Some S-Band Experiments & Quick Look At The HackRF One! 

"I have lots of failures on my channel" -> Excellent! Best way to learn. Not just for you, but also for your viewers. I like genuine, unfiltered documentation of experiments.

This channel alone completely destroys the flat earth conspiracy.

Thank you, Fluff, for helping to properly incubate the antennas.

From sand caves, gas powered headlamps to satellites, all the projects and content have been awesome!

You just aren't editing out your failures, like most other channels. It is why I absolutely love your channel, it's how learning actually works! Thanks for sharing all the stuff!

I haven't seen _any_ failures here. I'm simply seeing life.

Donny is my favorite regular guest.

"I have lots of failures on my channel". This is the mark of a passionate hobbyist and future maestro. Keep hackin!!!

Your awesome experiments aren't failures. Bob Ross has taught us they're happy lil accidents. Plus I'm starting to draw a happy connection between your experiments and certain satellites lately, suffering a rapid disassembly in space and that's so much fun!! 😆👍

Failures or not, it's always good watching you having fun. Thanks for showing us :) And I like watching the cats help out.

Such good cats, always being helpful 3:55 GOOSE!

This channel has all my favorite failure modes! I learn *_so much_* just by proxy 😁

Love your Allen mythbusters shirt.

The guy deserves all the likes on RU-vid

You definitely have two adorable little helpers(solicitors)

Gotta hand it to you Gabe; you have way more patience than I do! You will pick up those S band sats eventually!

i love to see failures, experiments and messing about - that's what makes it fun and genuine. for me, filtered and edited content is overwhelming and sometimes depressing. i'm a programmer, i can't relate to things just working out

By posting failures and getting comments from people, that's the best way to run a channel, to be interactive, so that people can make suggestions. Some suggestions may not be relevant, but they might inspire another thought which may eventually lead to a breakthrough.

Lol they're some curious kitties. Love these vids 👏👏😻

Mate, so many of us out here doing all the same stuff. Keep it up bro!

Echoing the others re: getting a better printer. I used to have that exact mono price printer and upgraded to an ENDER 3 v2, night and day difference! But recently I’ve started looking into a Bambu labs printer. Orders of magnitude faster, more reliable, and silent!

I used to have the same 3D printer as you and could never get any good results😅 Upgraded to a better printer and it's like heaven, it just works. I really love your channel and I also like to decode satellites.

Gabe, you rack this up as a failure, but you are light years ahead the crowd. Through your mistakes and trials and errors, we are learning a lot from you. Thank you! =)

HackRF 😮😮 Another banger vid exploring the S band

My Proof-of-Concept S-band feed for the big dish uses a pair of LaNA amplifiers, because they're relatively cheap. I'm using a circular wave-guide feed, with two orthogonal linear feed probes. Haven't had an opportunity to put it at the feed point yet, but maybe once the summer-camp stuff is done...Plus, well, I really *hate* climbing the scaffolding we use to access the feed-point. In the spirit of "save it for parts", the circular waveguide is a chunk of 4" aluminum heavy-wall tubing that was originally a hybrid rocket motor casing from a prototype hybrid motor product I was working on about 18 years ago. Gulp. That's a lot of years ago now. At least it got reused for a noble purpose, instead of you know, being turned into a bong or something :)

i dont mind if your channel turns into a doomsday tech-prepper, what you share here is always golden. keep it up man.

cat hair makes everything better. 😻

Nice shirt. Excellent depiction.👍

Love the channel, all the videos and your shirt is amazing!!!

You absolutely need a LNA at the feed antena, then the downconverter. The down converter alone have 10db loss, and the cable and connections add a bit more. The nooelec LANA is very good and you already have one. I used that LNA to decode ham radio signals from the moon (EME) and it performance is very good.

Great video as always.

Great video 👍 ok so it didn't work, but you always make the journey fun and interesting 😉 thank you 🏆

So glad you got one of those things. I found one used for $100 and jumped on it. Shortwave to satellites with all the interesting bits between. Should be a good content generator.

England tuned in thanking you

Hooray for Donny and Fluff -- the Sat Cats!

I have the jack rf one sdr. Turn on and off the settings at the top. Bias I think removes the artefact. Also, They blow the input transistors for the rf amp. Disconnect the antenna as local lightning or transmitters will blow it.

Dude you gotta get a new printer. I just bought a bambu labs A1 mini for freakin 200$! They're on sale and you should really pick one up. Ive never had a machine that just works anytime you go to use it. No adjusting infinite different things trying to troubleshoot a failed print. It just WORKS and its FAST as hell. Glad to see you finally got yourself a hackrf cheers

Love this. And thanks for plugging dereksgc - another awesome RU-vidr. Both of your channels are continuous inspirations to me (and I am sure lots of others) to try, fail, and keep at it, because it isn't about some random bs 'success'. It is about always trying to do more cool shit, just because it is cool. And please never worry about 'losing' subscribers to anyone else. This isn't a zero-sum game. The more of us that are in the 'trying cool shit' game, the more we all win. Cheers!

