content: Yeah you probably saw something like this:http://www.mgchemicals.com/products/prototyping-and-circuit-repair/pens/silver-conductive-8420-p/They outline in the kick starter write up why they are better than the 'unnamed competition'. No smearing, quick dry etc...

content: They don't claim to be the first, they claim to be the first that's "ink-like" enough to make sharp lines on a page. They might be right there, those conductive pens are crap.

content: I usually use window demister repair pens, they work much better than the silver ink pens. Much cheaper too, not as low resistance but ey, cant have everything.

content: Conductive inks do have uses, but not for making a pcb. They work well for making connections to ultra fine wires, in microphones for example.I think it would be beneficial to show, everything has it's place.

content: Quote from: EEVblog on March 19, 2014, 12:47:19 amSure, please try it out for us.The problem I've had with conductive ink pens is that I don't need one very often, and the shelf life is poor, so I only get one or two uses out of each one

content: I once repaired a Sun workstation keyboard with one of those conductive pens. There had been water damage inside and most of the traces on the plastic membrane had corroded away. I retraced all the spots that didn't look good and restored the keyboard to working order.

content: To reopen an old thread...Got these as a gift from my mechanical engineering student son. Thought you would like to see what $45 USD gets you from them, post Kickstarter. It's a cute idea but I don't see much use for it outside of education or the novelty aspect. Personally, I think they're very much overpriced. No project book came with the basic kit, it's an additional $15.

content: It's something I have a hard time to get my head around, non technical people I spoke to say they'd like such a pen and find the idea fun!I would dismiss it after flashing an LED and probably cursing the erratic connections between the ink and anything else.I think wires would be better and not ruin the learning experience.But I am completely dismissing the fun part of this, drawing pretty pictures and then make stuff blink >.<I would not be the one making money with it.Conductive ink to repair circuits or use it in fabric to create antennas is a different story for me.
