Here we have a very strange gadget. It is a spy camera with built in calculator. I cant imagine why it was built except for someone spying and when getting caught just saying, sorry... I was doing some arithmetic. The spy camera calculator costs $69.99 and features a whopping 300k CMOS sensor with 8k of memory. Resolutions run from 1280 x 960 down to 640 x 480. I kind of get the impression that this was made back in the 90s
