I will sell them as a kit. 149:-+shipping(12:-) each including all components and a pre-programmed pic.
There will be no sensor included since many want to buy the sender on its own to attach to their existing 1-wire network.
I will however also sell the different sensors if you are interested.

There is however a small risk that there is something wrong with the pcb since it is my first ever produced. In that case I do not have anything to sell :shock:

Edit: There was a lot more work than I expected so the kit-price is now 199 with an empty pic.

Turned out that my pcb:s had a small fault :cry:

The LED is always on when it was supposed to only blink when sending data.
It is quite easy to fix. One cut of a trace and make a bridge.

You can get them cheap here, http://foogadgets.tictail.com

Any idea if it could be possible (with some modifications) to connect a digital barometric pressure sensor?

Something like this:

Hi niclasf,

Any idea when new stock will arrive? Or did you quit selling them?

Thanks for reading,

Regards,

Marc

Any day now. I have been waiting for 5-6 weeks already. The post service is extra slow now before Christmas I guess.

I post here when they are available again.

Up to 200m. I have not tested it myself.
I have full coverage in my 97m2 apartment.

You might be able to find better numbers if you google FS1000A.

New version available in the first post.
Fixed embarrassing bug introduced in 0.9.4 after testing on the wrong hardware :oops:
I am sorry for the inconvenience.

New fineoffset version available in the first post.
Support for same sensors as the esic_clone.
Fixed problem with showing battery status when using DS18X20/22.
Fixed CRC-calculation so that it also works with Tellstick DUO/NET running beta firmware.

Thanks for the new offset-version.
I find that the battery reporting on the humidity is 50% where as with the mandolyn firmware it always give a number over 100%, which is easy to interpret. Obviously not a humidity report.
I used the Offset version as otherwise the sensor reports as the same ID as another mandolyn I have built.

All really good though, thanks again for this.
Wish I'd had the option of using your printed circuit board you have for sale on your site. All looks great. :)

The reason for having different presentations is that telldusd has a sanitycheck of the humidity data in the fineoffset protocol. If the humidity is over 100% it throws away the package. I was forced to change the span.

If it is from a 1-wire sensor you can always exchange it to another one. If it is from PIR or DHT22 you can now change the sensorID in the EEPROM. Anyway, using fineoffset in stead of mandolyn is of no importance. If any, I'd say fineoffset is a little bit better now when there is a checksum validation at the telldus side.

PM me your address and I will see If I can solve it :wink:

EDIT: impossible to PM me since Telldus forum have not enabled that feature :). Go in to http://foogadgets.tictail.com and contact me there.
