The second prototype of the Aether 3D printer air filter is assembled. On the upside, it works. There are a few issues that need to be fixed, but these are mostly due to tolerances around the sensors, and the magnetic fixing mechanism.
Things we will improve:
- The HEPA and, active charcoal filter cover needs some additional tolerance review, so it is quicker, and simpler to use.
- We are re calibrating the sensors for this case (prototype 1 was a very crude mockup, with a different flow configuration).
- We are also figuring out the ideal RGB feedback colour.
- Improving the controller board, especially the 12V boost converter.
Firmware:
We are also working on the protocol for communicating with the printer. Right now it’s a simple high-low binary communication, but we intend to create one that gives us more flexibility. This is not an easy task, as we have to make sure it works with most 3D printers, with only GPIO pins exposed. Right now, we expect it to be something pwm based. We will make both versions downloadable after the Aether is available.
Other changes:
We are removing the stand of the Aether, as it seems to be unnecessary. It will be downloadable from the site after the filter is launched, should someone wish to still print it.
