Let’s not ignore the Elephant in the Room

elephant zeoscopeToday we had a herd of Elephants running around here at CTH. They are 3D printed and part of Dmitriy’s most recent project, a three dimensional zoetrope. He started by modeling 10 different elephants, each representing one-tenth of a stride. Each model is printed and attached to a spinning disk powered by a stepper motor. A bank of LEDs flash 10 times per revolution resulting in the illusion that the elephants are running. The contraption is powered by an old ATX power supply, 12v going to the stepper motor and 5v for the logic. An Arduino controls the stepper motor and times the LEDs.

Milling Machine Fundamentals

CTH Equipment Workshop

Have you ever wanted to learn how to use a Milling Machine? At our most recent “Intro to the CTH Workshop“, Matt gave a great overview of our Bridgeport milling machine. Attendees learned the specific uses for drilling, milling and boring as well as how to change the tool in the machine. Matt also went over using an edge finder and the DRO (digital readout) for super accurate positioning. Now, no piece of metal is safe from modification into some cool project. Each “Intro to the CTH Workshop” will focus on a different piece of equipment. Future workshops will be listed on MeetUp.

Improvising – Using One tool in the Hacker Toolbox

Success in a roundabout way thanks to improvising.

Hacking is finding your solution and obtaining your goal by out of the box thinking.

One of our projects has been trying to interface an old Vinyl Cutter / Plotter with newer software options (post 1996!) After months verifying separate components, we still have been unable to get get it all of the parts to correctly work as a system. (if you know Linux, Serial, and HPGL we would love help in getting our hardware fired up correctly!)


Custom CNC Mount for Vinyl Cutter Blade

At wit’s end, and help from everyone in the CTH community, the vinyl cutter cutting blade was installed in an improvised mount that was interchangeable with our  operational hand-built CNC router. The vector logo file was loaded and cleaned up in Draft Site. We then converted the image to g-code (compatible the router software) with a 1/16 cut depth.
