The scratch board is great. However Measure allows one to do the same
things by plugging in sensors costing about $1 or $2, while the
scratch board costs $25.

Measure, currently has no support for USB interfacing, but I'm sure it
can be done.

Edward Baafi of the Fablab has made a $2 sensor board that plugs into
the USB and is installed like a USB-keyboard and continuously sends
sensor values from the values sampled off the 3 ADC channels of the
AtTiny micro controller that he's used.


Any suggestions for Measure and sensors are most welcome.


kind regards
