There’s been an explosion of interest in conductive ink from hobbyists, and with good reason: the ability to literally draw a working circuit on a piece of card is great for education. When it comes to attaching components to said circuits, however, things get tricky - a problem Allen Pan believes he has solved with Conductak, an adhesive putty that conducts electricity. Allen is still working on the formulation, in particular on getting the resistance down to acceptable levels, and is seeking a modest $2,250 on crowd-funding site Kickstarter to experiment with new formulations. Allen has also demonstrated Conductak working with surface-mount devices (SMDs) over on Instructables.
Conductak is an electrically conductive sticky tack! I've been developing it on and off for a few months now, and I've gotten to the point where Conductak can be used in conjunction with conductive writers like Circuit Scribe to draw circuits with off the shelf components.
