The device is light and sound stimulation. Design points

as I have solved adapter usb-com, it is possible to use adapter data cable here is the information we need the simplest USB color music http://electro.tora.ru/index2.html and to make it even easier - we only need 2 diodes of the three on the scheme - on RTS, DTR.

yet a question arose whether pull the com port pieces 6-8 LEDs?
the link is dead already, so I give another for the same material

IMHO, not pull

better not to risk and to put additional transistors in the key connection and a separate power supply. I have 4 LEDs, though each channel in parallel hung, well, nothing worked

(however, decided not to tempt fate - was removed, leaving one led on)
-------------------
in General, this turns out to 6 LEDs in parallel - somewhere 0.18 A=0.03*6 and com port i.e. 0.05 And two more pull, and 6 are unlikely. Got the idea from the shift register to indulge

to connect colorful sveiki...

thanks for the reply, I still use 2 LEDs for the eyes
another question - should you touch the sliders or not, responsible for what the divider signal?
how to determine the optimal value? on the eye?
maybe we should add a switch frequency audiostrobe,
because the disks Patrushev and classic strobe frequency is slightly different...

Fiction.

Yes, not exactly fiction, on the forum wrote that the "loudness" signal for audiostrobe on the disks is low, but I have to check on my disks Patrushev.
And about programs - the top slider boosts the input signal when the input signal level is not enough, usually do not touch it, the second is the level of the signal in % of the maximum, which triggered the inclusion of LEDs, usually in the middle of the optimum level.

well, today or tomorrow will test, report, give the topic!

the volume control signal to audiostrobe on the disks is low

and where the sound level and frequency?

Звяга · Post by **Звяга** » Fri Jan 07, 2011 21:02

and who is about the frequency of something in this line said? the standard frequency is 19200 Hz, and the level is low, it is not at any volume they're positive for this signal.

post your points as promised, though late,
glasses used 2 red 5mm bright led, the brightness of which was redundant, I thought it would be better to use more LEDs for a more complete coverage of the field of view,
just in case, I glued foil glass points to the reflection of the flares fell on the periphery of vision.
to replace the diodes on the other colors I decided not to solder the LEDs and use the connectors like on the coolers.
to connect to the computer used was a usb-com adapter
voltage but overall it was 9.3 volts. LEDs
supplied 2.2 kω resistance, +shells 4.7 kω to adjust the brightness.

great you did it

and I have yet to mind the glasses and brought from the city to find cheaper glasses to not too bad they were drilling.

one diode on the eyes a little. Tomorrow will record your video

ECCO
to each his own, there dimych even put the potentiometer, because he really shines. Of course, the brightness of the LEDs depends on their color.

another question arose, will pull to see if the com port pieces 6-8 LEDs?

or maybe just simply to count?
com port gives you 25 mA, while it is protected from short-circuit, so restricted with the current (ruin will not work). Super bright led consumes 20mA.
current = voltage / resistance.
that is, consider

not that bright Yes, but there is the fact that the diodes are located around the pupil, and one can be placed only in the center, but it is not Gud, apparently
