Automated Wire Cutter And Stripper

Kit builder oomlout—we’ve featured their servo bot—needed to produce a lot of precut wires. After cutting and stripping more than their fair share, they decided to apply some heavy engineering to make things easier. They constructed a machine to do the job for them. It has three main components: a servo driven wire feeder to measure the length, a two servo wire stripper that uses an exacto blade, and finally a wire cutter made from snips and a drill motor. The machine is controlled using an Arduino. They’ve published all the plans and code to Thingiverse incase anyone else wants to build a similar machine for their own kit shop. A video of the machine is embedded below.

Laser Cut Pumps

As the video above shows, [Zach Hoeken] is continuing to improve on his peristaltic pump design. The moving parts in peristaltic pumps never contact the fluid being moved. Instead, they interact with the outside of the tubing that’s carrying the liquid. In [Zach]’s design, multiple skate bearings roll across the outside of the silicon tubing, squeezing the liquid through. You can get a better idea of how this works by watching the first video. The newer version appears to be pumping much better. We’re not sure if that’s because of faster motors or from switching to two bearings instead of three. This definitely looks like a good choice if you’re planning on building your own cocktail robot. You can find the plans on Thingiverse.

Acrylic Tumbler Lock

Sometimes describing how a lock actually works can be the hardest part of teaching someone about lockpicking. [Mike Gee] has designed an acrylic lock that may just be the ticket for these situations. All of the pieces are cut from clear acrylic. As you insert the key, you can see it raise the four pins up to the shear line. He says that it will definitely take some tweaking as you assemble it to get it to function smoothly. Embedded below is a video of the lock in use. You can find plans on Thingiverse.

Gears Embedded In Business Cards

In [Bre Pettis]’s latest “things” video, he talks with [Adam Mayer] about his geared business cards. [Adam] has designed several versions of these cards that have functional gear systems in them. There appears to be a simple two gear one and a more complicated planetary gear set up. The designs have been uploaded to Thingiverse, so you can download and build your own.

SketchUp Adds Dynamic Components

Google just announced the release of SketchUp 7. SketchUp is a 3D modeling program with a fairly robust free version. They’ve added quite a few features and the one that caught our eye in particular was dynamic components. Dynamic components have behavior specific to the object. The example in the video above shows a staircase changing the number of steps as its height is increased instead of distorting the overall staircase shape. The new version also allows for interaction, so model properties change based on user actions.

Google has always encouraged sharing of objects created in SketchUp. Thingiverse launched today with a similar emphasis. The site is built to encourage the exchange of plans for physical objects. It supports many different file types from plain images, AutoCAD dxfs to Eagle schematics. Many of the designs already posted are made to be cut out by a laser cutter or built by a 3D printer.
