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)

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

    Please, ERIED, can you say me song name in this video? Congratulations, buddy!

  3. 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.
