Title: Ardo Electric Cooker odd behaviour
Post by: Hydrawerk on July 06, 2013, 04:01:40 pm
Hacker vs. Ardo Electric cooker - very odd behaviour (https://www.youtube.com/watch?v=GUkuiPb98eA#)
The firmware is not well implemented. I have never seen this on similar digital household product (like microwave oven or so.)
This Ardo cooker is type 6PA40 EE.

Code monkey - I need the code to work so we can ship... I need more time to get the bugs out......No time, we ship next week and the code needs to be done by tomorrow morning..... What about bugs?.... As long as the clock runs and the timer works who cares, get on it code monkey!...... I am going to need a case of red bull and a case of coffee then

Reverse engineer the eeprom to fix multi key press issue and send the patch back to Ardo. Along with the oven ;D

Well, the heating elements are OK.  ;D ;D The whole digital timer can be eliminated when necessary... The oven has an oldschool mechanical turnable switch, too.  :)

My guess is they multiplex the buttons with the VFD and heater control, I wonder why.

Saves pins on the micro, they probably did not want to step up to a bigger more expensive ASIC as then they would have to pay more for both silicon and the high voltage processing steps ( VFD needs a 30V process to drive it) and would have a lot of unused expensive blocks unused.

The worst problem is that such faults occasionally cause the oven to latch on full power and burn the kitchen down. It happens when the designers put the temperature control loop in the digital side instead of having an analog or electromechanical thermostat.

Fortunately, my oven is semi-mechanical. The microprocessor can only turn off the heating element, when somebody turns it on. There is a true mechanical thermostat. The oven is not smart, it only has  a timer.

Why does the autofocus motor on your camera sound like its from the 1950's

DSLR with built in microphone does that. You need an external microphone to get the noise down.

Quite a cacophony of cool noises.

I hear a dance remix in the near future.  :scared:
