Mark Gibson presented a Pinball Engineering workshop on Mar 9, 2018

Workshop started with some time for students to play the pinball machine and familiarize themselves with its features and objectives which should provide some context for explanations later in the class. Then with everything turned off, we went through a short summary of electric current, switches and magnetic fields to explain basic Boolean logic and how relays and solenoids work. Using those principles we explored working examples (flipper, pop bumper, etc.). Then we opened up the pinball machine and explored how various parts of the game work using the ideas we’ve covered.

ATLAS Light Tower Hacking


Slaton  Spangler (  said (on Dec 8, 2017):

I recently finished an internet connected controller for the ATLAS Tower lights.
Mess with the lights here:
(It might take a second to load)
And check out the documentation for integrating the tower into projects here:
Make something cool with it!

BTU <3 Sparkfun Thank You Sign!

In order to thank Sparkfun for generously sponsoring the BTU Lab, I created an internet controlled sign for their office.

The sign is controlled by a large red button, which resides in the BTU Lab. When the button is pressed, the sign’s heart lights up and blinks!

The sign is controlled by Particle’s Photon, and the button is controlled by Sparkfun’s very own Thing!

Here’s a video of it in action

And here’s the code/schematics:

Jarrarium – Part Jar, Part Aquarium

Inspired by the many posts at /r/jarrariums, I put together an aquatic jar for my desk here at the BTU, along with an Arduino temperature readout!

Water in the jar gets replaced every other week or so from my aquarium at home. The current inhabitants are two bits of Water Wisteria, a small bit of Amazon Sword, and a Nerite Snail!

The temperature readout is just an Arduino (really, a SparkFun RedBoard!), a DS18B20 Temperture Sensor, and an LCD screen. I’ll add a Fritzing diagram and code snippet soon!

For now, here’s some pictures.
