But would it be possible to add an RSS feed to your blog please? (https://rootkid.me/works) That way I won't miss any of your future posts.
And I used pcbway for the sheet metal fabrication
Honestly they are both great and similarly priced
Where did you learn all the PCB design stuff to make your circuit boards that controlled the filaments?
You could probably do it with a cheaper SDR, but it would be slower
Total budget for this is around $1k
When I was doing wireless stuff we'd show customers the output of RF analysers to show that even with their wifi turned off their spectrum was packed full of noise.
Having a large viceral display of this would quickly enlighten them.

I think one fun application would be a light which represents your wi-fi strength around the house. Obviously in a smaller apartment that's really not a problem, but in larger houses it would be fun to see.
Another application would be to find hidden RF sources / leaks. I have a home recording studio, and for the life I could not find some RF source that kept adding noise / interference. I could roughly detect the frequency of the noise, but not its origin. I guess if I had a couple of RF sensors I could try to triangulate my way to it.
But tuning in to the specific wifi channel you router use you could even use this piece as a signal strenght plotter!
Seems like it wouldn't be hard to filter this for something like the 2.4 or 5GHz range then put a different color filament at the demarcation point for each of the channels.
I watched TONs of youtube videos growing up and I guess I took inspiration from what I liked in each: fast pace, always shows what you are talking about on screen (no talking head), include tiny projects in the main one, explain the science, use an intro to captivate and an outro to nail the point, use music to drive rythme
I film and record audio with just my phone
Another question that I hope is not disrespectful: does PCBWay and JLCPCB pay for brand placement during the video or was it just a tribute from your side?
Just don’t tell anybody you’re a copy-cat.
I was just thinking about this the other day, and wondering about directionality...
For example, if you had a camera facing a space, and the receiving antenna was within that space... and you were able to (somehow?) from the antennas perspective, see the "direction" the frequency was coming from..
And then map the different specific frequencies within the desired bandwidth to colors... and of course intensity map like you have in the slit device..
And then "look through the camera"... you would see a live three dimensional overlay of all signals within range (colored!) "interacting" with the antenna... but kind of more the "looking through the camera" sort of view, like you could "see" how those waves were interacting..
And then wouldn't it be interesting to put a tin-foil hat to one side of the attennas.. and see how the waves change in real time... etc.!!!
(I guess it takes three antennas, to triangulate the field? Maybe all three can still be mounted on a single device in close proximity?)
You can kind of do that quite easily at low frequencies, by measuring the phase of signals coming in from a pair of aerials. If you put two aerials a quarter of a wavelength apart and switch between them very quickly at audio rate, then you'll get a tone when there's a difference in phase. If there's no tone the two signals are exactly in phase - the two aerials are exactly the same distance from the transmitter.
If you look on some police cars you'll see a group of four aerials about 15cm apart stuck to the roof which used to be used for "Lojack" style trackers.
There are a whole bunch of circuit diagrams floating around for doing this kind of thing, with the simplest being Ye Olde 555 timer and a couple of PIN diodes!
And every time I see something like this I like to remind to myself and imagine what spherical grid of Starlink satellites linked by laser is really capable of instead of mere internet as it is advertised.
What would really finish it for me, though, is if, when the button is released, the device shows a website, with URL visible, with a photo of the criminal, with added facial recognition and lookup of social media to find their identity.
What fun!
I'm precisely asking for speculation on what this data could be, which is the goal of the artist as stated in his video
Respect to the artist, I know I couldn’t do it.
With this said, if they are not content creators, you'll never know about them. That's not any different than the past were art was typically only known to those with in viewing range of said art.
We're bathed in EMF. It's what light is, but aside from that we use electricity so much now, we're in a sea of radiation in other frequencies too.
(and they cost like 5ct each)
Depsite visiting Hackernews multiple times a day, I am not a tech person. Seeing people creating such thing in a way I can undestand (which is maybe...10-15 % of the posts here ?) is so refreshing !
The editing is sharp, the setup looks so cool and the channel !
Thank you for making this !
I guess it's a good commentary on how tech people value other peoples work.
