Conductak makes conductive sticky putty

Siggraph 2015: Add Circuit Stickers and AgIC pens and teach away

One of the most interesting things at Siggraph so far has been the conductive stickytack by Conductak. Coupled with Circuit Stickers and AgIC’s conductive ink, there are some cool projects you can design.

The idea is simple enough, take that blue sticky putty that you use to put posters on walls with and make a conductive version. That is what Conductak makes, they have a brown tacky putty that conducts electricity. If you have a couple of traces you want to put an LED between, put two globs of Conductak on it and press it on. It sticks and you have a functional connection. It isn’t that complex to explain but the doors it opens are.

Conductak and instructions

The black balls around the logo are Conductak

If you are thinking, “Shut up and solder it”, you are probably not the target market. It could be useful to have a glob of this around your lab for odd jobs and more frequently practical jokes, but that misses the point. If you are teaching kids how to design circuits or get them interested in Arduino type projects, this is a very safe and low burn quotient way to get them involved. It is perfect for schools too.

Conductak demos

As you can see from the projects above, you aren’t going to be making superscalar deeply pipelined OoO thingies with this stuff. What you will do is make electronics cheap, accessible, and safe to a whole new audience. If you look at the laser cut and embossed boards under the logo above, you can also see another potential audience, vision impaired geeks. If you can’t see it is really hard to solder so doing anything with electronics is orders of magnitude harder, molten metals are not a suitable material for braille. Conductak and embossed guides could change all of that.

Chibitronics Circuit Stickers

Sticky circuits

Couple this with the circuit stickers from Chibitronics, they make stickers with designs and components for a circuit on them. You just put traces down at the correct distance, stick an LED or resistor sticker on it, and voilà! See the above caveat about OoO projects, it applies here too. About the only thing that it and Conductak needs is to have a way to make traces easily and quickly, if only there was such a tool for the little spuds to make a functional killer robot with in third grade.AgIC pen and kitsAgIC to the rescue with conductive pens

AgIC to the rescue with pens that draw using conductive ink. It looks like a pen, writes like a pen, and more germane to the target audience, probably does not taste much like a normal pen. That said you can draw traces to put stickers and Conductak on with AgIC’s pens. It is almost like magic but with more science.

AgIC also can print stuff with their ink on an actual printer to achieve much finer results. If you look at the blue business cards by the pen, they are actually USB templates. On a paper business card, not a PCB one that is 3-4mm thick. This one has some possibilities doesn’t it? It may not change the world but it could be very useful and people won’t forget the card you hand them.

In the end Conductak is just getting started, it is not available yet but the other two products are. Conductak is working its way to market, they had an initial kickstarter offering to get a test batch done earlier and are probably going to do one for a product in the near future. If anyone reading this wants to do good for EE education, fund them ASAP. The other two are out and combined they could change a lot, for the better, in the educational arena. If you want toys for your kids that you can play with too, these three should be on your short list.S|A
