While working on the programming to the microprocessor, my friend accidently turned the voltage knob on the power source connected to the evaluation board. The voltage rose from 5 to 10 V, and before I could shut off the power and remove him from the power source the damage was already done. I felt a subtle smell of burned plastics, and the card was dead. Luckily, little real damage was done to the project in whole. We had ordered two cards for exactly this purpose, so all I had to do was to disconnect the faulty board, get a new one and plug it in. All the software resides in the main computer, so after downloading the code it worked again. The card costed 1250 SEK (around 140 €)
