The site BIGGEST DRAWING IN THE WORLD details a GPS-briefcase trip throughout the world, creating a “drawing” which might the largest art piece ever created… via SparkFun. As others have commented… this seems a little fishy, but it’s possible.
This “Butterfly GPS” device was built with an ATmega169 microcontroller, a GPS receiver board based on the SiRF chipset, and an LCD screen that reads out the data in real-time as location, date and time. Very simple construction and nice details on how it was built at the PDF link below. A Butterfly GPS (PDF), […]
Our friends at SparkFun Electronics have a fun Maker Faire wrap up and have some new things in stock… At Maker Faire I joked with Nathan the CEO, that SparkFun should do a credit card with a loyalty program, I’d totally trade miles for transistors. Here are some of their latest products that looked interesting […]
Mike writes in about his super-cool Open GPS Tracker. Here is the simplest build-it-yourself GPS tracker yet. No expensive GSM module required – I am using the $20 GoPhone from WalMart or Target. Uses a 14-pin AVR microcontroller, a voltage regulator, a transistor, a GPS module 2 inches across, and that’s it. My open source […]
Remember that $35 GPS we posted about? Some Makers out there started to get theirs and are taking them apart – and MAKE reader “TheBigGroundhog” got it working…Flickr set of photos – Link. Getting it to work: From the MAKE comments – Maker TheBigGroundhog writes — Just got mine working today, and I was a […]
Earlier, we posted about the DIY cheap GPS tracking service Mologogo, you can get a cheap $60 pre-paid boost mobile phone, register on the site, download a Java app and you’re pretty much done. The phone will transmit your position to server (Uses Rails, Linux, Google Maps) and you/your friends can view where you are at in real time. I’ve hacked up tons of solutions to do the same thing, and this is simplest and cheapest (pretty much free if you have the phone, or $60 if you go pre-paid + 0.20 / day). Here are some photos and screenshots of the service in use…
Here’s a how-to on building a low cost vehicle tracker using the Telit GM862-GPS module. The GM862-GPS is a hardware module that supports connections on local GSM networks as well as GPS signals. In addition, this device supports a Python interpreter which allows for easy interfacing to build a simple tracker. Lots of info at […]
