Folks,
as you may have seen in the krytox IC, i will be
stocking some keyboard basics that the community likes to
have, but isn’t quite able to get MOQ together for all the
time. Proceeds from these sales will go towards funding
geekhackers, which, long story short, is a legal way of
funding the site and community (there, i snuck it in again!
concrete example: geekhackers contributed significant funds
to the cherry legends).
anyway, it seems to me that we
have the following two options on USB to ps2 adapters.
First, there is the ID innovations adapter:
http://www.idinnovations.com/usb%20adaptors.html
this is a nice little adapter that works particularly
well with model M controllers. Highlight features are that
it can present itself as a USB to serial adapter, a standard
USB-HID device, or a keyboard emulator that does something
or other. The major plus is that it requests more power on
the bus than most USB to ps2 adapters and auto-reconnects if
the PS2 device is a bit finicky (as some Ms are). Pricing on
these would be about 12-13$ per unit plus ship. The downside
of these is that they don’t have universal compatibility. I
have had reports of incompatibilities with some variations
on the OTD a87 aikon variants, and some weirdo stuff that I
can’t even remember.
There is also the famous “blue
cube” which can be sourced from a number of factories in
china. Lead times on these will probably be longer, as I
will go direct to factory for these. (I source from ID for
the other adapters to take advantage of their firmware).
Blue cubes are physically of lower quality, and not quite as
compatible with Ms, but when the ID adapters fail, a blue
cube almost always works (i have no idea whether the
converse is true). Pricing on this would be similar given
the prices i’ve been seeing, but if I work out enough guanxi
I might be able to get them down a little lower. However, I
do feel quite strongly that the blue cubes universally have
terrible build quality.
Note that I can only afford to
stock one at first due to MOQ. Given that the ID adapters
are much harder to obtain, I am leaning towards those.
However, I am open to suggestions.
