The Perfect Tourist Techno-Cap

How many times are you out on vacation and neglect to take pictures to document it all for the folks back at home? Or maybe you forgot just exactly where that awesome waterfall was. [Mark Williams] has made a Raspberry Pi Zero enabled cap that can take photos and geotag them with the location as well as the attitude of the camera.

The idea is to enable the reconstruction of a trip photographically. The hardware consists of a Raspberry Pi Zero W coupled with a Raspberry Camera V2 and a BerryGPS-IMU. Once activated, the system starts taking photos every two …read more

Custom Data Writer Board For 1996 Plane’s GPS

[Dmitry Grinberg] recently bought a Cessna 150 that contained an old IFR-certified GPS from 1996, the KLN89B. The GPS unit contains a database which by law has to be kept up-to-date for IFR flight. The problem was that, while Honeywell still supplied the data in electronic form, [Dmitry] had no way to update the GPS. The original ways for doing it are either no longer supported, too expensive and a pain to do, or not available to him due to the way his GPS was installed.

Two of those ways involved removing a data card which can legally be slid …read more

Barely-There GSM GPS Tracker

What’s the most un-intrusive GPS you’ve ever seen? How about for a bike? Redditor [Fyodel] has built a Teensy-based GPS/GSM tracker that slides into your bike’s handlebars and really is out of sight.

The tracker operates on T-Mobile’s 2G service band — which will enable the device to work until about 2020 — since AT/T is phasing out their service come January. Since each positioning message averages 60 bytes, an IoT data plan is sufficient for moderate usage, with plans to switch over to a narrow-band LTE service when it becomes more affordable. [Fyodel] admits that battery life isn’t ideal …read more

MP3 Player and Handheld GPS is an Odd Combo Work Of Art

We think [Brek Martin] set out to build a handheld GPS and ended up adding an mp3 Player to it. Regardless, it’s beautifully constructed. Hand built circuit boards and even a custom antenna adorn this impressive build.

The core of the build is a 16 bit microcontroller a dsPIC33FJ128GP802 from Microchip. It’s a humble chip to be doing so much. It uses a UBlox NEO-6M positioning module for the location and a custom built QFH antenna built after calculations done with an online calculator for the GPS half. The audio half is based around a VLSI VS1003b decoder chip.

The …read more

Personal Compass Points to Your Spawn Point

A conventional compass points north (well, to magnetic north, anyway). [Videoschmideo]  wanted to make a compass that pointed somewhere specific. In particular, the compass — a wedding gift — was to point to a park where the newlywed couple got engaged. Like waking up in a fresh new Minecraft world, this is their spawn point and now they can always find their way back from the wilderness.

The device uses an Arduino, a GPS module, a compass, and a servo motor. Being a wedding gift, it also needs to meet certain aesthetic sensibilities. The device is in an attractive wooden …read more
