gist-arduino-serial

Proof of concept for reading serial output from Arduino directly

Getting started

• Clone the repo
• Upload .ino file to Arduino (e.g. via IDE)
• Verify output is being seen via Serial Monitor in Arduino IDE
• Open terminal, listen to same port that Arduino writes to
  • tail -f /dev/ttyACM0 on Linux
  • May require more setup on other platforms

gist-conedown-sensor

Proof of concept (potentially final) files for ConeDown sensors

We're using force-sensitive resistors (FSRs) as sensors to detect presence on our dancefloor tiles. This is an integration between those sensors, an Arduino, and our computer

Getting started

This is a personal log of getting a Foursquare backup/export setup. It's intended to be a bit of a resource for those who are bridging between technical and non-technical

It's not super explanatory either though. If you do have issues, feel free to email me and I'll update it in fuller detail =)

We want to export our Foursquare data and make the switch to Yelp in 2019 We have lost faith in Foursquare being maintained on Android and thus discovery can only be done on Yelp As a result, we might as well consolidate the data

lib/templates

We've had trouble finding our paths for templates before. Here's a good StackOverflow on the topic:

To use this in practice, edit vendor/bundle/ruby/2.4.0/gems/thor-0.20.0/lib/thor/actions.rb to dump source_paths and file:

Example for table migration:

# Do you have a bunch of nested folders of images that you want to scroll through easily?
# Well this script is for you, it will take nested folders and symlink their files so they're easily scrollable
# It retains the full path so files which should be next to each other still are :+1:

# Exit under sane conditions
