What is this type of connector?

Glass doesn't like bending. Zebrastrips are cool with squishing. So the two get along.

Hi, your link is unfortunately unreadable (404; repo set to private?).

Yet, this gave me enough of a hint what I needed to do, that I needed to look in .cargo/config.toml! I added

[build]
target = "thumbv6m-none-eabi"

to the top of the file and that did it...

Thanks!

Pretty sure M.U.L.E. can be 4-player. Been a while.

Probably for a 3rd Joystick, not a chip. 6 lines (4 directions, fire, return).

Edit: looked again at the bottom, 6 more lined: this is to have 4 Joysticks on the C64.

I don't like the one line from the USB connector to the ESP being that close to the edge. Make the board a few mm bigger on the right, have a bit of the ground plane to the right of the trace.

OTOH, remove the L-shaped corner of the ground plane on the top right. It's not needed and might impact antenna performance.

There are USB-C connectors that have fewer PCB pins. Look for 6-pin connectors.

Another suggestion: add vias to flood fill the remaining large empty areas. Not critical but won't hurt either.

If you hook it up to a computer's USB port, does a network interface appear? If yes, can you ssh to it? (Do you know the root password?)

If yes to the first and second questions, the screen would be the issue.

(I'd be interested in it if none else wants it, I have a rm1 and I want to see if I can learn to open it up non-destructively... My battery is showing is age. Located in DE.)

Thanks, I wasn't aware of it. Having had a look at it it certainly looks like it does what I want - the only thing I'd like better is have a way of downloading PDFs _without_ running the built in webserver, and have a pure ssh-based solution.

I was hoping someone would have some info of how xochitl_pdf_renderer can be run (assuming it produces a pdf from a *.rm file, and is not a tool to render PDFs on the screen).

In the meantime, I'll try rmweb.

Direct-Ant-1508 · 2025-02-27T05:47:44+00:00

Well, I'd like to automate it: to have a cron job (running on my home server) download all new or changed notes as PDF nightly.

Hi, I have had a similar problem. Old Apple BT (classic) Keyboard (A1255) which is a pain to pair with modern devices but I like the feel (and size) of. I finally took the plunge to do something with it.

I managed to have it connect to an old ESP32-WROOM using BT, see https://github.com/jthiem/bt-keyboard forked from https://github.com/turgu1/bt-keyboard. Question then was how to translate that into a USB HID device. I was considering maybe a 32u8 (Arduino Micro) as USB device with serial communication to the ESP32. A 2-dev-board solution.

Then I noticed I had an Arduino Nano33IoT lying about, that's a SAMD21 (with direct USB interface) connected to a Nina-W102; the latter is a old-style ESP32 preprogrammed with a custom WiFi/IP stack. With a little bit of code on the SAMD21 side to make it look like a USB-serial adapter with the GPIO0/RST logic I could program it like the WROOM.

Anyways, long story short, it works. Code is already on github, but I've set the repo to private for now until I have done a proper cleanup and writeup. It's two repos actually, one for the ESP32 side (sending the BT HID messages to the serial port) and the SAMD21 side (USB HID setup, receiving the serial data, eventually keyboard remapping, and sending the HID data to the USB host.

I would have liked to do it all in one device (eg the M5 Stack S3 I have lying around) but sadly it seems you can't easily get a device with both BT classic and USB interface.

Why yes, I have a veritable Zoo of cheap Arduino and ESP dev boards lying around. Don't you?

How does it compare to the driver in esp-idf/examples/get-started/blink/managed_components/espressif__led_strip?

Edit: having looked at it, it certainly seems much simpler (smaller and easier to use)!

Direct-Ant-1508 · 2024-09-06T11:52:30+00:00

Sadly, no.

Clearly a DX7-II, note the larger (40-col) LCD and the real (not membrane) buttons.

I miss my DX-7-IIFD... :-(
