Welcome to the Analog Terminal Bell!
The Analog Terminal Bell is a bell that rings any time a bell character is displayed on your terminal. Simply plug the bell in to USB and enable "Analog Bell" in your terminal settings.
Never miss a terminal bell notification again!
Here is a photo of the bell:
Here is a video explanation:
This bell is not actually for sale. You have to build it yourself! This project uses an MCP2221A microchip to drive a solenoid and hit a bell.
Information about the electronic hardware to build this project can be found in
the pcb folder. Just check out the README there for details
on how to build the electronic hardware for this project.
I used through hole components on the PCB to make assembly as easy as possible.
The bell can be found at many stores like amazon or staples
Unlike an Arduino, this microchip doesn't need any firmware, we can control it
via USB HID. See the README in the software folder for
details on how to control the bell from your computer.
Note that if you want iTerm2 to ring the bell like in the commercial, you'll need a custom build of iTerm2. You can find the patches for iTerm2 here.
The case is 3D printed and the stl files can be found in the case folder.
