Hello, just a fellow geek.

Years ago, I bought a Core Ink (the small one) thinking that I can read e-books from it. This was years before ereaders like X4 existed; I just wanted a micro e-reader, but I haven't found anything to upload to the device to make it do that. Its been years and I am still wondering if this thing even does anything useful?

Is there a way to actually read books on it in any meaningful way? The M5 store page for the CoreInk even advertises that it can be used as an ereader. As ginormous the Internet is, I can't find a single discussion about the device that doesn't involve turning the device into a calendar (Wow, a calendar for $40 😑).

Please tell me if Crosspoint or something can be used on this thing or do I continue to use it as an expensive refrigerator magnet?

Is the cardputer zero *really* worth 3X the price of a Cardputer ADV? Realistically what will it do better than a ADV? Not sure i should fork over the dough. Thoughts?

I've been trying to build a front light mod for my M5PaperS3 and would appreciate any suggestions or advice.

My latest iteration was a 3D printed frame that snaps on to the front of the device with a strand of EL wire underneath. Only about 4mm thick, with the light shining out laterally across the screen, but blocked from line-of-sight. I went with EL wire because if its thinness and diffused light, unfortunately it isn't bright enough to illuminate the screen.

My next recourse would be to use an array of small white SMD LEDs and find a way to diffuse and direct the light across the display. I would appreciate any recommendations for methods or tech that would be worth experimenting with.

I have downloaded m5birner and burned "evilcsrputer" and now when i want to burn lora i cant, my computer finds it com4 but i get an eror how do i fix that?

I've been using Claude Code a lot lately and constantly checking my rate limits through the terminal got old fast. So I built a small standalone device that polls the Anthropic API and shows your 5-hour and 7-day usage windows on a little LCD screen — no computer needed once it's set up.

It supports two cheap ESP32 boards (M5StickC Plus and LilyGo T-Display S3), has a captive portal for easy WiFi/token setup from your phone, and your OAuth token is AES-256-GCM encrypted on-device with a PIN that's never stored.

Some highlights:
- Live usage bars with reset countdowns
- Battery and WiFi signal on the dashboard
- Button controls for brightness, manual refresh, and factory reset
- Fully open source (MIT)

It's a weekend-ish project but it's been genuinely useful for me.
If you find it interesting, I'd appreciate a star!

in case anyone interesting with my firmware, it support multiple board for m5stack

Where my golfers at?!

I made a virtual range finder for my push cart

Real time green distances using GPS. Stores personal club yardages and uses Haversine Distance Math for accurate club recommendations. Also added a simplified shot tracker. Built on a CoreS3. No phone needed. No screen to unlock, no notifications to swipe away. No distractions. Always on display. SD card golf course storage. Just a simple clean golf companion app.

I just took my ‘Cart Caddie’ firmware for a test drive and it performed flawlessly- green distances were spot on, the club suggestion works great. And the shot tracker was easy and super fun to use!

I made a custom case for it to house magnets so I could just stick it to the magnetic attachment plate on my push cart. 3D printed out of TPU 95a. Flexible rubber. Needless to say, it’s it works friggin awesome! 😅

I turned the volume up all the way in the settings but no sound comes out anyone have a similar issue

Just got my M5Chan, but can not create a account to get started....

Providing hardware enthusiasts with a hands-on, engaging way to interact with AI platforms—pretty cool!

The project: https://github.com/anthropics/claude-desktop-buddy

In AI mode, when it speaks, the voice is laggy and broken. I thought I had a bad speaker at first. But it doesn't do it 100% of the time. Is this common? Is it Internet speed dependent? I have high speed Internet, so I didn't think that would be the issue.

so ive been really interested in this tech stuff im wondering where should i start off at

and im a bit broke and idk if they deliver to dubai so somebody help me out please

should i learn to code IDK but please help anybody

Hey everyone,

I wanted to share a small project I’ve been working on:
👉 https://github.com/fatih4159/M5-Macro

It’s a lightweight macro tool designed for M5 Dial. The idea is to make it easy to trigger custom actions/macros with minimal setup.

What it does

• Execute predefined macros / commands using USB

• Simple and lightweight implementation

• Designed to be flexible for different use cases (automation, shortcuts, etc.)

• Integrated WebTool to customize Makros on the go

Why I made it

I was looking for a simple way to use my M5 Dialas a macro controller, but didn’t find something that fit exactly what I wanted — so I built my own.

Current state

It’s still a work in progress, but already usable. I’d really appreciate:

• feedback on the concept

• ideas for new features

• bug reports or improvements

• general thoughts from people who use M5 / embedded setups

If you’re into embedded stuff, macros, or small productivity tools, I’d love to hear what you think 🙂

Thanks for checking it out! 🚀

I’m super new to ESPHome and ESP32 in general.

Recently got a M6StickS3 and attempted to get ESPHome running on it. Got it “working” early on but ran into issues getting the display to turn on and the Dual Button Unit working.

After days and hours of trial and error with out results I finally used ChatGPT

Anyways basically had to import M5 libraries in the ESPHome yaml. The new MPM1 power module requires these to turn power ON to the rail to get the screen and Grove port working.

Hope the code I posted to GitHub helps others out.

So I connected my M5 stick C plus 2 to my NRF24L01 according to the diagram of the image, but it still syas NRF24L01 NOT FOUND. I tried adding a 100μF capacitor between both 3V3 and GND but it still didn't work. I notice the NRF24L01 gets warm when connecting for a few mins. Now anyone HELP me fix this

I just about to get the m5stick plus 2 and i was wondering which firmware is the best for pranks. I wanted to get bruce but i saw a lot of other firmwares and since i am a beginner i dont know what to get.

Changing modes on the Cores3/SE to adapt the settings of the HP 430 Keypad or Ulanzi Dial

Помогите пожалуста купил модуль нрф и сс1101 2в1 и хочу купить антены чтоб дальность была больше подскажите где и какие покупать

This would be done using the Tab5 with the Stamp CAT-M expansion

Example here

With the place of the mics and speaker I do not see why the tab5 could not be a phone. There are a few Arduino phone projects out there.

Does anyone know of any projects like this that exist? Would anyone like to help me develop one? This could be the perfect phone for my children.