Technically, the exmas tree is a Log Periodic Dipole Array, or LPDA.

Brother, Please run gcode validation routine on your 3d printer file. Its VERY possible that you have a bad file. You shouldn't have spagettified prints unless the project code is bad. Try looking at the STL file in a viewer. Keep up the great work and know that we appreciate your diligence.

I personally own a ham it down along with my rtl sdr v3. I do like it, when I get my hands on a dish I might do some S band experimentation. I have been looking at the hackrf, very pricey like you said, but it's capabilities impress me.

I haven't dared to tackle the S-band yet, it's nice that they are sharing their experiences. Maybe their successes will ease my fear of the S-band. With the HackRF One, you can also transmit, so I'm curious about that.

i LOVE that Mythbusters T-Shirt!

A clothespin would be great to hold and switch out those antennas.

I have had an HackRF with Mayhem software for a few months but haven't had much time to mess with it. I copied all my key fobs since they are older and don't use rolling codes. Never know when the keys may get locked in the car. Looking forward to the videos.

HackRF One's are awesome bro. Glad you got one. I've had one for a couple years now. Love it for receiving. Any sort of useful transmitting will require amplifiers.

You may need to manage the humidity on your printer spools. I keep mine sealed in a desiccant box, but you can also just toss in a toaster oven set at lowest setting to draw out that moisture.

The larger the dish the narrower the beam. That means it maybe tricky to point. Keep up the good work.

On those tall prints I have issues as well. Not sure it would help with that, but I am getting a self leveler for the bed on mine.I think it will help it live longer due to less rage.

love the cats

I am sure the HackRF-One is a very nice rig or SDR. Maybe someday on my list.... I myself have the SDRPlay RSP-1A as strictly a receiver and RS-918 as a transceiver. At the time I bought the RSP-1A the cost was $100. Now its a tiny bit more & they have units with even better signal to noise ratios as well as multi receiver units. I forget what my RSP-1A ranges to. Either 2 or 3 GHz. The receiver & transceiver is normally in HF land. I do have the Rohde & Schwarz worldwide spectrum allocations poster & noticed after S band comes C, X, Ku, K, Ka, V, W, & lastly G band at 300 GHz. Plenty to test out down the road although at 300 GHz you might need tweezers for picking up the associated antenna. Have fun...

You should make more videos about boats made from satellite dishes.

Spaghetti like that on the build plate, can often be fixed by re-leveling the bed and adding more glue stick on the build plate. Keen to see what you come up with next!

Love the Jamie H Tee haha

Your "this plant has worked..." sign needs an arrow pointing to a v. small pot plant

S-Band lets gooooooooo

For the 3d printing, your filament seems to be extremely wet, notice the bubble like pops on the print itself. If you can get a dry box or dehydrate your filament. Also the filament seen here seems like its beyond saving at this point. Edit: i just looked at the printer you are using and i do reccomend upgrading to a better one, even a cheap 150 dollar printer will be leaps and bounds better than the monoprice maker. Anything will most likely do but i suggest getting a printer with things like auto bed leveling and z-offset.

Don't call it a failure if you learn something. call it feedback!

I'll the first one there when you announce a garage sale!

i recommend the prusa mini, i have it and its super reliable and i never got spaghetti but it still costs bit more

Post more failures, probably a great way to field the community for possible solutions/ideas to the problem

Monoprice Maker!!! I haven't seen one of those in yeeaaaars

You want i should have the aliens contact you to help?! 😁😝🤪🤣😱👍👍🇺🇸

A thick chunk of copper wire 8-12 awg, some math, a piece of pipe, and bingo a helical antenna.

I'd like to see capturing L band NOAAs with the HackRF, I have one but I've never been able to use it for that purpose (mostly because of my cr4ppy anntena). Or maybe some other satellites that do require the higher bandwidth that the HackRF can provide, either on another band or L band as well.

It's a shame you can't nail the 3D printing, mate. I've got the cheapest Ender 3D V3 and it doesn't miss a beat. Mind you, I have tried to print anything that is really tall and thin. I'll give it a crack and get back to you.

I'm just over in north st. paul if you ever need help with your printer. I've been through about every fix imaginable on my ender 3. I have tamed the spaghetti monster many a time.

Oh yeah. I have to put LNA in when I’m tuning the microwave that the helicopter sends out. Especially on the St. Paul antenna. A lot of interference around there lol.

