Ask Slashdot: Is There A Screen-Less, Keyboard-Less, Battery-Powered Computer?
Long-time Slashdot reader Wycliffe writes:
So I have a travel keyboard that I love. I can carry my OS on a USB flash drive. There are several options for portable battery powered monitors. The only thing I'm missing to have a completely modular laptop is the CPU/MB/RAM... I can get a laptop but it seems silly to carry around a laptop with a keyboard when I never use the keyboard. I don't need a long battery life, if I need more than an hour then I can find somewhere to plug it in...
I've thought about buying a small box like a Zotac and trying to replace the hard drive with a battery -- but does anything like this already exist...? Also, are there any systems like this with decent specs? Most stuff I see like the Intel Compute Stick are horribly underpowered compared to a decent laptop.
The original submission drew some interesting discussion. Another option is "a good x86/x64 tablet that I can install Linux on" -- especially with a decent processor -- or "laptop-like systems that got rid of the screen entirely... I just need the travel CPU part without the added weight of a second keyboard and monitor." So leave your best suggestions in the comments. Is there a good, lightweight computer that's battery-powered without a screen or a keyboard?

raspberry pi and all its clones/derivatives. Add a USB battery extender pack. Done.
Liberty - Security - Laziness - Pick any two.
It seems that your best solution is to install your OS into a surface/tablet with out a keyboard cover.
Why do you want to do this and what are you trying to accomplish?
One can buy laptops (i.e. Xps developer edition), chromebooks, tablets (iOS, windows and android), and smart phones that can offer you functionality in a portable form factor.
How do these existing options fall down when your needs come into play?
That's the first step to finding a solution rather than some hack job that "works but not really".
There's a nice section on barebones computers there
Kangaroo PC http://www.kangaroo.cc/ makes a few products that might be relevant.
Kangaroo Mobile Mini PC
Intel x5 z8500, internal battery
I have the smaller memory model and it gets hot but seems to be OK, the Plus model with more memory apparently has some heat issues according to the reviews.
I have Fedora 25 on it and I read somewhere it doesn't use the GPU for graphics, but it works fine for me in low demand uses.
The lack of GPU use might also be why I don't have the heat issues.
I can't get the sound out of the HDMI feed, but I think that will work eventually when the kernel gets enhanced.

Just buy a laptop with a broken screen and keyboard. Or look around for one - people tend to junk them because a new screen plus labour on an older laptop is almost as expensive as a newer laptop. You can remove both the keyboard and the screen and cover, it'll be lighter and thinner, and you still have the battery power you want. Bonus points and a Red Green award for duct tape to cover the keyboard hole.
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
Judging by the comments, he's just trying to piss us off.

That sounds like something Casey Neistat wanted in the Samsung Dex: the ability to use it as a regular cellphone and then plug it into a docking station or PC to continue working on the cellphone.

I'm looking for a similar device as the submitter. In my case I'll have a separate screen but I'd like something x86 that runs on batteries with automotive power. So when the vehicle starts the computer just keeps on going. It will essentially run most of the time, sleeping when I don't need it, or powering it off, perhaps with a signal. I need it to be x86 for now because of some software I need to run, so the Pi is out. VGA or HDMI out for the external touch screen. And I need at least two USB ports, or even better, a couple of real RS232 headers I can tap into (for GPS data and talking to an Arduino).
Even if I didn't need x86, the Pi doesn't quite cut it because there's no power management built into the thing. So far as I know it won't suspend or hibernate, or allow me to wake it on a timer like I can with x86 with a BIOS or EFI setting.
It's a confusing summary based on an earlier submission.
Inquisitor already has a substantial emotional investment in a fancy keyboard and a battery powered monitor. Wants a machine to plug these into. Seems to want a 'real' computer rather than a phone.
Attachment is to the monitor, or would have solved this by trading it in for an Android tablet (Nexus 9/Pixel C) with a kickstand - there are projects on xda for porting arch or ubuntu to these things.
You should go with the 1802 membership card....
RCA 1802 w/ 16x16-bit registers, 16-bit address bus and 8-bit data bus
8 LED's and 8 toggle switches for bootstrapping and debugging
Bit-banged serial I/O
Low power consumption
Can even run BASIC
Might even survive the EMP of a nuclear blast if you choose the right components.
Rad-hardened CPU's available fairly cheap.
First microprocessor in space!
Just buy a Intel Nuc and a powerbank for it. It's even more modular than you wanted I guess, buy hey... Modular FTW!
The Raspberry PI would seem to meet your criteria. Battery powering one is as simple as a two cell Li-Ion battery and voltage regulator to bring the 7.4 volts down to 5.
You can wipe windows 10 and put linux on it. Have Mint on mine.

Unfortunately, if you want a full fledged computer, you probably won't find anything smaller than a Zotac. That's the limitation of micro ATX boards basically. And then, unless you are very well versed in the dark arts of DIY electronics, it's gonna be very hard to make a battery work with a setup like that... Zotac and other microATX desktop PCs were not designed to work with batteries, but with a good power supply and AC.
Unless there's some ready made solution, afaik, the power motherboards, components and whatnot needs are very finnicky. Not only they need all sorts of voltages, the overall power draw is too much for batteries to handle.
If you don't mind having a lower powered desktop, I suggest looking for InFocus' Kangaroo PC. Packs an Intel Atom X5-Z8500 which is among the best you can get for the size, has an internal battery, and is the size of a smartphone only thicker. I have one. It's cheap too, around 100 something bucks.

