I have a weird problem with my self-built Hyperion Ambilight: It shows rainbow colors when shutting down the AV Receiver and there is no HDMI signal anymore.
My workaround was to disable the entire construction (Raspberry Pi 3 + LED stripe) with a wall plug switch. The downside of this method is the system boot-up time so I couldn't use it as a typical lightbulb. Another downside was the fact that the Raspberry Pi doesn't like being turned off by pulling the power plug: It can destroy the entire SD card, but I was lucky and it never happened to me... Anyway, I need a better solution...
A Raspberry Pi is a great device for a bunch of projects. As a server for your home automation project, a 3D printer controller, a simple NAS or a media center, the possibilities are limited by your imagination only. Nonetheless does a Raspberry Pi, even in the newest generation 3, have its limitations.
While the 1GB of memory and the computing power of four cores with 1200 MHz (3B) or 1400 Mhz (3B+) are excellent for such a small device, the storage - typically an SD card - may become a bottleneck for your application, especially when using a cheap SD card. But can an SSD over USB 2.0 improve this? Let's find out.
