Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

[WIP] PhotoLife - Conway's Game of Life, in a Photoframe, on an Arduino Nano, using 12x MAX7219 blocks in a 3x4 array
What's cool about this project is that the array of MAX7219 blocks are not arranged in the usual long line but in a proper rectangle. Github user matdombrock modified his MatrixGL library just for this purpose. https://github.com/matdombrock/MatrixGL/

MatrixGL - An Arduino Graphics Library For LED Dot Matrix Displays
Why don't you submit an issue on GitHub and I'll see about getting support for this setup. https://github.com/matdombrock/MatrixGL/issues

Ask HN: What are you working on (August 2024)?
I built a midi controller. Rather, I repurposed a Teensy-based virtual analogue synth I made ages back that never worked quite right. I had taken the amp/speaker out to use somewhere else, and it was just sitting in a box. I realized I could just use the Control Surface library (https://github.com/tttapa/Control-Surface) and change it to a midi controller in no time flat, so I did. Now just need to get some time to use it to play with VCV Rack.

Just got an Arduino kit, what are some simple projects that would help me learn coding and be useful with my modular synthesizers?
I was in a similar boat to you, though I have a lot of experience programming outside of the arduino/midi controller context. I was pretty happy to just use https://github.com/tttapa/Control-Surface as a library to handle connecting an arduino with a pot to my PC as a midi controller. The docs and examples the codebase has were very useful.
- I think this relates to this sub as it is controlling a synth and I need all the help I can get tyia

DIY Midi Controller
Wow, what a pretty project! If you end up expanding this, you might look at the Control-Surface lib; seems like it's made for this kind of thing.

Ask HN: Unconventional Use of MIDI?
https://github.com/tttapa/Control-Surface
I've been working on this beasty project together with a friend. We did some liveshows back then and decided that we needed some more control gear. But not just a laptop focusing launchpad, we wanted to forget there was even a laptop (or other hardware) attached to this controller, so that all our attention and focus would be on the music and the crowd, and above all: we wanted something that would instantly announce your presence on stage.

CC midi controller with approx 37 knobs!?
I used this library with an Arduino and several multiplexers. It worked very well and was easy to use. https://github.com/tttapa/Control-Surface
- Hello my fellow logic lovers, I have a question. What is the best DAW-Controller for logic, or would you recommend getting an iPad and using logic remote?

teensy 4.0. I think I have a debounce issue. I don't know how to add it to my code.
Should be fixed in https://github.com/tttapa/Control-Surface/commit/eb7a468a0a73584b93be16d978404b25401ce66f, you can increase the SELECT_LINE_DELAY constant if necessary.
- How do I essentially go from button to sound?

My open-source synth/sampler/sequencer/DAW-in-a-box: The LMN-3
The PCB was an entirely new endeavour for me, but it was essential in making the project footprint as small as possible. Never done any kind of electronics design outside of hobbyist arduino stuff and the initial prototype. I used [KiCAD 6] to design the PCB. KiCAD might be the single greatest GUI-based open-source software I have ever used, its a shame FreeCAD is so far behind it in terms of stability. It is also free and open source. I went with a simple 2 layer design with all through-hole components to keep things as simple as possible so people didnt have to mess around with heat guns or toaster ovens to solder the board. It turned out great. I also elected to use a teensy to do the heavy lifting. Sticking to an arduino platform means its a lot easier for people to contribute to the firmware. It also meant I could use the greatest arduino library ever written, Control Surface. Control surface is what makes it so easy to write the midi logic for the firmware. It is the backbone of the firmware and really is incredible.
