hi, project creator penk here, thanks for the comment, "we don't know" is the honest answer we can give at this moment, since we hadn't ordered any parts. For your reference the first batch (10pcs) EVT boards is about ~90USD a piece: https://i.imgur.com/anUASlT.jpg

"we don't know" is not as good as "we don't know, but it won't be less than the material cost, which is currently X" would go a long way towards taking the people you want to get excited about this product seriously. We understand how "things cost money" works, but going "we don't know, figure it out yourself" is not a nice thing to tell people who are actually interested in what you're making =) Even updating it to…

Fair point, will update accordingly. I hesitate to say anything because we are getting mixed signals from Chinese manufacturers....

A tablet, built on open technologies, with a wide variety of ports, and replaceable parts?

Count me in. I would replace my laptop with this.

Will see if we can source any higher resolution MIPI DSI display parts, the current one's cheaper though ;-)

Is it possible to buy higher-resolution display parts individually, or is there a minimum order size? Also, most Android/Windows OEMs low-end tablets are 1280 x 800, so I'm guessing higher-res screens strain their batteries and GPU too much for them to be viable?

The 11" Pinebook ships with a HD display so they are available, don't know how big the production run of them is though.

Reminds me of this project someone was working on: https://hackaday.io/project/164845-dlt-one-a-damn-linux-tabl... They started off using the compute module, but ended up switching to the Nvidia Jetson Nano. Both of these projects make me wish for a world where a standard pin-out in this SODIMM format arises and we could see some inter-operable competition like we have with PC desktop parts.

There are just too many single board computers! We've chosen Pi Compute Module for its ecosystem and community.

Looks like vaporware. Doesn't announce a price. I won't hold my breath.

Also, double-opt-in for e-mail should be the default now. This screams 'scam' to me.

I'm quite interested in how you integrate power management into the PI. There's very little in the way of 'real' power management solutions for the PI and a myriad of 'power down when the battery is low' solutions ... is a decent, cheap, reliable fuel gauge hat just too much to ask for? :D

We're using the MCU to swtich power source between USB charging or battery, using it's ADC to serve as a voltage divider to get actual AD value from the battery, and a MP2636GR chip for charging and voltage step-up. So yay battery percentage! ;-)

How do you do the switching? Using a MOSFET or something else?

Handle and design loosely reminds me of the OLPC. It's cute (and aptly-named)

If you had read the thread before commenting, you'd find that the developer of this used to work at Canonical, which lends them at least some credit.

It is great that you release this info early, including the “we don’t know”, as someone who does know may show up and help.

Man this has come a long way. I remember my first Pi I wanted to do this SOO badly. I wound up doing it with a 48w/hr battery and a 7" non-touch automotive backup camera screen. [1]

This was just after the launch of RPi1 and well before Adafruit had all the cool parts that just work out of the box.
