Overclocking SD cards on the Raspberry Pi

Warning: Overclocking SD cards can corrupt your data and possibly damage your SD card! If you want better SD card speed and have an UHS-1/3-capable SD card, you can make the Pi run it with more than the standard of 50 Mhz. I tried this with a Rasperry Pi 0 (the non-W variant) and aContinue reading “Overclocking SD cards on the Raspberry Pi”

Running GUI applications over SSH on a Raspberry Pi

Sometimes you have a RPi attached to a screen, but no keyboard or mouse attached and want to run GUI applications on it via SSH. This will also let you cross-compile RPi applications on a development machine and test them on the real machine. Prepare the RPi for ssh access To enable SSH access onContinue reading “Running GUI applications over SSH on a Raspberry Pi”

I have an Asus UX3410UA laptop. To silence the fan I use ACPI calls to adjust the fan tipping point. See this. This needs the kernel module “acpi-call-dkms” for being able to run the “acpi_call” executable. If secure boot is enabled on a computer this module will not load if it is not signed andContinue reading “Signing your kernel modules on Ubuntu 16.04”

Useful Linux scripts etc.

A better find I keep using the find command in Unix as such: “find / -name SOMETHING” (Yes, I know there’s locate, too). You always get an error message when you hit a directory you don’t have permissions for, but I usually don’t care about those directories anyway, so it makes sense to pipe thoseContinue reading “Useful Linux scripts etc.”

Raspberry Pi setup / configuration stuff

I keep forgetting the stuff and always start over when I have to reformat or the SD card breaks, so here’s a collection of useful tidbits when setting up and configuring a Pi. I’ll expand this page whenever new stuff pops up… Adding a root password When you try to su, you can’t when noContinue reading “Raspberry Pi setup / configuration stuff”
