Clean up your Prusa i3 wiring with cable chain

cable chain

CNC machines like 3D printers all need cable chain (aka drag chain). There’s always some wire that has to be loose so it can connect to things that are in motion. Loose cable could catch on something and is an accident waiting to happen. Cable chain only bends one way. It can keep those wires out of danger by making them only move in a safe zone. Here’s how I did mine, with video of it in action.

A DIY RGB LED scrolling message ticker

Going Crazy? Stay Busy

Happy Winter seasonal festive time to you all. I wrote another new instructable to help you stay sane through the holidays: a full-color LED message ticker. You can change the message without reprogramming anything.

Check out the RGB LED scrolling message tutorial on instructables.

Imagine it in your xmas tree!

2015 Projects

Now that I’ve got the M3 to Prusa i3 out of the way, my new priority is a gearbox I’m going to need to build my next robot arm. From January to end of March I have three university students helping me build the arm. Around that as I have time I’ll be programming my first custom PCB and bringing out another new robot that’s still deep under wraps.

Maybe after all that I’ll take a break for summer. LED art to Burning Man 2015, anyone?

Programming LEDs with Arduino 201: A dynamic rainbow ASCII marquee

I’ve been teaching Arduino LED programming classes as VHS and now MakerLabs here in Vancouver. Together we learn how to write a simple Arduino program that introduces conditions, loops, variables, and methods. It seems to go over pretty well.

At the end of the class I told people I would post a 201-level example of a dynamic scrolling ticker marquee. Word is bond, yo.

How to

– Upload this code same as in the class.
– Open the serial window.
– Set baud to 57600 and “send newline”.
– type a message at the top of the serial window and hit “send”. Your message appears on the marquee.
– Read through it to see how it be like it do.
