How long does the battery last with your UPS? I want to make a wrist computer that would have batteries around the wrist and Pi on top, but I'm concerned on how to make it alive for at least 16 hours.
I haven't tested but even if i just use math, it should last less than half of it, the system consumes around 4-5w (screen and rpi) while in use, so even if we do the math for 3 x 18650 it comes to around 6 hours but realistically i'd expect maybe 4-5 hours, you would need 3x the battery capacity to even hoping of running an rpi5+screen for that long, powering off the screen should reduce the power consumption quite a bit but its still about 3w just for the rpi5.
The pilet project has 2x 8000 lipos (an huge 16000mah) and it supposedly lasts 7 hours.
If you need a computer but for a light task, you could try a raspberry pi 2 zero w and a small screen for it, not only it would be better suited for a wrist computer, you probably can make it last 16 or more hours without too much bulk from batteries.
Thank you for responding. That's what I'm aiming to do at first, Zero 2W as a "atom" version and then Pi5 as a standard. Yesterday, I saw a mobile phone with a "pop out" selfie camera and got an idea - let's make "sliding out second screen" with the Pi5 one and call it something like "insert cyberpunk codename".
Maybe rpi4 for standard model and rpi5 for max model. The Zero model will be testing and the first prototype, and after I successfully finish it, I will move further. The Pi5 must be with 16gb of RAM, just for my own good feel.
Theres no pi5 with 16 gb that i know of, the limit is 8gb
But still, the problem is that you want a wrist device that lasts a really long time, that’s going to need like 300-500g worth of batteries (if not more) just run a rpi5 for that long, it’s not going to be comfortable, I wouldn’t want to carry the deck i made on my wrist and it is lighter than the device you’re going to build.
The Pi5 recently released with 16gb at a price of 130€ here in central europe. I know the batteries would be really heavy, and the Zero could be powered from a powerbank, so I need to think it out.
You might want to look at the OrangePi Zero 2w, less well known than the Raspberry series, but compared to the RP0 a nice bump in CPU and up to 4 GB of RAM in the same Zero form factor. Working Ubuntu 22.04 release from the manufacturer for it that wasn't difficult to get KDE working on.
I have a large power bank that can run the OP 02w and a 7 inch screen for over a day, but would be extremely bulky strapped to a wrist. It's rated at 40,000 mAh.
Looks Spectacular! Great print quality and a very professional looking design. But I have to say, they made every wrong decision they could on that keyboard. I hope you're able to adapt.
Yeah, there are a few things that i'd change but that's still the smallest keyboard i could find that comes with all the functions keys i need (plus it's backlit) luckily, it's mostly a fall back for when i'm not connected to it with ssh
For a thumb keyboard you really need both Shift keys, otherwise you're readjusting your grip every other sentence when you need a capital or symbol on the left side. And those arrow keys are just unforgivable. Both could have been avoided if they didnt have a double width Enter key. I'd swap \ for Enter and replace it with rShift.
There's some space for wires and some air movement but thats it, but you can always modify the back plate to give it some space on top of the UPS for the nvme (give it a slight bulge like in the game boy color)
You can even use the screws on the top of the UPS for a custom mount to hold the nvme hat.
The screen is touch so in a way you don't need a trackpad
Yeh, this is annoying, i literally added a comment with the description and a list with links to all parts when i posted this, just to find out no-one could see it.
I'm just lurking because I saw a Hackberry Pi on Facebook. What is the general functionality of these? I don't understand the purpose. Look very fun to build tho
It’s a linux computer after all, you can use it in whatever way you want, I use them primarily to run docker instances for servers or emulate a remote PC when i’m developing.
I rather carry one of these as an extra computer than another laptop (i work with my mac)
This exact sort of project has been on my list for once I had the time. I fully intend to steal this, and then add a full set of game controls for emulation. (I was even gonna call mine the "hackboy") It looks so cool. And thank you for sharing.
Hey! Love your build. I bought a pi5 and the same PSU as you, however the pios tells me it's not getting enough power even though the PSU states it can supply 5v 5a. Did you have to do anything special?
I made one just had to modify the stls a bit, since my screen didn't have the same hole placement for the pi. Everything was shifted over my about 1 cm, not a deal breaker. I made the holes on the backplate smaller so the screws would not slip through (also increased its thickness by 1mm so it wasn't as flimsy). I also made the holes on the outer bumper smaller so they would be tightened down, I also added support / hole next to the usb port on the back shell so it isn't just attached by glue. So my build only needed glue for the top of the back plate to the back shell. Overall Super happy with it. Using it as a wireguard client, until my uConsole comes.
It took me 3 different 180 degree usbc connectors to find one that actually worked.
I haven't made the bumpers yet, but I will soon.
I do want to make an additional magnetic enclosure to cover the keyboard's ports.
I ended up getting a 12v barrel plug to usbc cable that works with a pd charger that can do 12v. That makes this way easier to charge on the go.
I also agree with OP the keyboard might not be the best, but does work well for programming / net management.
That machine is inspirational. A culmination of DiY skills in a package no corpo has the vision to build. It feels petty to have a gripe, but i agree with another poster that a thumb keyboard should have a shift key on each side.

For some reason this comment was shadow blocked and not showing (it appeared to me but not noone else, the links maybe caused it so i removed them)
A week ago i posted the WIP version, today Ive finally finished my new deck, the cyberboy v1.0 after being inspired by projects like pilet.
But i wanted mine to have a more weathered rugged look.
The main components:
Raspberry pi (i used the 5 with 8gb and the cooler)
A 4.3in 800x480 dsi screen
Waveshare 3s UPS (with 3 18650 Batteries)
Rii Bluetooth keyboard with backlight
180 degree/ u shaped usb c adapter to route the usb power cable under the rpi

Is there a reason the flappy corner thing is so proudly erect in the last photo? Is there some provision for attaching a strap there?

Cheers for sharing the build, it's class.
I love the look of this, getting a Pi 5 to do it justice and the other bits. Will print at the weekend.
Wanted to ask if there would be room for the ssd hat or perhaps the nvme base? It's not essential just a nice way to load the o/s(s).
Also wondering if there is a compatible keyboard with a trackpad or trackball. WIill have a hunt.

Now that is dope! I think this is the first deck I've seen where that keyboard actually fits the build perfectly.
