MTA Train Times Display

Displays upcoming train information in minutes to a 32x16 RGB LED Grid

Setup

• get a free MTA developer's API key
• add network name and password to recipe.xml between the ** symbols, removing the ** symbols
• flash SD card to full raspian using PiBakery and recipe.xml
• make sure the Pi has an uninterrupted power supply the first time it boots up, so it can install and set up everything it needs to, then you can ssh pi@trainpi.local, password will be goodtimes unless you change it
• connect the pi to the MPC1073, connect the MPC1073 to the HUB75 LED matrix

Cron

• schedule cronjob to get train schedule every 30 seconds, and render upon boot

BOM

• Raspberry Pi or Pi Zero with Hammer Header Male Connector, and power supply
• MPC1073 and CR1220 battery
• 16+ GB SD card, and card reader / writer
• 32x16 LED matrix with ribbon and 5 Volt 2 Amp power supply
• Female DC Power adapter - 2.1mm jack to screw terminal block to go in back of the LED Matrix

Troubleshooting

• wait at least 2 minutes after powering your pi with the LED display for the train times to appear
• after plugging in a pi with a freshly baked flash card, wait at least 5 minutes
• to see if program that renders the train times to LED display is running, ps aux | grep demo
