Captures everything needed to redeploy the two-display clock (hour on I2C 0x61, minute on I2C 0x63) on a fresh Pi: - Both systemd units (matrix0x61.service, matrix0x63.service) - Deployed Pimoroni script tree, including the local %I (12-hour) clock customization - Vendored upstream sources (ltp305-python, breakout-garden) so restore is fully offline-capable - Boot config snippet enabling I2C - install.sh that wires it all back up idempotently - Inventory doc cross-referencing every live-system path Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# Seismograph example
|
|
|
|
The Dino-Detect v1.2 beta is a dino stomp detector. It's a
|
|
UNIX system, I know this.
|
|
|
|
## Pre-requisites
|
|
|
|
This example requires:
|
|
|
|
- A Pimoroni [Breakout Garden](https://shop.pimoroni.com/products/breakout-garden-hat-i2c-spi)
|
|
- A Pimoroni [LSM303D 6DoF Sensor Breakout](https://shop.pimoroni.com/products/lsm303d-6dof-motion-sensor-breakout)
|
|
- A Pimoroni [1.12" OLED Breakout (SPI)](https://shop.pimoroni.com/products/1-12-oled-breakout)
|
|
|
|
## Installation
|
|
|
|
Pop the breakouts into your Breakout Garden, and then run the `install.sh`
|
|
script in the root of this repository with `sudo ./install.sh` to automagically
|
|
install the libraries to run the I2C breakouts.
|
|
|
|
For this example you'll need to make sure some additional software is installed:
|
|
|
|
```
|
|
sudo apt install python3-pil
|
|
```
|
|
|
|
You'll need to clone and install the library for the 1.12" OLED Breakout (SPI)
|
|
as follows:
|
|
|
|
```
|
|
git clone https://github.com/pimoroni/sh1106-python
|
|
sudo ./install.sh
|
|
```
|
|
|
|
This example assumes that you have the OLED plugged into the front slot on the
|
|
Breakout Garden HAT, which should also work with the Breakout Garden Mini HAT.
|
|
To change it to the back slot, change `device=1` to `device=0` on the line
|
|
where the OLED is set up.
|
|
|
|
## Running this example
|
|
|
|
To run this example, type `./seismograph.py` in the terminal.
|
|
|
|
Note that it takes a baseline reading initially to zero out the axes,
|
|
and then calculates subsequent readings against the baseline, so make
|
|
sure that your Breakout Garden is sitting still when you start the
|
|
program.
|
|
|
|
The `sensitivity` variable can be changed to make the seismograph more or
|
|
less sensitive to dino stomps.
