K0balt 13 hours ago Paywall. Clickbait title. Checks out.Referring to batteries in low power devices like keyboards and calculators… so just like what’s been on the market for 3 decades? metalman 12 hours ago longer,light meters for film cameras back to the 1950's? further back K0balt 9 hours ago I thought usually those light meters used cadmium sulphide photocells? I don’t think they actually produced enough power to be useful in that way? Do they even have a photovoltaic effect? I always thought of them as photo resistive.
