Odd, it's just fine for me on firefox/ublock origin.

I played with €25 foldable wifi drone from Lidl until EU started requiring €30 fee annual for a camera drone. I cannot think much practical use for drone without a camera. Fly-fishing might be one, but I need to program it so that it drops the line and returns home the moment it feels fish yanking.

Drone reg here in Ireland (over 250g or with a camera its required) €38 for two years.

This is amazing. Even the landing gear (struts?) is part of the PCB. I hope the author considers selling kits or outsourcing kits to SeedStudio. I live in a country where digikey order shipping is quite pricey. The author estimates the BOM to be a little under US$13. At that price it would be fun to try create a swarm for DIY drone lights show. [1] https://circuitdigest.com/microcontroller-projects/DIY-wifi-...

FWIW, making just 10 might drive that $13 price down quite a bit. Although, it looks like 1 unit might be closer to $50 (at least for the suppliers I might use), but $150 for 10. I think costs could be cut somewhat though. The USB->serial chip is nearly $6, but differently packaged it can be $4.40 for 1 or $3.99/ea for 10, and alternative chips that seem like they should be good enough can be cheaper still. The volta…

If you're making lots, you could uncouple the programming interface which isn't needed while in flight, thereby saving both BOM and weight.

Or if you don't want to do it from scratch, you can get a programmable readymade for a little more: https://shop.m5stack.com/products/m5stamp-fly-with-m5stamps3... The included software stack is very basic, dig around on Japanese nerd Twitter for open source avionics.

Right, but it's 3x the price and out of stock :(

What a great time for this article! The US is having a mass hysteria event and it turns out you can churn out DYI drones for the fat sum of $12-13 each? What a time to be alive! Edit: Hmm, considering that people are taking stars for UFOs lately, maybe a cheap drone is an overkill and a 20-pack of Chinese sky lanterns would be more than enough to keep the average US neighbourhood in a state of constant fear / see how…

The interesting/scary part is that its not that hard to weaponise these drones. You can make one drop a home made explosive pretty easily, fully autonomous. and then dump itself into a body of water. All for way less cost than a gun.

Welcome to hacker News! Yes, we find ignorance funny. I think people adding fuel to the fire are the ones freaking out about aliens or Iranian mother ships. Pointing out that the this is a hysteria event is more akin to pouring water on the flames.

No, it is not "Hacker News" to paint a large swath of people as "ignorant". The proper way would have been to publish a detailed, technical analysis and present your ideas along with your proof to the greater community and facilitate a discussion.

I want to live in this world, where we're all part of a larger collective endeavor to discover the truth, to be more informed, learn continuously, and evolve together. That's the old-school philosophy and mission of science for the betterment of humanity.

There’s a small link at the bottom to “Add all DigiKey Parts to Cart.” But one of the parts is apparently already obsolete and unavailable, and two more have minimum quantities above what’s needed here, so it’s not great.

But one of the parts is apparently already obsolete and unavailable I love Digikey, but unfortunately this is not uncommon at all.

Fun. I'm looking into turning my old iPhone into a drone as it has great hardware already to do higher level tasks and use ESP32 for the more real time stuff like actually driving the motors based on sensor input.

If you think about it, an old iPhone 6 comes with GPS, gyro, accelerometer, multiple cameras, pretty powerful processors, bluetooth + wifi + LTE, sound + light, ambient + proximity sensors. Get rid of the case, and you have a great mini computer that can be aware of its surroundings and communicate.

On more modern iPhones, you can even use advanced tech like ARKit to have great spatial understanding of your drone and environment and do autonomous drones. With an iPhone 15, you can even get spatial video. How amazing would that be?

I wish Apple provided a straightforward way to unlock(like remove restrictions on the OS level) old phones and use them for DIY projects.

I'm also using firefox/ublock but I'm getting the mentioned agressively-blocked page. I'm also using a VPN, if that makes any difference.

I also see the extremely light "Press & Hold" message to prove I am not a bot. I missed it the first few times I loaded the page because my eyes just don't pick up on things like that very easily (I'm the guy who turns the brightness up in video games with a lot of shadow). Not only does this press & hold action seem to be ineffective, but they made a message that some humans have trouble seem to keep bots out? Smdh.

Which is disappointing, because I've ordered from digikey countless times, both for work and for personal projects. There should be absolutely no reason they clamp down on people using adblockers since they are highly profitable already. Guess I'll be looking for a different parts source.
