NMEA defines how most GPS receivers talk. When GPS is properly connected to a host controller like Arduino, it sends a never-ending stream of characters, grouped into human-readable clumps called “sentences”: $GPRMC,045103.000,A,3014.1984,N,09749.2872,W,0.67,161.46,030913,,,A*7C $GPGGA,045104.000,3014.1985,N,09749.2873,W,1,09,1.2,211.6,M,-22.5,M,,0000*62 Obviously, [...] Greater Accuracy with TinyGPS 13 September 1, 2013 2 TinyGPS 13 has been released. This latest revision improves the algorithm used to transform the raw NMEA latitude and longitude values into floating-point numbers representing decimal degrees. You may not have noticed any problem, but prior versions of TinyGPS generated values that were accurate to only about 5 decimal digits, or about 1 meter. Version [...] Talking to Satellites! June 13, 2013 12 We’ve been having lots of fun over the last few weeks playing with a revolutionary new satellite communications device by Rock 7 called the RockBLOCK. I say “revolutionary”, because when you hook it up to an Arduino–and this is super easy–you can inexpensively send and receive short “burst” messages for the first time from anywhere [...] The Evolution of the Reverse Geocache™ March 16, 2013 0 Back in 2009 we published the story of the first Reverse Geocache™ Puzzle. This site has since been a little bit schizophrenic, with articles on Arduino libraries on the one hand, and updates to the famous puzzle box story on the other. Well, today we announce a brand new website dedicated to all things to [...] Puzzle Box: The Poetry of the Quest January 6, 2012 10 It’s 2012 and we Texans are finally enjoying some relief from the hottest and driest year ever recorded. The rain and cool took their time coming. When storms blow through now we huddle at our office windows like clusters of excited honeybees. It’s hard to fight the impulse to wander shirtless in the streets. Quest [...] Engagements: A Tale of Two Cities January 18, 2011 6 I. Seattle Some pretty exciting news came my way last September. My friends at Groundspeak, the international geocaching organization, wrote that their Reverse Geocache™ Puzzle Box had recently facilitated a young coworker’s wedding engagement! (You’ve encountered this very box in an earlier post. I built it to celebrate geocaching’s tenth anniversary—the first commission I ever did.) [...] Welcome, MAKE readers! January 14, 2011 6 Welcome, MAKE readers! I’m very pleased that you dropped by and hope you enjoyed my article on the Reverse Geocache™ Puzzle Box (p. 144 of the January issue). We have a wonderful community of puzzle box owners, builders, and enthusiasts here, centered around the notion of location-based microcontroller projects, and we’d love for you to join [...] NewSoftSerial 11 (beta) January 5, 2011 85 The new year brings another version of the NewSoftSerial library, a beta version 11. Changes since version 10 include: Inheritance from the new Arduino Stream class and commensurate interface adjustments (added peek(), changed signature for available()) write() member is now public, following the lead of Print base class support for Arduino Mega and Mega 2560 [...] Puzzle Box 4: A Long Awaited Opening October 27, 2010 22 [Author's note: This post is the last in a real-life story that ultimately took a full year and four chapters (1, 2, 3, 4) to tell. Read them all, then browse through the other surprising puzzle box stories that have popped up along the way.] The Box Opens The big news we’ve been waiting so [...] The Reverse Geocache™ Puzzle Box hits YouTube August 29, 2010 3 As you may have read, the nice people at Groundspeak dropped by to interview me about the Reverse Geocache™ Puzzle. These were the folks who discovered afterwards that I had hidden their dinner — actually a gift certificate to a local Mexican restaurant — in one of my “elegant black” puzzle boxes. We had a nice [...] 1 2 3 » PagesAboutLibrariesFlashIridiumSBDNewSoftSerialPStringPWMServoStreamingTinyGPSTinyGPS++ProjectsThe Reverse Geocache™ PuzzleBuilding a Puzzle BoxBuying a Puzzle BoxMore Puzzle Box TalesSundial.comThe evolution of the Reverse Geocache™Recent PostsTinyGPS++: A New View of Global PositioningGreater Accuracy with TinyGPS 13Talking to Satellites!The Evolution of the Reverse Geocache™Puzzle Box: The Poetry of the QuestArchivesSeptember 2013June 2013March 2013January 2012January 2011October 2010August 2010July 2010February 2010January 2010November 2009October 2009May 2009April 2009March 2009February 2009January 2009 © 2022 Mikal Hart.
