sorry, slimfish, I didn’t mean to attribute to you any kind of judgment on the dso… just wanted to know if I was doing it right, my only interest is to make that thing work since I also find it wonderful
anyway here are some other interesting results:
-
the battery goes down also when the dso is connected to an usb port, apparently the ltc4054 doesn’t give enough current… leaving the dso on and connected the battery does completely deplete (screen fades)
-
with the device turned off, the charger seem to manage to give some energy to the battery: after a few minutes the dso is able to turn on again, and when disconnected works correctly, even if with a low battery level
the problem is that it seems it is not able to charge fully (or half-fully) the battery, even leaving it connected for hours
