Re: RP4 USB Battery Power - E Marked Issue

Probably not that helpful but, I picked up a cheap power bank battery from Aldi. It works. 10000mAh wireless portable power bank UX URBANWORX model UX10000PBQi. It was only $30 Australian. It's rated at 3.1A 5V on the USB C output.

Re: Pi4 laptop or Tablet

Battery life 3h 57m under light load of web browsing and e-mail. The powerbank just switches off without warning, I didn't get a low voltage warning from the Pi first, not ideal. Are there any power saving features on the Pi4B I can make use of to extend battery life a bit? Maybe ditching the SSD an...

Re: Pi4 laptop or Tablet

Making some progress with the "PiPad" project. The Kano Computer Kit Touch is now a "PiPad Pro". Upgraded to a Pi 4B 4GB with a 10,000mAh battery and a 250GB USB3 SSD. http://ariel.its.unimelb.edu.au/~gjo/PiPad1.JPG http://ariel.its.unimelb.edu.au/~gjo/PiPad2.JPG Still a few issues to resolve: I can...

Re: Pi4 laptop or Tablet

I wonder if it would be possible to do automatic screen rotation? Pi sensor hat required?

Re: Pi4 laptop or Tablet

My cheap Kano Computer Kit Touch has arrived. I've booted it up off a Buster Raspbian 32GB micro SD I was using with a Pi4 board. Seems to run remarkably well considering it is only a Pi3 board. The touch screen worked without any changes. Screen is 10" 1280 * 800. The supplied Pi3 is custom, it lac...

Does any one know which "powerbank" batteries will safely power a Pi4 for sure? To answer my own question I picked up a cheap power bank battery from Aldi.

Re: Raspberry Pi 4 usb boot?

you guys know that noobs allows you to install right to a usb device right? Tried that on a 4B yet? And to misquote your(?) own argument what serious user uses Noobs? I installed NOOBS on a old 4GB micro SD I had lying around. Plugged in a USB3 SSD to my Pi4 and selected it as the drive to install ...

Re: Raspberry Pi 4 Heatsink vs Fan vs Flirc Case

Youtube video of Pi 4 FLIRC case testing: https://youtu.be/vkLr08K0c1E Sounds like it is perfectly adequate. I've got one on order for my second Pi 4. I have a case with a small fan and 4 small heat sinks, idling at 42C ambient 22C.

Re: Pi4 laptop or Tablet

Does any one know which "powerbank" batteries will safely power a Pi4 for sure? Most USB C power banks are rated for 5V 3A, but they are "chargers" rather than power supplies and have various funky circuitry to do voltage boost to rapid charge some mobile phone products. Given the resistor issue tha...

Re: Pi4 laptop or Tablet

Not sure where you gathered that from, but powering the Pi4 from the 5V & Ground pins on the GPIO expansion header should work fine (that's how the PoE HAT does it). Great, that means the only changes to the Kano wiring would be a micro HDMI to HDMI cable or adapter. and upgrading the power bank to...

Re: Pi4 laptop or Tablet

suspect any laptop style case will require some sort of active cooling. The Kano tablet case is a huge wedge shape, plenty of room for active cooling. It seems to supply power through the GPIO power pins which I gather is a no-no for the Pi4. plenty of scope for rewiring things though. This video s...

Pi4 laptop or Tablet

Are there any Pi4 laptop or tablet kits available yet, like the Pi-Top laptop or the Kano tablet? The Kano Computer Kit Touch looks like it could be fitted with a Pi4 but I'm guessing that a beefier USB C battery pack would be required and some of the internal leads would need to be changed, micro H...

Re: Pi4 as Desktop computer

I've just setup a Pi 4 4GB with a 250GB USB3 SSD as a desktop system to replace an old Pentium 4 2GB RAM 120GB PATA HD running Ubuntu 16.04 LTS. /boot on micro SD, /root on the SSD. Seems like quite a nice cheap upgrade to me! Got a small issue, I cant watch ABC TV iView (Australian free catchup TV ...
