Electronics Anyone ever seen an IrDA module for the mobo port?

Most mobos have an IrDA header i'm very keen to start using mine!

I want to make a IrDA module anyone have/seen a good guide or scheme?

Scouring the web I only found one link while its good i'm not sure I can trust it.

I found the part at Farnell...
code 942534 Ir Transeiver HSDL-1100 £3.84

Pretty cheap all in might give it a go.

Actually that looks a lot more complex than the kit I bought from a store here called Jaycar.... I'll see if I can dig up the schematics for you and post them tomorrow.

 

cheers mate, love to see the scheme.

This design is only looks complex because it uses pro-method of decoupling capacitors. It not that complex a PCB.

Its only £1 worth of resistors and caps. I'm gonna make 3 of em!

just found this only a couple of caps on that board does look simple

That's the kit I got... there's a couple of resistors on the other side of the board though.

 

therider,

do you actually have a schematic or just a pic of the module?

i'd really like to get hold of a actual schematic if you got one.

 

I'm drawing a schematic at the moment I cant finish it for a couple of days untill my IR transceivers arrive from Farnell.

Rest assured when I put it together i'll do, scheme, pcb tracks, instructions, part list etc...

I'm trying to simplify the design, cut out a few caps. All waiting on farnell delivery!!!

Dont bother with it, IrDA only works with certain remote controllers so that means you wont be able to use your TV remote or your All in 1 controller. they work on different frequencies to "normal" IR devices.

Check this link

 

I just wanted to uplink my mobile with it and i'm pretty sure it will work for that.

It works very well with my Mobile (Nokia 8250). But damnit... I forgot to grab the schematics from Home (I'm at work at the moment).... d'oh.... tomorrow!

 

Hopefully my IR transivers will arrive tommorow. When I put it together and it works (hopefully) i'll post my scheme and pcb layout. Interesting to compare them to Jaycar's.

And total parts is running @ only £5

very nice idea...might have to give it a try???

 

therider,

as soon as you finish the schematic, i'd really like to get a hold of it. thanks alot.

 

IR bits arrived today i'm off to mappers to get the rest of the stuff.

:Exited:

Full schematic by tonight!

Etched my first PCB quite proud of it.

IrDA MOD IN PROGRESS!

Okay, I've drawn up the schematics... just looking for a host to upload them to.

 

Okay... here's the schematic... sorry if the image takes a while to load... don't know how good that provider is. C1 is supposed to be polarised too.

 

I just threw it together...



Look at the state of that soldering.
1) Couldnt be bother to put my fine tip on 2) Had to bridge holes in the tracks from drilling 3) Next time make the tracks wider!!!



Cant test it yet I forgot to get the blody 0.01uF capacitors!!!

Do you know the part number of the IR component. Thats scheme is much simpler. It probly uses a different IR Tx/Rx to mine.

the rider,

does it work? have you tested it with anything? would love to know.

jazzXP,

let me get this straight,

R1 = 13ohm
R2 = 47ohm
or are those k's?
and is the IR unit a typical HSDL-1100?
