thingiverse

This is my take on Artyom's Watch during Metro - Last Light. ~ Since I didn't get the 1 in 10 Metro Exodus Artyom Edition. >.< * Print out the Glass Tube in clear filament if you can, or cut to length a frosted bic pen tube. Go to "https://www.instructables.com/id/Metro-Last-Light-Watch/" to get full progress. Still in beta process. Electronics: * 1x 0.36 inch 4 Bits Digital LED Tube Module With Clock Display TM1637 Common Anode * 1 to 2 x blue leds * 1 x opaque bic pen (the casing you need for led housing) * 1 x Adafruit Micro-Lipo Charger for LiPo/LiIon Battery with MicroUSB Jack - v1 * 1 x 3.7V 200mAh 402030 Lithium Polymer Li-Po Rechargeable Battery * 1 x Arduino nano or Arduino Pro Mini (depending on size of case) * CR1220 Lithium Battery 3V Button (1 to 3 years of service time) * 1 to 2 x momentary switch Items needed: * 3/32" drill bit to ream out the 8 holes. * 2.5mm drill bit + m3 tap * 4 x m3 machine screws, snipped off just under the circuitry holder. Optional: * Chisel for edgework to make the circuitry fit in. * Gluegun if your chiseling is not solid. * Sandpaper for finish up. * Bondo or PVC spray-paint to hide the flaws. * Paint to hide the evidence. * Rub-N-Buff to add complexity and age. * Flaunt it to show your a bad-a$$ * Use it in conjunction with your bullet lighter to see your way into the dark tunnels. *Or* You can upload it to Shapeways and forget about it. *Note: Opening below the led housing is for resistor if you please. Is a force fit and the strap holds it together.
