 Check out this cool 3D Printed Stepper Motor that Christopher Hawkins made. You can see in the video that it can move quite quickly and not loose any steps. This design would be idea to teach how stepper motors work. Via: Hack a Day “This is a programmable stepper motor and driver that I made out of some nails, magnet wire, neodymium magnets, a digispark microcontroller, and a 3D
Nothing DIY here other than if you win the lottery you could turn your garage into the ultimate fabrication shop using this one Mitsubishi machine. It is amazing how flexible this machine is. Programming this thing must be a blast! “The VZ20 series “Offset Head Type” 5-axis lasers provide more cutting power (2000 or 4000 watt choices), quicker response time, enhanced welding capabilities, lower cost of operation and
 The prize this week is a breadboard power supply. This contest will run for one week (April 20 – April 26, 2013). Ending time is based on central standard time.

Doesn’t look all that comfortable but this Keyboard Chair sure is unique. I am curious where all the keyboards came from? I hope they were salvaged but they were probably purchased for this sculpture. They should have completed it by mounting a right and left side of a split keyboard on each of the arm rests. The chair could then have a single keyboard USP jack and actually be
You may have seen these bubble lamps on some old ornamental items such as jukeboxes. It uses methylene chloride which boils at a low temperature. The effect shows a bubble that forms at the bottom next to the heat source and as it rises the bubble gets smaller and smaller until it simply disappears.
Jon Wise demonstrates his Raspberry Pi 3D Printer, he is using a pen in the demo but it can use an extrude to print items. The mechanical movements leek very complex when compared to a standard XY table that is controlled using 2 stepper motors. The Pi has enough number crunching ability to get the job done though. I can’t wait to see this printing a complex shape, the
 When think of what a laser cutter can do you normally think of cutting things and etching surfaces. I never would have thought of making something 3D other than making notches that can link together. This video shows a technique that holds the material being worked over the main laser cutter bed using some stilts. Cuts are made in acrylic and since acrylic bends when heated the laser
