# Reproduciblebuilds Status Display

This readme describes how to create an acryl laser engraved logo which fits in

a wooden lasercut case with integrated neopixel leds for an awesome effect!

# Requirements

The case and acryl are both made with a laser-cutter and apart from that some

soldering is required.

* esp32 in a small form factor

* acryl (cast preferably)

* wood suitable for laser-cutting

* six APA102 neopixel leds

* wires

* hotglue / woodglue

# Flashing the ESP32 (pico)

The ESP32 first needs to be flashed with

[micropython](https://micropython.org/download/) following the instructions on

their website. After a successful installation opening the esp's serial port

with for example screen should provide a Python interpreter. A tool called

[ampy](https://github.com/pycampers/ampy) can be used to copy the two Python

files to the esp32. Simply execute ```ampy -p /dev/ttyUSB0 put pythonfile.py```.

The file called ```boot.py``` will be executed on boot, and in the current code

it then goes into a deepsleep after which it executes again. This makes it a

bit more difficult to update the code, since ampy does not seem to be able to

interrupt the deepsleep or reset the MCU, the easiest way to update

```boot.py``` is replugging the esp32, opening screen and pressing ctrl+c to

interrupt the boot code so the esp32 does not go to sleep. Then ampy can be

used again to upload a new ```boot.py```.
