Home security is very important if you have a family. If you can make that security powered by renewable energy then you will really have nothing to worry about, it will always be on. This project guides you through how you can build a system that doesn’t rely on the power companies. Take a look!

This project takes a unique windmill design and shows you how to generate electricity from the wind. The project is 100% DIY from top to bottom and the write-up is very in-depth. If you’re curious about wind power, take a look through this project.

If you’ve ever been curious about simple breathalyzer theory this project is for you. They used a MQ-3 alcohol gas sensor and an arduino board to build it. The write-up has the software, hardware and a video of the working project in action.

Using off the shelf parts and a standard PIC microcontroller here’s a weather station that you can access remotely. The PIC takes care of all the data acquisition and serial transmission. Hardware schematics & software are included in the project write-up. Take a look!

This project is probably more novelty than useful, but its simplicity will get you familiar with digital thermometers. A pic is used to interpret output data and a gigantic LCD display is used to show it to us humans. Software and hardware schematics are there just for you!

We previously covered the Zephyr Solar Powered UAV on PyroElectro and it’s back already. Just this sunday the UAV flew nonstop for 83 hours and 37 minutes. It used rechargeable batteries for flight during the night. Both articles are linked below.

This is probably one of the more interesting projects I’ve seen in a while, at least conceptually. A solar powered UAV seems at some level a no-brainer especially if it could fly high enough over the clouds & fast enough to always be in sun-light. The engineering behind it however is very complex. The project website has all the details you’d ever want!

The drive for renewable energy sources has been a heated issue lately. Here is a wind turbine project write-up that details out the process of using wind for generating electricity. The write-up is thorough and concise (but could use a few more pictures of the build process).

This project is a very basic battery charger using solar energy to do it! The best thing about it is that it uses standard house-hold parts and the design is easy to put together.
