Desktop Blinky DND Box

UPDATE 2019-Jan-30 -- fixed misplaced counterholes for the wood screws.

This is an Arduino-Nano-powered desktop "Do not disturb" sign for those "I’m busy, leave me alone" moments at the office. Press the top front, and it switches between a faint standby mode "breathing light" and various selectable light effects.

Color and effect are configurable with two analog potentiometers so they'll maintain the setting without requiring flash storage.

Components:

Arduino Nano Clone

Pin headers

2-pin and 3-pin connectors

5x7 cm perfboard

WS2812B 8-LED board

2x 50 k linear potentiometers

Push button 5x5 mm

Resistors: 1x 10 kOhm, 4x 560 Ohm

1N4001 diode

Wire

MicroUSB breakout board for 5V power supply

Two small wood screws

Printer:

TronXY X5S

Rafts:

No

Supports:

No

Resolution:

0.6 mm nozzle, 0.2 mm layer height

Infill:

10% hex

Filament:

White/Black

Notes:

The overhang of the "fin" that pushes down on the mode button may be problematic and require supports turned on. I printed without and needed to clip/cut/saw some of the drooping edge to make it fit.
