It’s $168 plus the cost of a CM5; while it is cool, I would worry that the $200+ device would end up in a drawer…

I suspect an awful lot of us have a mausoleum of abandoned projects where this would feel right at home and is probably downright budget friendly compared to some of the other residents interred there.

The drawer that holds my Arduino, Raspberry Pi, and clones thereof is dangerously overpopulated as it is, but I think I've finally learned my lesson: Now I always have a cooling off period of hours after putting something in an online shopping cart before I click "buy" to see if my interest was just a passing one (usually the case).

At least this is small. A few years ago I bought a Sun Enterprise 450 for dirt cheap and I've been regretting it ever since.

I was looking at $400 modded iPod Classics this morning and my better judgement avoided a new member of the "neat projects" drawer.

What do you mean - I will get back to that project some year. It hasn't been touched in 15, but I'm still going to get back to it - sometimes around my 2700th birthday most likely (I'm trusting someone else will advance medicine such that I live that long)

Mausoleum sounds way more dignified than my junk drawers of half done projects!

If I had a 3D printer I’d build this one for sure. Or the 3D printer would sit in my junk corner. One or the other.

Hey, you gotta send these things off with some dignity - it’s not their fault I’ve got ADHD and poor impulse control.

neat product but what a garbage company that was

it's cheaper than the flipper zero. Something i have found i mostly don't use apart from keeping a copy of my apartment card.

Yeah... for me, my vision is rather deteriorated, just looking at the size of things in the screenshots I can tell I'd have trouble using it. I can't even use the Steam Deck for that reason. At least my daughter and SO get use out of it.

For about 5 years before Android/IPhone, I used a nokia phone that opened with the screen in the middle of a split querty keyboard on the phone... that thing was perfect for notes/text. I really wouldn't mind something like that or even this device as long as the text could be set to something reasonable for my poor vision to use. I have to max out my accessibility/text settings on android and that's a stretch at times (also exposes so main UI failings).

You could let eBay be your junk drawer.

The CM5 also doesn't have hardware video decoding, making it weird for a handheld device.

I would shove any other cm5 compatible device into this than the actual cm5.

extraduder_ire 3 days ago||
I don't know about other formats, but the CM5 specs sheet says "4K60 HEVC decoder".
DannyBee 2 days ago||
Yes, you are correct. It has a 4k60 HEVC decoder, i forgot about that.

It has no h264 encoder or decoder or other encoders or decoders.

I know this from watching lots of people try to use it on 3d printers and discovering that their camera streams now take tons of CPU[1] after "upgrading" from a pi 4b to a cm5.

In any case, from just about any perspective, you are better off shoving a rockchip based cm5 compatible board in this.

[1] the commonly-used logitech cameras used to do h264 streams, but they removed the h264 encoder chips in all of their models a few years back, without changing any of the model numbers. All the current ones are like yuvy420 at 5fps or mjpeg at 30fps. Even for something like the mx brio. But for things like the c920,if they are old enough, they do h264, and if they are new, they don't.

Is it possible to buy a standalone Blackberry USB keyboard? zitaotech store has been out of stock for months.

There is a chip that can control keyboards with I2C interface, the ADP5587, handles all the delicacies of button pressing:

Nice. there's also a project [0] that uses the RP2040 to talk I2C and present it as USB HID, created in service of the beepberry [1]. Now that I think of it tho this could be made into a very miniature home theater PC remote, a la the Logitech DiNovo

Something to hack, but I don't see how to easily type braces and parentheses. Looks like a non-starter to me because for me, I hack by writing in languages that require parentheses.

In the HackberryPi CM5, does that pointing device (which IIUC is repurposed from Blackberry hardware) work like a joystick/TrackPoint?

Can you move smoothly at all angles with it, well enough to use the desktop GUI?

Yes. I tried to find a good video showing it, this one from the same creator shows it being used as a mouse and you can see it works pretty well: https://www.youtube.com/watch?v=568L-P2tBwc

Thanks for finding that. Nice. Starting at 14s in the video, looks like it's doing both coarse and fine movement. I don't know whether it would have to calibrated for best balance on the tiny display, but looks like it will probably work pretty well.

I want something the size of a TRS-80 Model 100 - something I can type on.

You may want to look into the clockwork pi's devterm.

Fwiw, for other projects you can look at other SoC brands than Raspberry, such as OrangePi, BananaPi, ClockworkPi, KickPi, Pine64, Rock64, Odroid, Libre Computer, Radxa, ArmSom, Onion, Udoo, NVIDIA Jetson, ASUS Tinker, Khadas. I was kinda blown away by how many there are. Ask ChatGPT for specific models and feature comparison.
