Release 04/12/2016: Nothing Lasts Forever
Glass, Aluminum, Custom PCB, E-Ink Display, AA Battery
ø30mm x 100mm
Limited Edition of 999,999
Each press of the button increments the counter by one. If and when the counter reaches 999999, the devices stops functioning.
Each device is engraved with its edition number.
Electrical and mechanical components and their associated minimum lifecycle:
-The e-ink display has a working lifespan of about 50,000 hours, which translates to about 90,000,000 refreshes at 2 seconds each.
-While the button is not engaged, the electronic circuit shuts down completely. In order for the microchip to power down without losing count, each time it powers down, the current count is recorded to EEPROM. EEPROM is volatile memory, so it rated to be written into at least 100,000 times for each byte. Since we’re storing 6 digits, we have the luxury of spreading the 6 digits across 4000 bytes. So a 6 digit number can comfortably be written into EEPROM 66,000,000 times.
-Power is only consumed while refreshing the e-ink display. With a AA battery, the device can refresh approximately 80,000 times. The count is written into memory each time it powers down so the battery can be changed without disrupting the count.
-The momentary push button is rated to for a minimum of 1,000,000 cycles at 50N, which is well above the 2.5N that is required to activate the switch.
-This device is guaranteed to function until the counter reaches 999999. It is also guaranteed to stop functioning once the counter has reached 999999.