Problem is, it's still closer to Compute Stick than a laptop. And it's not getting better since Intel abandoned Atom.
Other options along the same line of Zotac is Intel NUC and... I think ASUS has some small boxes too. But they are all wall powered.
Last option might be just getting a laptop and taking the screen off I guess. :P I understand why some people want that, but apparently upscaling doesn't make much sense... you also need to understand that even though components on laptops might fit into a smaller form factor, the biggest part of a laptop ends up being the custom made batteries.
As for a tablet which you can install Linux on, I have a Dell Venue 11 Pro that originally came with Windows 8, installed Ubuntu on it, worked fine.
I'm also trying to force a Gole 1 ( http://www.gearbest.com/tv-box... ) to work with Linux but it has been a bit hard. I can force it to run Ubuntu, but neither wi-fi nor ethernet are working - you have to use an USB adaptor. Also, it seems the company used a smartphone touchscreen which doesn't flip orientation along with the screen. But likewise, the Gole 1 has an Atom CPU that is worse than the one inside the Kangaroo PC (Z83500). But it comes with a screen and a bunch of ports, Windows 10 and Android installed, at around double the price.
I'm not sure how compatibility goes, but there were some smaller tablets that ran Windows which I'm not sure if they'd work or not. Ubuntu also had their own smartphone and tablet, and I think they made a fork that worked with some of the Nexus devices... but I think the whole thing has been abandoned:

Anyways, if you find out new stuff post here! I'm also interested.

You'll probably need a portable generator to power it. But it's light, portable and powerful.

Sounds like the hipster assholes that go into restaurants with cameras from the 1890s and spend 30 minutes setting up to get a picture of $12 toast. Then they bitch about how the lighting sucks and they need suggestions on how to get the best shot to post in Instragram for their moms to see.

I haven't tried this myself, but from the specs it looks to be reasonable inexpensive, reasonably small and light, and reasonably powerful:
- Intel NUC (about 1 pound)
- fit-Uptime UPS for mini-PCs (about 0.5 pound and should power the NUC for maybe 1-3 hours on battery, depending on exact model of NUC etc)

Seriously, fuck this question.
Just get a laptop, and if you feel like using a travel keyboard along with it (for some reason), bring that along and plug that in to the USB slot. Just the idea of bringing a portable computer in a bag full of parts is weird. Not like hacker-weird, just like you needlessly fetishize your equipment.
There are no i5/i7 compute sticks that run off battery power.
Slashdot: providing anti-social weirdos a soapbox, since 1997.
I get good mileage from a NUC. Highly portable performant CPU module. Doesn't have battery option, but for me I'd only use it with power available. Myself, I use a laptop and ethernet cable to vnc into the NUC, however I can sometimes borrow monitors/keyboards, so I usually throw in an HDMI cable into my kitbag. You already have travel monitor/keyboard worked out so this might be an option for you, so long as you don't mind being tethered to power.
Do keyboards weigh that much that it's worth removing it?

There are batteries on sale on Amazon for brick computers, so I guess they exist.
Jesus just buy a laptop dude.
Gotta agree. If you can't even shop for an embedded linux SBC, you shouldn't be undertaking to setup one.
this would also allow your modular laptop to use the cell carriers data networks (if you bought a plan) and not just be limited to finding free wi-fi while on the go.
I need a wheelchair van for my son. Help me get the word out. https://www.gofundme.com/wheelchair-van-for-jj
Consider an NUC.
I bought my son a Skull Canyon NUC which is a full i7 6820HQ which I equipped with 32GB RAM and 1TB SSD. Not a cheap solution but great performance in something the size of a DVD case. There are similar and cheaper solutions with anything from a Celeron upwards.

You need to remove it anyway if you're going to cover the area that's exposed by the lack of an upper screen and lid so it doesn't generate keypresses, so why not shed an ounce or so while you're at it? And if the keyboard is still good, you can give it to someone who spilled something on theirs.
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
Not sure why it would generate keypresses. Do you have lots of badly-behaved cats?

Backpack computers designed to provide a VR experience. They are battery powered and without screen or keyboard. But it is a high end PC for gaming. Probably not what you are looking for.
Stop worrying about the risks of nuclear power and start worrying about the risks of not using nuclear power.
One potential gotcha to think about- I'm not sure how many USB monitors require USB3. DisplayLink makes most of the chipsets, and their origins are in USB2 but I'm not sure how well their newest USB3 products do when attached to USB2.
There's the "is there enough data" question (but their DL2xxx chipsets did 1080P on USB2),
And there's the "is there enough power" question, since USB3 offers 80% more juice (0.9A vs 0.5A).
Also I've never heard of anyone try to compile DisplayLink's proprietary drivers on ARM, so more cross-your-fingers.
I suspect it *will* work but some potential gotchas to think about. Maybe you have a different idea for a portable monitor than me, dunno, but these USB powered things are what I think about.
That's the joke bro
A Chromebit or Chromebox as described here: http://www.androidcentral.com/... coupled with a portable Bluetooth or USB dongle-connected keyboard and mouse should work. We've been playing with these for signage but trying them out at home or at hotel rooms. They plug into HDMI TVs or monitors, and you can even install Ubuntu on them for a full stand-alone experience. (See https://www.reddit.com/r/chrom... for example.) Yes, you can find Windows alternatives, but what's the point?
It's basically a computer you wear on your back. It was designed for use with a VR headset as the screen, and as a result it's pretty powerful. So if you need x86, powerful GPU and battery, that's one way to go about it.
