I've had quite a few 'experiences' during my first 2 years:
- Touched both poles on a AC Plug while plugging it in.
- Nearly had fingers removed by wheel spokes when I bumped into the joystick of an enabled robot.
- Mis-Programmed and Autonomous routine, causing the machine (aimed @ head) to shoot discs and balls at me at full speed (Did this more than once
)
- Have had electronic components explode in my face while working on them.
- Had a pressured air canister fail in front of me due to worn threads.
- Probably others I'm forgetting.
Not having anyone to teach me electronics or software design, I ran into more than a few 'accidents' along the way. Now a 4 year veteran, I try to use all of these to teach new electrical guys to avoid the pitfalls before they happen.
