Time to test the HiFiBerry as well.

The Raspberry Pi Camera module does seem to work for the music player, but it did cause me some headaches initially.

The first problem I encountered seemed to stem from a sloppy physical installation of the camera. Once I removed it from the Pi and inserted it back in, it worked.

The second problem seems to be that by default the camera cropped the sensor data, so the QR code couldn’t be read as close to the camera as I wanted. Adding --prescale=640x480 as and argument to zbarcam appears to have solved the problem.

Tomorrow I’ll try using the HiFi Berry Amp2 as well.

It appears that I was quite good at documenting my work on the music player, so I’m up and running again now.

Previously I’ve used an old USB webcam (actually a PlayStation eyeToy Camera) as the scanner and it has worked fine. However I wanted something different in the long run, so yesterday I bought a camera module for the Raspberry Pi.

The main thing I’m doing tonight, apart from getting back to where I were, is to test whether this particular camera works or not. So far it has not been plug and play but maybe it was foolish of me to expect that. As I’m writing this I’m doing a apt-get update and apt-get upgrade and then I’ll have to do some configuration in raspi-config.

Also, I’m starting to get reaaaaaaally tired so I’ll probably call it a night pretty soon. I blame daylight savings time.

Linn and I finished watching Stranger Things Seasons 2 and 3 yesterday and since we don’t have any other show queued up, now seems like a good time to resume my work on a music player for the kids.

Right now I’m mostly trying to figure out how far I got the last time I worked on it.

Problemet är att varje sådan här välmenande men verkningslös symbolåtgärd gör risken större att folk inte går med på de svårare och viktigare klimatåtgärderna.

So I guess I’d very much like any recommendations of easy to use shopping list apps where I can also share lists with Linn.

iOS 13 managed to turn inputting things into Remainders from a simple thing into an insanely enjoying one. Having to pause for a second between pressing return on one item and starting to write the next one is terrible when compiling a shopping list.

iOS 13 bug of the day: Deleting a file in Files always results in a blank view and me having to navigate back to the directory in question manually.
