Usman and I will be demonstrating the Rail-O-Graph in the mornings at the Make: magazine booth. We’ll do a talk at 2pm on Saturday and 12:45 on Sunday on the project. On Sunday at 2pm, Mark Frauenfelder and I will talk about coffee hacks. We’ll have some fun stuff on hand, including Mark’s modified espresso machine, the Florence Siphon brewer I built, a new, miniature version of my hydraulic espresso tamper, and more. Can’t wait to see you there!
