Its official. The Pixel Pump 2 is coming 🔥
Will do a proper introduction video soon but here's a few interesting specs 🧵
(It's a tool for PCB hand assembly)

I swear I had my units in meters before sending it to the fab.

ゴミか？ 切粉か？ ん⁉ 部品なの⁉

@entropyconquers @FatalHydra Dang. Everyone (me included) was hoping for some Remotion magic or so that we can easily reproduce 🥲😂
Wild times..

I made a React Native Drag and Drop library that finally works! [v2.0 release]
10 months ago v1 became the top post of the month on r/reactnative. Since then: hundreds of stars, tons of community feedback, and all of it shaped this release.
Demos below (1/5)

I feel like there is a bubble about to pop.

Tried it out. So the product scans stuff, then it shows Reddit tells me people post about my company, surfaces competitors I already knew about ages ago, wraps it in a dashboard, and wants me to scream “OMG we saved $60k. At this point I’m convinced half of startup hype is just polished demos. How’s this the “ultimate CMO” for me
English
@JamesMcPherson Awesome! First thing I’ll check on Monday. Thanks!
English
@robin7331 I just did a test engraving on PCB. I used 40kHz , 100mm/sec, 80% power. 4 passes @ 100 was the first to get through.
Check out the hole test too. Sub mm drilling is easy.
English
Got a new UV / MOPA fiber laser to play around with.
Exploring ways to build PCBs at home quickly.
Check out how incredibly well it removed the solder mask. It even exposed the FR4 fibers. 🤩
English
@JamesMcPherson Oh boy I was hoping for exactly that!
If we are able to remove copper with the UV laser we are so god damn back.
At what pulse width, speed and power were you going for that copper?
English
Oh yes, I could easily remove copper and make exceptionally accurate cuts through the FR4 or FR1. FR1 is the only one that works with MOPA at all, o I have a bunch of it while I tried and tried to get the MOPA to remove copper without burning the substrate.
With the xTool UV, I can be very precise on how much material I remove. I test with a VOM then do a couple of extra passes for good measure.
The holes I can drill are almost unbelievable.
English
@robin7331 Check out pcbburn.com, allows you to convert kicad files into laser paths
English
The only thing you have to do to switch from MOPA to UV with this machine is swap out the lenses.
It has an optical port on the back where you insert the MOPA frontend.
Pretty slick!
I only tried it for an hour but I was not able to remove any copper with the UV laser. Haven‘t had enough time to experiment with the settings though. You were able to do that?
English
@robin7331 The UV side is fantastic for PCB’s. I didn’t realize there was a combo UV/MOPA laser out there. I’ve got both in 2 machines and have really wished for a combo.
MOPA has been all but useless for PCB work, but obviously fantastic for metal.
English
@novadoesit Not really looking into making vias myself. I‘m experimenting with a different idea. More about that soon. Don‘t want to lean out of the window too far just yet 😁✌️
English
@robin7331 I heard it's possible to cook vias with it also, needs a plating process too of course. But nobody seems to be willing to share the recipe. Please let us know when you've managed to do it! 🧪
English
@robin7331 Wait, is FR4 woven?
I always assumed it was just cross laminated
English
@robin7331 The exposed fiber glass is awesome. I wonder if you can demonstate the fiber weave effect by unmasking some differential pairs, especially on non spread weaves.
Absolutely gorgeous shot
English
@xpguru3dprint The MOPA has 100w. The solder mask was removed with the 6W UV laser though.
English
@robin7331 Using cheap 450nm laser to make PCB's. Quick and less hassle then toner transfer or UV.
English
Making stencils is a priority for me, too. Got some scrap stainless stencils to play around with. 6W UV will probably not work and the 100W infrared will probably bring in too much heat. But I’ll test it!
Also bought some 0.1mm Mylar sheets to do some experimenting as a backup.
Will keep you posted 👍
English
@robin7331 gonna buy it after your video, I wana try making stencils please test if it works
English
@ivishaltejwani I just played around with it for an hour as it came in yesterday.
Will start properly testing it on Monday.
Making a YouTube video about all of this.
