ELE-0033 Bare Conductive Paint Pens have special ink that conducts electricity. Stick some LEDs and a battery to a piece of cardboard, then draw your circuit and the lights will work! This is great for architecture students who want to light their models. Surface Mount PCB prototyping has never been this cheap and fast.
ELE-0035 Adafruit Motor Shield v2 is a stackable version of the v1 shield – put three on one arduino and you can run 6 stepper motors at once. Hello! That’s a fancy 3D printer.
If you are familiar with the v1 shield you will find the instructions a breeze.
A few days ago I published code for a 2-axis CNC machine that runs on Gcode. Here is the same code updated for v2. Click here to see GcodeCNCDemo on Github.
I’ve updated the GCode CNC Demo on Github with an example of how to run 4 stepper motors. It could be extended to 6, 8, or more. Watch it in action
Jim has been making some heavy mods to his Makelangelo in his home lab and sharing his adventures in the forums. Watch his machine draw a bunny
