Burning 600 mA in the test leads at 2.8 A , need 8.6 V to get 8 V at load. I'll need to invest in thicker copper...

    I just found out that I have 3 replacement FETs left. I ordered 5, used (and destroyed) 1, mailed one to peteroakes.
    Maybe a good time to implement that overload function that I've been procrastinating on since forever ...

    :) yes it is easy to destroy them with over power without even realizing it at the time, unless were tracking the temperature and power dissipation and as you say have limits in place to protect the system

    Oh, thanks for sending an extra to me, I will be building up a power supply version very soon and it will come in handy

    It happened in a god second. That's why the over-temperature protection (that's implemented but too slow to cover the funny experiment I did)  didn't catch it.

    not a god second. A good second.
