    I realize it drives a single output. Here’s my method. Assuming in dot mode it only drives one line at a time based on the Analog input. You tie all the 7 segment LED legs together that make up a 1 and tie that to the lowest LED input. Then tie all segments that make up a 2 together and tie that to the next LED input. Then when it hits that voltage it sinks current through all those segments lighting up the correct number.

    You could use one of these to drive a 1 digit display and get 0 to 9 displayed as the analog voltage increases. That would be a pretty cool and easy digital display for a throttle control, temp range etc.. without a microcontroller.

    Read the page a little more closely. Top left corner is a table of contents which lists the page example sketch

    Anyone know where to find a SIM Card Breakout. The difference being it’s a little simcard with wire extension. I want to use the board here at sparkfun to create a sim card extension cable. I haven’t had much success finding one.

    It does not support audio. I suggest the WT32 module by Bluegiga. I’ve used it and very easy to get a project going. http://www.mouser.com/ProductDetail/Bluegiga-Technologies/WT32-A-AI4/?qs=bzgYiMiT8X1PoaLuPkujPLxdARVg6opL

    I know my mom said if you can’t say anything nice don’t say it at all….BUT seriously!? That caption won?!!? That was probably the lamest, not funny, unoriginal one out there

    It’s made to charge a 1 cell Lithium poly battery. 4.2V is the max voltage you want a 1 cell to reach as you’re charging it. 3.7V is the nominal voltage of the cell. Fully charged it will sit at 4.2V. Once you start pulling current from it the voltage will sag to 4.1V down to 3.1ish then it’s dead and needs to be recharged. So yes it’s suitable.

    You guys should put a HUGE spotlight on the roof and everytime a gift code is given away it blasts a laser beam to space. That way we can see how well its going from afar…

    hmmmmm have you tried changing the Baud rate or contrast of the screen via commands? Did you put put slashes between the commands like the data sheet? ie CONF/30\n\r which would return the beep setting of the unit?

    I posted this earlier but for some reason it posted in a random spot on the page and don’t think Nate saw it. So here goes again.

    I found something interesting that may be of use. http://www.engineeringsurveyor.com/software/tps-dna-online_v114.pdf and the site I found it on with links to a bunch of user manuals. http://www.engineeringsurveyor.com/utilities/#Leica_Programs

    Leica makes these TPS Total Stations and Digital Levels and provide the commands to interface via serial commands on purpose. If I was a betting man I would say they possibly use similar command structures across their systems to keep things easy. I also looked for the ‘?’ char in the document and found it showing up as the response from the unit which was VERY promising. They use a combination of GET, SET, PUT and CONF commands and they use slashes between commands which is kind of odd. I bet you might be able to come up with some combination of commands based on that structure that would get it to spit some data back to you.

    Such as some of the CONF commands can set units, date and time, rounding, baud rate, parity etc… and those seems like something that would be from a standard software base possibly.

    Unfortunately, I don’t have the time to buy the unit and try this out for myself but hopefully this gives you a new direction to look. Have FUN!

No public wish lists :(
