Interesting.

I know that some manufacturers, which include sparkfun, pay a licencing fee. They may be slightly different though, as they do use the "Arduino" name.

I'm sure I read somewhere that ladyada pays a licensing fee or royalty to the Arduino guys for her Boaduino products - but I might be remembering wrong, and not sufficiently motivated to go searching.

Well if the developers get nothing from clones I double my support for buying "official" boards.

1.
Is there any reason why I would want to buy a real arduino rather than a cheaper clone?

To support the original developers - I don't know what kind of licensing deal they have with the companies that sell clones (e.g. seeed studio), but I can imagine they would get more dollars for an official arduino board.

Hmmm...

IPICO improved the passive system by energizing the tags at 125 kHz to allow the tags to start charging at a further distance from the timing mats, and then the tags emit their numeric codes at 6.8 MHz

How does it work?
The system is very simple. The tag contains a microchip and two antenna loops—one to “wake-up” the tag and the other to send its signal. When the tag comes into contact with the antenna mat, it wakes up and starts sending its unique signal again and again to the reader.

Very interesting, thanks again for your help.

Doing some research on those frequencies now...

Well I can post an image of the outside - it just looks like a smooth plastic rectangle, approx 35mm x 25mm x 1.5mm thick.



Nothing visible from the outside - no sign of antenna loops or anything.

The manufacturer describes them as "IPICO dual frequency systems"

Thanks for your help!

OK I've got some RFID tags that I would love to use with a reader.

Problem: I don't know what frequency they work on.

Assuming (at this stage) I can't ask the manufacturer, what can I do to work out what frequency they are?

Thanks

Gee, I don't know . . . “talk,” “walk,” “half,”, “calf”
Maybe we should ask the Colonel?

Just because there are a few examples of silent "L" doesn't mean ALL of them are... :-)

Also I would pronounce the L to some extent in all of those words... they certainly don't sound the same as if the L wasn't there at all, which is the case with the solder/sodder argument.

I put my soldering iron in it's hoLder, not it's hodder.

Anyways I'm happy for everyone to pronounce it however they want, just interested in how the L became silent

Why do people think it's a silent "L" ????

Looking for an Aussie APRS user to collaborate on an amatuer high-altitude balloon project.

I'm trying to avoid the cost and effort of getting the appropriate licence.

Also willing to contribute to hardware costs.

Please get in touch if you are interested or know someone who is!

Thanks

adafruit.net and sparkfun.com have reasonable shipping to australia. Of course the current exchange rate is a killer...

Also, the ability to link to a bank account has been part of PayPal for as long as I can remember....

Linking to bank accounts only made it to paypal australia last year - I guess they probably roll out features to different countries at different times.

Before that, it kind of was a pain to set up a credit card, we don't have the same system of verification - for example we don't link credit cards to physical adresses, so paypal (before there was a paypal.com.au) kind of treated aussies like shady charachters (no convict jokes...)

Anyways in recently paypal have become more world-friendly, and a useful way to conduct business for hobbiests.

I use Pro/E, but anything Pro/E can do Solidworks should be able to do something similar - look for a "fill" or "autofill" command
