Did I see cloud connected test gear there? That makes bits of me hurt. |

Work has sucked of late and tonight I came home to a furnace not working and I don't have the energy to even try to fix it. On the flip side my EEVBlog BM786 meter came in today. Maybe I can put the meter to work this weekend fixing the furnace. |

At least the weather is getting better? |

with all the talk about the crowbar circuits in this topic, something i've never heard of before, i wonder why don't they implement a battery charging mode then? push the battery mode button = disconnect the crowbar until the battery mode button is pushed again? can just be a regular latching switch and have the power supply detect if it's closed or not so that it knows it's still in battery mode after turning it off then on again? this doesn't sound too hard to implement i think, maybe would add about 5$ in parts, but when talking about 1k$ power supplies, would that hurt too much? |

That's how the crowbar I have here works, anyway. So you can leave the crowbar "off" (effectively) if you don't need the protection. |
