Though it was less than a year ago, how I discovered NiZn batteries is lost to the mists of time. Their 1.6V rating makes them useful in some situations, and a wayward AA cell provides another excuse to play with scope math.
I do remember why I was searching, however. My DSLR camera was not working well with my various NiMH AA cells--it never had, but had become even worse. Surely all the cells couldn't have gone bad. My assumption, borne out by some web searching, was that the camera's battery sense threshold was a bit too high. Maybe it was in my search that I stumbled across mention of this new (actually, not so new) chemistry--newly available at least--Nickel Zinc, with a 1.6V cell voltage. That seemed a good candidate to make my camera happy.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
