Quick tip you should never try to fight convection when air cooling electronics. The air in your box will tend to stratify cool on bottom hot on top. Also forced air cooling work well BUT it degrades over time due to dirt and junk in the air. In your application moisture could WILL become a problem. Pulling out side air into a box that has set in the cold over night can cause condensation. I worked in the thermal management part of the electronics industry for abt 5 years.
A few years ago I built a QFH antenna out of pvc water pipe and computer network coax. I connected it to my dedicated APT receiver which works in the 137 -138MHz range and ran the output via a PC soundcard into WXTOIMG software, I got some really impressive results. But after a year or so we had a bad storm which obliterated the antenna (I mean totally mangled it) and I need to get it all back up and running again. Cool video.
Impressive build my friend, i did something similar years ago with a wee yagi beam and got great images too but occasionally I would get a lot of distortion to the images on some passes which made me realise that this can be caused by a few things mostly for me seemed to be heavy cloud cover.
The more I learn from your videos, the more I read books which go into the why's and how's of the terms you use. As I said, I know next to nothing about electronics/computer/radio, so I keep on with my reading and continue to watch and learn from your uploads. Thanks for your work in getting this out. Best wishes from the hills of Virginia! Cork
hi, Canadian living in Brasil here, i also run qfh antenna, on a pi4 with the nesdr smart, but ive had to remove my nooelec noaa filter for better meteor signal for a reason it was not working well maybe it kinda center the frequency to much, everything at gain 38.6 for me, it run like champ. good video keep it up!
For all my remote radio systems with the rpi, I use power over ethernet (POE). There is an adapter that can both put POE onto the cat 5 and take it off at 5v. I use a POE enabled switch, so I only need the POE adapter at the rpi, it powers the pi, and the rsp. I then use WinSCP to move the images from the pi to my main computer. I copy the GOES birds this way.. Great video, especially the antenna, I will have to try that.... Thanks de wb7ond
A very beautiful helical antenna, I haven't watched all the videos on the topic yet, but the helical antenna has a directional characteristic, and in your arrangement, the signal maximum would be when the satellite is directly above the antenna. That would be a good antenna for automatic tracking. I wish I had such a cool neighbor like you. 👍
Watching this video again after finally getting around to getting the ball rolling on my own Raspberry Pi weather station that I have been planning forever. I'm starting the other direction though since I'm starting with environmental systems first, and I think I'm going to probably go with GOES data when I get around to adding a satellite receiver to it. I would like to play around with using a small antenna to detect lightning first though.
I want to redo this, it's been on the list forever and I've been trying to find time this spring. I still have a box of weather instruments (and I think I have a lightning sensor module!).
Great projects enjoy watching. Keep up the interesting projects. Weather satellite project is part of my interest and ham radio. Need more info on weather satellites. TNX Rich
My weather system cost me $0 and very easy to install ! Get 1 18” willow branch , mount it on a board and if the stick is wet it’s raining if the stick has a shadow it’s sunny and if it’s white it’s snowing and if the stick points up it humid and if it points down it’s dry ! Lol
5:55 Using Ethernet in my Orange Pi, I noticed a lot of noise on the receiver. I had to connect to the network via Wi-Fi, as interference clogged the signal and degraded the quality of the received signal. the interference on the receiver's waterfall looked like a picket fence made of sticks
Meteor 2 is down on LRPT. Suspected micrometeor damaging power/battery systems. Analog 137mhz cannot (won't) operate on alternate power mode (solar panels only).
It does corrode over time, but it doesn't seem to affect the performance so far. I think the main benefit of copper is it's easy to shape and work with.
6:13 i wanna ask something. I never did any hardware-y project in my life but hot air rises up so shouldn’t the fan be placed above actually? Or does it have any effect anyway because what processing does the rpi even do that would be considered heavy/heating for it?
@@saveitforparts yeah that makes sense, my bad! I really like this project and wanna do it as well even, except that SDR dongle is actually pretty expensive, and from all the other stuff you used (filterers or what was it, gain boosters?) it seems like I should be careful what I am stepping into. Keep it up, I really enjoy your satellite videos a lot. The amount of trial-error you go through makes it worthy.
i don`t think it`s possible anymore. I tried the alternative link to collect data from there for the satelite passes and kepler updates ,but doesnt work. Replacing the weather.txt file with up to date data also did not do anything. When i try to update the GUI it stucks on 2 % and that`s it. If there is command line workaround let us know. Or u want to just upgrade to the Pro version ? In that cases - there are keys online ...
Not bad, and the pictures looks wicked..dont worry about it 10:24 the "ekh" is more less silent.. so pronounce like a (horse)jockey.. You dont have a HackRF.?
Right? The good old days! People keep asking why my recent projects are made from 90s junk instead of Raspberry Pi, it's because I can't afford to get another one!
Curious how you make money? Cause i don't work right now and need to start getting enough to pay bills i have lots of stuff i could sell but its a headache on Facebook marketplace
I have a regular job, TH-cam doesn't make enough to live on! Sometimes I've sold dumpster-dived stuff on eBay, but they changed the shipping recently to make it harder on small sellers. I've occasionally also sold larger stuff on Craigslist or Facebook, but yeah that can be a pain.
As a pilot, and complete weather geek, this is the most incredible thing I've ever seen.
I came for the Potato Howitzer, but this channel looks really interesting, So I think Ill hang around for a while.

