Re: Image viewer with transition between images

Hello, is it possible to write-protect the sd-card after setting everything up? My plan is to use the image viewer in a shop-environment (behind a tv screen) where the main power will be switched off for the night. I want to prevent damages to the image. (Hallo Wolfgang, wir sind gar nicht so weit v...

More and better information about hardware revisions

Not long after the Pi4 was out there have been reports that certain USB-cables won't work for powering the Pi4. That has been confirmed by Eben Upton and he talked about a possible board revision fixing it. He never promissed that fix and i now strongly doubt the arrival of that board revision will ...

RasPi4 - active cooling

Has it ever been considered to produce an official case with a build in fan? Pi4 is out and every review i've read so far talks about the increased heat and thermal throttling. So depending on what you plan to do with your Pi you will have to consider adding at least a heat sink to it. Currently i u...

Does the Raspberry Pi 4 officially support micro-SD cards with more than 32GB?

With current versions it is at least not recommended to use cards with more than 32Gb, as this seems to cause some problems. I know that it's technically possible but you have to reformat the card to Fat32 and somewhere I read about having to add some lines to the config for stability reasons. Is th...

Re: Motorola Lapdock Atrix with the Pi

what about connecting it to the gpio port instead of building it into the cable?

would this one work?

Re: Motorola Lapdock Atrix with the Pi

Using a lapdock with a Pi ZeroW is fun for retro gaming but hasn't got enough performance for pretty much everything else. A Pi 3B starts up but randomly reeboots. Most likely because the lapdock doesn't provide enough power. Voltage doesn't seem to be the problem because the low voltage sign never ...

Re: powering question

It Works! The display controller board has two different inputs: a round one, like on a laptop and one 4-pin. Power comes from a 12V 4A DC adapter and goes into the round power input. I use the 4-Pin connector as a power out (because both inputs are directly linked to each other on the pcb) to feed...
