Well, what's so funny. The output of household Ulf audio signal "ground" under your speakers. Patibility laser illuminates only(!) with a few Watts of power ucilka! He(LM) you need the voltage modulated by the audio signal. The principle is the same as for the chasers or the equalizer. In my opinion, the problem is solved by a simple cascade of a single transistor connected to the output of the player. Three cell battery is enough for several days of operation of the amplifier in two channels and two LM. I could be wrong of course, time will tell.Шалтай Балтай wrote:he smiledАлександр Н. wrote:The power of the laser module 5mW, one channel of my ucilka 20W
My knowledge in electronics is minimal, so can someone tell me if there are hams on the forum. What excites the coil Mobius? the electricity voltage? Means open collector transistor is the best option, without loss of capacity? How to protect the coil and the transistor from overheating? A voltage divider? As well included in the circuit to fine-tune the threshold for overheating?
Looking for two real stores and one online store, all the LM power up to 5mW. Saw a laser pointer (LU) to 700мВт, they are in the case and with batteries. But the price tag accordingly. Thinking about buying and recast for these purposes. Well, the crystal looked closely corresponding in diameter hand does not embrace. Beauty will.<Шалтай Балтай wrote:LM are different.Александр Н. wrote:because power 5mW laser even on light pulls
