yeah there is, but I can't remember what they're called either - try eBay maybe?

2 pin LED cradle?

ummm, sparks! yeah those relays are rated 240v, but I don't have any plans to go near 240v, nor would I recommend it in fact, even the modtronix ppl have got a giant warning message accompanying their boards, that "are" rated for 240v - these are for 12v wall DC, safe to tongue test  ;D

Would I need resistors for the relays?

Nope, I've just finished soldering up a slim board with a 595, 5 relays, and 5 LEDs across the contacts to get a visual on what the relays are doing - they haven't blown yet *lol* if you use resistors the relays won't work, I found that out by accident when I first starting testing relays.

Although its interesting to note that mains is nothing compared to sticking your finger in a ordinary battery powered camera flash. Now *that* hurts.
A 350V capacitor discharging instantly in to your finger.

 ;D ;D ;D  I did that a couple of months ago while pulling apart my old digi camera, if the shock wasn't enough I nearly did it twice as the capacitor on those charge unbelievably fast.

using LED's as the basis of a simulation, you replace the LED's with any relay that's suitable for switching via the low voltage arduino, and the higher voltage light bulb. ie. 5v input to 240v output

No, I don't think so, maybe PM Daniel and ask him, if there is a way to, he'd probably know.

In the UK, sites typically advertise VAT "included", unless your outside the UK, then its deducted from the purchase price.

So not including the GST is probably not an intentional deception, but it could be handled better, for the sake of good customer relations, by including it and then mentioning it only applies if your in the country the tax is applicable.

Or you could easily script it to identify the visitors location and if the IP is in Oz, then include it, if elsewhere, don't.

Try SGBotics in Singapore, I've dealt with Vivan and the service and delivery (to NZ) is superb.

I passed on LB in Oz because the freight price from Oz to Wellington, was more than SG charged for FedEx from Singapore to Wgtn, FedEx takes 3 days, Vivian's totally On2It

Nice one Smiley!

Sparkfun-less don't like people posting problems in their forums when they do happen, and their level of support is a bit hit and miss from my experience.

They are expensive so you'd think they'd have their act together, there are plenty of cheaper alternative suppliers on the web for most of the products I've ever considered buying from them.

But I like the layout of their store and vast selection of products.

Now the suspension will kill us .. what new and exciting Arduino-related products have you got?????

Arduino.com isn't a problem so long as it's not representing itself as Arduino "the open source micro controller" or branding electronic products similar to Arduino as "Arduino".

Arduino.com has few visitors, possibly under a dozen uniques a day, so it would be generating few clicks and it probably costs more for the person to hang onto it then the revenue it might generate from accidental visitors.
 
The domain would only be worth something to the guys at arduino.cc, since only they would be able to use it to sell arduino open source MC's. Anyone else using it for that purpose would likely attract a cease and desist because in that context, an intentional copyright or trademark infringement claim would be hard to defend.  

That's why the boys at freeduino called themselves "freeduino" rather than (arduino.something) "help yourself version".

What were you planning to use it for if it was for sale?

David Cuartielles is the domain registrant, so he "might" be the one to speak with about changing over to SMF.

SMF is an excellent choice, provided you know how to convert yabb flat files over to SMF mySql.

I've run a yabb to SMF script a couple of years ago and it was a complete mess, but it sounds like there are new solutions available?

We wouldn't want any posts lost because a lot of individuals have donated their time and expertise contributing information intended to be used by new or existing members needing assistance. This gold mine of information is the Arduino projects single biggest asset, and it would undermine the efforts of many if it were treated with indifference.

So losing "a few thousand posts" isn't an option, and a change shouldn't be made unless it can be "absolutely guaranteed" that members contributions won't be lost in the process.

You'd need long range rfid readers and they cost a small fortune, and they aren't very long range, I think the max is like 8ft using active tag technology .. passive max'es out at like, 8 inches lol.

It's every developers fantasy to be able to track people in real time as they move from room to room because of the number of home automation possibilities that capability presents.

There's a way to do it using 802.11 but the tags are pretty big and need batteries (active), and those systems aren't cheap either. Plus you need multiple AP's to provide a radar like functionality where locations are "approximated" by signal strength between 3 different reference AP's.  

It's all pretty crustry at the moment. I've seen improvised systems but they all have impracticalities like active tags, multiple APs, dozens of readers or users needing to check in at locations to tell the computer they've moved location.

I saw one the other day and milk bottles have tags and when they are put in the garbage the computer orders more milk. Like, how impractical is that? you get a replacement bottle of milk a day "after" you've run out .. really lame.

Anyway. Part of the fun of developing is having a great idea and then spending 2 years realizing it's not doo'able, or, you need a piece of technology that doesn't presently exist lol.

I can think of a thousand cool things to do with micros but unless you're an expert in every field of technology, it can take a while to discover all the issues of taking a concept to finished product. The thing I like best about this community is its a hive of ideas and new innovation. People here try the craziest things so if you've got an idea throw it around and people might be able to point you in the right direction = )
