I should add: Think, Reinoud, and consider, lest you and your inferior work
not be taken seriously, and even ignored. The hardware here is quite ahead
of your's in every way, and even at that you had to derive the vast amount
of what you have now done from this list and members on it. If not for the
list and the input you received, you wuld still believe such foolishness as
that a finger plate is not necessary, and many more mistakes and wrong
assumptions and faulty designs. Is this how you waste your engineering
resources and your staff and supporters? I have hundreds of people here for
a study of many aspects, and work is proceeding even as we interact.
Personally, not having been an industry man, I would rather build something
which exceeds specs, test it and get it into the hands of the people who
need it. That is how it has been for biomedical all of these years for me
here. If studies are what helps, then they will be done with precision,
very large samples of all sorts, and by that time hopefully you will have
either grown up a bit, or perhaps you might agree to work at that which you
are more suited.

If you are on the list, and if you deliberately take peoples' ideas which
are intended as open source, but try to represent them as your own, then you
are answerable to not only me who ask, but to the list. Besides, I cannot
read your blog nor see your pretty pictures. How many foolish questions and
more so observations and wrong assumptions of your's have been corrected by
people on the list, and you have the rudeness to write and say as you do?
If it were not for vast input from this list, and from a few members in
particular, you would have nothing but a convoluted door buzzer, and that's
for real.

1) Not definitive, depends on further testing, but so far around 0.6mm pins
seem to work best.
2) Published before here and on the weblog, see no value in repeating it.

Reinoud: if I may ask, I have two questions:to view the list archives, go to:
1. What is the diameter of the tactual pin felt by the user?
2. What is the distance between the centers of each of these pins both
vertically and horizontally?
Thanks,

Subject: [optacon-l] Display unit prices
Choosing between display frame options requires not only specifications or
descriptions, cost can be just as important. I have been calculating costs
for building single handmade units complete with embedded controller and
USB
interface. Such display units can be connected to a USB-equipped PC,
mobile
phone or specific controller (like a handheld camera unit).
Details can be found below, but here are nominal prices:
- 'Standard' Optacon-compatible layout, 6x24, 144 pins, up to 300Hz
vibration: GBP 1650
- 'Symmetric' (staggered) layout version, otherwise the same as Standard
Optacon-compatible: GBP 1650
- 'Mobile' version, 72 pins, up to 150Hz vibration: GBP 1090
- 'Flat3' 3-fingertip wide flat version, 24x10, 240 pins, up to 150Hz
vibration: GBP 1800 (up to 300Hz: GBP 1850)
- 'Flat2' 2-fingertip wide flat version, 16x10, 160 pins, up to 150Hz
vibration: GBP 1400 (up to 300Hz: GBP 1440)
Investing in such an early unit would enable anyone to support development
and set up local tests (or start software/application development).
Prices per unit may be lower when produced in higher numbers, and price
differences between frame types will become more obvious in that case.
Whether it makes sense to set up production like that remains to be seen
though, it would probably take something like 25+ units to be worthwile.
Right now I doubt a crowdfunding campaign would get that much support, and
single units like the ones listed above would have to be tested first
anyway.
Which types of controllers/drivers will become available for the displays
is
not certain yet, but a generic (PC/Mac/Linux) 'screen scanner' system will
be available soon. Access to Android and iPhone/iOS screens will likely be
possible too, though there may be limitations with these mobile systems.
If
you have any PC available you may be able to install the screen scanner
system yourself, the software will be made available free of charge.
Otherwise I will be happy build a dedicated system at nominal cost (say
GBP
400). The screen scanner may well be implemented as an embedded unit later
on.
A few notes, of interest mostly if you actually wish to obtain one of
these
early units:
- prices are for manually built display units with USB interface, in a
simple enclosure, incl. power supply, excl. power lead
- these early units are considered custom devices, don't hesitate to ask
for
custom configurations and lead times
- prices are VAT-free right now, excl. shipping from the UK, any import
duties etc. (shipping will be at actual cost)
- contact me for details and arrangements
- prices are subject to change
Any support will be much appreciated, I won't be able to keep up
development
at this rate indefinitely without support!
