  1. I guess that too.

    Today i tried what i got from the SCB 68 manuals for differial input. I connected a small 9V battery and place a 100ohms resistor acros a specified place on the PCB of the SCB 68. It was able to record the voltage as expected. However all the channels indicted values close to 9.1 V.

    I expect only the channel with the battery to record this.

    If the other channels are not connected to anything, their readings will tend to 'float' around the values of adjacent channel(s). This is due to the high input impedance on the front end of the analog to digital converter and the inherent capacitance of the input stage. The capacitance charges up and holds the voltage since there is hardly any path for it to discharge into.

    You need a short wave radio with a good long wire (not the LabVIEW kind :rolleyes: ). You can hear BBC straight from London any time. With luck you may be able to pick up some Australian stations. I don't think the 5th dimension will affect your reception :unsure:

  3. Eerc, I am not sure how one would use an SMS gateway to sent an sms to a cell phone. From what I have seen you would need to subscribe to some kind of service that allows you to do that.

    In searching for an answer to your question (I've been wondering myself how to do this), I have found that you may be able to send an sms to a phone by simply sending an email to the phone. In my case my mobile provider (US Cellular) allows an email to be sent to a phone. I can send an email to 'myphonenumber@email.uscc.net' and it will show up as a text message on my phone. Other providers may allow this or provide it as a service (maybe for free).

    Check with your mobile provider if you can do this.

    I hope this helps

    You can subscribe to a web service and probably do sms. Xmethods has a host of services, search SMS at this link:

    Here is a link for using services in 8.2

    And for 7.0 and 8.0

    I tried one of the services in 8.2 to dial my cell and read aloud a message that was text. All in about 10 minutes with never using web services- pretty cool.

    Hope this helps
