Resistor replacement for poker 2
« on: Mon, 02 February 2015, 20:40:55 »
I accidently clipped one of the resistor on my poker 2 and in need of a replacement because the key doesnt register.

can someone point me to one on ebay?

Resistor or diode? Resistor is for LEDs, so your LED doesn't work? Or your switch doesn't work?

LED works but the switch doesnt

this is the part that I damaged

Resistors are still used in a keyboard matrix as it allows NKRO on a hardware level. So they aren't just for LEDs.

To the OP, GON sells the diodes you are looking for. Those are SMD diodes so it's a bit more annoying to solder onto the pcb compared to through hole components (e.g. the switches, LEDs). So if you are a bit inexperienced with soldering SMD components I suggest getting someone else to do it or proceed with extreme caution as I feel that it's much easier to ruin a PCB by trying to solder on SMD parts if you don't have much experience with soldering.

Hey thanks a lot man, it looked like a resistor to me. Hopefully Im able to do it, never soldered an SMD diode before.

No worries :) If you're going to attempt to do it yourself here's a video that I found very helpful

Nope. I'm pretty sure this was just a typo and you meant to say "diodes". Anyway, great posts and that should get the OP's board up and running again.

Just to note: Diodes have polarity and need to be installed the correct way round in order to work (the stripe or line is always closest to the minus side / cathode), so just make sure to install it the same round as the original was. If it's off the board already and you can't remember which way it was, the ones for the other switches in similar positions should be the same way round so you can use them as a reference. Resistors can be installed either way round.
Buying more keycaps,
it really hacks my wallet,
but I must have them.

Oh yeah nice catch  :-[

I saw the picture and knew they were diodes but for some reason I kept referring to them as resistors, thanks for the correction  :thumb: didn't want to be responsible for further screwing up his PCB :p

You don't have to get it from GON, since shipping will take forever.
Just look it on Mouser or Digi-key.

You can buy some switches to go with them if you want to.

Tried looking it up on Mouser and Digi-Key and I dont know the part number.

Look for 1N4148. They're a high speed diode. Comes in a few package options, but either the "surface mount" round package or the through hole package with pins will work fine.

Is this the correct one?
