2022 FPV Contest: A Poor Man’s Journey Into FPV

December 22, 2022 by Lewin Day 4 Comments

FPV can be a daunting hobby to get into. Screens, cameras, and other equipment can be expensive, and there’s a huge range of hardware to choose from. [JP Gleyzes] has been involved with RC vehicles for many years, and decided to leverage that experience to do FPV on a budget.

Early experiments involved building a headset on the cheap by using a smartphone combined with a set of simple headset magnifiers. With some simple modifications to off-the-shelf hardware, [JP] was able to build a serviceable headset with a smartphone serving as the display. Further work relied upon 3D printed blinds added on to a augmented-reality setup for even better results. [JP] also developed methods to use a joystick to fly a real RC aircraft. This was achieved by using an Android phone or ESP32 to interface with a joystick, and then spit out data to a board that produces PPM signals for broadcast by regular RC hardware.

[JP] put the rig to good use, using it to pilot a Parrot Disco flying wing drone. The result is a cheap method of flying FPV with added realism. The first-person view and realistic controls create a more authentic feeling of being “inside” the RC aircraft.

It goes to show that FPV rigs don’t have to break the bank if you’re willing to get creative. We’ve seen some great FPV cockpit builds before, too.

2022 FPV Contest: The LOTP Robot Dog

December 21, 2022 by Lewin Day 7 Comments

When you think of first person view (FPV) vehicles, aircraft might be what first comes to mind. However, [Limenitis Reducta] has brought a robot dog into the world, and plans to equip it for some FPV adventures.

LOTP pictured with various equippable modules.

The robot dog itself goes by the name of LOTP, for unspecified reasons, and was designed from the ground up in Fusion 360. A Teensy 3.5 is charged with running the show, managing control inputs and outputting the requisite instructions to the motor controllers to manage the walk cycle. Movement are issued via a custom RC controller. Thanks to an onboard IMU, the robotic platform is able to walk effectively and maintain its balance even on a sloping or moving platform.

[Limenitis] has built the robot with a modular platform to support different duties. Equitable modules include a sensor for detecting dangerous gases, a drone launching platform, and a lidar module. There’s also a provision for a camera which sends live video to the remote controller. [Limenitis] has that implemented with what appears to be a regular drone FPV camera, a straightforward way to get the job done.

It’s a fun build that looks ready to scamper around on adventures outside. Doing so with an FPV camera certainly looks fun, and we’ve seen similar gear equipped on other robot dogs, too.

Start Your Engines: The FPV Contest Begins Now!

November 22, 2022 by Elliot Williams 15 Comments

There are places that you can go in person, but for everything else, there’s FPV. Whether you’re flying race quads, diving the depths in a yellow submarine, or simply roving the surface of the land, we want to see your builds. If it’s remote controlled, and you feel like you’re in the pilot’s seat, it’s FPV.

When you say “first person view” many of you will instinctively follow up with “flight” or “drone”. But given the ease of adding a camera and remote control to almost any vehicle, there’s no reason to only fly the FPV skies. (Of course, we want to see your crazy quadcopter builds too.)

We went looking for a few less-traditional examples to whet your appetite, and we found a lot. There are super-cute FPV bots for indoors and more robust tanks for cruising around the neighborhood. In the summer, you’ll probably need an FPV lawnmower, and for the winter, naturally, an FPV snowblower or a budget-friendly FPV snow-boat. Or skip the outdoors entirely and terrorize the pool with an FPV sub.

This contest isn’t exclusively about the vehicles either. If you’re working on the tech that makes FPV possible, we want you to enter. For instance, this simple quad/drone tracker will help keep your video feed running and your mind on flying. This cockpit will make the immersion more complete. And nobody likes the jello-cam effect that excess vibration can cause, so we’d like to see camera hacks as well.

And of course, your quads. Is your FPV quad too fast, too light, or does it fly too far? Show us. The contest starts now and runs until Jan 3, 2023, and there are three $150 shopping sprees courtesy of Digi-Key on the line. Get hacking!

