News - New Product Friday: The S…
about 2 months ago
Robert, Have you gone camera shy? This is like 3 or 4 weeks in a row without the venerable new product video post that many of us have tuned in for every Friday for years now. (and Thursdays before that) Individual project & product videos are great and appreciated, but all is not right with the world without your new product video each week. Even if you are just presenting more mundane updates to BOBs or new LEDs or what not, the weekly video was something we could count on to get our Sparkfun fix each week. If there isn’t much “new product” to talk about, how about augmenting the video with user projects, upcoming events, and other happenings with Sparkfun.

You can use the Openlog logger. It is not just a serial text logger. I’ve created a Flight Data Recorder for my Quadcopter and can capture a surprising amount of data, even 10ms sample loops if you are careful.
Thanks to some work Nathan did a year or so back, Openlog can be used in “binary” raw mode, in other words, it will record raw 8-bit bites into the log file at 115Kbps. I wrote a encoder library on the quadcopter’s Arduino Mega that provides a frame format for the data sent serially to the OpenLog stored in the file. There is a unique start sequence (2bites) followed by a record type byte, a compressed timestamp, the 8-bit raw data, and finally a one byte checksum. The PC side decoder figures out where packets start and finish in the raw file and decodes each value in each record. There can be a glitch from time to time so the checksum byte is important. Each record can be a unique list of values, for example, lat, long, alt, pressure, etc. Where possible I transmit binary equivalents to save time, for example, the NEMA text values for lat or long are converted to a binary form only taking 4 bytes each, and then reconverted to the original text string on the PC. Analog integer samples can be transmitted directly as can floating point. The PC decoder handles big/little endian conversion, floating point architecture mapping, etc and produces a text CSV file of the data that can be process in excel or whatever. In this way, I record mixtures of analog and digital sensor readings, all time stamped, using the Openlog. Works great.

A geo-logger. Combine an openlog & gps (GPS-11571) w/ some button cells or small lipo into a strip that can be integrated into a dog/cat collar or a bracelet. It would be a lot of fun to find out where the cat goes all night. It would be convenient in a bracelet format when cycling or hiking to keep a record of your route. Include a 6DOF sensor and it could monitor your golf swing.

I see a Remote potato gun igniter in my future!

There is some real entertainment value here. The build up, the scramble during the event, the post event cleanup and stats, the fire trucks standing by in the parking lot to douse the servers, EMTs ready when the poor IT guys succumb to the pressure. Customers staying home from work, giving up sleep, generally obsessed with getting a slice of the action.
Get Discovery Channel to make an episode around this - it would be as entertaining as Deadliest Catch, American Chopper, Cake Boss, etc. There is drama, there is excitement,there are winners and non-winners, there is a wholesome message about a very cool company making a real impact in the community it serves and lots of blinky lights and push buttons!.

Could you make a FLIR scanner out of this by mounting it on one of these ?
You’d have to do some delicate soldering to the ATmega to get access to a couple of PWM pins (too bad they aren’t broken out) to drive the servos.
Put it on a tripod, raster scan the wall, find out where the thermal leaks are.
I guess it would be better with the 10degree FOV sensor. Anyone know which exact sensor is on this board?

Just got my 5DOF and noticed the same thing. While the two rows of header vias are on 0.1 spacing they are not in alignment with each other on a 0.1 grid spacing (horizontally or vertically) making it difficult to use with a solderless, drilled breadboard or proto shield using pin headers. You can see this in the product pictures above if you look carefully. Now that they are out of stock, maybe SF will adjust the layout ever so slightly for the next PCB run.
