hmm...perhaps will try this soon too Cheesy

btw here is a better picture of the two resistors

Or just do both and you have more brightness than you can handle. o_O

well i had to strip mine down several times before i got it right
just check the keys remember which isnt bright enough then go a little deeper
it will take to get it right
ive mannaged to fix the dull keys around the enter key now
i will take a new picture of my results
oh yeah i allso removed the little resistors and increased the voltage
just hope they dont burn out :/

bottom left alt needs doing and the number 1 and to the left of it allso
notice no dullness around ghjklyuiopvbnm,.

Instead of scratching it the way I've seen it done here ....   What about approaching it like an etching with a dremel and wire wheel or other etching attachment, etching fluid, or just with some coarse sandpaper.  You only need to achieve opaque right?

My thoughts on this are based upon me testing a theory once with a  Logitech PSP hard case.   I scratched it up on some concrete with the challenge of buffing it out to new again.

I failed, but even with the polishing wheel which actually rotated so fast it melted the perspex a little and the area I worked on became smooth but opaque.  opaque would be a good result and is in some fashion what your scrathing is doing.

I've also seen this done at macy's too...  Where people would have custom Christmas ornaments from crystal etched with quite intricate designs and then their design alone lights up when a tree light was placed in the top receptacle.   This is the same thing basically.   These guys could create a snow landscape and where a slope of snowy land was is was just a relief cut area that was opaqued and it was very bright when done.

Judging by how this type of lighting works and can be directed with light pipes and panels and whatnot. etching even with a fluid seems reasonable.

Why etch with scissors?   I hate my lycosa simply because it's just too small and I've been used to a split form ergo keyboard for years now but I would think twice about using it if I could actually see it.  So maybe I'll attempt this approach and keep you posted.

Hello Nice mod. I did it too, but im wondering that with 4.7v now how long the led's will last ?

hi

my lycosa arrived today.
in my opinion the backgroundlight is to dark so i opend the keyboard and search a solution.

first the complete backgroundlight are some smd-leds at the bottom of the board
they are in a transparent plastic panel to diffuse the blue light.
behind every key are "diffusing points" to let the light out on its right place Cheesy
thats the reason why the backgroundlight is darker than the WASD cluster. in this cluster behind every key is a smd led (why not every key equiped with a led and the user can choose which keys will glow Cheesy that would be cool).
so here are a picture of the resistors for the complete backgroundlight.

(http://img508.imageshack.us/img508/317/1011021pw5.th.jpg)
i bypassed this two resistors (R10 R7) to get more voltage (orginal: 3.7V...tuned: 4.7V)
3.7V is optimal for leds without a limiting resistor but i saw that every led has a resistor too Smiley
so i bypassed this two 100ohm resistors (R10) and it works great Cheesy
much better to read the glowing keys with that tuning.

for this mod you will need:

a soldering station whith a small peak
a sharp tweezer to focus the wire
an isolated wire
some soldering tin

then you only have to bridge each resistor itself with the wire..nothing more

if you have any questions pls ask before killing your lightning or board Cheesy

Are you making a bridge over the Resistor, that it is almost, as there wouldn´t be a resistor at all?
Umgehst Du den Widerstand? It looks like a thick copper wire. But not isolated.

yes..bridging the resistors...there are only 10ohm resistors. enough to limit the power for the leds
it is a coated wire but you can use any wire you have

Hmm...tried the resistor bridging but still not as bright as i'd like it to be ><  Actually I though tthat it was a 'safety' feature by Razer - i have been tempering with mice LEDs for a while recently and if you position your LEDs wrongly or too bright, it is extremely glaring to the eye due to the nature of LED lighting.  Albeit the apparent discontentment with dimness, it seems that it was a move to  omit ure keys from competing with your display from waging a light intensity war - well think Sony Ericsson phones with non-adjustably bright (and uneven!?) backlighting. 

I think Razer still managed to pull of a good job on this one as the lighting does not quite 'seep out' in between keys like the Saitek Eclipse nor Reclusa which i feel is negligence/sloppiness on the manufacturer's part.  I have a hunch that Razer anticipated this problem and collaborated with Everglide on the DKTboard to learn from that experience which also exhibits the 'seepage'.

Despite the keyboard being similar in trim level to Powerbook/Macbook Pro notebook keys, they managed to deal with the problem of Razor (non-intended pun here) sharp edges that hook on to your knitted sweater and stuff like that; plus the keys are elevated slightly to allow for improved ergonomics.

heh, so, errr I tried poci's mod (bypassing R7 and R10).

I too was extremely disappointed with the level of brightness of the keys. Unfortunately now they all seem to be out...... on a permenant basis Cheesy

The keyboard itself works fine, the lighting bar works fine if connected to a battery, but doesn't work plugged into the board with the resistors on. The touchpanel works, I can cycle between all off, the wasd cluster on (works) and all off again.

At some point during the mod I skillfully managed to burn the top off Q1. I *think* I did this after it wasn't working when I was having a play, but who knows?  Wink

Obviously all done completely at my own risk.

2 questions:

1) What's the likelyhood of razer selling me a replacement board? (the module, not a whole new keyboard, which I'm sure they'd be happy to sell)
2) Can I wire the led bar into something else to draw power? Can I take it directly from the USB port (with approriate resistor) or am I just asking for trouble?

Thanks

right.....(I knew my elecrtonic engineering degree would come in handy one day)

I guessed that the transistor i massacred could be there to turn the light bar on and off. As I never want to be able to turn the lights off on all the keys I wondered whether i could just bridge this. So, armed with http://www.datasheetcatal...asheets/105/456654_DS.pdf (a datasheet claiming to be for a transistor called 1AM) I shorted the collector and emitter with a pair of pliiers and to my delight found that whatever mode i was in the light bar was lit. So, I attempted to solder a wire across them, which ended up being a dirty big solder blob between the 2.

And thus it works. Interestingly (as you might expect) I can now have the WASD lights on bright at the same time as the rest of the keys on normal, a mod which I'll lay claim to if you don't mind. That is, before I never ever attempt to solder wires onto surface mount components ever again! A picture is attached if anyone is interested
