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....Tags: DIY, PID, thermostat

IPenguin got a free Flash Destroyer PCB on Free PCB Sunday. He used sockets with the 7-segement displays so different colors can be swapped in later. There's a build log with lots of photos in the forum. On May 30, 2010, I saw the Free PCB Sunday: Flash_Destroyer blog pop...Tags: build log, giveaway, pcb

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...Tags: eeprom, failure analysis, wrap up

Some time between 8:00 and 9:00 UTC the Flash Destroyer reached 11.49 million write cycles and detected a verify error. The final count is 11,494,06X, the last digit is X because we won't know what it is until we read it from the PIC over USB. The destruction started at...Tags: destruction, eeprom, endurance

We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. PCBs are made through Seeed Studio's Fusion board service. This week...Tags: Flash Destroyer, giveaway, pcb

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...Tags: 10million, eeprom, firmware, unsigned long

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...Tags: 6 million, eeprom, endurance

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...Tags: 2 million, eeprom, endurance

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...Tags: eeprom, giveaway, million writes

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...Tags: 7-segment, eeprom, flash, kit, tester
