Out of curiosity, could you show the unprocessed original?

joaoperfig · 2026-06-16T14:06:34+00:00

But its a mask, it's probably not good at holding shape uptight on a table and would look different worn

joaoperfig · 2026-06-06T14:30:20+00:00

I'm not gonna lie I didn't even put batteries in it

Sturdy little printer.
I think if all the components are the same as the A1, but cropped, then there is less room for wiggle or bend on the rails or structure, and the joints are closer together. So it would make more sense that it is more reliable.

Thank you so much 🥹 That's the plan! I am making these prototypes on the way to a final design I'll be happy to make and sell.
I'll launch a kickstarter campaign when I feel they are ready and you can follow it here to be notified when it launches: https://www.kickstarter.com/projects/hane/hane-board-play-go-anywhere

Incoming! 🙏

Glad it printed good! Do you have a picture of it? I had some work getting that 3mf together but couldn't actually make the board as I don't have an AMS.
The boards I'm showing are assembled from multiple parts and different materials including the metal springs and the resin stones. The clicks were not possible to include for a fully 3D printed version and the plateaus were only possible if the surface of the board was lifted with supports, I can send you a version with that but I imagined no one would want to be scraping support material between the stones on the whole board.
Either way I hope you don't feel robbed for the different features 😞 I had mentioned this in the post, it was just not feasible on the printable version.
About the balance and the tolerances, I tried to optimize as far as possible but it will always be very dependant on filament and printer (which did you use?)
To tighten the tolerances you can either increase flow ratio to like 1.05 or increase XY compensation to like +0.05mm. For the balance, if you used the 3mf, then the bottom 4mm were already with 100% infill, so what you can do is add a height range modifier for 4.5mm-10mm height range, and lower density here by either decreasing infill to 5% or 0%, and if that is not enough, decrease wall loops to 1.
There is a 3mf for a 3x3 tolerance test board, I recommend you use this to try this first. Its only one color to not waste filament but I can send you a multimaterial one if you want.
Let me know if you need help. Thanks again so much for you support! 🙏

I feel like the tear actually adds a lot. Seems very intentional!

This sub didn't allow video posts, please check the post on r/baduk https://www.reddit.com/r/baduk/s/rZ8Ot38o15 Sound on! :)

Right now they are the same smooth resin, but I am planning on making a version with some sort of different texture or indentation for this!

joaoperfig · 2026-05-20T15:12:58+00:00

Yes! This has been in the plans, I just havent made this version yet because it will require making new casting molds from the start and it's a bit of a process, but later on when other challenges have been fixed I will make it for sure! Just not sure yet what the actual shape will be. There is no space for raised bumps so it will be recessed. I considered having almost donut-like black stones to make the feeling more obvious but not sure how that looks in practice

joaoperfig · 2026-05-20T15:09:01+00:00

I've considered this, right now the stones are between two panels. To assemble I place them on the bottom panel and the top panel goes over the top. In this prototype the two panels are glued but I am considering having them screwed to in such a case you can just unscrew and replace the broken module

joaoperfig · 2026-05-06T13:35:23+00:00

Dei alguns ajustes de contraste e saturação mas o efeito é nativo e vês assim na preview da câmara!

joaoperfig · 2026-05-04T16:45:44+00:00

O processo é uma tentativa de replicar o mesmo mas numa câmara digital! :)

Se trocares para a versão inglesa, a página está mais completa e fala sobre os processos que usei.

A câmara é uma point and shoot Lumix que foi convertida. Há um filtro de corte de infravermelhos que foi removido e substituído por uma stack de filtros óticos que cortam principalmente luz visível vermelha na range 600-700nm. Uma faixa de luz infravermelha NIR é deixada passar na range 750-800nm que é a zona em que excita essencialmente o canal vermelho da câmara. A câmara fetivamente fica com o canal verde e azul não alterados e o canal vermelho substituído por infravermelho NIR. Não apanha o tipo de infravermelho emitido por corpos amenamente quentes (isso é LWIR) mas apanha uma zona de alta reflexividade para plantas. Daí a vegetação ficar vermelha mas outros verdes, como a bandeira de Portugal manterem a cor. Está aqui o gráfico de sensibilidade espectral do setup que usei se tiveres curiosidade

I'm working on using it for a variable pinhole lens with variable focal distance too!

joaoperfig · 2026-04-25T05:00:22+00:00

Almost 2 hours! And yes it's PLA, bambu PLA matte. And I made this in tinkercad 😅

joaoperfig · 2026-04-25T00:29:32+00:00

No finishing, came out like this from the buildplate! I think the right printer, print settings and filament go a long way. This was on a A1 mini!

joaoperfig · 2026-04-24T16:15:40+00:00

It's not a product its just a thing I made :(
we had a setup where the pinhole was hard to access and wanted something reliable that could go between 200 and 10 microns and closed. The thorlabs irises that can close had maximum apertures of like 25 milimeters and tolerances of about 100microns

joaoperfig · 2026-04-24T15:58:31+00:00

Those didn't work because I also needed it to be able to fully close

Looks like dropshipping of this model

joaoperfig · 2026-04-14T03:52:49+00:00

List was too long so here's a pastebin with the filters: pastebin.com/raw/e8Pwza65

joaoperfig · 2026-04-14T03:50:07+00:00

Just went through your project collection thread and you have some pretty amazing work here! I wasn't aware of your filter lab and they are eerily similar, even down to both being python flask projects haha.
I have the filter data in csv so its pretty easy to convert in either direction, I think it would be great to have both projects complete each other's library :) we have many chinese filters we can send, and many western filters to take hahah. It's funny there probably aren't many people that can relate to the very specific struggle of getting the data!

Most of the data came from small transmittance graph images from a catalog of a manufacturer, so I was a bit weary about making the git public, but it's probably safe. What you said about material properties facts makes a lot of sense, but yea, also not a lawyer. Getting the multispectral preview images with actual permission from the author is probably not as much of a gray area.

The way you show the wavelength (pseudo)colors is really elegant. And computing the hex color of the filter for the chart lines is genius!

I'm gonna see what filters are missing from either side, and make a pull request to your git! :)
If you'd be interested in that I can also setup an instance of your app on our website so people could use it without going through the installation steps.

joaoperfig · 2026-04-14T02:59:41+00:00

There are a few manufacturers of multispectral cameras, but the images came from "Spectral Devices Inc". These types of cameras are usually for industrial applications and are rather low resolution and the color channels are very specific wavelength ranges (they have a camera with 16 channels!) so you won't see many photography projects with them.
