Creator here, thanks for posting. And feel free to ask me anything!

I love your works, what kind of background do you have?

CS background, but I've always been a "bricoleur" on the side

I actually got your video recommended by Youtube earlier today! Glad my YT algorithm is on point.

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.

How much did that sheet metal frame cost you from PCBWay? Thanks for sharing.

Around $200 delivered to france

Do you have a list you would be willing to share of trusted manufacturers & suppliers that you reference for different products or materials?

I used JLCPCB for the pcb cause they integrate well with the pcb design software i use (kicad or easypcb)

And I used pcbway for the sheet metal fabrication

Honestly they are both great and similarly priced

At least in the last video it seems like he used both PCBWay and JLCPCB for manufacturing

Yep! The choice of JLCPCB after having used PCBWay is what inspired the question.

Very cool project. Thank you for sharing. It's rare where something so technical can have such an artistic manifestation. Well done.

Awesome project & video, thanks for making it

Where did you learn all the PCB design stuff to make your circuit boards that controlled the filaments?

amazing project ! well done ! inspiring to see it this morning the youtube algo recommended it for me. I was thinking what would be a budget way of creating this ? maybe a $20 SDR instead of the hack rf , seems to be a waste of the hack rf to use it as a lamp :)) I think the way you did must have cost you over $1k. Thanks for the inspiration !

Hackrf is defo overkill for this. I got it cause my initial plan was to cover the whole spectrum

You could probably do it with a cheaper SDR, but it would be slower

Total budget for this is around $1k

IIRC, a regular SDR dongle will not be able to process the full bandwidth of GHZ range.

I do think most people implementing something like this, especially in the exact way this one was implemented would really just be interested in the Wi-Fi ranges.

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.

The $5 nrf52840 should be sufficient, it can scan 114 channels (from 2400-2514 MHz) several times per second, measuring the approximate RSSI.

You could not use that as an SDR to make a waterfall which is required in this case

You do not need a full SDR to make a waterfall. The nrf52840 can function as a coarse spectrum analyzer, because it lets you tune to any frequency within its range, and then measure the approximate received signal strength over a period of time[0]. I have tested this myself, and it works pretty well. The only downside compared to an SDR is that it can only listen to one frequency at a time, so it will sometimes miss short signals.

I know it can switch frequencies, but I predict it wouldn’t make a very pleasing visualization if the updates are slow, but maybe you are right it would look fine for this implementation which is already far off from a waterfall

HackRF isn't a good SDR by any metric except for the date it came out.

What would a better alternative be?

Love your channel! Do you have any plans to eventually open source your projects? (Both in terms of hardware and software)

To be honest, all of the hardware and software is really poorly documented. But I guess i coudl still publish it as is

Yes, would be still great! I'm sure a lot of people would have fun playing around with it even without the documentation

I'm personally especially interested in 'Latent Reflection'. I've tried to make something similar never got to a point where I was happy with the output the AI model gave me.

Lots of tuning to get the model to not immediatly spiral into nonsense. But small models are getting better by the minute, maybe i'll revisit it with a better model and share all the code

That'd be really appreciated. For me it just kept repeating the same phrase or just started reflecting on the prompt itself for a sentence or two after which it started spouting random nonsense like a pasta recipe.

You’re very good, I’m jealous of your work

Nice art and a good way of story telling. Thanks for your work!
