opennukit / Nukit-Open-Air-Purifier

Nukit Open Air Purifiers are Open Hardware devices for improving indoor air quality. They are designed to be used with North American standard HVAC filters and PC fans. They are often an improvement over commercial air purifiers as they are quieter per m3 CADR delivered, have a lower cost of ownership per year, and are easily repairable.

Wiring hints? #4

Very cool project. I don't have access to a laser cutter, but I do have a table saw, and I'd love to build something like this for dust management in my workshop—and It'll be good practice for when my commercial air purifiers eventually fail.

Also appreciate the README. Having links to parts is super helpful. And, I love that the README doesn't assume that the reader knows enough about woodworking to be confident doing a glue-up—or even that they have clamps. :)

That said, I could use an equivalent level of remedial hints when it comes to the electronics. I have super basic questions, like: how many fans can run on a single power adapter? Assuming the answer to that is more than "one", are there connectors to chain them, or do I bust out electrical tape and wire the fans together directly?

👶😂 (I did build a few PCs for work once, but it was... 1997, I think, and I just bought what the nice people in the computer store picked out for me. Even if I remembered any of that, I'm sure it'd be obsolete now.)

If you click to the 4th picture on the amazon page for the fans, LINK, it shows the daisy chain feature on these fans. 0 wiring experience required to just daisy chain them, out of the box

The 12v unit linked should also be fine for such a load, I'm building this very soon and I'll update if I have any issues with the linked power supply
