I’ve been using one of these for a while now, and just made another for a friend. I have plenty more Old MacBook broken keyboards to play with if anyone wants one. Track pad works as well.
I use mine to allow me to use my laptop in a more ergonomic way. Still trying to hack an external trackpad – any tips let me know.
Making this was shockingly easy details here http://todayimade.co/items/118