In terms of filters, this might be of use; there's a site with several "recipes" for L and S band cavity filters I've been referring to lately. They're all constructed from aluminum box section, aluminum rod, and a pair of SMA connectors -measuring, drilling & tapping is about all that's required. Tuning it up using your VNA would be the only "electronics-y" bit involved. Also worth noting that these should perform just as well or better if constructed from copper, which allows for easy soldering (I'm about to try one for L band using blank copper PCB and copper tubing - I'll let you know how it works out!) RU-vid's a bit weird with URLs, so the title of the page is "Practical cavity filters for the frequency range 1GHz...4GHz" by "Matjaž Vidmar, S53MV"

3d printers have come a long way since your model. Most of the new ones are practically appliances that require minimal calibration. It would totally change your outlook on the technology.

Nice Video!

You can try to use MMDS converter for S-band recieving with spiral antenna

Im here because of the Mythbusters shirt! 😁

KITTY!!!!!

"I have not failed, I've only found 10,000 ways that do not work" - Thomas Edison. Don't be afraid to fail - that will stop you. Be afraid of stopping. When you stop - THAT is when you fail.

Try using hairspray, or glue stick on your printed.

i wonder if you you can monitor a network like this and do some sort of pattern matching/anomalie-scanning, or execute side channel timing attacks etc

i know you hate buying things but the bambu AI mini is worth the small amount it costs. takes the headaches out of printing

once you get to grips with the HackRF you will wonder how you lived without it .. Believe me! :)

Get a proper feed with the LNA on the back -check your LHCP and RHCP you might have it backwards

CATS _still_ gonna CAT...😊

Now you just have to make your HackRF mobile and get marauder on it. 😉

When was the last time you serviced your 3d printer?

For 3d print are you using supports? I think yours is a slicing issue without supports.

Get a resin printer dude, FDM is awful.. mSLA printers are truly the future. Strong, accurate, quick, reliable and easy to use.

Hmm, I wasn't impressed with the HackRF out of the box. Like yourself my first test was just "broadcast FM" and I was not impressed with the noise, the absolute first upgrade has to be the extra cans for the PCB and a metal case.

Blurring your tags is ruining all the fun....but you forgot to blur the reflection......bwahaa....bwahahahaha...bwahahahahaha.....😂😂😂 Great video as always

You need to setup your 3D printer to match their settings. Me, giving you, a print to print, is like me asking you, to give me your shoes... they might fit... but would they work? Nope. That, and you need to optimize your printer. Store bought is not good enough. You need anti-vibration, proper transmission of forces from motors to moving parts and so on and so forth. I'd suggest you get a CR-10. They're big, decently made and more importantly super easy to work on. You need vibration dampers for the Y and X axes and this comes with the fact that you need to have the belts only tightened to the point where you start to see the motors move on their dampener cradles and no more. You need a filament cleaner sponge on the filament and your filament shouldn't be left to suck up moisture. Then there's settings in the slicer and so on and so forth (these are easily found online). You need to focus on it if you want to succeed at it. I agree that many projects are cool, but if there's one thing i can critique is pond skipping. You're setting yourself up for failing. You have all the required knowledge, you're skilled, you're clearly more than capable of learning, just pick something and stick with it. 3D printing is something you can majorly employ in your projects - therefore worth the time cost to setup. Once you're setup... it's as easy as pie. I'm not joking, the last time i tickled any of the settings (mechanical or software) on my machine was in 2019. I've run in excess of 200 rolls of PLA and ABS through it, only changing nozzles and a dead fan. Don't take this as bashing (or however kids call it these days), just that it would be sad for you to give up on it. If i could get it to run, you shouldn't have any problems with it.

That shirt is fucking glorious.

bro im more like a computer dude, but i'm really sure that you will find them alien! till then i will watch and monitor you from german youtube tv

Can you try to get footage of the hurricane!

I tried Derek's feed on 3 different known good printers and all failed. I modified the feed so it has a triangular support structure in the middle and the top connecting all posts together and it printed first go. I did add supports and rafts aswelll (5 faiilures at this point, wanted to be safe).

you need more power on your side of the feed DB'S FCC be damned

Gabe, I look to you to learn new stuff about satellites, the ISS, and rail karting. Don’t sell yourself short Gabe.

Hi I rarely comment but I wanted to ask you or you ask people who will read . I would like to accomplish what you do and I wanted to know if you have resources such as certifications or books to learn how to do it

I wish you'd go back to those wireless microphones, they sound so much better than the wild sound shotgun mic on the top of your camera.

nice shirt

4:53 NOAA 20 transmits imagery on the S-Band?!

Comment Holder >>>> (ill edit something witty in here later)

That shirt looks familiar. Wasn't there a controversy around it or something?
