Quantum dot image sensors set to change camera industry

Quantum dot image sensors set to change camera industry

Those of you who, like me, just recently managed to score the digital camera of your dreams will be very excited to learn that it’s possibly going to be obsolete real soon. Based on technology developed by University of Toronto professor Ted Sargent, who is now CTO at start-up InVisage, the new image sensor uses a matrix of nanoparticles embedded in a polymer film which can be simply “painted” onto the top of a low-cost wafer at room temperature. If the hype is to be believed, the new sensor offers four times the sensitivity of conventional CMOS image sensors at a dramatically reduced cost per chip. [Thanks, Glen!]

Hollow spy bolts

Hollow spy bolts

Brian Dereu of Hollow Spy Coins showed us how to make this hollow dead-drop bolt for stashing secret messages back in MAKE 16. It’s not hard to do if you have access to the necessary equipment–a drill press, hacksaw, vise, grinder, and the appropriate taps and dies. But if you don’t have those tools, or you don’t have the time to use them, and you still want a spy bolt, Brian will gladly sell you one hand-made by his family and him for the not-unreasonable price of $37.
