My interests include tinkering with electronics -- handhelds in particular. Completed projects include an original Gameboy Advance with a backlit display, and converting a broken DS Lite into a GBA. Upcoming project: upgrading the HP48 series calculator memory. The HP48 is an old graphing calculator that is now no longer in production. However, it has been a favorite number cruncher for me and has served me well over the years.

I am also a big fan of calculators in general. So you will also find a number of videos related to graphing calculators. Right now, my focus is on the HP Prime, a relatively new graphing calculator by Hewlett Packard which sports a touchscreen.
