Paper Blinky is a simple four LED circuit that allows you to develop Arduino code to turn the LEDs on and off in a variety of patterns. Rather than wiring the LEDs on a proto-board they are assembled on a permanent paper circuit; this allows you to rapidly plug in the circuit to demonstrate your…

Arduino Ottawa Contest #1

Our local Arduino Ottawa group created a design contest which required an Arduino design that uses a mystery component. The last day of the contest is June 10th so I had to get my project started quickly. To that end, I re-used as much of my paper car work as I could. This allowed me…

Paper Car Design

I have simplified the electronics for the paper car. My new design takes advantage of the WS2812B RGB LED which is easier to assemble because it reduces the component count from four down to one part. I also realized that while assembling the circuitry directly in copper foil is fun; it takes greater than an…

Paper Car 2014

I am re-visiting the paper car design in an attempt to make it more user friendly. Specifically I want to be able to guarantee that I can successfully complete a workshop with children as young as 10. While the initial car design was great as a one on one project it is difficult to build…

I decided to make a small PCB milling machine so that I could panellize the PCB boards I design. This is also an experiment in making a 3 axis CNC machine using a laser cutter. The preliminary work consists of defining a cutting pattern for tongue and groove joints that provide a tight friction fit…

Linear Actuator Stepper

I was trolling the web and came across a great deal on LM6U linear bearings ($0.50). I also managed to find six Nema 17 stepper motors for $20 delivered. So what am I going to do with these parts? I have decided to design a simple linear actuator to learn more about designing robotic machines.…
