Pack Mule Activation 001 - NO-2590 Kyststiene i Vestfold National Recreation Trail
2026-04-01 · 7 imagesFirst activation on my way to the Pack Mule POTA Award today. 41 contacts in half an hour. There was more to be had, but my mast collapsed in the increasing wind, so I packed up and went home. Europe, Africa and North America in less then brilliant conditions (huge solar event yesterday afternoon). Pretty happy with that!
Testing the LiFePo4 Change Controller
2026-03-30 · 5 imagesGot the LiFePo4 5V, 1A "MPPT" charge controllers from AliExpress. These things are clearly not MPPT, but they seem to work acceptably well. The controller will drop out at about 4.4V, but as long as the voltage stays above that, it will charge even if the solar panel drops down to less then 50mA. It stops cleanly when the battery voltage reaches 3.6V and neither of the two LEDs stay on unless they're powered from the solar panel. Charging at the full 1A did heat it up to just above 70°C though, but I don't think the solar panels I have in mind will ever deliver anything close to 1A!
