 I find it interesting to see how inexpensive electronics are constructed. My daughter got this Motion Activated Wrist Light at a school event. All of the kids were wearing them so that every time they clapped in rhythm the entire arena was flashing with a pulse of light. She no longer wanted it so I thought it would be interesting to see what made this simple thing work.
Are you looking for a project that will let you take control of the lighting around you? Look no further than the Glo Control. “Glow Control is an Android app that couples to an Arduino-based controller over Bluetooth allowing for control of various tasks including Landscape / Patio LED lights. Â You can either schedule the zones to turn on / off within a time range, or use a light
Instead of a lawn tractor this Robot Tractor might be just the thing you need around the yard. It might need a bit of weight added to the design to allow it to pull anything substantial but that shouldn’t be an issue. I an see it being a great help to landscapers needing to pull around carts of material such as mulch, sod, hand tools, etc. If there are
Not that this is going to be replacing a real CNC machine any time soon but this LEGO CNC Lathe shows the cool capabilities of the LEGO system. It sure is nothing like the LEGO that I grew up with that had an optional motor and wheels to allow your creations to move about.
 If you are looking to jazz up your look this Halloween why not add some lighting effects to your face! Adafruit has a great tutorial on how to use their GEMMA microcontroller to make it happen. The tiny GEMMA is using a Attiny85 and is programmed using Arduino, it looks to be a great platform when you don’t need much power and only a few IO pins.
 Who would have thought that we would see a $200 printer this early! Looks like the MakiBOX by Jonathan Buford is currently the cheapest 3D printer around (please correct me in the comments if there is something cheaper). Now that Makerbot has gone through some drastic changes and is no longer open source are we going to see lots of low cost entry level machines fill the void?
 Who knew you could use the guts of a power transistor as a solar cell! Steven fromRimStar even takes it a step further and chains five 2n3055 in a base to collector configuration to generate enough voltage to power a small calculator. Funny how some electronics form China are working fakes. The small calculator he got has a small solar cell in it already but once the case
