howlong this device working? for example without graphics, only console

I've only ever used it with the desktop so I cannot say how much longer the command line version would last. It is really hard to judge battery life because I usually have devices plugged into the USB ports. It does last fairly long in my general opinion... at least long enough to do some real work.

Hey,
How do you keep the components in place with out a frame like in NODE's version?

It's a pretty tight fit so some components such as the hub board and the battery are held in place when it is in the keyboard case. The USB Ports, the charging module and the slide switch are all glued (epoxy) in place. Note you have to do this AFTER the screen is installed because some of it will hang over the LCD. I did tape the screen in place, but it really is not necessary... the screen should fit snugly in the case.

Plus a dab of hot glue in a couple of places!

Hi BrainFever,
This looks really awesome. I'd love to make something like this. I have a few questions if you don't mind.

The LI-PO battery that you used, what model/size is it?
Which screen did you use? I see a few specced for pi3/2 but no mention of zero on ebay versions in my country. Does the HDMI port work with this screen, I've read reports that HDMI is disabled on screens like these.
Battery life? I'm not expecting much, just curious.

I'm temporarily using a 1S quadcopter battery with a capacity of 380mAh. I plan to replace it with a longer 600maH battery if it will fit. I'm surprised how long the smaller battery lasts... at least thirty minutes... long enough for my intended use.

The LCD is a pretty common 3.5 inch LCD with a built in touchscreen. Most are clones of the WaveShare LCD which is where the drivers can be found. https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(B)

The display uses SPI over the GPIO pins to work the display... HDMI is not used... so it is a little slow in drawing speed.

Anyway, I'll be adding more information in the coming days,... stay tuned and good luck!
