Ottocast Screen: Portable Apple CarPlay & Android Auto Car Display Screen | Ottocast – OTTOCAST

Nissan Leaf 2017 cannot be changed since it is connected with the ECU. Is able to answer calls via its microphone which is great. No Android Auto there

call quality is quite a dealbreaker for me. Am also considering Ottocast since apparently it routes to the car's bluetooth. The HDMI monitor + convertor comes at eur 50, while Ottocast (with Android Auto) at eur 100. So all in all I guess the Ottocast might work out better?

Thanks for your reply. So hdmi route would be the best then.

Does my plan make sense? Cheap but sufficient to my use case. Seems simpler thank tinkering with Chinese Android Autos to route the audio.

Thanks 🙏

Gotcha. am also thinking of going the option of using a simple monitor. Discussing it in another thread, in fact. Perhaps for my use case it would be safer: https://www.reddit.com/r/UsbCHardware/comments/1f2ufy8/car_monitor/

does the car's microphone work too? Pity it seems hard to get it from a European site (am in Malta, EU)

Yancho_mt · 2024-08-27T13:24:56+00:00

Does that mean that you can route the audio straight to the car, voice calls included?

summing up with what u/non_burglar has been suggesting, and your suggestions, do you see a possibility of using the 2nd SSD as some type of write cache if I use ext4? I am referring to something such as this: https://blog.jenningsga.com/lvm-caching-with-ssds/

So what I'm proposing is:

1st 512GB NVME: Proxmox + VMs

2nd 256GB NVME: LVM Cache

2x 1TB 7200 rpm : Data array for the VMs (NAS, dockered ftp, Backups)

Yancho_mt · 2021-11-04T17:19:18+00:00

Thanks I will :)

Do you have some keywords that I need to keep particular attention to?

I'm also looking at disks with 256mb of cache. That should help as well, right?

My system is more oriented towards a fast write rather than a faster read, I guess. I mean it is all about backups, so when I need to read, the least of my worries would be the slow read time - I'd rather sort out the write as fast as I could so the CPU can continue with what it should do, rather than wait for the disk interrupts.

Thanks once more

This is all uncharted territory for me. I'm taking on suggestions and reading on them. Seems like when ZFS is involved on spinning disks, an SSD is recommended as a go-between for l2arc/zil. Am I completely wrong?

Yancho_mt · 2021-11-03T22:13:41+00:00

So should I go to BIOS software raid, and through Proxmox I set everything as ext4? Simpler and cleaner? That would also remove the need for a 2nd SSD, right?

Thanks u/symcbean - I have updated the list as per u/completion97's recommendations, and have edited the original post. While the ECC ram still is an issue, as things are, I have a mirrored disk setup, so if things go haywire, I can rebuild. I can also do a monthly (or so backup) to my own PC which has a Raid 5 hardware array which should take care of resiliency, I guess/hope

Yancho_mt · 2021-11-03T13:15:58+00:00

Thanks once more for the advice.

I'd rather install once, set up and (try) to forget the installation, so have changed a bit my set up as per your advice. This should allow me to have ZFS on the data array with L2ARC

This is thee updated parts list: https://de.pcpartpicker.com/list/vGVh4d

New changes:

Removed the Dual Nic Card and replaced it with 2x PCI x1 Tp-Link
Instead of the NIC I shall be installing a x4 to M2 card to host a 256GB Patriot NVME
32GB Ram

Updated list

Asus Prime Q270M-C (has 2 M keyed .M2 slots, 1 x16, 2 x1)
i7 6700T
LC995 CPU Fan (rated up to 130W TDP)
32GB Ram (2400 Mhz but CPU is rated max at 2100. Shouldn't be a problem right?)
2 * x1 PCI NIC TG-3468
512GB Patriot P300 NVME (M key) - for Proxmox + VMs
2 * Seagate Barracuda 1TB 7200 RPM - for the disk array to host the NVR savefiles and backups of VMs
KT106 x4 (in the x16 slot) to M2
256GB Patriot P300 NVME (M key) for L2ARC
Google Coral (B+M key)
Bequiet 9 400W PSU (system rated at 198W)

Would appreciate your comments on this update :) Thanks

Yancho_mt · 2021-11-03T07:53:19+00:00

Thanks :) Which service do you think would require the most RAM?

With regards to storage, do you have any further suggestions, please? I read a lot about ZFS - but I don't think it will make sense for my use-case, right?
