Strobe the decoder with your own hands

Somewhere I have rolled a full description of the LM567.
if necessary lay out.

who doesn't Have oscila tank here http://xgurux.ucoz.ru/tester.rar

there are interesting prog but no cracks
as will picks open lay out with a Paci.

put capacitor

Better resistor divider or just limiting resistor, the capacitor has resistance and there is no possibility to see a constant component

Hello!
I was thinking about it. In any modern computer has a sound card with multiple channels of audio output. If You have a burning desire to collect AudioStrobe decoder, why not output sound and AudioStrobe signal through separate outputs of the sound card. Enough to dig online and find many sound editors and multi-channel mixers, allowing to create the necessary number of audio tracks. Now, taking any AudioStrobe disk, you can save it as two files, one original and the other with the cut-off frequencies up to 19200 Hz. Then send the audio from these files on two independent channels. To the channel, reproducing the AudioStrobe signal, you can connect a simple device (even simpler than the decoder LM567), consisting of a RF detector diode, a transistor operating in key mode, and several parts (like a simple light setup). By the way, somewhere around the circuit on optocouplers enable you to control the brightness of the LEDs depending on the output level. Who should - share.
Good luck!

2 Guru: datasheet for LM 567 is elementary by Google

2 Sergey Vladimirovich: For playing multichannel audio (more than stereo) and the corresponding desired soft - Winamp is unlikely to pull, especially if split into two files. And run they will have simultaneously. And process each one before playing, i.e. without the possibility of reproducing "real-time", as the same BWGen. And one more restriction: only the computer (in the usual case, the sound can be fed even with the MP3 player)... IMHO, it's not worth it - why so many just turn up, when a simple diagram on the LM567 is quite easy to cope with its task ?

And interference will understand =) Sorry, now with time is tight...

Why to complicate your life? before the LM567 decoders to drive the RF filter on OU.
the program for the calculations of the filters can be contracted here

http://focus.ti.com/lit/sw/slvc003d/slvc003d.zip
the program itself according to the specified parameters considers values, draws graphics and layout.
in General, useful not only for gate decoder

The output of the filter at 567 th, there is no digital signal and a sine wave. The LEDs will now blink soft. IMHO

I thought that there must be two flashes: "soft" sinusoidal "hard" rectangular. Like all mindmachine...

In normal strb-decoder signal points served depending on the disc signal.

You want to say can be written and sine and square wave, and triangular wave visual stimulati? At LMa in the scheme of MDM is said all the time, use a digital output. Is always a square wave.

The diagram LM567 works. At the correct installation and serviceable details.

Keep in mind that an important volume on the output of the sound card.
Because of the narrowness of the features of the filter, the smaller the smaller the amplitude of the input signal. So in the data sheet.
The filter on the frequency of 19200 Hz was configured, to generate a wave (sine wave) in the sound editor Audacity.
Then I picked up the amplitude of the input signal, so that when you turn off Audiostrob'e BWGen when playing presets no flares.
All without an oscilloscope

because I support budget decisions

Тасев Александр · Post by **Тасев Александр** » Fri May 16, 2008 21:51

PS. ie ... if it is wrong to set the volume of the sound will glow constantly

that someone was observed

Zzy ...first, I gathered incorrectly, forgot to connect the resistor (shells) on the leg of the chip. Sitting

and wonder what it is I twist the knob and nothing changes

Z. Z. Z. Y. Wish I can send the mounting. I did on the solderless board. Without soldering.

Nice methodologoy!

It seems that C2 must be in the range of 0,33 - 1,0!.. But not 0,005

Тасев Александр · Post by **Тасев Александр** » Fri May 23, 2008 17:09

All clear...

If C2=0,005, the frequency of 19200 Hz band will be...

48% !!!

C1 is increased to 0.22 microfarads, potentiometer reduced to 1 kω.
In my opinion, is easier to set, more accurately. Honestly, don't even know what was motivated the author of the scheme with 50 ohms

Sustainable operation of the circuit of the decoder LM567 output from the MP3 player was achieved by increasing the output from the player.
20.
Amplifier OPAMP LM324. Included in the scheme non-inverting amplifier.
The signal level at the output of the player 80 mV at full volume without headphones, 70 mV with headphones.
I also reduce the output volume to avoid clipping after amplification.

And as to the ordinary integrated into the obscene cost of the soundcard to connect the LM-567 and headphones. Tried to parallel the glasses off. Can you provide the pattern matching with the values of the parts?

Under the scheme it turns out that only 1 led is the same color you can put? The effect of one is enough or what? And originalnyh mindmachine multiple colors after all?

0,22 UF or 0,022 UF as in the diagram?
