Fresh hacks every day
Cellular shields for the Arduino have been around for ages, but this is the first one we’ve seen that turns your Arduino into a proper cell phone.
The shield is based around the SIM900 GSM/GPRS radio module, and is compatible with the SIM908 GSM/GPRS module that adds a GPS receiver. Also on board this shield are a pair of 1/8″ … Read the rest
In case the Realtek RTL2832u-based USB TV tuner dongle isn’t useful enough, the folks behind a project to get a software defined GPS receiver off the ground successfully plotted GPS data in real-time with this very inexpensive radio.
Previously, we’ve seen these dongles grab data from GPS satellites - useful if you’re building a GPS-based clock – but this build … Read the rest
[Becky Stern] came up with a way to make sure you and your dog are getting enough exercise. It’s a dog collar mounted GPS that measures how far you have walked. Just set your target distance and the progress bar in the middle of this flower will let you know when you reached it.
The most obvious piece of hardware … Read the rest
A couple folks over at the Radionavigation Lab at UT Austin successfully spoofed GPS to take control of a small helicopter drone this weekend. Of course, this attracted the attention of the Department of Homeland security, so you’d better stock up on GPS spoofing equipment while there’s still time.
The DHS, CIA, and US Military have a huge interest in … Read the rest
Originally, [Karman] wanted to build a speedometer for his bike. Feature creep makes fools of us all, so after a month of work [Karman] had a GPS-enabled cube that tells him his current latitude and longitude, current time, course, direction and speed.
[Karman]‘s GPS cube uses a cheap GPS module, Arduino Mini Pro, a magnificent OLED display, and a … Read the rest
[Stephanie] just finished up her wearable project which puts a lot of information where a wristwatch would normally be found. She calls it the Integrated Sensors Electronic Bracer. We had to look up what a bracer is; the name originates with archers and it was a leather wrap used to protect the wrist. This does that, but we don’t … Read the rest
[Jason Wright] and [Jeremy Blum] are showing off the project they developed for their Designing with Microcontrollers course at Cornell University. They call it the Heliowatcher, and if you know your Greek mythology we’d be you figured out this watches the movement of the sun and adjust a solar panel to follow it.
Their design is simple and effective. The … Read the rest
