FPV Flying In Mixed Reality Is Easier Than You’d Think

January 3, 2025 by 12 Comments

Flying a first-person view (FPV) remote controlled aircraft with goggles is an immersive experience that makes you feel as if you’re really sitting in the cockpit of the plane or quadcopter. Unfortunately, while your wearing the goggles, you’re also completely blind to the world around you. That’s why you’re supposed to have a spotter nearby to keep watch on the local meatspace while you’re looping through the air.

But what if you could have the best of both worlds? What if your goggles not only allowed you to see the video stream from your craft’s FPV camera, but you could also see the world around you. That’s precisely the idea behind mixed reality goggles such as Apple Vision Pro and Meta’s Quest, you just need to put all the pieces together. In a recent video [Hoarder Sam] shows you exactly how to pull it off, and we have to say, the results look quite compelling.

DIYFPV: A New Home For Drone Builders

January 2, 2025 by 30 Comments

If you’re looking to get into flying first-person view (FPV) remote controlled aircraft, there’s an incredible amount of information available online. Seriously, it’s ridiculous. In fact, between the different forums and the countless YouTube videos out there, it can be difficult to sort through the noise and actually find the information you need.

What if there was one location where FPV folks could look up hardware, compare notes, and maybe even meet up for the occasional flight? That’s the idea behind the recently launched DIYFPV. In its current state the website is a cross between a social media platform, a hardware database, and a tech support forum.

Being able to look up parts to see who has them in stock and for what price is certainly handy, and is likely to become a very valuable resource, especially as users start filling the database with first-hand reviews. There’s no shortage of social media platforms where you can post and chat about FPV, but pairing that with a dedicated tech support section has promise. Especially if the solutions it produces start getting scrapped by show up in search engines.

But the part of DIYFPV that has us the most interested is the interactive builder tool. As explained in the announcement video below, once this feature goes live, it will allow users to pick parts from the database and virtually wire them together. Parts are represented by high-quality illustrations that accurately represent connectors and solder pads, so you won’t be left guessing where you’re supposed to connect what. Schematics can be shared with others to help with troubleshooting or if you want to get feedback.

The potential here is immense. Imagine a function to estimate the mass of the currently selected electronics, or a simulation of how much current it will draw during flight. It’s not clear how far DIYFPV plans on taking this feature, but we’re eager to find out.

Trying To Shatter The World’s Fastest RC Car Record

Fresh off a world record for the fastest quadcopter, [Luke Bell] decided to try his luck with something more own to earth, namely trying to tackle the world record for the fastest RC car, with the current record set at 360 km/h. Starting off with a first attempt in what will be a video series, the obvious approach seems to be to get some really powerful electric motors, a streamlined body and a disused runway to send said RC car hurtling along towards that golden medal. Of course, if it was that easy, others would have done it already.

With the quadcopter record of nearly 500 km/h which we covered previously, the challenge was in a way easier, as other than air resistance and accidental lithobraking there are no worries about ground texture, tire wear or boundary layer aerodynamics. In comparison, the RC car has to contend with all of these, with the runway’s rough tarmac surface being just one of the issues, along with making sure that the wheels would hold up to the required rotation speed. For the wheels you got options like foam, hard rubber, etc., all with their own advantages and disadvantages, mostly in terms of grip and reliability.

So far speeds of over 200 km/h are easy enough to do, with foam wheels being the preferred option. To push the RC car to 300 km/h and beyond, a lot more experimentation and trial runs will have to be performed. Pending are changes to the aerodynamic design with features also commonly seen in F1 race cars such as downforce spoilers, diffusers and other tricks which should prevent the RC car from (briefly) becoming an RC airplane.

Flaming Power Wheels Skeleton Wins Halloween

November 5, 2024 by 48 Comments

When the project description starts with the sentence “I use an RC remote and receiver, an esp32, high-current motor drivers, servos, an FPV camera, and a little propane”, you know that this is one which deserves a second look. And so [gearscodeandfire]’s Halloween project caught our eye. It’s a pink Power Wheels jeep driven by a skeletal rider, and the best part is that the whole thing is remote controlled down to a pan-and-tilt skull, a first-person video feed, and even real flames.

At its heart is an ESP32 with a set of motor controllers and relays to do the heavy lifting. The controller is a standard radio remote controller, and the first-person view is an analogue feed as you’d find on a drone. The skeleton is given a child-like appearance by discarding the original adult-proportioned plastic skull and replacing it with a much larger item. The thought that plastic Halloween skulls are available in a range of standard sizes and can be considered as a part in their own right is something we find amusing. The propane burner is supplied from a small cylinder via a solenoid valve, and ignited with the spark from a high-voltage transformer.

