Ocreeb MK2 is the second iteration of my macropad project. This version features the XIAO RP2040, hotswap sockets support, a detachable switch plate, an OLED screen and I'm exploring a fun new idea inspired by the Monogram Creative Console - a custom magnetic connector that lets me attach all sorts of external modules to make different layouts. Join me as I try to design and build the modular macropad system that kind of works 😅

Regarding your performance issues: you may be able to speed things up by writing your signal interpreter in C and compile to a dynamic library (.dll on windows, .so on *NIX). Using the Ctypes (uctypes in circuitpython) module , you can import it as a python module and call your functions while benefiting from C-level performance.

@salimbenbouz 4 месяца назад

Thanks for the suggestion! I will look into it. You're right maybe this will work way faster for the custom address pulse I was tinkering with.

@Debrugger 3 месяца назад

Dynamic libraries aren't a thing for circuitpython (a loader probably wouldn't even fit in memory). You need to statically compile it into with the runtime. I couldn't find any up to date guides, but I think you just have to copy what the other modules in `circuitpython/shared-module` do.

@witebatman 4 месяца назад

Dude, I am blown away by your creativity and technical follow through. Huge inspiration. Thank you!

@silardgal8223 3 месяца назад

The interrupt fix can be that you buffer data on the module side. Meaning if there is a press, you put it into a buffer, and when the main modules comes to read it, you are not losing any data. Yes, you will have a small delay, but still with no data loss. I would suggest the next version to have CAN Bus, as its a multi-master system and you can send messages directly to the main host, but also to the modules as well. Awesome project!

@giannismentz3570 6 дней назад

The CAN Bus protocol might be appropriate actually for this project, I had read a bit about it in the past, yeah it's probably the right choice. Your buffer fix will probably also do the trick as well, if he doesn't wanna go the extra step and add CAN Bus to all this.

This project looks absolutely cool! The modular idea is really great and makes it easy to experiment with different modules. This could be really interesting and helpful for beginners. It's also nice to see someone showing the problems that occurred while making the project. You often see such great projects with no problems whatsoever. And if you try to make it on your own it doesn't work as easy as it seems on other videos. Really great! 👍

Will 100% be adding this to my list of future projects. I had the OG Pallet Gear before they changed to Moment and I loved how it worked. Design(s) look beautiful and being able to have those hotswap keys so if I am working in a shared space I can have quieter keys or if I decide to use it for something like gamin I can have a more tactile or clicky key is just genius.

@danfg7215 4 месяца назад

I say forget magnets, they're clever, but I'd rather have a physical lock under the pieces to securely keep them together, maybe a slide mechanism or like legos. Realistically, users will setup the parts once, and rarely move them around. Just my two cents on your amazing idea.

@martin_mrwld 4 месяца назад

I think it should be combined with gridfinity

@Savannah-sd 4 месяца назад

Sounds like someone's never used magnets nor a modular platform before. I say you teach yourself some things before you start spewing nonsense. When you do actual work using inputs that aren't a basic keyboard, your setup will evolve as your workflow evolves, literally the entire point of a modular setup, and modular setups are rarely setup and never changed. As for your issue with magnets, you clearly have no basis in reality for that statement, neodymium magnets are more than strong enough for this application and the modules aren't just going to break apart as you use them, not that they even would break apart without intentionally separating them anyways given that they'd only realistically separate under linear opposition as there's no point in the mechanism to skew along the other axes. You clearly lack the capability of logical thought given your stance on this, and you clearly base your stance in combination with lack of logical thought on your lack of experience with anything relevant here considering your lack of understanding. If you choose to be this mindless, then learn to sit down and shut up instead of spewing your mindless shit.

@helplmchoking 3 месяца назад

A magnet might not be as strong as a slide lock or lego style stud (which is much harder to disconnect), and I'd personally love some kind of push latch mechanism so you're not sliding on pogo-pins but anything mechanical is going to be a potential breakage - especially with brittle resin printed parts. The magnets might be less secure but there's no sliding pins against each other and no small parts to snap

@chybanie716 24 дня назад

Man, I love your content. This video was suggested to me by the algorithm and I clicked it because it is a very specific topic that is of interest to me but also I vaguely remembered watching your video about the first macro pad. As usual when someones content impresses me I checked out your channel and my mind was blown - "omg, it's the same guy that made the DIY space mouse" I thought as I had that video in my 'watch later' for some time now but never got around to actually watching it. Well, now I got around to it as my adhd brain hyperfixated on learning Fusion the last 3 days and already wants more control so it was a perfect combo. In that video I noticed your CRT Rapsberry so naturally I had to watch that video as well and was impressed as well. Your workflow is great and you do a great job presenting it. As well as documenting it on instructables and github? I must be dreaming :o Do you have a background in design? You pay attention to details, your creations are great in function but visually beautiful as well. The idea with a PCB as a front plate instead of a sticker was amazing. You really are an inspiration for me and my projects!

I sketched an near identical design concept back in 2012-ish (when 3D printing was in its infancy and I had an early Makerbot Replicator which wasn't really up to the task, plus my embedded knowledge was more rudimentary). Well done for getting so far! If I was going to tackle it today, I would probably program it in Mecrisp Stellaris Forth on a STM32F411, perhaps using a overclocked MIDI scheme or I2C. Forth is ideal for this sort of project - fast real time incremental compiling and testing with instant debugging feedback (unlike C), plus it is an order of magnitude faster than Micro Python.

@nicknack125 3 месяца назад

This is awesome and absolutely hilarious since I've been developing my own modular macropad line based on seeing the creativity console - all the steps you went through are legitimately all the steps I went through as well, even down to chucking an extra interrupt pin. I didn't have the thought to make custom pogo connectors though, that was a super clever design. Nice work! Also to add onto your part at 18:00 - my approach uses a single I2C controller device with some extra logic that auto-assigns I2C addresses after going through a discovery/scan process, which involves the peripheral device responding with its unique chip ID and a module type identifier. All keypresses or actions are buffered and then cleared on an I2C read, but latency issues like you mentioned start to pop up when you get 8+ devices. Cranking up I2C speeds worked for a bit but I am currently redesigning since I started hitting I2C bus capacitance issues at higher speeds.

@salimbenbouz 3 месяца назад

haha! that's amazing. I'm glad i'm not the only one to think this way. I received a lot of suggestions that I might try and buffering the interactions is one of them. thanks for the taking the time!

@e74av 4 месяца назад

A great option for combining all of the modules would actually be to connect those as a USB bus. All modules would be independent, the number of modules would mean nothing and you would get rid of any protocol definition and programming.

@lanepemberton8886 3 месяца назад

Also one less pin in the connector

Great solution for the magnetic connectors. I think that extending the connectors out, farther proud of the main pcb on each module would give you the ability to thicken the walls on the modules. That way you can have stronger magnets. I have a design for push-to-click square, small oled display buttons and other similar modules as yours but I didn't like the magnetic pogo pin connectors available - now I think that can be solved. To implement some of my ideas, I was considering SPI instead of I2C between modules but was concerned about the interconnect connector voltages and amperage limitations that would accumulate quickly with each subsequent added module as you get further away from the main power source. I wonder if CAN + I2C might be a better strategy?

Brilliant project :-) To help with stability and the magnets disconnecting you could print a thin frame that clips around the entire assembly once the modules have been magnetically snapped into position. Different configurations would need different frame sizes but that can be done parametrically in F360, to make it easy to generate then print. I also like the idea of making a v2 that fits Gridfinity: then it could be combined with other Gridfinity modules.
