@#52935 Oh, I didn't know enough to know what I don't know yet... I didn't think to check the voltages one the intact device, and I don't have it in my hands; I only borrowed it to get the pictures of the missing components. I've ordered a capacitor to specs as explained by Lundin and a 10uh indu... (more) |

It arrived without working. lykketronic acre counter Upon opening its case, I found that the PCB is missing two components, and the area where these components were is scratched, as th... (more) |

A: PCB as a wall of an underwater enclosure Even the best fiberglass and epoxy will suffer under certain conditions. Boat builders routinely test their mixes at varying temperatures and salinity levels. For the best knowledge for your use case, you will want to test the same kind of board under conditions designed to accelerate the deterio... (more) |
