Hackaday Supercon - HunterScott : Why Phased Arrays are Cool and How to Build One

[@Unmanned-Technologies]

this was enjoyable to watch. And yeah, RF is mostly figuring out why things don't work :)

[@midnightman011]

These talks and presentations are nice Hackaday .. thanks for your hard work

[@DanielLopez-up6os]

Scott Explained everything so well.

[@AndrewJones-tj6et]

That's an awesome presentation on this topic by Hunter. I can appreciate some of the rabbit holes he has probably gone down with this stuff.

[@sergarlantyrell7847]

I have been thinking about this for YEARS and I'm glad to hear I wasn't THAT far off in my napkin designs considering RF design is completely new to me. It's definitely going on the "How hard can it be?" list of DIY projects I plan to do within the next several years.

[@forloop7713]

Have you completed some hard projects before?

[@jafinch78]

This looks really awesome. I just realized when I've been using the term passive phased array... I've been wrong. For my system I was only planning on receive mode only to maintain more radio silence. Then interpreting and interpolating the data based on phased received on each antenna as well as other characteristic. This has been a great presentation and I appreciate the detail! Really cool how the microwave systems are like RF erector sets almost. I think there is an area of opportunity to bring this down to the not as budget liquid hackers. Reminds me of machine tools for watches more now with modern microscopes and CNC's, even if using rotary controllers, to aid in construction details. Maybe have extra material on the initial PCB runs to trim later for tuning? Looking forward to seeing this project move forward.

Great presentation straight to the point - love the style

While f16 have panning radar, I think, f15 does have phased array radar.

[@TealJosh]

f16 is old fighter and was overtaken by f22 for the most part. F15 is still in extensive usage by US air force, which means they have updated it a lot.

[@shinjithenegotiator2795]

@@TealJosh the upgraded f16 has an AESA which is a form of phased array radar

[@TealJosh]

​@@shinjithenegotiator2795 indeed, in fact US air force placed an order to extend f16 lifetime to 40s and that includes whole fleet getting AESA radar. Makes sense considering F22 fleet is tiny.

[@forloop7713]

He has an in depth understanding

What's the chip you mention at the end?

[@skyebedard2148]

Sorry for responding to this ~2 years later, but I think I might know. Given his description, it sounds like the ADAR lineup from Analog Devices. My senior design team is using 4 ADAR1000's for our phased array. 4 channels each (Rx, Tx, and power detector) with amplitude/phase control for each channel all for the low, low price of $995 per eval board. I imagine the chip is cheaper but we didn't get a quote for that because we already have enough work without fabricating our own boards with 88 pin QFN packages. That being said, I definitely want to try working with raw chips in the future.

[@shirishjadav1462]

Thats a brillient stuff. Well I am looking for resource where I want to find AoA of BLE beacons. I Know Nordic has done it but I want to do without RF just multiple NRF51,NRF52 chips detecting same mac address and get to know the delta between both receiving same mac. I want to know from people if even if its possible to do so ?

[@charlesmartin1972]

If you're just phase shifting the carrier wave, wouldn't a data signal get distorted for directions far from the normal vector? I think to get a crisp steerable-directional 5g signal onto a dongle, you'd have to find a way to condense a bunch of RF delay elements onto a printed circuit. I think it can be done, but yikes Ambitious project. A+. Cheering for you from the sidelines

[@terence79chan]

Check out my affordable phase shifting array antenna for 5.8ghz (just search for Beam Steering FPV in YT)... it is hard work but definitely possible to achieve descent beam-steering at 5ghz which I used it for tracking my drone’s video signal.

[@straat9066]

So could I make a 38 Ghz antenna with 6 6.4ghz antennas?

[@transkryption]

3:20 Smoked wheee!....watching those animations and wooow.., He's explaining what I'd always wondered, this is no art o' multiple coathangers/cantennas strung togwther. I get it man! ... If I'd dropped acid or smoked weed and watched this at 14, I would have a PhD in physics and be a billionaire.

[@timonsku]

All these Supercon videos are unfortunately badly leveled, they are all super silent always have to turn up the volume to 100% :(

[@OktoPutsch]

It's called mumble-scrambling, a new obfuscation technique.

[@Aemilindore]

@@OktoPutsch can you explain?

[@charlesalexanderable]

They need to use phased array mics

[@edgeeffect]

Mentioning that "phased arrays" are a kind of antenna and that this is RF stuff in the title or description would have saved me (okay, only) 2 minutes.....

[@DBuilder1977]

I would like to comment on this video but we don't have time for this

Hey be careful you dont fry your brain or someone else's brain.
