Truth be told, Audiovox has already perfected the digital post-it note with the DPF711K, but if you're all about flexing that DIY muscle and giving everything your own personal touch, we've little doubt that you'll prefer this iteration. Granted, this isn't the simplest of projects we've come across, but if you can handle a fair amount of soldering and aren't too bad at following directions, you may actually be able to pull it off.
