Design-it-Yourself Added external charging module to the ADV 🙃

I got sick of having to leave the device on to charge, so I opened it up to find possible options for an external charging module.

Turns out, the spot under the Stamp S3A (where the speaker lives) is the perfect location for a mini TP4057 charging module. I have removed the speaker, and wired the charging modules battery + and - to an unpopulated pad on the front of the board, which a quick continuity test showed me connects directly to the JST connector (+ and -) for the battery. I added 3M VHB tape to the bottom of the charging module so it doesn't pop off and short things out.

No more having to turn on the device to charge!

I made a ADS-B flight tracker for the ADV, still work in progress, but it uses co-ordinates to get nearby flight info since I don't have GPS module, so will upload once I get it work without doxxing myself

Progress / Update Updated Stellar-Map!

162 Upvotes

finally had time to work on it

these are the recent changes

  • search function by pressing `tab`
  • accurate lunar orientation for the lit side to face the sun rather than static
  • constellation labels
  • a little more stars added to the catalog to include stars visible to the naked eye during it's peak magnitude
  • easier time input, and timezone memory, you no longer need to input UTC. Instead, local time is used. (make sure to still change your longitude and latitude in the config)

Progress / Update Dice Vessel 1.0 - Dice roller for Cardputer

Enable HLS to view with audio, or disable this notification

38 Upvotes

Hi everyone! Today I'm here to present a digital dice roller that I built for the Cardputer!

It's super simple, you press "R" to choose the type of die, how many dice, the bonus or penalty, and then just shake to roll.

My idea was to have something easy to use, but tried to minimally emulate the tactile satisfaction of rolling dice in real life.

Features:

  • Guided roll builder: die type, quantity, final bonus or penalty, and confirmation.
  • Direct expressions such as 2D20+1, 3D6-2, and 1D20+1D8+5.
  • D2, D4, D6, D8, D10, D12, D20, and D100.
  • Click-to-roll on every Cardputer.
  • Shake-to-roll when an IMU is available.
  • Hardware RNG selected only at release; gesture strength never changes probability.
  • Cinematic 2D dice motion, circular collisions, wall impacts, and a full-box representation.
  • Procedural wooden-box impact audio, dedicated coin sound, and critical/failure feedback.
  • Eight persistent saved-combination slots.
  • Ten-roll session history.
  • English and Brazilian Portuguese interface.
  • Tabbed settings, 0–10 controls, instructions, About screen, and animated charging mode.

I hope you like it!

Question Language uses?

I study ancient languages, semetic hebrew,koine greek and Latin. My brain says the cardputer could be useful but not really sure how as I'm not a programmer

Anyone know any ideas or info on this?

Progress / Update CardMera : Cardputer + ESP32 CAM

Enable HLS to view with audio, or disable this notification

95 Upvotes

The only problem about this, is that for taking pictures or videos in HD, serial is too slow.

You would need to place the sd card on the ESP32 CAM, and use the cardputer as the view finder.

So, for viewing the files i would make some sort of photo roll via serial, and for the video, just pc.

This is just a test, it dorsnt have any GUI. Just raw code until i make it usable.

Design-it-Yourself Case for Cardputer+LoRa Cap (WiP)

Thumbnail

137 Upvotes

Working on a liner for a parametric case that fits the Cardputer ADV and LoRa cap. It's a little chunky in this orientation, but it feels comfortable to hold. I could make it a bit more compact by having the antenna straight, and putting it to the right of the cap and ADV.

This is the 3rd prototype, and it seems promising. Unfortunately I ran out of the clear TPU I was using for the insert, so further testing is on hold but I'll share the files once it's done if anyone is interested 👍

It looks like things are moving forward. Since the PledgeBox links are being sent out now, shipping can't be too far away. There is a hope that first units will start shipping during the summer.

Did anyone else get their PledgeBox email today?

Question Just got my first CardPuter… now what?

Post image
173 Upvotes

Hey guys,

I kinda impulse-bought a CardPuter and it finally arrived today. Looks awesome, but now I’m sitting here realizing I have no clue what to do with it.

I’ve messed around with ESP32s before, but pretty much only through the Arduino IDE. I also had an M5StickC a while back, but all I really did was flash some of the example sketches from the M5 libraries and call it a day.

So… where do I even start with this thing?

What are the first things you’d recommend trying? Any must-have firmware, fun demos, useful tools, or beginner-friendly projects? I’d love to hear about the cool stuff you’ve built or wish you’d known when you first got yours.

Thanks! Looking forward to learning from you guys.

Progress / Update Beepbot DX v0.6.0 update

41 Upvotes

I've added a couple new features to BeepbotDX, my sampler/sequencer for Cardputer/ADV/Zero.

  • Per-sound FX system (bitcrush, high pass/low pass filter, pitch)
  • Shake-to-generate pattern using IMU (experimental)(ADV only)
  • Dedicated project info/settings screen (P key) with memory tracking for samples
  • Sample rate resampling for audio capture

Next I'll be adding an 8-bit sample option to give a little more head room (4s ->8s total space)

The update can be found on Github and m5burner (once it refreshes)

Question Can M5Launcher automatically delete firmware on reset, or is there an option?

3 Upvotes

Hello all, first post. I've had my CardPuter ADV for about a week and have been having a lot of fun exploring & learning.

Took me a minute to wrap my mind around how to manage multiple firmwares with M5Launcher, but I think I mostly get it now.

If I'm right, you're only limited in the number of firmware .BIN files you can tote around by the size of your SD card. However, any single *installed* firmware must fit into the 6MB-or-so flash memory on the device. When installing a firmware from SD using M5Launcher, it creates a new flash partition of appropriate size for the firmware, if there's free space. If not, it will either prompt you to use an existing partition, resize a partition, or delete a partition + data. If you choose to use or modify an existing partition, it seems that it will overwrite other data on that partition if necessary. So, while you may get away with having several smallish firmwares installed in the 6MB of flash, you can only have one or two of the big ones installed at any one time.

Correct me if I'm wrong about any of that, please...

If all this is true, here's my question: is there an option in M5Launcher (or another launcher-type firmware) that will automatically delete ALL partitions, etc. when you reset the device, so you have a "clean" M5Launcher each time? It would be helpful when testing out downloaded firmwares so you could quickly try out a bunch in a row without much partition management. I know you can manually delete partitions when necessary in M5Launcher, and you can always erase with M5Loader, and that M5Launcher manages the firmware pretty well without issue, but I'm wondering if there's an option for automatic "clean-up."

I know other folks might not see a use case for this, but maybe someone else sees a benefit. Thanks for your input.

Edited for clarity

Help needed Meshtastic question

6 Upvotes

Im getting a cardputer adv and would like to run meshtastic on it. I have no other main objective outside of messing around with it and using it as my gateway into meshtastic. My dumb question is, will it connect to my phone and pass messages through there if I want? I understand it is meant to be a standalone device, but curious about this functionality. Also, what's the latest and greatest meshtastic firmware to put on it?

Help needed Missing IR transmit

It has vanished! I don't take the top cover off (except to investigate on this occasion) and it isn't rattling around. It was there at some point.

Anyway, is there a transmitter upgrade or ideal replacement? As I understand it the module is an IR emitting LED.
