This ugly thing turned out to be one of the best solar chargers i have made! It is tough and the components are protected. It charges at 5 volts 500mA which is better then most chargers offered in this market. It stays nice and cool when charging from wall power or sun.
I know what your thinking.. What is that? Why would somebody make a video of this. It’s pretty crazy looking I made this last night and i just grabbed the soldering iron and went to town.. i should have made a video but my kids were running around and making noise and the TV going and stuff so i just turned on my exhaust fan and started going to town and i didn’t really try and make something real pretty i just wanted to make something for utility what it is, is a USB charger like a lot of the things that i make theres the USB charge circuit inside here, Li-ion charge controller inside here and this is the Li-ion battery i got out of a tablet that i had a while back and one of the kids dropped it and broke it so i took the battery out. I got it all built here and soldered everything together and then i went to town with the some hot glue putting everything down everything was really exposed and i thought well id like to have everything covered so i covered everything with a i tore apart an Altoids smalls.. this is the bottom and i flipped it over and cut out some spots for the wires and then i did the same for this and cut this out. then i put it all together and i went ahead and i sprayed it silverfish paint. I put all this stuff on… a solar panel so put it out in the sun and it charges and just to make sure that you can see that the that it will charge with light.. there it is, see over top of a light theres the light now away from the light it shuts off Now of corse that light is not enough to charge it or not enough to do anything thats going to really make a difference but it’s enough to show you that when it gets light it starts pulling in some power.. anyway this was my latest creation, Frankenstein, subscribe, hit the like button, do all that stuff, thank you and leave a comment and let me know what you think
