Sorry, i can not provide any link, it is hardly to find that type of diode :(

Search for EDSN-1LA3 / EDEN-1LA3 for 1W star from edison-opto. The one i used is a cheap chinese one. Take a look at osram SFH4231, it is even more powerfull but will be hard to find collimator for this.

I cannot find the high power 940 nm led in any store, please help (only the little ones or 850nm).

if you can post a link it would be great.

Thanks,

Guy.

Aquatarkus, can you show it? Some pictures? What type of diode did you used, 850nm or 940nm? Or normal 20mA?

And yeah, sending all codes (for EU) takes about 50 seconds. But most of tv’s are shutting down in up to 15 seconds (15 secs takes to shutdown LCD LG).

Well, I’ve just finished it. At first I couldn’t find IRF7455 so I put in IRF7403. It didn’t work, since its the gate threshold voltage is over 4V and mosfet didn’t turn on.

However today I found required transistor, and now everything seems to work ok, at least at home. The only drawback is noticeable delay before turning off TV because there are too many possible codes and MCU has to go over all the options.

Anyway, tomorrow is the day of field tests :)

If “-” means unprogrammed, then they are set ok. If you bought new uC then only thing you must to do is disable CKDIV8.

And take a look here, very helpful avr calculator http://palmavr.sourceforge.net/cgi-bin/fc.cgi

Thank you, got corrected archive with sources.
I’ve just started to construct my own flashlight. How did you set the fuse bits of ATtiny85? Please look if the following settings is ok and correct them if something’s wrong.

Guy, search in online stores, ebay. And program it with AVR ISP programmer.

Aquatarkus, sorry for that, check now again, C sources are included now.

Could not find the C sources in the archive… :(
Afraid to try without them. Should anything go wrong, I’ll be completely astray.

Could you post where can we get the parts and how to program the chip? Thanks.
