FIRST Robotics

This is slightly unrelated and only a thought but I think it would be to Sparkfun's advantage to become a sponsor of FRC and FIRST Robotics competitions: http://www.usfirst.org/roboticsprograms/frc (Sorry to lazy to make a fancy looking link). I have seen many bots with custom electronics like LED s...

Re: 3D Files

A prime example would be for a 3D model of the CMUcam. There is no good documentation that can really describe all of the dimensions on the board, in order to, for example, make an enclosure without very painful research that I do not have time for.

3D Files

Now before people go ranting on how this is too much work for too little benefit blah blah blah.... I think it would be interesting if SFE would make 3D models of their products. Yes, pictures are very very nice. That's one of the reasons SFE is where they are. But I have discovered a very interesti...

Re: NMEA from LS20031 error

I would agree with the above. The XBee does not draw a constant current throughout its operation. Thus, the voltage drop across the resistor will change, making the voltage very unreliable. Spend the extra dollar or so to save your $20 radio.

Re: PCB Design Review

I kept messing up the footprints, bad connections, I switched the GND and VCC on some of my chips. Just the stupid stuff.

Re: Setting up PICKit 3 Debug Express

Well, I do beleive the compilers automatically link to the correct files when compiling. It would be best not to touch those files. You did not install it wrong: I would see what version the tutorial is set up for.

Re: PCB Design Review

Glad to hear the boards work well! My first board took 5 revisions. Quite painful.

MPU9150 Register Map

Hello Everyone. I am looking for a document that seems non-existent. I am looking for the register map/description documentation of the MPU9150. I have looked across the web and have found no such documents detailing the registers for this amazing device. Here is the main datasheet, rev. 4: MPU9150 ...

Re: Big Time II Watch

Arduino's IDE is free to download. Again the only other investment would be the FTDI chip. Which I love so even if you don't go through with doing your project, get because its such a nice cheap debugging tool.

Re: Sending 100K data over WiFi

Well from a network standpoint you can only get 800 bits per GET request. (100 (I think) ASCII chars * 8 bits a piece). A POST request on the other hand has no size limitations.

Re: LED Circular Bargraph Soldering Options

No. Im talking about a copper clad board from Radio Shack or somewhere like that. Just stick the pins through and cut out where you don't want stuff. Then just point to point solder to the pins from the board.

Re: Options to Multiple Loops on Arduino

Parallel Processing? Not in arduino. You could however use interrupts.

Re: Big Time II Watch

Well just to get it working, you would need soldering equipment and a battery. To actually reprogram it, you would need a FTDI breakout, which is a great tool in general even if you are not working with arduino. I use mine in developing all of my projects.

Re: Quadcopter Communication

From my experience from making a HID host keyboard application from Microchips libraries, and the fact that the modem probably an unreleased custom driver, using a USB 3G Dongle host is next to impossible for a hobbyist.

Re: LED Circular Bargraph Soldering Options

You should be able to get a breadboard and just cut out the center or wherever you need the switch to be, then solder the wires to the pins. The breadboard will reinforce each of the pins preventing them from breaking off.
