untitled William L's Scratch Built CNC Machine Here is a scratch built machine (from the plans or book) that exhibits great workmanship, but more importantly, how some of the construction of the CNC machine was done. William L. used sound techniques to make sure the machine would be constructed as intended, knowing that some of the machine would have various size differences within the sub assemblies that would make some of the measurements within the plans not work. It is important to note that the video process for constructing a CNC machine on this site should be watched as a minimum requirement for constructing the CNC machine from the plans or the book.

Total range 0pF to 50uF. - 27th Jun 2011, Updated 25th may 2013. Another PIC based capacitance meter? The Most Incredible 3-D Printed Things We’ve Ever Seen ⚙ Co The levees have broken for 3-D printing, and the resulting deluge of printing-concepts-on-the-cheap is flowing faster than we can gather. The best of these rise to the surface for their innovating predictions of a faster/safer/healthier future. A Robotic Hand That Doesn’t Cost An Arm And A Leg Teen engineer Easton LaChappelle created his first robotic hand out of Legos, fishing wire, and surgical tubing--a feat that earned him 3rd place at the Colorado Science Fair.

DIY Air Quality Sensing from HabitatMap and Sonoma Tech DIY Air Quality Sensing from HabitatMap and Sonoma Tech tigoe — May 9th, 2013 High-precision air quality monitors are normally very expensive, but Tim Dye of Sonoma Technology is on a mission to change that. He’s been working with Michael Heimbinder and habitatmap.org to create a low-cost sensor system that when designed properly and integrated into a software platforms can provide valid data.
Alternative Print Surface I’ve always had trouble with ripping my Kapton tape. Prints are can be removed easily, without damaging the tape if the print bed cools down, but it takes so long to heat up, I hate to let it cool too much. Also, if I want to cancel a print and restart it right away with tweaked settings, I’m too impatient to cool it down first. The solution is to forget the Kapton altogether.
Mantis 9.1 CNC Mill - Make Your Bot! The Mantis 9.1 design is a radical departure from version 8 and earlier. Most notably, the part count has been almost halved! The current design has 13 parts, all of which can be made with a handsaw and a drill press. Also, I've traded away my alignment free exactly-constrained design for extra stiffness. Several unsuccessful attempts to eradicate the last of the slop in the Z axis on version 8 lead me back to the world of over-constrained parallel rods. Global Village Construction Set Definition The Global Village Construction Set (GVCS) is a modular, DIY, low-cost, high-performance platform that enables fabrication of the 50 different Industrial Machines that it takes to build a small, sustainable civilization with modern comforts. The name, GVCS, has been coined for the first time in 2008 - at a lecture at the University of Missouri, Columbia - see UM Presentation. Media Key Features GVCS Machines
How To Decrease Noise on Your Stepper Motor Driver Ahhh!!! That stepper driver’s high pitch squealing is driving me nuts! Well, it has to drive you somehow as after all it is a “driver”, right? Well, nuts should not be it. It should drive your stepper motor and be done with it. But what if by nature stepper motors are noise and it is just a matter of learning to live with it? Xantrex C35/C40/C60 Display The display shows the following: -Battery Voltage-Input Voltage (wind, solar, etc) (averaged over the last ten readings)-Amperage (averaged over the last ten readings)-Wattage (averaged)-Transistor Temperature and Duty Cycle (these two values alternate between each other)-Amp-Hour counter As far as features go: Thumbscrew to level bed from beneath (Page 1) — STL Sharing & Print Showoff — SoliForum - 3D Printing Community Trying to see a gap of 0.010 under a straight edge is not easy. When I put the straight edge from near left to far left, I can put a piece of paper under the straight edge and move it almost completely from front to back, so there are "lips" on the front and back edge. That is the only thing that I can detect using your suggestion. In particular, I cannot detect the 0.010 problems across the back. I bumped my bed temperature up from 85 to 95, and that has allowed me to get larger pieces to stick, although I believe that I am relying on the adhesion on the front, along with the structural integrity of the piece, to keep everything in place.
Cool Stools: Wood Sawdust Upcycled into Funky Furniture Anyone who has worked on anything in a wood shop knows that the sawdust goes everywhere and gets in everything, and at the end of the day all of those wood shavings and particles need to be gathered up and something has to be done with them – but what? Industrial designer Yoav Avinoam has created an incredibly low-tech do-it-yourself solution for upcycling all of this wooden excess into something simple but functional – a series of stools and a bench that require little work and even less precision to assemble. The best part, of course, is that wood shavings are normally found in workshops where the few tools required to assemble such a piece of recycled furniture are readily available – some wood glue, a few clamps, excess boards, sticks or scraps for legs and you are ready to built your own.
