Did you find a US source for the LCJ unit?
No. However, you can get in touch with LCJ and they can ship you a wired Davis-compatible unit. Apparently the only Davis-compatible version readily available in the US is the solar powered unit. The problem is that they want a good bit more for the wired version than what you can get the solar/battery powered version for. Doesn't make sense to me.
Ultimately it doesn't matter though. We were able to play with a serial output unit and it did not perform well in heavy rain.
Any updates on this project? I would like to move from the Davis cups anemometer, and have looked into a Young, or going with a sonic one...but not the Davis model...
No real updates. We have thirteen stations using the beta boards. Currently we're aware of two problems with the firmware and one problem with the board:
1) millis overflow is not handled well - the problem is in a M0 timer library that we just haven't had time to dig into
2) a wind spike is produced upon powering on the board - we need to disable the output for a few seconds to allow the board to stabilize before sending data to the ISS
3) In a power outage event, 5V DC flows from the ISS to the board draining the ISS - just needs a diode
At the moment we're undecided on whether to create another iteration of the board or just fix the boards we already have. If we do create another iteration of the board we'd likely aim to make it more compact by ditching the analog voltage input and IO RJ45 port.
Whatever we do, it won't be until spring. What we have in place now is technically working and none of us like cold weather.
LCJ don't works well.
I have to agree. I think the appeal of them has to be with the size and ruggedness. The sensors are well shielded as opposed to something like a Vaisala WXT or Young 86000/91000. The transducers on the Young and Vaisala units are delicate.
