How I hacked CASIO F-91W digital watch

Bringing NFC contactless payment capability to a true classic.

Habe es geschafft, das Armband meiner Casio F-91W zu wechseln. Das Original-Armband fing an zu brechen und ich wollte mein selbstgemachtes stattdessen einsetzen. Allerdings ließ sich der eine Stift nicht herausschieben. Habe letztendlich das Armband raus geschnitten und den Kunststoff um den Metallstift weg geschnitzt. Den widerborstigen Metallstift dann gewaltsam per Elektrozange entfernt. Ich hatte noch welche, die auch gepasst haben.

Forgot to take a before and after picture, but it's there in the video... Nice little improvement.

Now to get back to studying for the Bach cantata in a few weeks.... (BWV 197A)
