  • After 137 hours of testing every possible button and duration permutation, I can say with a high degree of certainty that my Victor 70C does not have the ability to keep its backlight on. To counteract my bad investment, and to enable its use in the field (or anywhere, really), I resorted to buying a headlamp. But the headlamp rubber quickly stretched out, and I had to buy a trigger clamp to keep the headlamp affixed to my head. The multimeter now dangles from the clamp rod, allowing me to read the multimeter with the headlamp, hands-free. Literal AND figurative headaches. Awesome!

  • Awesome, thanks! That library looks like it was put together with much more thought. In my tests, the code I posted above produces accurate temperature and altitude results. The Weather Board (Firmware 1.2) BMP085 library produces accurate temperature, but my sea level altitude (61 meters) is incorrectly reported as 1655 meters. I’ll post my findings if I find a solution :)

  • Immense gratitude to the makers of the world who take the time to explore and share their findings. After 13 hours of searching/dissecting/migrating posted snippets of code, I discovered that NOT ONE functional demo of the BMP085 for Arduino 1.0+ exists. Dysfunctional findings include:

    • the sparkfun tutorial @ http://www.sparkfun.com/tutorials/253
    • http://mitat.tuu.fi/?p=78
    • http://interactive-matter.eu/blog/2009/12/05/arduino-barometric-pressure-sensor-bmp085/
    • http://bildr.org/2011/06/bmp085-arduino/

    I was finally able to successfully debug the last article (@ bildr.org), mostly by fiddling with argument types. So if you replace the code in this otherwise awesome quickstart guide with this code … http://ilabbali.com/code/Arduino_BMP085.cpp … the BMP085 works great with Arduino 1.0+.

    I tried posting the code here, but the sparkfun WYSIWYG parser totally mangles it.

  • Ah… found the answer to this on the Product Page:

    “After calibration, the pH probe can be immersed in a liquid and operate continuously for 12 months before recalibration is recommended.”

  • 25 minutes of soldering, perfect output … 3.298V and 4.997V. Viva la SparkFun!
