Hi,

I'm thinking of buying some IR Emitter/IR Blaster thingamehoochies, and importing them in from overseas. The cheapest I can find here in NZ are these (http://www.tradetech.co.nz/shop/Outdoor+Aerials+%26+Accessories/Remote+Extenders/IRSEND70.html) which are $15 plus GST plus shipping...

I reckon I can get packs of 4 of these puppies (http://www.smarthome.com/8170s.html) for about $40, so that's work out about $10 per emitter, maybe less. As I only need 1 I'll have some spares. If anyone is looking to get some of these then I'd be happy to split the shipping and share the happiness around.

If you are keen, let me know before, say, Monday 7 July.

Cheers,

   Jon

All these blasters/emitters are are an infrared led such as this 5mm Infrared Transmitting LED   attached to a TS plug.

The current limiting resistor is in the hub or sending device. These are all I use at home on my IR hub.

Receiver units are slightly more complex because the receiver LED demodulates the signal from the carrier so the unit has to add circuitry such as a 555 timer to add a carrier back before sending on.

Please excuse my ignorance. I have this 3.5mm jack on my wall plate which I can plug in an IR emitter. I bought one from eastern hifi for 30 bucks and it works OK.

But, I anticipate that I will need more. 

So, using this jaycar led, how do I turn this into an emitter with 3.5mm plug?   I looked up TS plug on the jaycar site but found nothing.

I assume I need the following: 3.5mm plug, 2 wire lead , and the IR emitter. Then, I can just solder these together and should work OK. does polarity matter?

Yes, by TS (Tip/sleeve) I mean a 3.5mm mono plug. Connect the anode (long arm) of the LED to the tip of the mono plug and the cathode to the sleeve.

Brilliant, this sounds just perfect! Thanks for the help. I need about 6 of these things, so this will save me my next petrol fill-up and be fun to boot.
