This Nanoscope was built during a 5 day LEGO workshop, LEGO and Makeblock allowed for some rapid building but some custom 3D printed parts were also needed. It can sense very small structures and scan them in. Via: Make and Wired “The microscope they constructed is built upon a metal base, with housings built from Lego and the various component holders 3D-printed to ensure a perfect fit between the
 So we have all seen a useless machine before and what could be more fun that one of those? How about a Double Useless Machine, this is the machine for us who might be a bit too lazy to interact with the machine. With this design you simply need to take the switch off the center mode and watch the machine in action.
This RGB LED Infinity Mirror uses an Arduino controlled RGB strip that allows some control over what color and pattern are displayed on your mirror. When off this type of mirror looks like a normal mirror but when the LEDs are on it gets reflected onto the normal mirror at the back from the one way mirror on the front. This makes for a great looking effect! “It’s an
 The prize this week is an 6V 0.6W Solar Cell. This contest will run for one week (September 22 – October 4, 2013). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please note the image above is a side view of the thing. Please do not give the answer in the comments. Send an email
 This is an interesting look into old school rectifiers. Mercury Arc Rectifier have now been replaced with solid state bridge rectifiers which are inexpensive and reliable. I wonder how many of these Mercury Arc Rectifiers are still in operation, it seems that lots of this old stuff will be kept in use until it fails. “Operation of the rectifier relies on an electrical arc discharge between electrodes in
Hobby King had a great plan to get people building big lifting copters. They call it the Beer Lift but water is used as a substitute although I am sure an equal weight of beer is weighting behind the scenes for enjoying after the competition. The last video isn’t a heavy lift but make sure you watch what happens at 2:20, that is some good flying!
 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?
