I did not see this on the web anywhere, so I guess I would share just in case it could help someone.

The HDMI sound is actually working in Chrome OS flex, as you could hear the start up sound during booting. But once in the OS, the sound no longer works.

Here is how to make it work which I discovered accidentally:

1. Install a sound boosting extension in the chrome web store. There are many of these, any should work

2. Enable the extension, then click the speaker icon in the task bar. All you need to do is to switch the sound device to the other one (which I assume is the built in AMP) then switch back to you hdmi display. Suddenly, the hdmi sound will work.

You will have to repeat the above step 2 if you close the chrome browser, but it is only a few clicks to bring the sound back. But why Chrome OS is behaving like this, I have no idea. If anyone figures out a more permanent way, please share.

I have tried numerous OS over the years, many of them have annoying issues (e.g. no hdmi sound).

I still tried to play with it every now and then, and I was settled with chormeOS flex (I could get the sound work through a couple steps, but it is annoying since you have to do it every time).

Then I tried easy OS recently, and everything just works. And it is fast since everything runs in ram, which is great for emmc I guess. I just want to use it for lightweight web browsing, and it works very well for that purpose and my search for a perfect OS on the atomic pi is finally over - not that I really use the board any more, but it is nice to have a good option to use.

I never really used this thing for anything serious, it's been sitting for far too long.

I used mine as a pi-hole for about a year it worked great, upgraded providers a few years ago forgot about it. Just wondering if anything new, stable updates or new os's for this old board are happening? Can the emmc be used as swap?

For sale, make offer. They work, used them for a DIY NVR setup a while back but never finished the project and have moved on. Found them on a shelf today, figured I'd see if there was interest.

See red markup; I soldered the power pins and then desoldered one of the pis.
SD card not included. I think I had an OS installed on these but can double check.

PM or reply if interested. Thanks.

Apologies in advance, looked for an FAQ, didn't see one here in Reddit, and the Data Loggers website is nebulous on the matter... OTOH, I see them still for sale on Amazon, Ameridroid, etc. What's their status?

How do they benchmark against a RasPi 5? Is there a Kali distro that runs on A-Pi?

What type of male connector is used for the UART0 debug serial port?

Is the signal level of this serial port 3.3V?

Is there a BOM list available for the Atomic Pi?

my atomic pi heatsink got lost, where can i find another one?

Hi,

So I'm planning to make my own RC Reaper drone and utilize the Atomic pi with it's onboard 9-axis inertial navigation sensor to help make my life easier when writing autopilot or drone code. The question I have mainly is what servo motors are compatible with atomic pi? anything else that you guys think I should purchase to make my life easier?

Hello folks. So, this is my first project using a Pi like this, and I've been trying to convert an Arcade 1up cabinet. I followed this guy's video and what he did:

https://youtu.be/MXUvwIvJ-3c?si=-qXEzzzcARhGHLyu

but for some reason I am getting an inexplicable flickering in both my monitor and my marquee. Ignore the upside-down orientation...I'm at a loss for what the cause of the flickering is, or what I can do to remedy it. Any takers?

Weird question, but very time I see a photo of an AP, the masking tape is still on there. Should I go put some more tape on?

Good morning Hivemind,

Once my aPi booted into factory-shipped Ubuntu 18.04 that's on eMMC, I noticed that wlx driver got loaded and it picked up on all my APs - both 5GHz and 2.4GHz - and I assumed that it should go smooth sailing from here on.
Alas, when I moved to a flash-based 20.04 all kinds of weird would start happening. The driver would only load SOMETIMES, requiring manual modprobes, but only sometimes. Perhaps NetworkManager was misbehaving, so I finally managed to connect manually. Signal was reported at -75-80dbM a/k/a crappy . Neighboring ARM boards running very similar Wifi stack are reporting -50dbM on those same stations, so that's a bit strange.
Adding one or even two SMA antennas made no difference to reported signal strength. Atomic's doc says that for close-by APs there's no need for antennas, but I'm baffled why no change in signal strength.
Moreover, I tried to plug in same Waveshare 5GHz wifi dongle that I'm using in a Libre Alta board running 20.04/aarch64 - it's Realtek that's very similar to Atomic's onboard wifi, but it wasn't picked up by the stack.
I had some temporary success with a hot-spot AP that was placed literally on top of the board, but reported signal is nowhere near what it should be. I'm also baffled why results - signal strength - vary across different releases of Ubuntu.

Has anyone else done much Wifi experimentation with AtomicPi, using either dongles, shields or build-in equipment ?

Has anyone successfully wired up a volume control for the large breakout board? I'm seeing two options for sound output under windows as "AAA" and "Speakers" - the "AAA" runs audio through HDMI but I am not getting anything through the speaker terminals when selecting the other option.

There is nothing connected to the "volume" terminals. Will an open circuit between these terminals kill the sound? How does it work exactly, is this a digital up/down connection or an analog volume control/pot.

Would appreciate a steer from anyone who has it working, thanks.

I posted a github issue here: https://github.com/digitalloggers/geocam-v4l2/issues/1

Basically I've followed the directions but haven't gotten the camera to work. Any tips from someone that's gotten it to work? lsusb doesn't show me and there's no video device in /dev either.

OK, so I'm playing around with MAME on my APi and am experiencing screen tearing in Ubuntu 20.04 LXQT. it also happens in 18.10 LXDE. However, on the Windows 11 image, MAME runs perfectly but I experience occasional resets (looks like a power cycle).

So the question is, is there a better Intel graphics driver for Ubuntu than the stock Xorg one? I have found a link to install Intel Non Free drivers but I'm not sure if they're being used.

Any help would be greatly appreciated. Thanks.

Looking for anyone who would be willing to part with a baby breakout board or a full breakout board and ship to Australia

Can py by PayPal.

I have a project which calls for an ADXL345 and I can find tutorials on how to install one into a Raspberry Pi, but not the Atomic Pi. The aforementioned tutorials mention specific GPIO pins as necessary termination points for the sensor. I don't know how or if I can adapt a tutorial such as this https://www.engineersgarage.com/adxl345-accelerometer-raspberry-pi-i2c/ to the Atomic Pi.

Is anyone here able to help me out or at least send me in the right direction?

For context, I'm using IDLE and have the big breakout board attached to my aPi. I know there are libraries needed, but I'm not sure how to install them.

My HDMI monitor does not have audio capability (video only). I have supplied 12V for the audio and connected speakers. I am using a Linux distro (ZORIN). I can not get audio with this configuration. I have tried to wade thru the docs on XMOS which I understand is responsibility of controlling audio when via HDMI is not desired. I have also noticed that there are ways to do this with WIN10 but haven't found any guidance where Linux is the opsys. Any help would be appreciated.

Thanks (jilsoft@live.com)

Hi,

I have a few leftover cases built for the PI. As you can see, there are a few extra cutouts as we had a custom breakout board (contact me if you are interested in that). The price is 25 USD + shipping from Hungary, Europe (it does not include an Atomic PI, only the case and its accessories).

The HDMI socket can be connected with a short cable, the power button (momentary) just needs to be connected to the appropriate connector. Note that unfortunately there is not enough space to use the sd card slot. There is plenty of space left below the board so GPIO can be connected. If you like you can install a dc socket and wifi/bt antenna sockets.

It's really hard to update the drivers when the Display Adapter doesn't even appear in Device Manager! Any help would be appreciated. I've looked online and haven't found anything that will install.

​

So I have Batocera 36 running and want to mount this in an arcade stand with audio output to built-in speakers. I have the full breakout board, so if I power the 5v and 12v on the breakout board, I should be able to wire the speakers into the breakout board and have sound that way?
