When not to Pi: Projects you shouldn't give to your Raspberry Pi

For a long time, I have pictured Raspberry Pi as the perfect computer. It’s cheap, its price is low, the manufacturing costs are minimal. To me, the most significant advantage of a Pi to a conventional computer is: “I won’t feel any remorse after accidentally breaking a Raspberry Pi or ripping it apart.” So why aren’t Raspberry Pis used everywhere? Turns out Pis are known to the State of California to cause [REDACTED], if consumed....

3 Ways to Speed up Raspberry Pi's File Transfer

The Raspberry Pi 4 is the fastest of all Pi. It brings new interfaces to the Pi family: The USB 3.0 port, and gigabit ethernet. Now, people won’t have to be constrained by the crappy USB 2.0 interface of the previous Raspberry Pi generations. The Raspberry Pi Compute Module 4 is even better. A whole PCIe 2.0 port? That’s like 5Gbps of transfer speed! That is enough to enjoy the lightning speed of NVMe SSDs....

How to Install Open Camera Software for Raspberry Pi

An open alternative to propriety libbcm_host.so everyone hates For the longest time I’ve hated on the propriety Raspberry Pi camera stack. It is propriety, it is non-standard, and it is propriety. It depends on the slow and niche Broadcomm GPU that everyone hates. Even more, only Raspberry Pi OS is supported, which means 32-bit operating system only. It is not a good experience for me. Some people might say: “Raspberry Pi OS had a 64-bit beta version a year ago!...

How to Fix 5GHz WiFi for Raspberry Pi 4

For some reason, my Manjaro ARM install on the Raspberry Pi 4 is missing my 5GHz WiFi. It can scan some 5GHz networks, but not my home network. This never happened before on my Arch Linux install, and is very weird. I am aware that this is probably due to wireless country code being set up incorrectly. In Raspberry Pi OS, there is a way to setup country codes for wireless devices through raspi-config....

Ethernet Gadget: Sharing Internet to Raspberry Pi 4 via USB-C

So I was testing some code on my loyal Raspberry Pi 4, ver. 1.2. The Pi is directly connected to my router in another room. Cuz, like, Pi’s ethernet is so much more stable than its wireless. The downside is that every time the Pi had an issue, I had to run over to the other room to recover it. Let’s just say it’s not a pleasant experience. Plugging in and out the microSD card, just to find out the Pi still didn’t work....
