The “Navigation Thing“ was designed and built by [Jan Mrázek] as part of a night game activity for high school students during week-long seminar. A night-time path through a forest had stations with simple tasks, and the Navigation Thing used GPS, digital compass, a beeper, and a ring of RGB LEDs to provide a bit of “Wow factor” while guiding a group of students from one station to the next. The devices had a clear design direction:
“I wanted to build a device which a participant would find, insert batteries, and follow the beeping to find the next stop. Imagine the strong feeling of straying in the middle of the night in an unknown terrain far away from civilization trusting only a beeping thing you found. That was the feeling I wanted to achieve.”
The Navigation Things (there are six in total) guide users to fixed waypoints with GPS, a digital compass, and a ring of WS2812 LEDs — but the primary means of feedback to the user is a beeping that gets faster as you approach the destination. [Jan] had only four days to make all six units, which was doable. But as most of us know, delivering on a tight deadline is often less about doing the work you know about, and more about effectively handling the unexpected obstacles that inevitably pop up in the process.

[TJ Hunter] wanted to find some of the rarer Pokémon without draining his smartphone battery while staring on a screen. The handy ø 25 cm Pokéball he built to make the endless marches more tolerable detects nearby Pokémon and wiggles to alert its owner if there’s a rare catch in sight.

We’re not sure if [Derek Lieber] is messing with us or proving a point. Why are you doing this [Derek]? We know there’s technically enough information to build the clock. You even included the code. Couldn’t you have at least thrown in a couple of words? Do we have to skip straight to mediaglyphics?
Anyway, if we follow the equation. The equation… If you take a gps module, a 7 segment display with an HT16K33 backpack, a digital potentiometer, a piezo, and a boarduino we suppose we could grudgingly admit that these would all fit together to make a clock. We still don’t like it though, but we’ll admit that the nice handmade case was a nice touch, and that the pictures do give us enough details to do it ourselves.
It was also pretty cool when you added the Zelda theme song as an alarm sound. Also pretty neat that, being GPS corrected, there’s no need to ever set the time. We may also like the simplicity of the only inputs being the potentiometer, which is used to set the alarm time. It’s just. Dangit [Derek]. Nice clock build, we like it.
[Pepijn de Vos] was excited to interact with the world’s most popular augmented reality pedometer, Pokemon Go, and was extremely disappointed to find that his Blackberry couldn’t run it. Still, as far as he could tell from behind his wall of obsolete technology, Pokemon Go is all about walking distractedly, being suspicious, and occasionally catching a Pokemon. That should be possible.
Not a stranger to hacking Pokemon on the Gameboy, [Pepijn] put together a plan. Using his TCPoke module, he took it a step further. Rather than just emulating the original gameboy trade signals over the internet, he hacked a Pokemon Red ROM with some custom Z80 assembly to add some features to the Cable Club in the game.
After some waiting for the delivery man to bring a flashable cartridge and along with some Arduino code, he could now translate the steps he took in the game to his steps in the real world. Well, mostly. He could pick the location where he would like to catch a Pokemon. The character stands there. Somewhere around 100m the game will trigger a random pokemon battle.
[Pepijn] is now no longer a social outcast, as you can see in the video after the break. On a simple trip to the grocery store he caught two Pokemon!

Using Xcode to spoof GPS locations in Pokemon Go (like we saw this morning) isn’t that much of a hack, and frankly, it’s not even a legit GPS spoof. After all, it’s not like we’re using an SDR to spoof the physical GPS signal to cheat Pokemon Go.
To [Stefan Kiese], this isn’t much more than an exercise. He’s not even playing Pokemon Go. To squeeze a usable GPS signal out of his HackRF One, a $300 Software Defined Radio, [Stefan] uses an external precision clock. This makes up for the insufficient calibration of the HackRF’s internal clock, although he points out that this might also be fixed entirely in software.

Pokemon Go inherits a certain vulnerability to GPS location spoofing from it’s predecessor Ingress, but also the progress that has been made in spoof detection. Since taking advantage of a game’s underlying mechanisms is part of the winner’s game, why not hook up your smartphone to Xcode and see if you can beat Niantic this time? [Dave Conroy] shows you how to play back waypoints and activate your Pokemon Go warp drive.

Several years ago, Iran used GPS spoofing to ‘land’ an RQ-170 Sentinel drone operated by the US military. Why is this interesting now? Because this week Pokemon GO was released. It’s a mobile, augmented-reality game that forces you to walk around your neighborhood to catch Pokemon. Apparently you can capture a Mewtwo if you make it to Area 51, Groudon near any volcano, and Deoxys is aboard the International Space Station. In the next week or two, someone will figure out how to spoof the GPS location on a phone to catch rare and legendary Pokemon. This will happen.
The FR4 Machine Shield is a CNC kit made from a PCB. Yes, the entire machine can be constructed using a panel from a board house. It’s now a Kickstarter. Like other desktop PCB milling machines, the FR4 uses hobby brushless motors (think quadcopters) for the spindle, and features tab and slot construction. It’s a pretty neat little tool we checked out a little while ago
There’s a lot going on during the first weekend in August. We’re going to DEF CON, I’m trying to rope a few writers into going to the Vintage Computer Festival West, and Electromagnetic Field Camp is happening in the UK. Hackaday will have a contingent at EMF Camp, so be sure to tell us if you’re going and we’ll bring some stickers
If you ride a bicycle, you have a hand pump somewhere around. Those hand pumps get pretty tiring. Here’s a much better solution. It’s a pneumatic air pump. It will inflate your bike tire with the power of compressed air. But that’s not all… this device will also inflate basketballs, soccer balls, and footballs, all with a simple and easy to use air compressor.
The Hackaday logo was one of the first things on Thingiverse, but surprisingly there aren’t many jolly wrenchers plastered onto 3D prints. To fix this glaring oversight by everyone, [Tom] whipped up the Hackaday logo in OpenSCAD.
[Blecky] is building a local positioning system for his entry into this year’s Hackaday Prize. Now it’s a Kickstarter. As a new feature, a pair of these boards can also do motion detection
