Old HP48g Calculator + Arduino Decimila + Laser pointer + Light sensor: Cheap Laser Object Counter

http://www.ried.cl

Counting boxes on a miniature “production line” with a cheap laser pointer and a light sensor.

For more info about the HP48 connection with arduino (working as a complementary remote command device) take a look in http://groups.google.cl/group/comp.sys.hp48/browse_thread/thread/33468da10be79e93?hl=es# (I had to create a simply translator to virtually support the HP-Arduino I/O)

    can you offer any advice on how to create this exact system but instead output the count to an lcd display?

    you could’ve used …
    you could’ve used the 48’s IR to detect objects passing by.

    or a simple circuit with laser LEDs on the rs232.

    i think using the arduino was overkill.

    good work though.
