Drink a lot of beer in the bottles and have too much recycling every week?

Don’t worry, you can turn your empty beer bottles into powerful solar-powered LED beer lanterns that will light up your house at night for free.

Al Gore and company have helped us to see that our planet is in peril. Lend a hand, make a toast, and help illuminate ways for saving Earth — all at the same time! It’s easy to do your part: recycle, refill, and recharge. Just take your fave beverage bottle (keep the cap), drop in a flexible solar panel, a step-up switching regulator circuit, a rechargeable battery pack, and a powerful LED, cap it, and you’ll have a self-sufficient garden lantern that is ideal for shedding some light on solving environmental issues. You will have to choose your bottle carefully, though. Clear glass rules. Also, wide-mouth bottles are easier to convert than narrow opening long-neckers. Like your grandfather who built ships in discarded bottles, put a modern spin on bottle building while being conscientious of your world. Cheers!

Here’s a cool set of DIY colo-changing LED coasters.  Basically, it runs on solar power, LEDs light up in red for hot drinks and blue for cold drinks.

Looks pretty simple to make, maybe a good idea for your next circuits projects.

Smart Coasters are cast-plastic coasters for your drink that light up red when you put a hot drink on top and light up blue with a cold drink. The design is fully analog– no microcontrollers and no programming– and they incorporate a solar cell so that the whole thing is hermetically sealed: waterproof and washable. Complete step-by-step DIY instructions are included for both the electronics and the resin casting.
