Tiny Transmitter Tracks Targets

Posted on by

It is a staple of spy movies. The hero — or sometimes the bad guy — sticks a device never any bigger than an Alka Seltzer to a vehicle or a person and then tracks it anywhere it goes in the world. Real world physics makes it hard to imagine a device like that for a lot of reasons. Tiny power supplies mean tiny lifetime and low power. Tiny antennas and low power probably add up to short range. However, [Tom’s] Hackaday.io project maybe as close as you can get to a James Bond-style tracker. You can see a video …read more

Inside an Amateur Bugging Device

Posted on by

[Mitch] got interested in the S8 “data line locator” so he did the work to tear into its hardware and software. If you haven’t seen these, they appear to be a USB cable. However, inside the USB plug is a small GSM radio that allows you to query the device for its location, listen on a tiny microphone, or even have it call you back when it hears something. The idea is that you plug the cable into your car charger and a thief would never know it was a tracking device. Of course, you can probably think of less …read more

GPS Tracker Gets SMS Upgrade

Posted on by

In May of 2000, then-President Bill Clinton signed a directive that would improve the accuracy of GPS for anyone. Before this switch was flipped, this ability was only available to the military. What followed was an onslaught of GPS devices most noticeable in everyday navigation systems. The large amount of new devices on the market also drove the price down to the point where almost anyone can build their own GPS tracking device from scratch.

The GPS tracker that [Vadim] created makes use not just of GPS, but of the GSM network as well. He uses a Neoway M590 GSM …read more

A Simple, DIY GPS Tracker

Posted on by

Today, there are dozens of off-the-shelf solutions for a GPS tracking device. Most of them use GSM, some of them use satellites, and all of them are astonishingly inexpensive. If you want to track a car, dog, or your luggage, you’ve never had more options.

[Emilio] wanted to track his own car, and the original solution for this was a smartphone. This smartphone was also a good choice, as it’s a programmable GPS device connected to a cell network, but there had to be a simpler solution. It came in the form of an eight euro GPS module and a …read more

Real-Time Planet Tracker With Laser-Point Accuracy

Posted on by

Space. The final frontier. Unfortunately, the vast majority of us are planet-locked until further notice. If you are dedicated hobbyist astronomer, you probably already have the rough positions of the planets memorized. But what if you want to know them exactly from the comfort of your room and educate yourself at the same time? [Shubham Paul] has gone the extra parsec to build a Real-Time Planet Tracker that calculates their locations using Kepler’s Laws with exacting precision.

An Arduino Mega provides the brains, while 3.5-turn-pan and 180-degree-tilt servos are the brawn. A potentiometer and switch allow for for planet and …read more

Fitness Tracker Teardown is a Lesson In Design for Manufacture

Posted on by

If the trends are anything to go on, after the success of Fitbit we are nearing a sort of fitness tracker singularity. Soon there will be more fitness trackers on wrists and ankles then there will be stars in the sky. We will have entire generations who will grow up not knowing what life is like without the ever-present hug of a heart monitor strapped across their chest. Until then though, we can learn a bit of design for manufacture from this excellent teardown of a watch shaped fitness tracker.

This tracker has a nice round e-paper screen, which could …read more
