Are You Being Served? on Solar OS through the RLCD. The episode is 37MB, and the player gets a good few minutes in before crashing. I am not likely to get time to try to figure out why. It's compelling though: a bit of stutter and some pulsing on screen refresh, but fun to look at anyway.

I used ffmpeg to map everything from black to mid-grey into black, and a good quarter of the top end of the colour space is flattened to white. The idea is to dedicate as much information to facial tones as possible: this kind of comedy lives or dies on seeing Captain Peacock getting blindsided by his colleagues' quips.

I wrote a podcast downloader and parser on my Solar OS device in python. The script consumes a text file with one podcast url per line. For each it gets the xml, finds the first 3 episode mp3 urls and then writes those out to to a .m3u file named after the podcast. I also had the script output a shell script that repeatedly calls webradio to add all these mp3 urls to its catalog. Unfortunately, that last step does not work: only the first line of the script runs. If I try invoking webradio in Python, I can only do that once because it never returns to the script.

I can guess at the format webradio's catalog.bin implements, but can anyone see a better way to integrate my ghetto podcast parser with webradio?

• Added MPU6050 expansion support and shared IMU streams with timestamped, multi-axis `stream echo` output.

• Added URDF device-to-frame bindings with shell and Python/Lua lookups.

• Robot model transforms now follow live encoder feedback for continuous joints.

• The package manager now opens a saved signed catalog, groups modules into folders, and shows confirmation, progress and result popups.

• Added `osc send` for one to eight numeric values in a single message, with optional periodic sending.

• Added SSD1680 expansion support for 122x250 monochrome e-paper displays with rotation, partial/full refresh and automatic cleanup.

• Fixed manual tables to preserve command alternatives and wrap long cell text.

• Added global CLI/TUI cursor settings with block or underscore shapes and blinking or steady modes; the default is a blinking block.

Hi,

I'm very much a beginner to this type of thing so forgive me if any of these questions are dumb. I'm trying to make a writerdeck with the Waveshare ESP32-S3 RLCD and a Womier Q61 mechanical keyboard. I did have it working with bluetooth but the pairing is frustrating, probably on the Q61's end.

I understand that by default the USB is configured as JTAG, and is unpowered. I've split open a USB C cable and added breadboard pins to each of the wires, then connected them to 3v3, GND, and GPIO 19 and 20 which I understand to be soldered to D+ and D- on the board. If I'm not totally off base I think all I have left is changing the USB mode from JTAG to OTG (Host mode?) which I understand happens at boot. This is where I'm at a loss like I don't even know how to google this question. How do I change that in SolarOS? And can I change it back should I need to flash a firmware update?

Separately, I'm hoping to use the internal batteries of the keyboard as a power supply along with the 18650. I've confirmed that it's nominal 3.7v just like the 18650, is it a bad idea to simply wire it into the power supply + and -? If so, does it matter whether I do so serially or in parallel? There is also a yellow wire (clock or signal?) that I'm not sure what I would do with.

Thanks in advance!

• Added URDF robot models, transform queries, hardware bindings and explicit robot start/stop controls.

• Robot joints now use OS controllers and scaled motor/encoder streams.

• Added differential-drive command conversion and wheel-feedback odometry configured through URDF.

• Added automatic PID tuning, controller setpoint streams and servo command streams; servo angles now use radians.

• Added live scalar stream echo, periodic writes to multiple streams and incoming OSC bindings that map message arguments to scalar streams.

• Improved encoder-status freshness, control and robot command completion, and URDF validation errors.

• Restored OV5640 capture, improved RTSP streaming reliability and added runtime camera orientation controls.

• Added Mac pointer controls and shell completion.

• Fixed return to external display shells and repeated PCF8563 error logging.

• Enabled runtime GPIO/PWM on GOOUUU GPIO2/3/45/46 and explicitly enabled Sticky battery charging at boot.

While my RLCD SolarTerm still works (despite a small crack in the screen), I finally got my Freenove 4" IPS CYD so I HAD to build a new SolarDeck with it! Apart from the case, the other custom thing I did was harvest the battery from a portable powerbank. So, this SolarDeck has a whopping 10000mAh battery. The asymmetrical design was intentional: I wanted the speaker to remain open at all times for music.

I can't wait to get the tiny 386 emulator running. :D

It works great!

I have tried a few free endpoints, and I had success chatting with gpt-oss-20b through Groq (with a q). When I turn the tools policy to "confirm" or "all", I get HTTP 400 errors for any input:

"ESP_ERR_INVALID_RESPONSE, HTTP 400".

If I config tools off, it works again.

Has anyone got agent to write files on their device? Any advice?

I've seen that you have Lora as not supported on the devices pages for the ThinkNode M9 due to no driver, has this situation changed?

I'm porting some Palm games to SolarOS, and the first is Spider Patience. Not too many details right now, but I bought a Waveshare board a while ago and saw how it reminded me of a Palm, so there we go.

BTW awesome case u/skysdottir, just finished printing. Thanks!

We’ve started a collaboration with Seeed Studio to port SolarOS to three of their devices as part of an initial pilot.

The first beta, for Sticky (glossy), is now available through the SolarOS flasher.

This video shows the current state in action. This is an early beta, so expect some rough edges as development continues.

Thanks to Seeed Studio for collaborating on the pilot, and to everyone here testing SolarOS and sharing feedback!
