FPV Drone Takes Off From A Rocketing Start

May 15, 2025 by 24 Comments

Launching rockets into the sky can be a thrill, but why not make the fall just as interesting? That is exactly what [I Build Stuff] thought when attempting to build a self-landing payload. The idea is to release a can sized “satellite” from a rocket at an altitude upwards of 1 km, which will then fly back down to the launch point.

The device itself is a first-person view (FPV) drone running the popular Betaflight firmware. With arms that swing out with some of the smallest brushless motors you’ve ever seen (albeit not the smallest motor), the satellite is surprisingly capable. Unfortunately due to concerns over the legality of an autonomous payload, the drone is human controlled on the descent.

Using collaborated efforts, a successful launch was flown with the satellite making it to the ground unharmed, at least for the most part. While the device did show capabilities of being able to fly back, human error led to a manual recovery. Of course, this is far from the only rocketry hack we have seen here at Hackaday. If you are more into making the flight itself interesting, here is a record breaking one from USC students.

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.

Tiny Arduino Drone Even Has An FPV Camera

April 29, 2024 by 15 Comments

In the turmoil of today’s world, drones are getting bigger, badder, and angrier. [Max Imagination] has gone the other way with his work, though, building a teeny Arduino drone that can fit in the palm of your hand. Even if you have a small hand!

The drone is based around an Arduino Pro Mini, and uses an MPU6050 IMU for motion sensing and flight control. Communication with the drone is via an NRF24L01. Four small coreless motors are used for propulsion, driven by tiny MOSFETs, and the whole assembly is run via a teeny 220 mAh lithium-polymer battery. Oh, and there’s an FPV camera so you can put on some goggles and see where it’s going!

Control is via MultiWii software, written specifically for building multirotor craft. [Max] flies the craft using a controller of his own creation, again using an NRF24L01 for communication.

It’s a neat build, and a titchy one too! Tiny drones have a character all their own, even if they can’t really stand up to windier outdoor environments. Video after the break.

Got To Go Fast: The Rise Of Super-Fast FPV Drones

March 10, 2024 by 28 Comments

Generally when one considers quadcopter drones, the term ‘fast’ doesn’t come to mind, but with the rise of FPV  (First Person View) drones, they have increasingly been designed to go as fast as possible. This can be for competitive reasons, to dodge enemy fire on a battlefield, or in the case of [Luke Maximo Bell] to break the world speed record. Over the course of months he set out to design the fastest FPV drone, involving multiple prototypes, many test runs and one failed official speed run.

The basic design of these designed-for-speed FPV drones is more reminiscent of a rocket than a quadcopter, with the upside-down propellers  requiring the operator first lifting the drone into the air from an elevated position. After this the drone transitions into a level flight profile by rotating with the propellers pointing to the back. This gives the maximum thrust, while the body provides lift.

Although this seems simple, flying this type of drone is very hard, as it’s hard to tell what is happening, even when landing. [Luke] ended up installing a camera in the nose which can rotate to provide him with different angles. Tweaking the flight computer to deal with the control issues that occur at speeds above 300 km/h.

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?

Send This FPV Bot Into The Crawlspace To Do Your Dirty Work

April 18, 2023 by 27 Comments

The least pleasant space in most houses is likely to be the space below it. Basements tend to be dank, dusty, and full of too many things that have too many legs. And even worse than the full basement is the dreaded crawlspace, which adds claustrophobia to the long list of unpleasantries that lie below. Sadly, though, a crawlspace might be a handy place to run wires, and if you’re hesitant to delve too deeply, this FPV cable-laying rig might be something to keep in mind.

This one comes to us from [Old Alaska] with very little detail other than what’s in the brief video below. The setup is clear enough — a need to run an Ethernet cable from one side of the house to the other, and a crawlspace to do it in. Also in the toolkit was an RC rock crawler with a field-expedient FPV camera. With Breaking Bad-style access to the crawlspace through a few floorboards, [Old Alaska] was able to deploy the crawler dragging a Cat 5 cable behind it. The terrain under the house made the rock crawler a good choice, with four-wheel-drive, locking differentials, and an articulating frame. The bot’s-eye view also makes it clear that actually crawling in this rubble-strewn crawlspace would be a painful affair.

With very little drama, [Old Alaska] was able to navigate the crawler across the crawlspace to the outer wall of the house, where he could fish the wire out and complete the connection — no fuss, no muss, no bloody knees. The only quibble we’d have is not running an extra length of pull rope with the wire. You never know when it’ll come in handy.

The whole thing reminds us of a more tactical version of [Cliff Stoll]’s subterranean inventory management bot.