2022 Cyberdeck Contest: Prototype Cyberdeck Is Anything But Questionable

October 26, 2022 by Jenny List 5 Comments

We see many projects here at Hackaday, about which their creators are unreasonably modest. We like a good cyberdeck, and we think [betaraybiff] is one of those creators from their project description for a Prototype Cyberdeck of Questionable Practical Use. It may be a prototype, but we think it could be quite a practical computer.

At its heart is the ubiquitous Raspberry Pi 4 paired with a PiSugar power supply and a minimalist mechanical keyboard. The case is the interesting part, because it’s well-designed to be 3D printed in sections with the HDMI display hinging up from above the keyboard. The Pi is open and visible on top of the deck, but this could easily be covered with another printed piece if desired.

So we disagree on the practicality, given a train journey and this cyberdeck we think we could easily crack out a Hackaday article or two. Never undersell your creations, like this one they’re almost certainly better than you think.

Cyberdeck Contest 2022: Gibson Rev 001 Thinks Outside The Pelican Case

October 25, 2022 by Kristina Panos 5 Comments

As we’ve gushed previously in these pages, we saw an incredible turnout for our first-ever cyberdeck contest — so many cool ‘decks rolled in that it made judging them all quite the feat, and we would be remiss if we didn’t feature the favorites that, for whatever reason, didn’t make the cut. One of these is the aptly-named Gibson Rev 001 from [Gadjet].

This cyberdeck may be on the pocket-sized side of things, but don’t let that fool you, because it’s loaded with I/O and sensors galore. A Pimoroni Breakout Garden provides particle/smoke and pulse oximetry, temperature/pressure/altitude, an air quality sensor, and a UVA/UVB light sensor — plenty of feelers for judging conditions on the fly. As you might expect, the brains of the operation is a Raspi 4, which is running Twister OS.

We love the dual-display thing going on with the 7″ touchscreen and the color e-ink display — really gives it a cobbled-together-yet-polished, futuristic feel. May the rest of the post-apocalypse gadgetry have such clean lines and cheerful colors (if that’s what you’re into).

2022 Cyberdeck Contest: QAZ Personal Terminal

October 22, 2022 by Navarre Bartz 9 Comments

The slabtop form factor has had a resurgence in the cyberdeck community, and [Greg Leo] has designed the QAZ Personal Terminal to be about as small as a slabtop could be while still having full-sized keys.

Since the device is using a 35% QAZ keyboard as its primary input device, [Leo] has helpfully given a quick overview of how text is input in the video below. Coupled with that surprisingly popular 4:1 LCD screen we’ve seen elsewhere, this cyberdeck looks like a modern interpretation of a TRS-80 Model 100. The Banana Pi powering the QAZ Personal Terminal is running Debian with spectrwm, a tiling window manager making arranging windows a breeze with either a mouse or keyboard. The integrated mouse layer on the keyboard means you don’t need a separate mouse at all if you don’t want to spoil the 1980s mobile chic.

[Leo] has another video all about doing calculus on this cyberdeck with the math shortcuts integrated into the keyboard. Fractions, exponents, and common Greek letters are demonstrated. We can see this being a really great note-taking device for engineering and math courses if you wanted something more portable than a laptop.

It’s hard to get very far hacking without a little math. For more math-focused input devices, check out the Mathboard or the MCM/70.

2022 Cyberdeck Contest: Keezyboost40 Is A Cyberdeck Masquerading As A Keyboard

October 20, 2022 by Navarre Bartz 5 Comments

There’s something to be said for über-powerful cyberdecks, but there’s also a certain appeal to less powerful decks squeezed into a tiny form factor. [Christian Lo] has designed a cyberdeck that looks like a simple ortholinear keyboard but is running a more flexible environment.

There are games and animations you can play on QMK, but [Lo] felt that a different framework would give him more flexibility to really stretch the limits of what this Raspberry Pi Pico-powered deck could do. He decided to go with a Rust-based firmware with the keyberon library and says, “it felt like I was in control of the firmware.” While the board is using Rust for now, [Lo] says he’s open to conversations about other firmware options to achieve his goals, like a virtual pet game for the board.

The PCB is described as “bog standard” with the possible exception of placing the Pi in a cutout on the board to keep things as low profile as possible. The trade-off comes in the form of reduced board rigidity and potentially increased strain on the connections to the microcontroller.
