Hi,
I have read some times on this forum.
Now I need help.
I have laser show from shinp, and I want modding into green, violet laser.
It wil combine into licht blue.
But it has one laser driver for green laser.
I can just add violet laser with laser mirror, but when no music comes then only green laser will off. (for safety)
I have build driver (see picture below), but has no ttl function.
How can I add this?
This circuit comes from zet.biz
It's usefull and works. (note R1 rate must be calculated by LD, R2 too)
Example Violet laser uses 5.2V , 100mA
Just calculate to get rate for R1.
Power source is 7.2V -> (7.2-5.2)/ 0.100 = 20 ohm.
R2 -> 5.2V x 0.100A = 0.52W
You can add diode for wrong connection protection.
But you did know already, I need ttl function for this.
Can anyone help me?....
