Vantage Vue Techie questions
« on: August 15, 2019, 02:09:05 PM »
Hi.  Been away for a while due to divorce and all that ;-)
Finally got my old Vue out of storage and it dores work but...
Mine is an old series F.  I'm getting the typical data loss halfway through the night and low battery warning.
However and here is the qustion
1) If the Supercap has gone. How does it work? ie solar panel charges cap during day. cap runs then dies and theorectically would somehow switch over to CR123 battery.  But it doesnt.  So if I were to rteplace the solar feed with say (for example) a 3v regulated PSU, would that stop the data loss?  Presumably there is a diode somewhere that acknowleges some kind of V drop, so could that not be faulty instead?
2) Ok getting a bit silly here I know but.. The anemometer is a cartridge. If I would to put it into a seperate box, with the Hum senor and legthen the ribbon cable, why would that not work?

Kind regards
Woody

1. In practice, bad supercap = new harness needed. Not much more to get a a new Vue ISS;

2. The Vue anemometer is not just 'a cartridge' and can't in any meaningful way be separated from the Vue ISS. The cartridge refers to the spindle & bearings for the shaft;

Johnd,
Why can't you just replace the super capacitor? Seems to me like a less than $10 (including shipping) and a soldering iron and you are in business.

Not sure exactly which 2.7V - 10F would work but it probably doesn't matter much.

Remember the Vue PCBA is potted, so replacing the supercap is not easily practicable. (It is kind of hackable but most users wouldn't want to.)

Hmmm...didn't know that. Yep that does present a bit more work to cut the epoxy or silicone potting and then resealing. Certainly doable but I agree it isn't something a lot of people would attempt.
