Creative Upgrades

It”s finally here! For Christmas as a gift to ourselves, we decided to upgrade from our XYZ Davinci Jr. 2.0 Mix to a Snapmaker 2.0 A350.

The original printer we have is good, but it”s got a very small build area for some of the things I wanted to design and print. The color mix option is really cool. But it”s biggest faults are the NFC chipped filaments that are required for use, and the software to slice the prints.

The NFC chips are a neat idea, they pre-set the heating information and keep a loose track of how much filament is supposed to be on the spool. However, if you try to load filament that isn”t chipped, then it won”t print. You can just mount a pair of chips to it, after removing them from the spools, but then you have to deal with the persistent warnings that your spools “are most likely empty”.

We”ll still keep it around, but it”s time to upgrade.

Enter the Snapmaker 2.0 A350, a nice large 3-in-1. The build area on this thing is HUGE compared to what we had before. Assembly wasn”t too bad, leisurely got it into a running condition in about an hour.

The initial calibration took a few tries after the firmware upgrade, mostly because I”m used to dealing with a nozzle that”s a little larger. The nozzle on this is VERY fine.

Currently my first print is chirping away on the print bed as the actuators move everything around. Yes, it”s very very chirpy.

Looking forward to all the projects this new system will able to make happen!

Conference Pi

Idea:

Use a Pi hooked up to the living-room TV with a webcam to make family and group video calls easier to manage without having to frequently rearrange computer locations.

Parts:

  • Raspberry Pi 4B 8G
    • Ubuntu arm64 w/Xubuntu Desktop
  • HDMI to miniHDMI cable
  • USB-C power adaptor
  • Webcam
    • USB Webcam
    • Pi Cam
  • Connectivity Options:
    • External keyboard & mouse (less optimal)
    • VNC (doable)
    • Barrier (preferred)

First off is the microphone enabled USB Webcam.

Update:

So close! The webcam was seen, the mics picked up sound from across the room just fine, everything was beautiful on the initial tests. That is until I joined a google meet. Video both directions were good, but the Pi began to choke on the audio processing. No sound in or out.
