Just wanted to share my very first hardware project and my first fabricated PCB.
There are some minor issues like pot orientation, but overall it turned out pretty nice (for a beginner).
This awesome! And thank you so much for sharing.
I really like this idea of a “Pod-expander”. I can imagine there being various expanders for different components and swapping them around.
Version 2.1 is here with header/pot orientation fixes. Plans for the next version include 8 pots and 8 buttons.
Wow! Nice display. Kudos @KnightHill !
I would change that to an expander board with a generous helping of pads available for mounting encoders, switches, an oled or two, a joystick, etc.
An individual could choose to populate a given part or not depending on their needs. And you might be able to arrange some of the pads so it could have a choice of parts to keep the board frpm getting too ridiculous in terms of size - you could have eight encoder and eight switches or 16 encoders, etc. - including things that could be mounted instead of a display. That way you could get some different uses out of a single board.
This is awesome!!!
I like the idea. However, what could be done is quite limited by the number of pins exposed by the Pod. I am reaching a point where it looks easier to design a Pod-like board with the configuration that I want instead of further pushing the Pod expander.
The next variant (below) is probably going to be the last before designing a Daisy board from scratch:
This all turned out amazingly!
It’s been awesome seeing the evolution of this project!
The latest iteration (I2C display + MIDI OUT) was a failure. A couple of observations:
- I2C displays are painfully slow compared to SPI. Definitely not something that can be used for real-time processes, like oscilloscopes
- It looks only pins D13/D14 and D29/D30 can be used for MIDI In/Out via USART. None of these is exposed by the Pod. My plan to use pin 9 failed miserably
SPI and I2C expanders side by side:
Doesn’t the pod already have MIDI via a TRS cable?
Pod has MIDI IN only.
