PID based thermostat built using the Flash Destroyer module

Tuesday, December 31st, 2013

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....

Free PCB Sunday Flash_Destroyer build

Monday, June 14th, 2010

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...

Flash Destroyer wrap up

Thursday, June 10th, 2010

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...

Flash Destroyer: Dead at 11.49 million

Monday, June 7th, 2010

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...

Free PCB Sunday: Flash Destroyer

Sunday, June 6th, 2010

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...

Flash Destroyer firmware update

Thursday, June 3rd, 2010

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...

Flash Destroyer passes 6 million writes

Wednesday, June 2nd, 2010

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...

Flash Destroyer passes 2 million writes

Friday, May 28th, 2010

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...

Flash Destroyer approaching 1 million writes

Wednesday, May 26th, 2010

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...

Prototype: Flash_Destroyer

Tuesday, May 25th, 2010

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...
