Our attention was drawn to a new graphing calculator from NumWorks that it says brings the category (which it estimates at 4 million units per year) up to date as the market leaders were ‘designed in the nineties’ (by TI & Casio).
The device is open source and all the technical diagrams can be accessed on the site and, unlike other devices, NumWorks can be taken to pieces and put back together again. It has a 2.8″ diagonal 320 x 240 LCD display. The processor is a 100MHz Arm v7 processor with 1MB of ROM and 256K of RAM.
The calculator has a micro USB port and can be used for 20 hours without being recharged and spend several years in deep sleep mode.
It weighs 167 grams (5.9 ounces) and is 10 millimeters (0.4 inch) thick, making it the slimmest and lightest device in the world, the company claims.
NumWorks: the standard retail price today is $99.99.
