Bicycle dynamos have been around forever. With all the DIY smartphone bike mounts I’ve come across lately, I’m surprised I haven’t seen someone attempt combining the two until now. This is perfect for areas with sparse charging options.
Even though it’s a retail product (in select countries), this dynamo-powered smartphone charger kit from Nokia should be an inspiration to mobile makers everywhere. If you’ve come across a home brew version of this or have scraped together something yourself, do post a link in the comments. [via Afrigadget]
