RommudohI fixed the mistake with the <a href="https://social.tchncs.de/tags/MOSFET" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MOSFET</a> and didn't even have to turn it on its back. I lost one in the attempt to bend the legs. Now the power gets cut when it's over 5.53 Volts. Both LEDs turn off then, but fixing that would require cutting traces underneath the <a href="https://social.tchncs.de/tags/comparator" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#comparator</a>, which I don't want to unsolder again.

Szymon BęczkowskiDo any of you have a SMU that can reach 1kV level? I’d like to do a simple (remote) experiment but my SMUs only reach 210V. Keithley 2410, 2470 or 2657 models would be ideal.
