Printing a handheld PC

Roberto,

Here's link to video by guy who made the little Banana Pi UMPC that I had (referred to prior post...)
that was running Armbian.

And here's his video of his Universal UMPC that had a 'x86 stick' attached to back of display cover. This created a modular CPU solution, easily swappable, if you don't mind the bump on case.

Maybe there's info that might be useful for you.

Best,

Mark

Thank you Mark. I like this project a lot - It's a neat looking little machine and clearly this guy's put a lot of time into the design. I've toyed around with the idea of using a Compute Stick or similar - This would also seem to allow machines a good bit smaller than mine, as in the videos you've linked. The biggest issue I've come across is the lack of neatly integrated battery management i.e. a battery and charger than the OS is aware of and able to control (or at least react to). I looked a bit into a USB protocol that's used by some UPSes whereby the UPS appears to the OS just as a laptop battery would - I believe there have been some efforts to implement this on an Arduino so it should be possible to take one of the various 'battery management' boards designed for the Raspberry Pi and interface it to a Pi, Compute Stick etc. via an Arduino (or similar microcontroller) pretending to be a UPS. I didn't get beyond looking into it because this level of tinkering is beyond me - I can do some basic Arduino stuff but when we get to USB device descriptors etc. I'm lost.

It's always interesting to see what others are doing, and often they've tried something I wanted to try which is very useful - I really need to document my project better but I'm prone to re-using as many parts as I can so most of the time it's little more than a pile of parts on a bench - I can at least start a bit of a journal of what I'm doing though.

I found a project called Nano Pi 2 UMPC on YouTube.
The 3D printer files are on Makerbot Thingiverse.

Pretty neat, although the project is from 2017 and uses Raspberry Pi 2.

Happy New Year, stingraze!

Yes, this guy has had several iterations of this.

As I recall, he had a version in yellow.

All these things make me want to get a 3D printer and start making something fun.

Happy New Year, ArchiMark!

I want to get a 3D printer someday soon too, to make these cool handhelds.

I've just come across this project.

Some nice pictures on how it's made, etc.
The download section has the STL 3D Printer file.

Also, be sure to check out another project from the same guys.

Nice, stingraze!

Just wish it had a hinge between keyboard and display....so, you could fold it in half....

Yes, I agree the hinge would have been nice.

For those that who don't know already, reddit and other sites have nice cyberdeck, which is like a big handheld in SF.

I thought this project was pretty cool:

It's pretty interesting to see what people can imagine and make.

Thanks for the subreddit suggestion! Some really cool builds in there.

Glad you liked it. The whole cyberdeck thing is pretty cool.

Thanks for the latest links, stingraze.

Some pretty funky looking devices in a steampunk sort of way......

I can see spending lots of hours playing around with this stuff.



Mark

You're welcome!
I will have to research more on the origins of cyberdecks. Probably to do with Neuromancer etc. and other SF novels a lot.

I just ordered parts for this
It looks like it could be my new favourite device for my workplace. I think it is awesome for firmware upgrades / SSH and read data over a USB/RS232 converter.

As soon as I get new stepper drivers for my 3D printer, I start printing all the parts.

Stefan

Happy to hear that!
Post your machine once it’s complete!

A little tangent, but a Japanese guy put the Raspberry Pi Zero in a Nintendo DS Lite.
I hadn't thought of this idea...



He also has this neat Portable Raspberry Pi he made on flickr:
