Davis VP2 WX running on battery

The cost from Davis for the “Front Cover Shelter Housing” http://www.davisnet.com/weather/products/weather_product.asp?pnum=07345.114 is only about $30.
I couldn’t find the cost of just the circuit board. Will they do just the board?
Niko, my station is too far from power to use Stuart’s suggestion. But thanks. I wasn’t sure where to put my question, so it’s OK with me to move it.

I’m seriously thinking about trying Stuart’s suggestion to put a permanent power supply to the ISS. I just need to know a bit of info first.

The intention is to get another power adapter for the ISS and cut the lead some 2" from the end where it plugs into the ISS board… then add additional cable so that it will reach from my garden shed power socket to the ISS, securing said cable to a straining wire between the eaves below the ISS and the garden shed.

That’s the plan… but will there be any drop in DC power over say a 40’ run?.. I hope not because it is a lot cheaper way of doing it, and I can dispense with the worry of batteries running out.

Your thoughts on this idea will be appreciated.

The current draw on the ISS must be fairly small if it can run so long on battery power or
the super cap, so IR drop across a 40’ cable, assuming you use a reasonable gauge of
wire, should be minimal. I don’t think you would need to worry about it.

Agreed. The adaptor voltage is higher than the minumum needed too, so even if you used something like 22 gauge/phone/cat5 I think it would be OK.

Thank you, Keith and niko… that’s a weight off my mind!

I have to wait until my brother has time to do it, but I’ll let you all know how it worked out.

If you are in the US they’ll exchange it, for a fee of course. As aardvark posted, if you ask nicely they may send you the replacement first and then credit you the difference between the board and exchange price.

Talked to Davis this afternoon and ordered the circuit board (w/ enclosure) for $82 and will have to send back my old unit. I asked about the solar panel and they said that my voltage was good (2.9) and didn’t need to replace the door of the enclosure.

This is just an update on what was a problem with my ISS… basically, connecting a power supply to the circuit board has solved it!

I ordered a Universal Power Adaptor from Amazon for

Thanks for the update, John. I’m glad it all worked out. :smiley:
