Re: Raspberry Pi Tablet Style Setup

I have a https://kano.me/store/us/products/computer-kit-touch modified with a 4GB Pi4B installed. I've added a larger capacity battery and a fan shim. It is one fat ass heavy tablet, but it is portable. I picked it up on a Amazon sale for half price.

rosegarden MIDI app needs RT kernel?

I've been playing around with music software on RPi 4B, rosegarden seems to be working OK for MIDI sequencing, but I noticed it has been displaying a warning about timer resolution and it suggests switching to a RT kernel. I assume they are talking about a kernel built with the rt-preempt option. Is...

Re: PS3 Bluetooth Headset With Pi4?

Having HSP support seems like a pretty basic thing for a product (Pi4 / Raspbian Buster) with Bluetooth to support. Who is responsible for the packages that would provide HSP support?

PS3 Bluetooth Headset With Pi4?

Is it possible to get a Playstation 3 Bluetooth headset working with a Pi4B? I've seen some complicated guides on how to do Bluetooth audio on Pi3 with Stretch, but hopefully things have moved on from then and I just need to install a few packages.

Re: Am I the only one that still would buy a Raspberry Pi 3b+?

I'd have a use for a 3B if it was available with 2GB or 4GB of RAM. It will never be, so I have to use a 4B in spite of heat and power issues.

Hardware 3D for old SDL1.2 program

Just for a laugh I compiled an old SDL1.2 program I used to work on (OpenFly Flight Sim Toolkit engine) on a Pi running Raspbian Buster. Needed little work to get it compiling and running (just a few changes due to compilers being a bit more fussy these days). It does run but it looks like it is usi...

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

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...

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...
