This is independent of other projects I have asked for help on. I'm just looking for anything done similar to my plan.
I am visually impaired. So tend to find most laptop pi projects way to small for common use. But also want an experimental bed for pie projects and experiments in genral.
So my idea is. I'll get a aluminium briefcase like case. Mount a 18 plus inch portable USB c powered display into the lid. It would also be nice if I could have my 15inch display fold out on a vesa mount. As an extra.
Inside the case id like to mount a large 18650 or similar lifepo4 batt. I'm thinking 4s 4p with a BMS so I can power usb 100w output with a 12v hub. This should allow out put to multiple monitors and a pie or 2.
I have a great small wireless keyboard and mouse. That could be popped in and out.
For the main board currently I'll use my waveshare CM4 poe board b with my 32/8 gb cm4.
But long term the itx cluster board looks good. When I have a bit more cash.
The main idea is it will allow me to connect multiple pcie riser cables to the boards via a 4 way wave share pcie switch to start with. Providing space to mount different boards and options as I change projects.
As folks may have seen from other projects. I move between home and my tiny narrowboat I share with my brother. So this will be more about being able to port multiple pie projects as much as being a usable PC type thing.
So if anyone has seen or worked on a project that may point to cool ways to mount this. I'd love to see them.
As I do not have a 3d printer. And cannot really argue the value for as rare as id use it. I am thinking alliminium plate cut and riveted to mount boards etc to the inside. But would love other ideas folks have seen or can come up with.
Sorry I am expecting no here. But cannot help but hope someone knows a way around the limitation.
I have a project where I plan to use an nvme on a waveshare mini b io board.
I am just now learning my way around CM4 pies. So purchased a few parts to experiment before fitting to manage stuff on my boat.
Unfortunately I did not know enough whan I got the dev cm4. Seeing as the cost difference between Emmc and lite was tiny. I decided there was little to lose with getting a Emmc one. Not knowing the EMMC uses the same pin address as the SD slot on io boards.
I now know this will mean the SD card port is not available. As I plan to use that to move software updates.
I was wondering if anyone knows a software way of enabling the internal sd port. IE basically disabling the EMMC.
If not ill just set up with a USB SD reader so all my cm4 can run identical. But if I can use the one on the board. It will be simpler. Maybe have some option to reboot the boat cm4 in either option with an emergency os on the emmc in the event of a fault.
Hi again folks.
I am looking at a small project. Once again for my boat.
As this one really has very little need to write. Just regular temperature logging with time from multiple sources.
I am considering setting the pie to store all temporary files in memory. Running the main os from the SD card. And just using an extra USB storage for logging temps etc.
This should hopefully leave the system needing very little maintainance. With just the USB flash drive prown to wearing out every couple of years.
I'd be greatfull for any links to folks who have set up similar systems.
Or other ideas on safe low maintainance ways of running a pi zero os.
Hi. I am looking at using a cm4 and Waveshare mini io board. For a project I am setting up on my small narrowboat.
As the tiny antique single cylinder diesel engine. Means the boat suffers from a fair bit of vibration. And this will be the first time I have used a CM4.
I was hoping some folks could share there experiance/advice on using CM4 boards in similar rough environments.
I am planning to build a system mounted to din rails with rubber pads to absorb some of the vibration. But any other experience other have can only help.
