This directory contains the PCB design for the analog terminal bell.
The PCB is designed using KiCad. If you don't want to deal with KiCad, it's no
problem. Just upload the gerbers.zip file to any PCB manufacturer and you
should be on your way!
Here are the components needed:
-
Mini USB B Connector ($1.72)
-
10k resistor ($0.10)
-
1k resistor ($0.10)
-
47nf capacitor ($0.22)
-
1N4004 diode ($0.12)
-
TIP 122 or 102 ($0.70)
-
Solenoid ($4.95)
-
MCP2221a ($2.27)
-
JST connector ($0.17)
-
14 Pin Socket ($0.18)
-
Bell ($7.99)
The electronic components for this project should cost around $11 (before shipping, taxes, etc).
All of the components go on top of the board, except the USB connector. The USB connector goes on the bottom of the board!
