Decided to go with a AA battery instead of the button battery on this version. The vibrator drains the button batteries very quickly and I couldn’t find a store that carried holders for them.
So I attached the switch to the AA battery holder in order to have a morse-code like controller.
Telling Time:
Initially the device would only tell the only the hour but the Haptic Clock by Che-Wei Wang solves the problem by having the hours vibrations longer, and the minutes vibrations shorter. You also want to “compress” the minutes into chunks to facilitate the counting. So I decided to group the minutes by tenths like this:
xx:00 to xx:10 = 1 vibration
xx:10 to xx:20 = 2 vibrations
xx:20 to xx:30 = 3 vibrations
xx:30 to xx:40 = 4 vibrations
xx:40 to xx:50 = 5 vibrations
xx:10 to xx:20 = 2 vibrations
xx:20 to xx:30 = 3 vibrations
xx:30 to xx:40 = 4 vibrations
xx:40 to xx:50 = 5 vibrations
Also when delivering the times, adding a rhythm to each number would allow for a telling the time but feeling the rhythm of the number instead of having to count each single vibration.
