Re: Pi4B 4GB freezing

After reading through this thread https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=262649 I thought trying the over_voltage=1 in /boot/config.txt was worth trying. This seems to have done the trick. My question now is, did the 20200212 fixes correct the issue and is it now safe to remove the ...

Pi4B 4GB freezing

I regularly update my Pi4s with apt-get update, apt-get dist-upgrade and now one of them has started acting flakey. Both are similar configurations, noobs /boot on SD card with / on Samsung T5 USB SSD. The main symptom is it freezes at the the login screen after it has been idle for a number of hour...

Re: RPi4 external USB3 SSD Enable and Check Trim

Interesting topic. I had been naively assuming that fstrim would be happening automatically on SSDs. Should fstrim also enabled on SD cards?

Chromium Youtube Video Playback

I noticed there has been a recent batch of graphics related Raspbian patches. On my Pi4, Youtube video playback with Chromium seems to be much lower quality now, blocky with visible aliasing.. Has something happened? I know there are a lot of variables here, but something has definitely changed on m...

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.

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.

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.
