I already own some real nixie clocks and so want to have a lixie looking and acting as similar as possible like the nixies.
So, based on Folkers lixie digit, I created digit positions for colons and used an ESP8266-Module ESP-12E for control to have a webinterface, can retrieve the time over NTP (no separate RTC-module necessary) and to be able to realize a smooth digit change.
Additionally I created connectors to connect the digits and endpieces to let the sides look better.
For the digits itself I used cast acrylic because here the engraved lines are more frosted than in extruded acrylic and the numbers become brighter therefore. Unfortunately cast acrylic has massive thickness tolerances. So my acrylic sheets are between 2.2 and 2.5 mm thick instead of 2.0mm. Ofcourse these digits did not fit into the shades. So I added different shade-plates with wider holes to be able to use these number plates.
The engraved lines looks better if they are engraved from the back side of the plate. So I mirrored the numbers to do that.
The current state of the firmware and the webinterface and its usage is to see in this video: https://youtu.be/9bHxMQD_vJw
The firmware for this clock is available on github: https://github.com/xSnowHeadx/lixie (in german too, sorry)
The software allows to use the clock without colons. If you don't use colon digits I recommend to use the wider connector variant at the colons positions to optical separate hours, minutes and seconds.
For the parts with 4mm thickness I used two stacked parts cutted out of 2mm sheets. So the edges look better.
in the same manner as loubie (https://www.thingiverse.com/thing:1350837) I found out that hundreds of models from thingiverse are sold on ebay ignoring the CC license the models were shared with here. https://www.ebay.com/str/3D-Pyro-Prints
The Vero-Team from ebay does neither accept thingiverse or makerbot as a legal corporation nor the CC-license as a justiciable license.
Thingiverse itself also declines to give the members support to enforce the rules of the CC and recommends only to continue the ridiculous and useless dialog with the vero-team and the parasitive sellers or to contract a own lawyer to stop this sellers.
In fact the CC is not worth the click to select the right type for the shared models.
So I'm forced to remove all my models here. I'm not willing to waste my spare time for the profit of these antisocial parasites.
If you are interested to get the models files contact me please. If you are an active member here and shared own models here I would be very glad to send you the files.
