Hi: Has anyone made up a schematic for the Hobo H8 data logger. It uses a 16C56 with four external 24LC65 8kx8 bit memory chips and a TLC549 8 bit A/D IC. See my Hobo web page at: http://www.pacificsites.com/~brooke/Hobo.html I'd like to use some of the circuit for a Date + Time stamp recorder that would have 2 buttons as inputs and a small LCD to read the hacks back.
