Ezért ne rakd sose a botmixer adaptert mosogatógépbe

I bought one and opened up, to save you from doing that :D.

QTableView scrollToBottom anomaly 

Never call QTableView::scrolltoBottom from slots connected to the model's rowsInserted signal because as the rows added they will start to appear partially:



Connect your slots to the QTableView::verticalScrollBar's rangeChanged signal

Dewalt N599252 teardown 

Got a broken Dewalt DCG414 angle grinder to look for the issue.

It has a 54V BLDC motor with builtin ESC mfr P/N: N599252.
The only option is to buy the ESC with the motor and the trigger circuit for ~180 GBP...

I removed the ESC from the motor. The ESC is potted with some PUR resin, so I started to carefully remove it.

It turned out that the low side MOSFETs were blown.
