My latest post reveals the connection between Britney Spears and the great physicists of our time, but is totally unrelated to weather stuff.

LOL!  I didn't realize that Britney was at Solvay, though I'm more inclined to believe the Heddy Lamarr story.  And where did you get that photo of my front porch?

Hedy Lamarr was a genius.  Gorgeous didn't hurt her case, either.  And in honour of our great Chip-meister,I dropped a C-note to the Sally Ann today.  I figure anyone who can ask for cash from drunks in a bar deserves some help.

I have now received the boards from the PCB manufacturers, First three built and tested, another 17 ready for anyone that wants them. remember that these have the FTDI USB cable attached, and have the same logging ability as the Davis loggers. They will work with Cumulus and Weather Display, but not with Weatherlink.

cost is less than $70 (and that inculdes postage!)

PM me if you want one

Belfryboy, can you confirm a UK price for those who may be interested, please?

Also, (being a total luddite here) is there a way which your datalogger can work with Sloweather's interface? and be used to give the complete "all in one" type experience without paying the extortionate amount Davis want?? (and if not it's about time you two got together and made a bit of money with each other,LOL).

UKwoody,

this is the all in one package. It is designed to be used instead of the Davis logger and software. I would be happy to share the design files with Sloweather, to improve his simple interface (also it would be easier than me having to ship loggers to the states....).

My appologies, for some strange reason I didnt realise it had the full interface as well, Doh!
So if I bought a Vantage Vue, I could use this and WD straight onto my PC (and thus the web)?

Appologies, I am extremely tired and somewhat slow at the moment!

Cheers
Woody  Ps, just got your messsage, thanks.

Great!. Looks distinctly like my wh3080 is going back, and I'm trying to raise the extra dosh for a Vue, so I'll be in touch.
many thanks!

Here are the design files for anyone that wants to build their own.

In the Zip files are the Gerber files that a PCB manufacturer would require.

I have recently finished the first batch of 10, these are now available for anyone that doesn't want to build their own.

Can't wait for mine to arrive, the WeatherLink is so overpriced which is a shame considering Davis' stations are so good!

Here are pictures of the finished article, the first is the finished PCB without cable

The second is a fully tested unit with USB cable attached. It has been given a sleek domed black epoxy finish.

BTW Max, this is your one on soak test in my VP1 console! On it's way to you today!

 In creating this little beast a few people have found out that unless you are using weather link, you are unable to set the logging interval. this should no longer be a problem. If you use Cumulus the softare does not set the logging interval of the logger, so you have to use a terminal program to set the logger up. If you use Weather display, then just use the Davis datalogger set up facility included.

Thanks to a tame code monkey I now have a setup program that works with my Datalogger clone. It connects via the virtual com port and sends the required commands, with only a little bit of help from the operator. Follow these simple steps.

1. Install the logger in the console as per the Davis instructions. (unplug the mains supply, remove batteries.)
2. Connect the USB logger clone cable to an available USB port and install the drivers from if here promted.
3. Figure out which port your logger is on by following these instructions.
4. extract the LoggerSetup Zip file (attached to the end of this post) to a suitable location and open the WeatherStation Exe file. you should see a panel like this:

5. Move the Com port indicator the port that you found your logger on, and hit the "open" button.
6. In the "Message" box type "TEST"  (IN CAPITALS) and hit send, you may need to do this a few times to wake the console up.  Once you get characters in the "received Messages" box you are ready to set the interval!
7. Using the drop down in the message window hit the "CLRLOG" message and hit send. this will clear any previous daa from the logger.

8. Now set the interval that you require, use the message drop down to select "SETPER" and the parameter drop down to select the value, then hit send. Remember to set this as the same value in Cumulus as well otherwise Cumulus can get upset and hang.

9. Then use the message drop down to select "START" and hit send.

10. Close the Com port, and then the set up program and your logger is running! open Cumulus and away you go.

Hi belfryboy and all,

Received my DIY Logger today and after a little bit of fiddling and working out I've got it running perfectly in Cumulus through VirtualVP to boot! One thing to note is to remember to install the VCP drivers from http://www.ftdichip.com/Drivers/VCP.htm so that your weather software is able to connect.



I am running this through a Windows Home Server unit, but I can also confirm belfryboy's Datalogger works fine on my Mac Pro on OSX 10.7.2 Lion, at least in WeatherSnoop. Again using the drivers off the website above. Obviously you need a PC to run the app to activate the logging if you want it to start saving data (should be possible in a virtual instance of Windows as well).

Extremely happy with this and will be doing some more testing and playing around with the device. Cheers again Rob!

Ta,

Max.

Looks like a nice little app, should make things pretty easy for anyone that doesn't know how to use a terminal program. A couple of things though...

6. In the "Message" box type "TEST"  (IN CAPITALS) and hit send, you may need to do this a few times to wake the console up.  Once you get characters in the "received Messages" box you are ready to set the interval!

You're supposed to send a LF or CR/LF to wake up the serial port, although I suppose just about anything would work.

7. Using the drop down in the message window hit the "CLRLOG" message and hit send. this will clear any previous daa from the logger.

This is redundant, the SETPER command clears the logger memory (that's done so that all data stored in the logger is of the same time interval).


Precious little in your life is yours by right and won without a fight.

C5250,

I usually use the TEST message, just to make sure that it's all working, the LF and CR are sent in all the message anyway. (i sometimes like to use the "LAMPS 1" and "LAMPS 0" to prove I am the master of the console!

I wasn't aware that SETPER also clear the log, thanks!

The cable length is 1.8m and has a USB termination.

Brilliant, have today sold a woodworking machine which will pay for my Vue. I'll order it in a couple of days and email you at same time all being well.

Maybe I missed this, but does this item also store data like the Davis version for a period of time in case WD gets hung or is shut down?

I currently run sloweather's cable which works fine... Also is this cable capable of doing software updates to the console should Davis release one in the future?

Yep. That's right, it has the same storage capacity as the Davis logger. I can't be certain that it does the firmware upgrade, since I have a VP1 that does not support cable uploads, but if SloWeather's cable can do it, then I don't see any problems, perhaps anyone that receives one of my cables can give it a go and report back?
