H120 remote control
bluebrother:
Ah, no. SV1 is the ISP connector for programming the controller. Maybe I should rename that one :)
The remote doesn't have any connectors in the circuit, just pads. That's simply because there is no connector on the cable, and artificially adding one seems a bit over the top to me -- just solder the wires directly to the circuit.

Ah, it makes sense now! With regards to the connector, I'm talking about the plug to go into the player - I'll be working with a severed plug (i.e. wires at one end for the circuit, plug at other end for iRiver). Now I've eliminated SV1 as being part of the remote (!) and as the circuit only addresses some of the wires for an LCD remote (obviously we do not need any of the LCD-related lines), will I be okay connecting my plug to the circuit only, or do you think it is it safer to keep the other wires connected to an LCD remote for completeness?

You don't need additional LCD connections. In fact I cut the connector off of a LCD remote and only wired the needed lines -- works fine for me. As for SV1 (I've renamed it btw) don't forget that you still need to program the controller.

Been a while, but I've finally received the ATMEL chip (actually bought a few in case I can use them in future) and programmer. Am about to order the IR receiver and resistors. The receiver was easy to track down, but resistors seem to be a can of worms - I can filter by resistance but still getting hundreds of results on the component vendor site. Is there a specific type I should be looking for (apart from the actual resistance value)? There also appear to be the classic resistor types and ones that look more like chips. Do the other, non-ohm properties of the resistor make much difference?
I am searching on uk.farnell.com.
Thanks!

No, not really -- the only really important thing is the resistance. I'm usually using resistors with 1% or 5% tolerance and 0.25W (wired) or 100mW (chip) -- it really doesn't matter much for this type of application. That's also the kind of resistors I get at the local store when just asking for resistors. Something like Farnell part number 9341129 or 9333738RL