The result, we think, wins Halloween hands down. Twelve-foot skeletons are SO 2023!

The video is below the break.

Pi Zero FPV Robot Uses Tiny Motor & Gears

November 14, 2023 by 4 Comments

We’ve seen plenty of first-person view (FPV) robots built using the Raspberry Pi Zero, but this one from [Shane] has an interesting twist: rather than directly driving the wheels from big motors, it uses small motors and gearboxes to drive the wheels, with some of the gears being 3D printed.

[Shane] has posted the full details of this cute little robot, complete with 3D models, code, and plans for the PCB that connects the Zero to the motors. These motors are N20 ones, which are much smaller and cheaper than what we usually see used in these projects, and run faster. They also often come with a gearbox that reduces the speed to something a bit more useful. Each motor drives the two wheels on one side through a 3D printed gear for tank-style steering.

To run the whole thing off a single LiPo battery, [Shane] also designed his own Pi Hat that converted the voltage to 5 V and added a couple of H bridge chips for the motors. It is a cute little build, but the requirement for a custom Pi hat perhaps puts it beyond most beginners, who might be interested in a cheap, straightforward build like this. Does anybody have any alternatives?

Hot Wheel Car Becomes 1/64 Scale Micro RC Car, Complete With Camera

November 13, 2023 by 20 Comments

If you enjoy watching skilled assembly of small mechanical systems with electronics to match, then make some time to watch [Max Imagination] transform a Hot Wheels car into a 1/64th scale RC car complete with video FPV video feed. To say the project took careful planning and assembly would be an understatement, and the results look great.

The sort of affordable electronics available to hobbyists today opens up all kinds of possibilities, but connecting up various integrated modules brings its own challenges. This is especially true when there are physical constraints such as fitting everything into an off-the-shelf 1/64 scale toy car.

There are a lot of interesting build details that [Max] showcases, such as rebuilding a tiny DC motor to have a longer shaft so that it can drive both wheels at once. We also liked the use of 0.2 mm thick nickel strips (intended for connecting cells in a battery pack) as compliant structural components.

There are actually two web servers being run on the car. One provides an interface for throttle and steering (here’s the code it uses), and the other takes care of the video feed with ESP32-CAM sending a motion jpeg stream. [Max]’s mobile phone is used to control the car, and a second device goes into an old phone-based VR headset to display the FPV video feed.

Circuit diagrams and code are available for anyone wanting to perhaps make a similar project. We’ve seen micro RC builds of high quality before, but integrating an FPV camera kicks things up a notch. Want even more complex builds? All the rules change when weight reduction is a non-negotiable #1 priority. Check out a micro RC plane that weighs under three grams and get a few new ideas.

2022 FPV Contest: Congratulations To The Winners!

January 16, 2023 by 6 Comments

We wanted to see what the Hackaday crowd was up to in first-person view tech, and you didn’t disappoint! Commercial FPV quads have become cheap enough these days that everyone and their mom got one for Christmas, so it was fantastic to see the DIY spirit in these projects. Thanks to everyone who entered.

The Winners

None of the entries do the DIY quite as thoroughly as [JP Gleyzes]’s “poor man’s FPV journey”. This is actually three hacks in one, with DIY FPV goggles made from cheap optics and 3D printed additions, a USB joystick to PPM adapter to use arbitrary controllers with an RC transmitter, and even a fully DIY Bluetooth-based controller for a popular flight simulator. [JP] has done everything but build his own drone, and all the files are there for you to use, whether you’re goal is to do it on the cheap, or to do something new.

If you want to build your own drone from scratch, though, ESP32 Drone project has you covered. At least, mostly. This build isn’t entirely finished yet, and it’s definitely got some crash-testing still in its future, but the scope and accessibility of the project is what caught our eyes. The goal is to make a lightweight indoor quad around parts we can all get easily and cheaply, completely scratch-built. This drone is meant to be controlled by a smartphone, and the coolest parts for us are the ESP_Drone and ESPStream software that run on the drone and your phone respectively. Congrats to [Jon VB]! Now get that thing in the air.

And if you’re looking for a tidy little build, [Tobias]’s Mini FPV Speed Tank doesn’t disappoint. It’s a palm-sized mini tank, but this thing hauls, and looks like a ton of fun to drive around. It uses an absolutely tiny RP2040 module, an equally tiny receiver, and a nano FPV camera and transmitter to keep it compact. The 3D-printed frame and tracks are so nice that we’re not even complaining that the FPV rig is simply rubber-banded on top of the battery. This looks like a super fun build.

Each of these three projects have won a $150 Digi-Key shopping spree to help out with parts in this, or your next project. Thanks again to Digi-Key for sponsoring!
