@sdetweil Huh. Well, that’s new. If I ever get around to making the hardware accelerated version I’ll give it a go.

@sdetweil Now this sounds interesting. Do you have tutorial or URL where I can learn how to set this up?

@Syosse said in MMM-Globe rotates very slowly and haltingly:

So is there no other solution than replacing the Raspberry Pi and getting one with a higher CPU?

You could finish what I started. Write a module that uses the 3d-accelerated globe libraries. There’s already a project out there that has the hexagon look & feel.

You’ll have to reconfigure your mirror to use Chromium in kiosk mode to display your mirror, rather than the default Electron (Electron does not support hardware acceleration). That’s not difficult at all. It’s just command line arguments. That should work on an RPi.

@Tippon Yeah, that’s pretty much it. The mirror attempts to connect to my command & control server at DNS entry that I control. When it connects, it establishes a reverse SSH connection. I can ride that reverse SSH connection down into the mirror. The C&C server is cloud based, so I just turn it off whenever I don’t need to connect to the mirrors.

Because it’s the mirror making the outgoing connection, firewalls let it pass by. All the mirror needs is a connection to the internet.

I have a pretty long tutorial on how to set it up. I’m a bit verbose.

@Syosse - The reason for the slow & flashing is because that module is pure Javascript and doesn’t use hardware acceleration at all. It’s using the CPU to do all the work.

I’ve been toying around with a 3D accelerated version of that module but I got distracted. It didn’t look super hard. Mostly just playing around with some free libraries.

@BKeyport - Hrm. Well, whatever the issue is, it is apparently only affecting me. I have a workaround, so I’ll manage.

@sdetweil - Do you think there would be any benefit to running the mirror in server only mode and using Chromium or Firefox in kiosk mode? It may succeed where Electron fails.

@sdetweil - I ran into the same problem on Firefox. I conclude that it’s not a browser issue. It seems to be a file issue. I can upload JPG but not PNG. That’s easy enough to work around.

“Any sufficiently advanced technology is indistinguishable from magic.” – Arthur C. Clarke

Many years ago, I went to a very small school and I’ve stayed in touch with most of the people from that class. One of my friends is now a parent with kids in that same school and heavily involved with the PTA, school clubs, etc. Each year, they host an auction to raise funds for the school sports & drama programs and she asked if I could donate a magic mirror for the auction. So I came up with this:

The theme is the use of technology to give the appearance of magic. The left side of the face has various equations & graphs, while the right size has some wiccan & magic symbols. The words are carved with my CNC and filled with a 2-part resin with metallic pigment.

It’s running on an RPI4 with the camera module and a PIR sensor built into the frame. There are 300 neopixels running around the back side of the frame, but I didn’t quite have time to get that part of the mirror working before the auction. It has my reverse SSH code on it, so I can get into it remotely now that it’s been auctioned off.

Honestly, there are several things I would do differently if I had more time (I’m a terrible procrastinator). It needs engravings on the top & bottom pieces of the facing frame, not just the sides. And the pigment for the words should be darker, I think. If I can convince them to give it back to me for a couple weeks, I may be able to redo the frame properly. And I really need to buckle down and get the neopixels working properly.
