DIY Solar USB Charger - Altoids

DIY Solar USB Charger - Altoids
I've been reading a bunch of blogs this fine Earth Day morning and have noticed that most of them are posting little write ups about green solar powered USB gadget chargers. They're all quite nice, but also quite expensive. I don't think I've seen any for less than $60, and I've not seen one that really suits my style. Instructables has quite a few guides on how to make Solar USB Chargers, including the very well done guide on how to combine a Lady Ada Minty Boost circuit with a solar + lithium ion battery. Great, but a bit expensive to make and not a very simple project for the weekend DIY person. Well luckily for us I know how to make one for under $20 that is better in nearly every way and also completely fits into an Altoids Tin. *** Update: I've since retired this kit.

Solar Powered 24 Hour Greenhouse You're probably thinking to yourself "Hey, isn't EVERY greenhouse solar powered?" To which you'd be correct. The greenhouse I've created is in fact a DOUBLE solar powered greenhouse in that it uses sunlight both day and night to help plants grow. I live in Wisconsin, which is usually rather nice. Unfortunately Winter has been going full blast for months and shows no signs of letting up. For a mammal like myself this kind of weather is annoying but not overly harmful. Solar Bag You'll get "carried away" experimenting with the Solar Energy Bag! Use the Solar Bag to demonstrate concepts of energy, thermodynamics, density, and buoyancy! Take the 50-foot long, 36 inch diameter tube outdoors and fill it with air. Close the end, tether with string, and allow the sun's energy to heat the air in the bag. In a few minutes, the bag begins to float! Challenge students to explain their observations using kinetic theory and gas laws.

Creative Ideas For Making Beautiful Furniture From Upcycled Pallets Wooden pallets mainly used for storage and transport of various products.

vintage book travel-tech organizer As you may have figured out from my My Life Scoop posts, I’m a bit of a nut for tech accessories, especially pocket-sized ones. I can’t get over how awesomely small our entertainment devices are becoming; it makes traveling with them so much easier. But one issue I keep running into is how to neatly organize everything, especially the power cords and connector cables that accompany my favorite devices. Rather than spend another plane trip rummaging through my catch-all carry-on bag searching for my headphones, bumping my head on the seat in front of me every time, I decided to make a small tech-accessory organizer using elastic ribbon and an old vintage book cover. This project can be sized up or down and customized in many different ways — the best approach is to gather all the tiny tech things you travel with and see how much there is.

Autonomous Solar Robot Stage 1 Background: Hi, my name is Ben Rawstron and this is the robot I have been working on, recently in my sophomore (tenth grade) year of high school. I created this project as an "independent study" at my local school here in Waldoboro Maine since I wanted to surpass the limitations of robots I had worked with in the past. Cooking with the Sun - Creating a Solar Oven Summary Student groups are given a set of materials: cardboard, insulating materials, aluminum foil and Plexiglas, and challenged to build solar ovens. The ovens must collect and store as much of the sun's energy as possible. Students experiment with heat transfer through conduction by how well the oven is insulated and radiation by how well it absorbs solar radiation.

Camera Strap Cover in our ongoing quest to customize every object we get our hands on, we’ve tackled all sorts of random things around our home (ikea furniture, curtains, bedspreads…) so it’s about time that we finally got crafty with one of the items we spend the most time with: our camera. don’t get us wrong, we’re not ashamed if people know we use a canon, but we don’t feel the need to advertise it like we were nascar drivers. hence our desire to cover up our logo-heavy strap with something a little easier on the eyes. have fun!derek & lauren
