This isn't new. There was a university in the UK doing this about 15 years ago. They were trying to get industrial backing for it, but I don't think they ever managed to. One of their guys came for an interview at my group (different university). #xeroxprintablecircuits

Uh, okay... gravy for you! Feel better now that you vented?

@Zomb: It's not an opinion. It is just someone once again complaining about the articles. "This isn't new. I've seen this before. Why are you posting this? This isn't news. etc. etc." I just want to know the point of it all. #xeroxprintablecircuits

@ZaxxonQ.com: Ha, ha! Yes, it might sound like that, but it doesn't make it any less true.

I can tell you that I've sat through several papers on the earlier work at IMAPS conferences (International Microelectronics and Packaging Society) and I felt it was fair to give credit to that team.

Actually, I just remembered it was Brunel University and a quick Google comes up with this link from the Wikipedia page on printed electronics: [www.dea.brunel.ac.uk]

As a professional electronics engineer with a Ph.D. I suspect I'm rather better qualified than you to discuss this. While my comment might not have been of interest to low-brows like yourself, I was addressing it to educated people with a sense of curiosity. #xeroxprintablecircuits

They're using silver ink? Doesn't sound very cost effective. #xeroxprintablecircuits

Fantastic! The will lead the way for even more inexpensive electronics in the future. I suppose the only limits will be the resolution of the printer and finding a way to attach chips, powers supplies, resistors etc... #xeroxprintablecircuits

@Bertone77: I used to burn circuit boards in high school using copper boards, magic markers, and acid, this seems much simpler, way easier to fix any mistakes, all you'd have to do is fix the design in whatever program you used to design the circuit, rather than re-draw an entire circuit and re-burn the board, the installation of the chips and other components wouldn't be any harder than with the copper board, perhaps even easier depending on the material your printing on, and as far as resolution goes, the machine i'm running is 600 dpi for scanning, 2400 x 2400 dpi print resolution #xeroxprintablecircuits

@Bertone77: Yeah, the resolution's a big issue in any burgeoning printing project. Finding an appropriate solute/solvent system is a bitch, considering how things like polarity, solute particle size, and viscosity all strongly affect printing resolution and drying time. #xeroxprintablecircuits

Hah! I remember working at CERN in 1989. There was trouble with the ethernet network. In those days you made a connection to the CERN "Backbone" by putting a special clamp around the thick coax cable, like the one in the picture, that had two spikes that punctured the insulation. One was short and made a connection with the grounded sheath the other was longer and reached to the core. A very delicate beast. What we found was that some enterprising physicists had tapped into the backbone using two blocks of wood and a couple of nails. It worked for them but caused terrible signal reflections that screwed anyone upstream.

@daqman: I'm thankful that by the time I hit networking that the world was busily shifting from Thick/Thin (10base2) net to 10baseT instead.

Then again I remember crawling along the cable tray 40' up dragging coax behind me. Eventually I just started tying a string to a remote control 4x4 pickup (needed the wheel clearance) to pull a leader string, and then ran the cable that way instead.

I recently bought a dot matrix printer on E Bay. I do a lot of printing for school, my kid, etc, that doesnt require high quality and those printers are work horses and supplies are cheapo! I expect I will still be using it when I retire in a hundred or so years.

@Curves: I still specify that the Epson LQ-2180 be used on control projects (old number was LQ-2080 for the geeks in the crowd). The new models have RJ-45, USB and LPT ports on them or option for it. These things are tanks. They can print all day long on wide carriage paper.

@TheCapt: Ahhhh the sound of a dot matrix printer, as it goes back and forth, and like telephone "bells" and the click clack of typewriters, a sound you dont hear much any more.

Changing a printer ribbon is a lost art.

i still use a press i crank by hand. nothing like setting the type yourself and rolling 5 sheets per minute. i am also the local town crier.

Let me preface this comment by saying it has been a few years since I looked at this color printing technology; as such, it is possible it has improved. That said...

1) If you are printing heavy areas of color, it LOOKS waxy, not at all natural.

2) As a wax rather than a fused toner or an absorbed ink, it sits on the surface quite delicately and can easily be scratched off and/or flake off, especially along fold lines, making it a terrible choice for many uses.

3) Finally, even if the wax does not flake off, minor abrasions, such as might happen when a fingernail touches or moves along the surface, leave a quite-visible mark.

Again, those observations were from samples seen a few years ago, but I'd seriously investigate these flaws prior to purchase, especially at the MSRP indicated.

How many times are we going to see this bit about Xerox's "new" waxy ink on this site? :)

We saw christmas ornaments made out of it, and a few other things. But really what it comes down to is that this isn't new for Xerox. It's been out for a while.
