PID based thermostat built using the Flash Destroyer module

jeanmarc78 posted his PID based thermostat built using the Flash Destroyer module in the forum: After trying a few commercial thermostats for my central heating (hot water), i was not really satisfied. They don’t provide a smooth regulation. Then i decided to build my own one reusing my flash destroyer hardware board.  

Flash Destroyer wrap up

11,494,069 is the final write-verify cycle count for the Flash Destroyer. Since the flash destruction ended on Tuesday, we’ve been playing with the EEPROM to understand how the failure behaves. We found a ticking data time bomb.  Broken bits can linger at a recently written value for seconds before corrupting. Certain writes initially appear successful, which […]

Flash Destroyer firmware update

The Flash Destroyer was offline briefly for a firmware update (live stream here). In anticipation of rolling over to 10 million write-verify cycles, we’ve added a decimal point that shows the millions place. When it hits 10 million the least significant digit (the 1s) will be dropped, and the decimal point will move one to […]

Flash Destroyer passes 6 million writes

James managed to catch a screenshot of the Flash Destroyer as it hit 6,000,000, thanks James! The EEPROM is specified for 1 million writes at the voltage and temperature extremes listed in the datasheet. Running at room temperature, this chip might surpass 10 million write cycles. Or not. Stay tuned and find out. Submit your […]

Flash Destroyer passes 2 million writes

Some time in the last few hours the Flash Destroyer passed 2 million write-verify cycles. jnd points to Microchip application notes 01019A [PDF!] and 00537 [PDF!] that explain the EEPROM endurance characterization process. The higher the temperature, the worse the endurance will be. Generally, and approximately, a device which fails at 10 million cycles at […]

Flash Destroyer approaching 1 million writes

The Flash Destroyer, our new EEPROM tester, is going to reach the first million write cycles in the next few hours (see a live stream here). Can you guess what the final write count will be when the EEPROM dies? We’ll give a couple unpublished Dangerous Prototypes PCBs to the three closest guesses. You can […]

Prototype: Flash_Destroyer

The most recent documentation is now on the wiki EEPROMs, such as flash memory, store data in electronic devices like cell phones, smart cards, SD cards, and solid-state drives. This type of memory can only endure a limited number of writes, it will eventually wear out and it won’t store new data. The Flash Destroyer […]
