Previously there was a very popular Instructable on making your own “Solar MintyBoost” – before you needed to get parts from various places, now you can get them all in one spot – at the Adafruit shop!
So – if you want to make solar MintyBoost, here’s how —
Choose from either a 1W or 2W solar panel. Either will work, if you are using the smaller panel, we suggest removing R4 and replacing it with a 6.8K (or so) resistor which will keep the lipoly charger from trying to draw too much current from the panel.
Next up, you’ll need a mini-B USB cable to sacrifice. Use the one in the shop or find one in your room.
Follow the tutorial on our site for how to splice the solar panel into the USB cable.
Finally, a MintyBoost will give you a USB 5V output! Connect the other side of the JST cable from the LiPo charger into the input of the MintyBoost.
Put the panel out in the sun and watch for the charging light to go on. then when the battery is charged up, the DONE led will be lit.
You can put all this in our new Altoids mint-sized tin!
Note: While it may most devices, this will mostly likely not work consistently with the iPhone 3Gs and/or the iPhone 4. We will have a new MintyBoost and MintyBoost “rechargeable” soon, if you need to support those two devices specifically hold off until you see these new versions of our kits on our site.
