Project by Matt G. Galveston, Texas.
Here is my second project for the Phase Dock system. [See Matt’s first project. A ferrite core memory read/write]
It’s a DIY prototype audio preamplifier with simple filters for tone controls. It also has a bar graph using a 3914 chip and 10 LEDs.
You can see that I have 3D-printed several brackets to hold input and output jacks and potentiometers. These brackets are easy to design (I use OpenScad) and are attached to Phase Dock Clicks using superglue. Once you have one workable design, modifications are easy to make to accommodate different components. These really help with keeping external interfaces clean and are readily reused.
This is Matt G’s project and his write-up. Barbara is just the webmaster. :-)
