hey @bishoyabd welcome here 
can you tell us more about “Cactus” how it came to be, and what do you think is needed to grow ?
since you showed interest in the coffee sorter machine let me introduce @matthias who is leading the project, also @imake Islam who is going to contribute to the project while working on some interesting stuff and @Bakr who is joining us from Egypt as well.
do you have a specific interest or something that you want to dig deeper/ play with/ learn more about during the coming months ?
