  • That is not correct, you won’t get a random lower voltage. You are correct that thw PD supply needs to support the voltage but PD always starts with 5V for backwards comparability then digitally its negotiates the PD voltage it wants, if it asks for 12v and its not available it with just stay at 5V. It won’t spit out the closest value unless the device asks for it. Its a very strict and wonderful standard.





  • When cutting aluminum, push very gently. And when the raw material gets too small, don’t try cutting the last little piece. Small working material will increase the chance of accidents. I set my limit around 20 cm.

    This. So much this. Even when cutting wood properly on a mitre be careful with little pieces. You simply cannot control or hold really small pieces. Almost lost some fingers and scaring the hell out of myself making that mistake.
