This month, Shawn Blaszak, at Pumping Station: One, shows how to convert a standard TV remote control to solar power. Leave your remote sitting on a sunny windowsill and let it top off the charge in your batteries while you are away from the TV. [via]

Ever wondered about how a Voltaic solar panel is constructed? Here’s a short video showing the the composition of the panel and why its so strong. [via]

With the Solar TV Remote project from MAKE Volume 25, you’ll never have to replace your remote control’s batteries again. Instead, just leave it in the sun to charge up! This project is fairly easy and you may already have most of the tools and supplies you’ll need.

MintyStick! Andrew writes:
Finally, I have succeeding in producing my own variation on the MintyBoost. I found inspiration on this post (http://forums.adafruit.com/viewtopic.php?f=15&t=18225) on the Adafruit forums. It looks like a stick of gum, and I like it, because it’s single-sided, and because it looked like it would be pretty easy to make at home with my toner transfer setup. I call it the MintStick, because sometimes I don’t like to spend a lot of time trying to come up with good names for things. It’s version 3.0 to indicate compatibility with the MintyBoost 3.0 (since it ought to support the same devices).

Today’s method of flexible solar cell manufaturing, is based on highly purified silicon compounds, which is an expensive procedure. MIT came a step closer to cheaper flexible solar cells, by using organic (carbon-containing) compounds to make lightweight, cheap and flexible cells.
The main problem why carbon did not work so far, was that graphene repels water. Typical procedures for making an electrode on the surface, by depositing the material from a solution do not work. But the MIT team added some impurities onto the surface (doping) and this changed the behavior of graphene, making it possible to bond tightly. Moreover, this doping increased the conductivity of graphene.[via]
