Images From Space: Receiving Weather Images Directly from NOAA Weather Satellites
In this video I am showing how to receive weather images directly from NOAA weather satellites in space. A simple V-dipole, a RTL-SDR V4 software-defined receiver (SDR) and some free software is all that is needed to receive the satellite based APT (Automated Picture Transmission) signals at home. SDRSharp is used to FM demodulate the received signal, WXtoImg decodes the demodulated audio and creates weather images from the received data. At the time of this video, there are 3 NOAA weather sattelites (NOAA 15, 18 and 19) that transmit weather images through the APT service in the frequency range of 137 - 138 MHz. Due to the relatively low frequency, a correction for the doppler shift can be neglected by chosing an appropriately high demodulation bandwidth.

Hello what is the model of the power supply? I didnt know laser power supplies could vary the voltage....i thought only current. Interestinf
It's a VEVOR 50W CO2 power supply
Please brother, we need mathematical operations.
Does the radiacode 103 detect alpha, beta, and gamma, or only gamma?
The Radiacode detects Beta and Gamma. Alpha traces are optained through secondary x-ray emissions or Bremsstrahlung
Most of the time, I can't replicate the results I see on CZcams, but since I have all the components, I'll give it a try. Anyway, great video. Thank you very much!
Exactly that was my intent, easy replication without highly specialized equipment. Let me know how it goes!
You know any sellers that sell gunn diodes in the Thz range, or as close as possible?
@@ralfschooneveld3186 Unfortunately, no. I think you'd have to go through some multiplication stages to go up that high.
@@BalticLab Ive got a paper where thery went up to 0.1Thz and 0.48Thz, but no details. ''Frequency multiplier units based on SBDs, impact ionization avalanche transit-time devices (IMPATTs), tunneling transit time diodes (TUNNETT), and resonant tunneling diodes (RTDs).
@@ralfschooneveld3186 That would be 100 GHz to 480 GHz, no need to express that in THz. Though many research papers want to push THz, so they use stuff like "near THz" to push keywords.
Pair of tweezers . Grab resistor . Bend left then right and comes off every time. No heat needed.

how about a project that is unique, instead of something dozens have already done, and the information is available for free on NOAAs website? or is this some kind of product marketing type video?
Thanks for your comment. Especially for DIY, electronics (and other science related) topics, it'd be hard for creators to post highly original content that hasn't appeared anywhere else in some shape or form. And I think it's perfectly fine to post ones own version as every creator has a different take on things, a different presentation style and focuses on different aspects. Also, topics such as this are easily researchable if the person is aware of what to look for. Many people do not know that they can receive weather satellite images themselves. So of course this is interesting for people who never stumbled across this before. That others have done something similar, or highly adjacent, is something I frequently mention in my videos because - unlike other creators - I actively encourage viewers to look around other channels. People like different presentation styles and formats. So if someone finds a different creator after watching this video, who better matches their prefered style, I am happy for them. From my research I am the only one showing a very simple V-dipole directly into a RTL-SDR on a Windows PC. So while the topic isn't new, this is a differen take on things.
Eagerly anticipating your video.
Too many ops within the sphere 😂
👍
Newbie question: why the output has just one terminal? Where are the positive/negative that I should connect to a jack, for ex. Thank you!
The output is the desired signal, the counter-pin, or reference pin, is ground.
Would this be the same for the FT8900R
I honestly don't know but some viewers indicated that its the same for tue 8900
Great video. I'm interested in replicating your power supply for use in an electrospinning device that requires between 10 - 30 kV. However, most commercial power supplies (such as the SKE EF020) limit current to around < 1 mA. Is it possible to reduce the current in your design whilst maintaining high voltage?
You can limit the current to 1 mA by adding a current limiting resistor in series. Just make sure its appropriately rated for the voltage and the dissipated power.
@@BalticLab Okay I'll give it a go! Thanks for the reply!
The gmc 300 geiger counter measures wrong with usvh, its only cpm that works accurately
Unfortunately, that is true. I now have a Radiacode 103 and the differences are quite significant: czcams.com/users/shortsAVM8EzvVCiI
We don't want anything American, but thanks anyways
@@robert48719 Basically 😅
Perfect: Keeps your food warm for the next 30,000 years.

