An update about the android app thing: no, it still doesn't work. Spent the entire monday figuring out why the app kept crashing directly after startup. Crashes can be caused by anything, and I don't have clear feedback from the device I'm testing the app on to see what's wrong. For some reason, it seems it cant find a certain object (a textview) for a given reference. Even Stackoverflow can't answer some of my questions anymore.

Did things go better today, then? Well... Last week, I tried to make two ZigBee modules hooked up to ESP32's communicate with each other. Through serial communication, it finally worked, until I changed the code so it would return the PWM value of a digital pin. And then, it didn't work. It looks like I'll have to get really deeply into AT commands, to make sure that the modules can see and communicate with each other. Yay.

Figured I might as well treat myself to some black friday shopping. Bought a new SSD for my laptop, since the one I have right now is a bit small. Tried to clone the drive to the new SSD today, but the disk manager wouldn't initalize the disk, only gave the error "fatal device hardware error". Most solutions on the internet only work for drives that have already been initialized. There is a chance that the SSD was dead on arrival. Not really in the mood to go through the process of returning it.

Thought I was finally done when I ordered the sata cables last week. I figured the cable to the HDD shouldn't have to be too long, since the sata ports are right beneath the HDD tray. Guess what? The 10cm cable I bought is just a bit too short. Ordered a new cable.

Okay, but I could still turn the computer on with the HDD tray half displaced, right? Yes! I thought, when I remembered that the Fujitsu has a VGA port, and I have an old monitor with a VGA port. So there should also be a VGA cable somewhere, right? Nope. Still, I managed to get a VGA cable from university today, so I'm looking forward to finally firing this thing up. I just hope I got the whole "burning an ISO to a usb drive" process right. I thought I had a cd with an old Debian-installation laying around somewhere, but I cannot for the life of me remember where...
