LED Sectional - Program Arduino

This guide is an improved version of Kyle Harmon's Guide to programming the LED sectional. This allows you to update WIFI info, change airports and change the lightning or high wind behaviour.

A. Download Arduino

1. First Download the Arduino IDE: https://www.arduino.cc/en/software
2. Once you've opened it, paste in the code linked below in 02-led-sectional.ino

That's it! We'll talk about how to update the different parameters after we've installed the dependency libraries.

Run out of EBS space on an ec2 instance?

1. Make sure the instance has arn:aws:iam::aws:policy/AmazonEC2FullAccess permissions.

2. Create a script called resize.sh with the following contents:

#!/bin/bash

# Specify the desired volume size in GiB as a command line argument. If not specified, default to 20 GiB.
SIZE=${1:-20}

Disable Protected Mode in AWS ParallelCluster

If your cluster tries 10 times to launch instances and fails, it'll automatically go into PROTECTED mode. This disables instance provisioning until the compute fleet is restarted.

You'll see inact as the status of the queue when the cluster is in PROTECTED mode:

[ec2-user@ip-10-0-0-98 ~]$ sinfo
PARTITION AVAIL  TIMELIMIT  NODES  STATE NODELIST
default* inact infinite 2 idle~ spot-dy-compute-[1-100]

🚀 Wifi

So naturally the first thing I wanted to do when we got fiber internet was to rename the wifi network to something sexier than "CenturyLink0483". I decided on 🚀.

To do so I navigated to the router setup page at 192.168.0.1, cringing with all the 90's tech it employs.

Then I added 🚀 and tried to update.
