The Brother ScanNCut uses a separate pen holder with specific sized felt tip ink pens to draw your designs. I want to plot electronic traces, but Brother doesn’t manufacture conductive ink pen cartridges so Denis and I began to hack together a solution.   First we took apart an existing pen holder and cleaned both the felt tip and […]

  An electronic trace made from CuPro conductive paint from LessEMF oxidizes over time, but it will still conduct current. Use a multimeter to test the trace for continuity then attach the power source to areas of paint that have not oxidized.     If the power source is attached to the oxidized areas the circuit will not activate.   […]

  Finding the right method for applying conductive paint to paper and fabrics is tricky business. The following tools are some of my favorite applicators for using CUPro conductive paint from LessEMF.   Stampendous Needle Nose Tip Bottles are about 50 cents USD and come in a variety of sizes and applicator tips.     The Find website is generally […]

  You’ve purchased a quart of conductive paint, pried the can open, and now you’re wondering how to use it? Not to worry! All you need is a piston syringe to transfer the paint from the can to a squeeze bottle of your choosing.   I found these 60 cc syringes on Amazon.   The least expensive option is a […]

CUPro paint from LessEMF in Albany New York is water based, therefore it is not a flammable substance and should be allowed as cargo on planes.   When I travel I print out TSA’s website for prohibited items indicating that there is no limit to the size of the container. I also print the CUPro paint data sheet again indicating […]