I am a student studying flicker noise, is the y-factor method valid for measuring flicker noise?
Hi! That's probably not a good method for measuring flicker noise as thermal noise us the reference, yet all test equipment will bring it's own flicker noise issues with it.
If you have a FLIR camera, you can try to see the beam itself. Perhaps some smoke is needed too.
Is this under black light or is this emitting light with hydrogen peroxide?? So pretty! I mixed rhodamine b and fleuroscine with rubbing alcohol but never hydrogen peroxide..
It's an aqueous solution with NaOH and hydrogen peroxide. Basically the standard luminol recipe except with multiple, unstirred fluorescent dyes at once.
@@BalticLab can you write a concentrations of the solutions, please? I'm looking for a colorful experiments for kids and I will be very grateful if you send an experiment setup
👍
I wish to see an updated version, please do it!
You are an amazing teacher
Thank you. Glad you liked it!
@@BalticLabloved it. Can you a video of adc and i2s too? Thanks
I'll put it on a list. My top priority item right now is to redo this video a bit more modern.
@@BalticLab that’ll be great. Appreciate the efforts
I need this!!!!! There is a tutorial????
Here's the code: baltic-lab.com/2023/08/tremolo-dsp-effect-for-arduino/
I guess this is a receiver How about a transmitter ?
I already showed a Ku band transmitter (czcams.com/video/jWDu2BkVWnw/video.htmlsi=5riGTQkg_tibKkyl) but a teardown of the BUC would indeed be a great idea!
Those bubbles slow down the etching a lot. If an aquarium air pump is added to mix the etchant the process takes minutes. I've built a flat tank from acrylic for this purpose, it reduces the amount of liquid needed and placed the outlet of the air compressor at the bottom. The liquid gets stirred extremely well.
Nice setup, these Chinese laser tubes are cheap but dangerous due to their highvoltage wiring and safetyless HV power supply. 30kV with no proper HV shielded cable and a return path to the power supply housing is a deadly combination. Water ports are fragile. Life time is abit over 1 year then to the trash. Beam has usually side lobes and not pure gaussian, so this thing good for average quality production in job shops.
An RF supplied CO2 laser is much safer and compact and servicible but more pricey.
Btw I still remember your Wilkinson combiner tutorial about 7 years ago. I still rely on that knowledge for my RF designs ;)
Good to know. That Wilkinson video apparently has quite some popularity I was invited to give a lecture on Wilkinson design at a local university recently after many students referenced my videos in their lab reports. 😄
Yes, because delivering Information clear enough to understand is highly appreciated.
Very interesting video! Not sure if this would be something you are interested in or have the time for but I would really appreciate much simpler and in detail versions of these videos. An "explain me like I'm five" version so to speak. Questions to answer could be: What actually is a LNB? What does it do? How does a horn antenna/waveguide work? How does the amplification work? And how does the signal look like that is being amplified? What does K-Band mean? There are a lot of channels explaining the basics of electronics but I think application-oriented explanations would make these theoretical lessons much more interesting. I know your channel is probably for viewers with more knowledge about electronics. So it's just a suggestion :)
Actually a great idea. With the depth and complexity of RF I will have to think about how to best do that, whether it's gonna be a 1 hour video or 10 segmented videos. Maybe a combination, a teardown vid followed by derrivatives of interesting features in the design.
🛰📡
Are the 38khz sidebands AM modulated? (prior to FM modulation of the whole signal for transmission) If so, that's kind of funny that FM stereo contains an AM component.
It's double sideband modulation for the 38 kHz subcarrier. This modulation type stacking actually happens a lot. FM subcarrier modulated onto an AM signal is used in aviation VOR stations for instance.
Interesting IC. It replaces the dielectric oscillator, mixer, amplifier, voltage comparator and 22kHz detector. 20 years ago this would all be discrete components.
Yes indeed. Actually, one of my very first videos was an old C-band LNB teardown video, huge difference: czcams.com/video/DkURL4mETT4/video.html
My good sir, 2024 remake with a side of schematic please
Duly noted!
"2024 Remake" please ;-) Am I the only one ? And of course "Schematic". is always handy ! Thanks !
Can anyone please tell me which resistor can change the gain or the output level of the pre-amp?

I remember having a drawing of how to use a spark plug on a marine motor to make an emergency radio signal......kept the small drawing in my billfold during my boating years but lost it. would like any info on making an emergeny xmitter using an outboard or inboard marine engine
That's a very interesting idea.. Since I have an outboard engine on my sailing yacht, I'll put that on my to do list for interesting ideas.
Thank you for the kind words! Good luck with all your future projects!
No Problem, I have absolutely no problem directing viewers to other channels if they make great videos and you sure do! Thanks so much.
I grab you 😆
fyi, a CO2 laser is around 10 micron (mid-ir) wavelength and cannot be frequency-doubled to produce green light. to achieve this effect, your source laser must be around 1 micron in wavelength.
Correct. I know that now but I don't censor my mistakes afterwards, it's part of the journey. :)
Arduino giga is still to expensive , with that price we can can get direct multi effect guitar
Agreed. I was hopeful that the price will drop after the Giga is more estabished but so far it's quite pricey. The Arduino Uno R3 might be a new, inexpensive but powerful alternative. I have one here and will check into it.
Thats helpful, thanks!
Glad you found the video helpful! P.S. Been subscribed to you since whenever I discovered your channel.
@@BalticLab Haha, tnx!
