Thanks guys. Finally it started working after tenth post.

I've seen DIY topics and similar stuff here. If this is wrong place then highest authority will move it.

Finally, I've made it as separated post. Check it out. http://www.laserpointerforums.com/forums/YaBB.pl?num=1204972554

And finally - box. Hammond 8x4.5x2.5. Aluminum faceplate. Labels are made using secret military technology of heat toner transfer 8-).

Optic setup. Motors can be placed on parallel lines or form square without one side. Using square design results more compact device. Trick for easy adjustment. Use double sided sticky tape to attach motor to base, and after all adjustments, secure motor on place with hot glue. Adjustment is...

Attaching mirror to the motor. Acrylic mirror is very light, so 1/2'' double sided sticky foam tape will do job. You can use thick paper as a wedge to tilt mirror. Insert it between mirror and motor. In my setup, tilt is 2-3 degrees. It results 6' wide pattern at a distance 18'. It's...

There are two work modes, selected by toggle switch: manual and automatic. In manual mode operator controls each motor individually by twisting corresponding potentiometer connected to analog input of microcontroller. PIC constantly reads analog inputs and modifies PWM signal so duty value is...

Microcontroller PIC18F1320 handles whole routine job. PIC implements 3 channels PWM generator. PWM signal toggles MOSFET transistor 2N7000 (Id 200mA). Mirror actuator is connected as load to MOSFET. As mirror actuator I used 5V 200mA CPU cooling fan. It's easy to mount mirror on its flat side...

At first prototype I used blank DVD as reflective material but later I discovered more practical way. Technology of making FS mirror is shown in my "DIY Front Surface Mirror" video. http://www.youtube.com/watch?v=RSBBjzttfzo

PIC microcontroller based three axis laser spirograph. Design is quite simple and employs regular parts and components. Watch it in action: http://www.youtube.com/watch?v=gxwFzfvi0DY Some photos from my collection ...

I would post but I'm not allowed to insert link into message. It's not easy to share knowledge without pictures, schematics, datasheets... Have I missed something?

Potentiometer has three terminals. Side(1 and 3) terminals are connected to resistive element, so resistance between them is always constant. Medium (2) terminal is connected to slider, so resistance between it and any side terminals changes if you turn shaft. Set your multimeter to resistance...

Read datasheet. There are different packages: SOT-223 TO-252 TO-263 KTE D2 PAK Or try version for kids ;-) LM317L 100mA - TO92, SOP-8 and micro SMD package. Beauty...

200 seconds is too short period for laser show. This thing is useless for display projects :-( My unit has been ON for days during test run. But it only 5mW

I have table top version but it can show 3D patterns ;)

Thank you. I have huge gallery hosted on Flickr which contains more that 300 photos.

And few examples...

Good job Here's my PIC based version. I've made it as separated post. http://www.laserpointerforums.com/forums/YaBB.pl?num=1204972554

I've tried technology from lumenlab forum. http://www.lumenlab.com/forums/index.php?showtopic=21137&st=0 Now I'm making FS mirrors myself. Tutorial video: http://www.youtube.com/watch?v=RSBBjzttfzo Device for mirrors testing. I've made it as separated post...
