3D Printed Seven Segment Display

This project collects the build details for a custom 3D printed seven segment display. The segments are illuminated with "Neo Pixels" (SK6812 or WS2812) driven by an Arduino-compatible based on the ATtiny85.

Printing

• Printing: Anycubic i3 Mega
• Slicing: Ultimaker Cura 3.6 ** 0.1mm layers ** 20% infill ** EO temp.: 200C ** Bed temp.: 60C

BOM

• Digispark ATtiny85 rev. A
• SK6812 neo pixels
• wire, solder, etc.

Notes

• Arduino 1.8.7
• Digispark programming ** on Ubuntu 18.04 LTS ** follow their guide on setting up udev rules for the USB connection ** tested with blink (found LED on pin 1: model A)
• should be able to get it to look like a Trinket, but no progress there
• future idea would be to figure out how to get an updated micronucleus bootloader on the ATtiny85 and switch over to AVRDUDE
