Yay I’m done with another small kit. This one is a nice battery-powered USB charger. You can plug in anything that charges over USB like iPods, cameras, cell phones, etc. to get a lot more run-time. It runs off of 2 AA batteries, alkaline or rechargeables and has 2.5x more juice than a 9V-powered design.
iPod video (tested, using alkaline batteries): 3hrs more video (1 full recharge)
iPod shuffle (unverified): 60 hours more (5 full recharges)
iPod mini (unverified): 26 hours more (1.5 full recharges)
This project is suitable for beginners, some soldering tools are necessary but even if you’ve never soldered before it should be pretty easy. You can etch a circuitboard and/or breadboard this up, or simply buy a kit.
I also spent a bunch of time documenting the process by which kits are born, so that people can learn about how to design stuff like this.
Thanks to EYEBEAM Openlab for supporting this project as part of my fellowship!
