimmerman has suggested DIY USB charger based on solar energy which also very comfortably fits inside the Altoid tin. With this new solar charger one would be able to charge up most of the mobile devices by means of 2 AA rechargeable batteries in addition to agile thin coating solar panels. So one can see that a solar charger could be created by oneself that serves to save a lot of money of the user and the best thing about it is that it is also very easy to construct and not difficult at all. Given are a few steps that could be followed to create your own-
First of all assemble the list of things that one needs to have. On would require thin coat of solar panels, a pre-assembled USB based charging circuit, 2 batteries named NiMH AA, a battery holder and a diode along with wire and definitely Altoids Tin. Assembling these things would not be just enough and one must also be prepared with a wide range of tools with him. Get prepared with a tool kit including soldering iron, hot glue, electrical tape, tin snips along with wire cutters. So, all these are the things that one should have with him and then he can begin his work. This electronics project is a simple and small one only and should be completed within a period of 1-2 hours only. So, it is an idealized starting project for all.
Joshua Zimmerman has provided a full guide that could be used for the development of solar charger. The cost comes out to be only $30 against the industrial charger that costs $140.
