3D model description

Inspired by the LAMetric display, I have build my own LED display with bluetooth control using a 32x8 LED Matrix and a cheap arduino nano board with bluetooth (Bluething).
It also works with other arduino board + additional bluetooth module (e.g. HC05).

For manual operations, the clock can be controlled with a rotary wheel. You can choose between the following functions:
-clock
-timer/countdown
-stopwatch
-alarm
-display custom text (scolling)
-options

To keep track of the time/date I use a simple DS3231 RTC module .
An active buzzer is used to do the alarm.
A rotary encoder is used to toggle through the menu and select entries.

The 3D printed parts are:
Enclosure
Wheel
LED Grid & shade

More details will be published on http://www.dietzm.de
