I am still hunting for diy camera sensor.
I read at a magazine that jacobsen from mit media lab says that he came to mit for to transform 1 cent plastic with 1 cent technology to thousands worth of product.
He prints or hand stamps pentium detail cpus to plastic surfaces.
His acrylic laser engraved hand stamps print same detail with intel.
Intel produce these details in 3 weeks , 550 processes and 1 billion dollar factory.
I first interested in using small leds for to create my own ccd. a harvard technology.
later i learned that leds needed intense and short pulses for to be worked.
Than I interested in plastic transistors and there are many patents outthere but they reported as slow.
I now interested in liquid phase epitaxy for to create my own transistors .
i learned that this technology requires crystal surfaces.
What about coating crystal powders - like shaving a cheap cpu or laser rod -
Than printing on coded transparent conductor coated film .
People make their transistors and earn a living with coating crsystals surfaces and make their transistor
And there is also steel aluminium contact semiconductors.
May be we can inkjet nanopowder of aluminium on stainless steel plate , heat and make a enamel transistor ?

What do you say ?

Best ,

hey 3D...cool link

Lindsay's has some great books

I never made a vacuum tube, but I did make a gas discharge tube ages ago....passing 15,000 volts or so through air at low pressure made a nice red glow from the nitrogen

i think mixing crystals and chemicals and inkjeting them are mit technology , after 8 years of its invention , i reinvented it. epson have a interesting research on inkjeting silicone on to surface.

Wow. Damn. I didn't know they were still around! I used to order their catalogs in the 80s... been a LONG time now...!!

I'm sorry but LED will not sense photons the structure is all wrong for that. CCD or Cmos photo sensors are many layered structures and there is not any known equivalent method for printing a structure that functions in place of a CCD or CMOS. The other problem is speed of operation, current printed circuits (lab printed using ink jet type printers) have a very low operational frequency below 10 meg Hz.

That is not true. LEDs are light sensitive but are not optimized for the purpose. Radio Shack used to publish project books that included projects using LEDs to sense light. A photodiode uses the same process but is optimized for the purpose.
