Title: Poker LED Mod
Post by: jrockroll on Mon, 23 April 2012, 23:01:02

Does anyone know how to put some leds on poker? Or is that even possible?

Yeah it should be possible. There are leads for LEDs on the PCB but I have never tried to solder new ones on.

Wouldn't they only work when the other leds were turned on? like for example when you activate the esc key toggle?

I saw some pic. who's mod. poker. but you can not dim. the led like race do. It's just turn on and off and always bright.

Where'd you get the case?

there are tinned holes for through hole leds, but no wiring on the board. powering the stuffed leds would require either hand wiring or another pcb sitting below the poker pcb

That looks amazing. So jelly right now.

I've been thinking about doing WASD and connecting it to the esc lock. Doing the whole thing seems like too much work, and too messy. Though some wire mess could be avoided if you got led with extra long legs and ran them in series. I made led sign like that power over usb, so it should be the same in theory.

You could fit a headerless teensy, or single use (deadbug/freewire) ATMEGA16832TQFP flashed with some basic PWM instructions and a simple toggle button to cycle brightness modes. couple decoupling capacitors,16mhz xtal, and 60+ LEDs w/ 60+ 470ohm Resistors and you should be good (although, I would bring in a secondary power supply to the ATMEGA, but you could possibly piggyback. Although you might need to provide a secondary 5v-3.3v regulator and power from the usb/ps2 port or the LEDs as well because I wouldn't trust the ATMEGA168's internal regulator for that many LEDs. Also, might want to break the LEDs into Multiple Parallel Matrices rather than just have them all in series on one GPIO (8x8?).

To make it a little more flexible though, you could use an ATMEGA42U4 and latch on to the usb header in the keyboard and have an application on your desktop to adjust the brightness via a serial(usb-serial, not actual 9-Pin DSUB COM) interface.....  (This is all on the assumption that the previous mention of the LED holes without traces is correct, since I can not see the PCB, I can't be certain.)

And obviously, it also is completely dependent on what type of LEDS you choose and their power requirements (12v, 5v, 3.3v, 1.8v). So the 470ohm rating is just with the assumption average power requirements is roughly 160mW, or 410ohm

Can someone post a pic of How they wired their LEDs for the poker?

Like a pic of the pub all wired up, I want to see how other people went about it

All we need to really see is the PCB, with or without LEDs, then you could pretty much figure it out from there. Can anyone take theirs apart and post some pics...

EDIT: Nevermind, here are some. From this site! Search is your friend.

EDIT2: No Traces. Which will tell you, wire in groups. I wouldn't have an always on setup if it were me. A simple MCU would be the much better and proper route. Or, hell, you don't even have to use an MCU! Could could get by with a 7805 (if going from 12v to 5v), LM317, DPDT switch (or varistor if you can find one small enough), and misc other parts. You could wire each LED to the switch so that the actuation of each switch opens the circuit and causes the LED to turn off when key is depressed.
