IR receiver and transmitter

[cyclops_returns]

I need some help regarding a project. I need to build a project that receives an IR transmission and then just broadcasts it again. You think it's possible. If yes, can you please give me a schematic to that circuit? Any help would be appreciated.

Thanks

Certainly sounds possible, but you don't give enough information - what type of transmission?.

 

[cyclops_returns]

Thanks for that prompt reply. The transmission will be from a tv remote to the TV (or something similar). Basically it will just get the input from a remote and should send it to the paired object. If it's possible, please suggest me a possible schematic

These are readily available for purchase. Do you really need to build it? You're reinventing the wheel.

Yes, easier to buy one, they are freely available - there are plenty of circuits on the net, but they don't tend to be very good.

Things is, it's not a requirement, it's more of a challenge, so I have to build it

Schematic

This circuit comes from a website with bad reputation (non working circuits), but I hope some expert here could help you fixing it

here is one i tested Universal RC5/RC6 IR transmitter/receiver for RC5 & RC6 codes
works off 16F628A
the Tx works as pre-define a code than press to send

You mentioned in that blog that such transmitter/receivers are readily available. I couldn't find one yet. any clues?

p.s.: I'm looking for the possiblity to transfer the IR signal from A/V remote controls to the components installed in a closed rack. should be as simple and as cheap as possible. 1:1 transfer of the picked-up signal

They sell them "IR remote extender" and they are a pretty common catalog item for the appliance stores.

hello..
i'm new to electronic circuits.
i got a project to work on needing a circuit with the ability to record an IR commande from a remote control and re-transmis it when requested to do so..

is it possible to do so or it's easier to modify an enxisting remote control ..

thanks..

do a search on avrfreaks for "twirp".
