Projects & Workshops

Make-a-synth

Workshop led by Seth Jayawardane

The first hour or so was spent going over how exactly the synth works on a basic level as well as building the synth which mostly involves correctly wiring buttons on a breadboard. The next hour was spent helping some people debug why exactly their synth did not work since there are some common mistakes that are typically made as well as people spent this time using their functioning synths to play different beats. In the end, everyone interested tried to make a short 15-second beat and offered a prize in the form of free filament to whoever comes up with the best beat.

Puzzling

Workshop led by Seth Jayawardane

In this workshop, we showed students how to make their jigsaw puzzle using freely available online generators and cut the pieces out using our laser cutters. We had a great turnout and had a blast seeing all the cool puzzles everyone came up with. Take a look at some of the puzzles made by makerspace users!

LED Sign

Project Marcus Montisano

This project uses a custom Stream Deck plugin to communicate directly with the Adafruit IO REST API. It works by posting a specific value to a feed and each button will post a different value to the feed allowing you to easily change messages.

The message panel itself is driven by the Metro M4 Express Airlift Lite. It will connect to local WiFi and read the value of the message straight from your feed. It even allows some basic formatting such as color and text size. The feed values are limited to 50 characters, so the more formatting you apply, the less text you can show. Fortunately, the message panel can hold a maximum of 40 characters.

Parts:

Adafruit Metro M4 Airlift Lite dev board with SAMD51 an ESP32 Wifi Co-processor.

Adafruit RGB Matrix Shield for Arduino connected to a LED Matrix that reads “Adafruit Industries LED MATIX! 32×64 RGB”

64×32 RGB LED Matrix – 4mm pitch

5V 4A switching power supply brick with figure 8 power port.

pile of 50 Brass Heat-Set Inserts for Plastic – M3 x 3mm.

Wireless mechanical keyboard

Project by Xudong Zheng

Xudong was able to use the laser cutter to create his ErgoBlue, a Split Wireless ErgoDox Mechanical Keyboard. For more information on this project check out his website: https://www.xudongz.com/blog/2019/ergoblue/

Benchtop Power Supply Enclosure

Project by Gavin Granath – ggranat1@jhu.edu

Gavin was able to purchase an inexpensive DC power supply from ebay and then design and print his print his enclosure in the Makerspace. With accurate voltage and amperage control, benchtop power supplies make it easy to test and prototype electrical components.
