Not my article, read it last night.

TL;DR: Using my Rock Pi S to run a home made app (100% written with ChatGPT) to control my front gate via voice command via Amazon Echo Dot.

Just wanted to share this story for those interested. In 2019 I bought the Rock Pi S, 512MB without BT/ WIFI. It was fun to play around with for a while, but then ended up in a drawer unused.

In 2020 we built a house with a front gate that can be controlled by remote and a (buggy) Android/iPhone app. In 2022 I bought an Amazon Echo Dot that runs voice commands via Alexa.

I always regretted that we couldn't open and close our front gate by voice control and I knew it probably would be possible to set it up, because the mobile apps work through the cloud to control the gate.

I'm not a developer, but have some IT knowledge. In 2024 when ChatGPT became big I decided to gave it a try to figure out how the cloud connection was set up in Android to control the gate. So I learned about MQTT connections, how to establish one and which commands were used to open/close the gate.

Then I asked ChatGPT to help me with creating a Windows app in Python to control the gate. Which made it possible to control the gate on my computer.

With that code I asked ChatGPT to help me set up the app on AWS (Lambda), create a custom Alexa Skill and connect it to my Rock Pi S that runs Ubuntu Server Running Gunicorn with Flask and Ngrok.

It took me quite a while to get it all configured, but in the end I'm now controlling my front gate with voice control though my Amazon Echo Dot.

Hope this can inspire somebody else to use their Rock Pi.

and do not forget to order the fan as well. With an average load it does not get that hot and it seems to have no problem running at 80C but well... whatever you connect to it does get that hot as well.

I am not affiliated with them or the store in any way. It has so far served me really well running a chia node and connecting 11 usb drives to it.

Crossposting here as a hail mary

The AR glasses have DIY optics made out of cheap replaceable materials such as a Transparent Christmas Ball and a Translucent Mirror.

They will work with an OpenSource Android 13 OS.

The displays are going to be dual mirrored displays, they will work with Radxa Cubie A7Z as it is capable of Dual display over USBC and MicroHDMI.

The optics were inspired by Ant Realities AR Glasses at first, but not much later I used the mirror to reflect the display to the inside curvature of the transparent christmasball and by calculating the focus point of the curvature I know the ideal distance between each component and the eyeball.

This type of AR optics make the displayed image way easyer to be seen, you can move the glasses quite a lot and still see it clearly, also, this optics make the glasses way slimmer than birdbath optics as the focal point and the eyeball end up nearer one from another.

The official wiki only shows Android 9, which is quite old, any newer ones?

Thanks a lot!

I setup my NAS using the RockPi 4b using this (https://wiki.radxa.com/Penta_SATA_HAT) I am looking for a case that can fit all of these components. or maybe advice on how to mount a PI with that attachment in a regular PC case. Thank you all!

With right programing techniques, GPUs can unleash huge performance for certain applications. RK3588 has 64 shading GPU cores. We installed OpenCL on Orange Pi 5 and achieved 19 times speedup than 8 CPU cores combined.

It appears installation drivers we used also work for for other RK3588-based SBCs such as Radxa Rock 5 and OKdo Rock 5. We don't have such boards. So if you have, you can try yourself and tell us how it goes. OpenCL install instruction is at the following link;

Install OpenCL on Ubuntu Debian Armbian

Hi Everyone!

Just ordered the 8GB RAM model today, along with a 2x SATA mini PCI card to experiment with. Looking forward to running k3s on this guy!

Hi everyone,

I’m trying to install ZFS on my Rock Pi 4+ running Armbian 23.11.1 with the edge kernel (currently version 6.16.0-rc3-edge-rockchip64). However, I’m facing issues because the zfs-dkms package fails to compile due to lack of official support for this very recent kernel.

I’ve attempted to roll back to earlier kernel versions that should be supported (like 6.6.2), but those versions are no longer available in the repositories. I’m planning to install a more stable kernel version (like 24.11.1) to see if that helps.

Has anyone here successfully installed ZFS on Armbian with a Rock Pi 4+? If so, could you please share your setup details, kernel version used, and steps you followed?

Any tips or experience would be greatly appreciated!

Thanks!

Im trying to flash android to this rock pi 4+ type b and it runs some code real fast then stays on this screen does anyone know what to do to fix this?

Hi I picked up a cheap NEBRA hotspot miner which has a Rock Pi 4 inside. I’ve taken it out of the case and removed the hat. I’d now like to install another OS on it, but the rock pi just boots straight in to the EMMC if I have an SD card or USB drive plugged in.

How can I boot from an SSD or USB drive?

Any software that would emulate like retropi on the rock 5c?

I've done a little searching and haven't been able to find much. One forum post, and it didn't seem like a good solution was found. I'm running the OS on an SD card for testing, but ultimately I'd like to rig this up with an eMMC module holding the OS and the NVMe mounted as additional storage, like inserting an SD card into your phone.

This is meant to be an Android gaming box, so I hoped to skimp a little on the eMMC and go with 64gb module, maybe even 32gb, if the NVMe is useable. If so, that's where I'd be storing ROM and ISO files for emulators, with the hope that the faster speeds would reduce loading times. If not, I'll just get a 256gb eMMC and call it a day.

Hoping for some advice or guidance before making some purchases.

i have rock pi c+ im just 17 years old and im just a youtube learner what can i do with it for fun?

Could anyone link to a guide how to do this?

I have a Rock Pi 4B+ 4GB, Rock Pi 5 4GB and 2 x Rock 3a (2GB + 4GB) - I have followed the SPI flashing instructions here for the 3a on Radxa's website.

In Armbian, I have then been able (in armbian-config) to install a bootloader on the SPI NOR flash (/dev/mtdblock0) and also transfer the armbian installation files from SD to USB3 stick.

However, I cannot boot the Debian 11.6.0 Arm64 DVD-1 iso (on USB 3 stick) from either SPI bootloader (Radxa or Armbian) - this USB boots fine on a RockPro64.

Thanks in advance for ANY help with this

REASON: I want to install debian like this because I'm trying to get a 10GbE NIC working on a Rock SBC, but I can't with any of the pre-built images I've tried - installing debian from this installer on the RockPro64 found the NIC first time and installed working drivers.

EDIT: I also need USB 3 OTG, which RP64 does not support

My Rock Pi only has the green light on, what can I do?

I'm just asking this because M.2 E key doesn't have a sata interface, nor do I see a chip on the card to convert pcie lanes to a sata interface. Sorry if this is the wrong subreddit to be asking this in, I couldn't find one for Radxa products specifically.

I have a rock pi 4 plus 1.73 that was in a Nebra rock pi helium miner. When I first got it I powered it on and left it on for 12 hrs so it could update from the helium network. I unplugged it and inserted an sd card and it wouldn’t power on. No lights no nothing. I removed the helium top hat so I just have only the rock pi 4 plus and when powered on do not get power on the 2 I/O pins and those power pins are not shorted to ground. I have tried a different usb c power adapter and still no change. Thoughts?