you should add heat sink on the RPi 4 , that may help with heat problems also it will stop the thermal throttling
I was gonna suggest similar, or at least another fan mounted sideways next to the Pi to blow air across it.

I remember hand coding "wefax" for the Tandy CoCo2 back in 1985 to get a "fax" over short wave radio.
I rarely have much idea what he's talking about, but it's still so cool!

I think you're my new favorite channel, "save it for parts" have always been words to live by for me

9:52 the spacing and drift of the banding reminds me of the feed from the starlink satellites on the waterfall display of SDR++

@@saveitforparts I will keep an eye out for the video!
That antenna is a work of art. Great video, thank you!
The wavy lines are the sat signal being stamped on usually by a Meteor sat
Truly you are an amazing guy!
Awesome build
Killer setup! Maybe enough room for a solar system 😊

There's a lot of great info here: usradioguy.com/ , I've used a lot of his how-to guides and antenna suggestions.
Very cool, I always learn something or at least I enjoy the heck out of what you are doing.
gotta love being surrounded by hills...
love your shirt man!
Potato howitzer to satellite images?
Mom i found the best Channel
Wow that's lots of fun

Consider installing some chokes on your USB and power wires.
I don't think plugging the sdr directly in will effect the signal much. Usb is a digital signal unlike the antenna and coax which is analog
love it.
Sei intelligente , bravo! Good one! Greetings from Italy , love that project!
"This is a really dumb idea, and probably won't end well" as I run off to dig through my Junk Box for parts...
DAM BRO your one smart cookie !!!!
Outside box try not to run wires on top, if back or sides it run off on top it going to pool before it runs off....
I like how everything always sounds normal to me until he says "ruff" xd
should make a shroud or pipe from fan to just below top of box, even just the length of a pringles can will improve thermals. you have room
Nice build! You got yourself a new sub. +1
wish the RP 4 was still that price :/
Hi from England,I love seeing you on the rails and was wondering if one day in the future you could borrow a speeder rail car .🚂🚂🚂🚂🌠
Love it.👍 thanks
Not sure what landsat uses, but they have scan line issues that are resolved in post processing.
I told every one I could about the
potato gun toe behind , 👍
Great channel dude ,!ov-iT ✌️☘️✌️
You don't think there's a little power bleed causing you the issues with the interference
Could be, things improved when I cranked the gain all the way up, but I'm sure I could still tweak it more.
So you come up with a part 2 of this video??
It's on my to-do list! I just haven't gotten around to putting more weather instruments up there.
1st...Like your shirt, " THE GOONIES " ( Hey you guys ) great movie..
Do you think you can build a time machine to go back in time, if so, I'm In....
Oddly enough, you can buy a new Delorean "from parts," so you could build a time machine and still be in the spirit of the channel.
what's stopping the spiral antenna from building up zinc? do you have to occasionally bust rust?
It does corrode over time, but it doesn't seem to affect the performance so far. I think the main benefit of copper is it's easy to shape and work with.
a little late but i have that exact goonies shirt lol

I'm just using the fan to circulate some air, I wanted it in the bottom to help keep water out.

You can your an old or new ammo can
Is it normal for a 15 y/o to want to build one?
Probably! I built all kinds of weird stuff when I was 15. Most of it didn't work, but nowadays at least 50% of my inventions work :-D

A raspberry Pi 4 for $35... wow.......

So are we gonna be able to pick up the "alien" transmissions or wut! 👀👍
