Self reversing screws : Linear Products : ABSSAC Power Transmission The self-reversing screw product does not require the driven screw to change its direction of rotation to enable the nut to return to its original start position. The reciprocated bi-directional movement is achieved by using a follower blade in the nut, that is matched to the particular groove width and screw turn round on the screw. (Our self reversing screws, do not utilise ball bearings in their linear travel). There is not a standard range of this screw type as all designs are manufactured to meet the customer's individual specification. Typically, the self reversing lead screws take about 5 - 7 weeks to be manufactured.

DIY CNC If your at all interested in DIY CNC (do it yourself computer numerical control), then Instructables is the place to be. We've got detailed step by step instructions on how you can build your own CNC lasers, CNC mills, CNC foam cutters, self-replicating CNC's and even a CNC chocolate 3D printer! Start building a CNC device for your shop today and make something awesome! I think one of the best things about tools is that they can be used to make more tools! I decided to build a miniature milling machine for machining plastic parts, creating wax patterns and for drilli... The idea behind this Instructable was to fulfill my desire for a desktop sized CNC machine. Springs Machined : Specialist Products : ABSSAC Power Transmission Machined springs available from Abssac Limited are a formidable package and for those engineers familiar with the traditional wound spring format we are offering a new way of looking at both performance and attachment. As the name suggests, we supply a spring that is machined from one peice of material. The most demanding extension, compression, torsion, and lateral bending and translation spring applications can benefit from machined springs because of their superior function and inherent versatility.

How-To: Shrinkify Your Arduino Projects Ever since I started making projects with the Arduino, I’ve had a desire to shrink them down to a single, small circuit board. One of my first projects, a customizable SLR intervalometer, was packed in a phonebook-sized cardboard box and used the Arduino Deumilanove connected to a breadboard with jumper wires. I brought the box out to Central Park at 5am to make a timelapse of the sunrise, but when I got to the park, I spent 20 minutes fixing the connections between the Arduino, the breadboard, and the components. Since then, I’ve explored a few different ways of shrinking projects down and making them more robust. For the intervalometer, I designed a circuit board that had female header pins to seat an Arduino Nano.

My Space Balloon: Project Stratohab Success!! High School Student's Budget "We're making space more American. We're making space more democratic. We're making space more available, approachable and real to the average American." - James Muncy, President of Polispace As an avid maker and hobbyist, I support the open source initiative like the Arduino micro controller platform. THE STARTUP GENOME PROJECT DISCOVERS THE 'DNA' OF SUCCESSFUL TECHNOLOGY INNOVATION AND ENTREPRENEURSHIP If you spend much time with Web entrepreneurs or investors these days, it quickly becomes clear that "pivot" is the hottest term in Silicon Valley. It signifies a young company's shifting of focus, and everyone has an opinion about whether it's something start-ups should be doing or not. The answer, it seems, is yes. And as long as it's done at the right pace, it can even be an extremely lucrative and important step. In fact, young Web outfits that pivot once or twice can raise two-and-a-half times as much money, see 3.6 times the user growth, and are half as likely to scale too soon than start-ups that either never pivot or that do so more than twice. That was one of the major conclusions of the initial report of the Startup Genome project, an initiative put together by a group of Silicon Valley investors that aims to identify the DNA of successful Internet start-ups and the teams and investors that build them.

24 hour junk 3d scanner - LVL1 This is a cross post from my blog at makeawesomesh.it. It is a little late but I hope it is still useful. All of the code used can be pulled from this github repo.

Wireless Power A few years ago MIT created a system for transferring power wirelessly. They transmitted power over a two-meter distance, from the coil on the left to the coil on the right, where it powers a 60W light bulb. Back in 2006, this was a pretty cool thing. You can only imagine what the implications of something like this would be. Well, unlike most of us, we do not have the time or material goods like MIT has. Best RGB LEDs for any project (WS2812) When we're working with LEDs, we often like to control their state (on/off), brightness, and color. There are many, many different ways of going about this, but none are as compact a solution as the WS2812 RGB LED. In its tiny 5mm x 5mm package, the WS2812 includes 3 super bright LEDs (Red, Green, and Blue) and a compact driver circuit (WS2811) that only requires one data input to control the state, brightness, and color of the 3 LEDs. At the expense of needing only one data line to control 3 LEDs, there comes a demand for highly precise timing in the communication with the WS2811. For this reason, a real-time microcontroller (e.g., AVR, Arduino, PIC) is required. Sadly, a Linux-based microcomputer or an interpreted microcontroller such as the Netduino or Basic Stamp cannot provide the sufficient timing accuracy that is needed.
