I believe these are edge lighted acrylic panels. (https://www.instructables.com/id/Edge-Lit-Displays/).It should be possible to make the numbers with CNC in a transparent plate. Place these in IKEA Härliga glass domes. This gives even more of a Nixie look. Thin silver electric wires must be neatly concealed. And the EL wire must be made exactly to length.

I've thought about the additional wire, and my first design had an EL wire around the numbers.You can hear the relays switching. Not really loud, but you can hear them. Currently the hours are connected to relays. And the minutes are switched by triacs. This causes the clock to make a sound once per hour (I've ordered parts to replace all relays by triacs). This is a large clock. I did not want to bend the EL wire too sharply. The first triac circuit gives problems. Use the Sparksfun circuit instead.

There is a way to make this clock the half of the current size. This requires to remove the (colored) coating for the entire wire. This gives a "blue" EL wire with a diameter of about 1.2 mm.

Definitely a great idea to experiment with. Wouldn't be an idea to add a counterweight? This could give a better video, and it makes handling this spinner more easy.

Thanks for the corrections.I have considered using a Wemos (ESP8266). Each Led matrix uses 288 x 3 bytes, and the memory space for variables is limited. Updating the LEDs should be done by means of an interrupt. Otherwise, the display "freezes" for a while when retrieving weather data.

Great way to show the parametric feature in Fusion 360.

The most common fault is a wire break: This can be between the controller and the ESC, between the ESC and motor, and/or between the PDB and ESC.Is this a DIY quadcopter?

The music is from Youtube: Ambient, Reflections

There is a video in the last step. It's a little too dark, the LEDs give enough light. but it's hard to make a video under low light conditions. This video is taken with more light
