Real Time Satellite Tracker Shows You What’s Going Over Your Head

Whilst modern technology relies heavily on satellites, it’s easy to forget they’re there; after all, it’s hard to comprehend mostly-invisible lumps of high-density tech whizzing around above you at ludicrous speeds. Of course, it’s not hard to comprehend if you’ve built a real-time satellite tracker which displays exactly what’s in orbit above your head at any given time. [Paul Klinger]’s creation shows the position of satellites passing through a cylinder of 200 km radius above the tracker.

Each layer of LEDs represents a specific band of altitude, whilst the colour of the LEDs and text on the screen represent the …read more

This Is Your Solution For Open Source Motion Tracking

The HTC Vive Tracker adds real-world objects to your virtual world. While these real-world objects in virtual environments are now mostly limited to a Nintendo Zapper for a Duck Hunt clone and a tennis racket, the future is clear: we’re going to be playing Duck Hunt and Wii Sports while wearing headsets. The future is so bright, it burns.

Of course, with any piece of neat computing hardware, there’s an opportunity for building an Open Source clone. That’s what [Drix] is doing with his Hackaday Prize entry. He’s created an Open Source Vive Tracker. It’s called the HiveTracker, and it …read more

Tiny Transmitter Tracks Targets

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
