  • I have a question about using these with the geophone. I have two of these op amp break out boards and I'm wondering if I can use two of these, each lead from the geophone wired to the input of each op amp, then have the outputs of both going through its own voltage divider, center being 2.5vdc, then feed both into two analog pins of an arduino. Is this a good idea as far as getting an arduino friendly signal from the geophone? Think it would be wise to put a zener on each pin of the geophone leads to clamp it to 5.1vdc?

  • Ive seen hints to a Sparkfun Wunderground enabled weather station tutorial in this tutorial and elsewhere, even a link at the end of this tutorial, but it doesn't go to anywhere but the learn.sparkfun.com site. When is it going to be available? I'm currently overhauling my weather station to send data to Wunderground using the new weather shield, but im using a Arduino Mega because i need more I/O, (for soil temps, soil moisture, UV, leaf wetness, etc.). I'd like to see how this tutorial will come out and with what features i may be able to use in mine.

  • i too ran into that problem i'm not sure why it does that,(it did seem that at first it wouldn't read the data but after about 3-4 min, it would read everything fine), but i found that if you shut the software down and reboot the board, wait for the board to reboot, (status led flashing at the preset data transfer interval) then start the software, it will then start receiving data. be sure to set the board to output csv data, not ansi and baud rate at 9600. it should then be working. hope this helps.

  • After some trial and error this morning, when trying to add the external TEMT6000 BOB, you must reverse the vcc and gnd to the sensor in order for the usb weather board to read the light correctly. before i was reading 0.0% in full light, after studying the schematics for both, i found that the BOB reads the signal from the GND side while the usb weather board reads the signal from the vcc side. simply switching the vcc and gnd fixed the issue. also, the 10k resistor on the TEMT6000 BOB needs to be changed to a 1k like on the usb weather board in order for the voltage to scale correctly

  • i think, for the most part, the comments above, people are not seeing the true meaning or intended usefulness of these battery packs. they are NOT designed to be used as an higher current source than the single cell 2000mah batteries, but as a longer use battery, you will get theoretically 3 times the usefulness 3.7vdc 1000mah (as determined by the connector/wiring) power to use in a project, ie. you wont have to charge as many times between uses where as if you use one of the single 3.7 2000mah lipo's. also if you're getting 3 times the use between chargings, expect 3 times the charging time to full charge.

  • I have asked Brian, of weather-display software,


    to add support for this board. after a week of beta testing with him, he has released a new version of the software that now supports the sparkfun usb weather board. i have used this software in the past and if you're serious about weather, this is the software to use! Go check it out and if anyone has questions on how to set it up with the sparkfun usb weather board, just ask me and ill be glad to help!

  • i had this problem also, no matter what software i used. what i did was open up the code and change the:

    if (Serial.read() == 0x1A) // CTRL-Z


    if (Serial.read() == 0x6A) // lowercase j

    then all you do is press 'j' to access the menu.

  • It's all good, it's working now and i can proceed with my project. things happen sometimes and in no way does this affect me buying from you guys again. Sparkfun ROCKS!

  • FYI, i could use a set of the weather meters for my troubles when they come back in stock. ;)

  • Well, the one i got today, the humidity sensor was crooked on the board, with 2 of the legs with no solder on them or connected whatsoever. i took pics, then soldered them and it worked fine. i didn't notice it till i connected it to the pc through usb and the humidity and humidity temp were reading negative values and saying "FAIL". i figured i'd just fix it myself instead of going through the hassle of sending it back and waiting for a new one.
