It is time for a reality check, your favorite microcontrollers are probably sold out at the moment or just hard to get. But did you even use all of their features for most of your projects anyway? Most Arduino projects would work on a lot of smaller MCUs anyway. To beat the component shortage clem just uses the brand new ATtiny Generation and shrink-ifies his projects, therefore saving money and power! To do this he needs a UPDI Programmer, so why not just build one?
