you need to sell the board better.
PRICE IS GREAT

[WTS] Bloody B640 Gaming Mechanical Keyboard - $110

AND THESE SWITCHES ARE AWESOME, BUT NO ONE KNOWS ABOUT THEM
everyone's just gonna think that this is some crappy gaming kb >_>

you gotta think about who you are selling to, we are a bunch of high end mechanical keyboard geeks and your add makes it look you're trying to sell us a black widow from razor.

HaaTa had a slide deck on key sensing mechanisms that included an optical sensor. Let me see if I can dig it up ...

Ah, here we go. Actuation Sensing.
https://drive.google.com/folderview?id=0B4Wyz4bY7XjLOUZGRnhWcldLMUE

From Slide 25 in this deck:

Exotic Switch Types - Optical

Pros:
- Little debouncing
- Conceptually simple
- No corrosion
- Simple sense circuit

Cons
- Requires "debouncing"
- Susceptible to dust/dirt
- Light source has a limited life
- NKRO can be complicated (with encoders)

Of these, I think that the third con, and maybe the second con, are the biggest concerns.

There are some keyboard takeapart photos at https://imgur.com/gallery/9PJ4n.

It looks like the backlight LEDs are separate from the sensing LEDs looking at the PCB design.

This board uses Cherry style, and not Filco/Costar style, stabilizers. Caps Lock appears to be off center and not stabilized. PrtSc/SclLk/Pause are above the num pad. The stock space bar is taller front to back meaning a replacement space bar would leave a gap in the case.

What are these key caps made from?

Ghibli · « **Reply #34 on:** Sun, 09 August 2015, 07:55:25 »

ABS - I've seen the B740 keycaps advertised as "double filled," not sure if this applies to the B640.

Ghibli · « **Reply #35 on:** Mon, 10 August 2015, 09:24:21 »

B640 product page: http://www.bloody.tw/cn/ProductsKEY.php?pid=11
Most of the pics are broken for me.

The English site has details about its close cousin, the B720: http://www.bloody.com/en/productsKEY.php?pid=11&id=65
The few differences when comparing to the B720:

No raised switch mounts/Water Proof
No extra plate separating PCB
1.2mm instead of 1.5
Single instead of multicolor

Two more planned price drops: -$7 at the end of August then -$3 at the end of September finalizing the price. Look forward to it

I just want the keycaps.

If you find a buyer who wants the board without caps, let me know.
