Electronic pounds are very common and almost every families’ homes have. However, most of us will forget about it or put it aside deliberately because afraid of knowing their actual weight ! Thus, my little hack project is hacking a chair to replace the electronic pound, also, the hacked chair will not show users their weight by using numbers instead of it, different sound effect or sentences will be used according to different ranges of weight from 0kg to 80kg (30-50kg / 51-65kg / >65kg).
