Picture of Watch From Metro - Last Light

Hello Instructables community.

I am a huge Metro fan and wanted to give back to the community so I've designed this watch.

Step 1: Step 1: Get Your Gear Together

Picture of Step 1: Get Your Gear Together

* 1 x "Blue LED"

*1 x "0.36 inch 4 Bits Digital LED Tube Module With Clock Display TM1637 Common Anode"

* 4 x "20mm m3 cheese head bolt/screw" (slice off at bottom of circuitry holder)

* 1 x "Arduino Nano or Pro-mini"

* 1 x tactile momentary switch"

* 1 x DS3231 Real Time Clock Module w/ I2C Interface"

* 1 (or many) x CR2032 Lithium Battery" (Last between 1 to 3 years)

* 1 x "3.7V 200mAh 402030 Lithium Polymer Li-Po Rechargeable battery"

Extra Materials you may need:

*3/32" drill bit

* 2.5mm drill bit

* M3 tap

* Chisel or sandpaper

Watch Straps:

* 2 x "25mm watch spring / bars / pins"

* "25mm Watch buckle" (one size smaller would be ok as well) "https://www.buckleguy.com/wb1002-watch-buckle-poli...

* "25mm Cotton Canvas Webbing Dark Olive Green"

* You only need the 3 (Arduino module, TM1637 Module, Real Time Clock ) for testing, all others are complementary.

Would be cool if you could get orange leds or put some sort of filter in front of red ones and fake glass so it would look like nixie tubes.

In good time in the coming months.
The led's on the watch are unlit yellow, which is standard for the Metro games.
I've also designed a new, thinner watch for the construct.
This is an slight improvement on GoryashchiyeKlyuchi design.
Yeah, i was thinking about yellow but wrote orange for some reason.
My idea was like GoryashchiyeKlyuchi's design but with plastic instead of epoxy.
I don't like look of naked led display.

The real-deal nixie watch would be roughly 2.2" thick.
The nixie clock that I currently have is around the size of : https://www.kosbo.com/clocks/in-17-nixie-clock.htm...
Thought I design a watch so that everyone to afford it.

Working on the 3d printed transparent cover for the watch atm. Turns out somewhat milky every time I change temps.
New pics of updates in a few days.
I like the design! Nice job on your 3D print designs :)
Thank you :D
