Project mention: Ask HN: Nobody interested an open hardware iPod Nano? | news.ycombinator.com | 2024-02-29

So here is the thing: The iPod Nano 7g is from 2012. I've seen many people designing custom PCBs and releasing Kickstarter projects for custom audio players[5] or game handhelds[6]. I know Rockbox (which is great, but its lacks support for Wifi and Bluetooth AFAIK and just does not compete with the UX of iPod's audio book features in my opinion) and iPod Linux. 10 years ago someone even reverse engineered the iPod Nano 6g display[3].

Although I'm not skilled enough in PCB-Design, after some research I found the Lilygo T-Display S3 Pro[4] based on ESP32 S3, which would be the size, but lacks audio and OS. There is also the Mango PI CyberPad[7], which looked interesting, but maybe is already too clunky.

Programming wise, LVGL[8] may be a good framework to develop a modern and efficient UI - at least it looks promising.

So, why is nobody interested in recreating an iPod nano like device? It should be doable with modern tech, but Phones have completely taken over the marked...

Project mention: Ask HN: Anyone Waiting on BT Auracast? | news.ycombinator.com | 2023-12-16

Hey folks. Anyone out there waiting for BT Auracast? It was announced June 2022, and immediately struck me as must have.

I lost my earbuds, but it seems ridiculous to get a replacement without Auracast, seems like surely if I'm going to make a decent sized purchase like that it needs to support group playing. I want to tune into the radios of other people on the metro or on the bus, want to be able to watch a movie on the plane with someone.

Auracast was announced in June 2022. Anyone else out there struggling with expectations here? I'm really hoping the product announcement season that's right around the corner had a good number of Auracast announcements.

Side note, a ton of it is over my head but it's been so so fun tuning in every once and again to see how Zephyr's Bluetooth Audio work is going. Just wild now much has gone into this! https://github.com/zephyrproject-rtos/zephyr/commits/main/subsys/bluetooth/audio

Project mention: Release v0.5.9.10 · embox/embox | /r/embedded | 2023-07-01

Embox is a configurable RTOS designed for resource constrained and embedded systems. Embox main idea is using Linux software without Linux. (https://embox.github.io/ ) If you want use complex Linux Software and Linux is huge for your goals. Embox is the best idea, as I think. For example Embox is the only RTOS that allows to use OpenCV on Cortex-m MCUs https://www.embedded.com/benchmarking-opencv-on-stm32-mcus/
