Made several updates to my modular-electronics project (full explanation in comments) from electronics
I’ve posted earlier versions of this experiment (I call it “Project Pockit”) on this sub, and got some useful suggestions.
So wanted to post a demo of the newest version. A lot of possibilities have opened up with recent upgrades that I made (e.g., a new approach to side-attachment of blocks).
Here is the [full video with explanatory narration](https://www.youtube.com/watch?v=b3F9OtH2Xx4).
And the project details/timeline [are here](https://pockit.ai/index.html).

Overview of the project:
To speed up my prototyping, I made several modular PCBs, each with one function and following a universal connector format — matching a base Core board which provides a grid of connection points.
Then, I added 3d-printed housings (with reopenable snap-fits for easy modification of the internal circuits) on all of the blocks, for protection + aesthetics.
The Core board is based around an STM32F4, and an optionally attachable Pi Compute module for more intensive use-cases (some of which are demonstrated in the above video).
So the connection “slots” on the Core board essentially act as breakouts of the processor pins. Each slot includes shared buses like SPI and I2C, but also some unique GPIO, ADC, and other signals.
The electrical connection of the blocks is accomplished using spring-loaded pins (“pogo pins”), while neodymium magnets are used to create mechanical attachment, which I’ve tested to be *way* stronger than what I typically need for prototypes.

Been a long journey on this project, and satisfied with the results, but hoping to make further firmware refinements, especially for the adaptive behavior.
Happy to answer any questions from you guys, technical or otherwise! Also, open to hearing any constructive suggestions like in the last post.
This is amazing! Great job 👏
Seriously. Great job.
That’s pretty goddamned impressive
I hope you firstly patented this or did something, because this would be a great business idea. THE PROJECT LOOKS F*ING AWESOME!
