What would it be like if our eyes could see more colors? We may never be able to answer that, but we can build devices that can do the work for us. Over the last three weeks we've been building a DIY radio telescope tuned to 2.44 Ghz which is right in the middle of the wifi band. With it we hoped to take a picture of a building and see all the wifi routers inside it. This is the third part of the series and I'm pleased to announce the project was a complete success! If you haven't seen the first and second videos, I'd highly recommend watching those first.

This week we mapped the inside of the hackerspace (Foulab) I've been working in and then stepped up to taking an image of the whole building. Not only were we able to see our router, we could see at least half a dozen others, and even one across a courtyard at least 100m away.
The images were very large since they were full 360 degree panoramas, so too get a better view of them head over to my facebook page at the following link to see them at full size!
Image 1 Inside the building: bit.ly/2LXmA92
Image 2 Full building: bit.ly/2JZMvfI
Want to try and build one of these yourself? Here's a link to all the code needed to run a robot like this and turn all the captured data into an image: github.com/FOULAB/Project-COG...

@@LightCodeGaming We use to use a setup like RFID for finding radio transmitters, an antenna and receiver is a tuned circuit with a standing wave ratio, it will echo back some power when you apply a signal to them.

@scurvofpcp 5 лет назад

@@LightCodeGaming They can be found in some prisons and such, these devices are prone to false positives though, and it is a PITA to keep them up to date with the latest tech. One major foil to these types of systems is that high freq singles respond poorly to things such as concrete and metal, metals can both reflect and absorb at that freq range and concrete tends to absorb as well, so it would be a very limited use device for such a thing. Personally if I had to invest the coin for something for use in that, I would lean to an active RF Detector, yes I know there are edge cases where the phone may be powered off but still functional, but it is far more practical to detect a transmitting device then to hope for a lucky echo, that an a safety concern is that anytime you have a building collapse there is going to be many unknowns and it is plausible that an RF transmitter can cause other metals to spark, all it takes is a bit of coiled conductor with some oxidation that just happens to be making partial contact with a grounding surface.

I get home and this video pops up in my recommended videos. Amazing 😂

@psilobom 6 месяцев назад

@@vzgsxr If you saw in the Electromagnetic spectrum only, all you would see is likely a black and white gradient between high and low signal sources, because the electromagnetic spectrum does not reflect or interact with solid matter like the visible spectrum does. You would not be able to see anything physical, and would be blind to most perils around you. It's likely life could have developed with a way to detect this signal, but unlikely, because it would be relatively useless as a way of navigating the world around you... unless you wanted to find Wifi routers?

@seraphina985 5 лет назад

Geosynchronous can also include elliptical orbits with a period of exactly 1 day also which results in a position oscillation in the East-West rather than North-South direction of an inclined circular orbit. Of course there are synchronous orbits that are both inclined and elliptical also which cause the satellite to move in an Analemma in the sky. Of course there are plenty of other orbits that are at least semi-synchronous and repeat at intervals too commonly used for activities like Earth observation when higher resolution is required.

@fiveoneecho 5 лет назад

How to check if someone's broke by judging their wifi strength

@Aniisananime 4 года назад

I think to do that you can- Step 1. First check the strength of the signal when your average number of devices are on. Step 2. Add one more device and now check the strength of the signal. Subtract the value from the average load. Step 3. Now if you scan a drop in signal strength by the value you noted in step 2 or more than that, and the drop is originating from an unknown source then you can determine there is a break-in and from the magnitude of drop you can calculate the average number of unwanted device being used.

I suggest to rewrite the program - run the averaging during reposition - you will save the postprocessing time.

@sorin.n 6 лет назад

My idea exactly! (I scanned the comments first to see if it wasn't someone else calling it before.) In 250ms I believe you can do more than averaging it. You can also compute the final image pixel by pixel. Also, why is so much data? How was it stored? As text? (also @The Thought Emporium)

@sorin.n 6 лет назад

I understand that for the prototyping part data is important. Especially when you are not sure what to expect. I was implying that once you know that averaging it is the way to go, you might do it on the fly. Very cool project btw!

Gigabytes of data is just insane. Back of the envolpe calculation: At 3:03 you can see that the image resolution is 80 by 270, thats 21600 samples each sample is a float, thats 4 bytes, or 8 bytes if you are using double precision (which I think python does). That means the robot should sample about ~168 KB of data. HOW DID YOU INCREASE THIS BY A FACTOR OF ABOUT A TEN THOUSAND?????????? The second time, it took 4 hours, with 4 measurements per second (at best) that gives 57600 samples. Did you include a Harry Potter book in each of your pixels? 44 gigabytes is ridiculous. (Edit: with each pixel 4 MB and 44GB of data, one would actually get around 11000 samples) What is in those files that they take up 4 MB of space? Nice project though.

During development it's more important to collect as much raw data as you can get, disk space usage and processing time for analyzing the data isn't much of an issue: If you have bugs in your processing code (like the wrong averaging mentioned in the vid) you could just rerun the analysis. If you throw away raw data and just keep the (possibly flawed) results, you need to redo the whole scanning....

@AlexDlugosch 5 лет назад

I disagree about collecting as much raw data as you can get during dev. You need to choose sample rates wisely, because rather then helping development, if you have so much data that processing takes minutes or hours per pass, you could be wasting time. If it takes you a couple of passes to work out a bug or find a way to make better sense of data, having the right sample rate could make all the difference in a days work.

A hand-held wi-fi mapper would be quite a commercial success in music shops. Thousands of musicians use wireless links, mostly at 2.4 g.

Having been interested in communication's from an early age, I came up with the thought that if someone developed a machine capable of actually seeing R.F., that we very likely wouldn't be able to see our hand in front of our faces, due to how many signal's there are coming from Radio, Television, Cell Tower's etc. ! I ventured too that if nothing else, someone using such a device, would perhaps assign a color for the various radio frequencies ! Looks like these guys are getting closer to that end ! It would be very exciting to be able to visualize a radio signal, as it leaves an antenna, and instead of relying on metered measurements to try and understand the antenna pattern and gain direction, we at last could see them ! Perhaps some day ? 🤔.....📡 ???

I Love this keep it up i would love to be able to make a biger and better radio telescope and show the scouts i have a rtl and a satellite dish that i manually move. I show the the moons and stripes of Jupiter and let them completely take control of al my scopes and was showing them my rtlsdr

@brandonb3279 3 года назад

Wow that's so cool! I'd bet that the groundskeepers at the Greenbank telescope radio silence zone would love something like that (if they don't already have one)!

@TheSocketshock 3 года назад

would love to see more of this!

@HennerZeller 6 лет назад

Do you have the raw data somewhere of the indoors measurement ? I am curious and would like to play with visualizations.

@HennerZeller 6 лет назад

Cool, I cobbled something together on my hzeller/cogsworth-viz github. From what I understand, each file represents a pixel with a bunch of measurements stored as IEEE floats. Memory mapping the files makes it pretty fast to process (takes only a few seconds if the harddisk is fast).

@10p6 5 лет назад

This is an awesome :-) Your data collection file sizes are way to big though (should be Megabytes instead of Gigabytes.) It is also possible to do a high resolution sensor that would collect a full image in real time, and at variable frequencies, including numerous wavelengths of light.
