Interesting homemade windmill

This looks like a good project for kids.  Most of the materials are pretty cheap (pvc pipe, old CD, motor from a VCR).  Not so sure I would have picked a model airplane propeller thought, maybe build your own? http://www.instructables.com/id/Simple-Backyard-Wind-Turbine/

Build a remote bottle boat

Not the best of write-ups on how the author built the boat.  And its not as cheap as it could be (using an arduino for the controller, full UNO board).  But still a good learning project.  I wish the author … Continue reading

Build your own saltwater flashlight

I never thought about using salt water for powering LED’s.  Good idea.  The author took pennies, aluminum foil, tissue paper, and later on a Joule Thief.  Nice build. http://www.instructables.com/id/Water-Powered-Flashlight-v2/

Make an LED light clock

This more caught my eye as a good arduino project.  The author made a clock that shows time based on lighting LED’s, the pic is not a good example, but the video on the site is. http://www.instructables.com/id/Charliexplexed-LED-Clock-Arduino/

Build a plotter from printer/scanner parts

Seen this a few times in the past, but not this clean looking.  The author basically used CNC to make a plotter.  I like the use of the pencil for drawing.  This would be a good kid project. http://www.instructables.com/id/cheap-nice-and-weird-A4-graph-plotter-25-some-scra/

Use your CNC to make your own keys

Why pay $2 and up for a spare key when you can make your own with your CNC.  Well if you already have a CNC that is. The directions are not the greatest on how to do this, but you … Continue reading
