So was your writter fast

So was your writter fast enough to do those Pics without a long exposure time?
rik's picture

nope

Exposures varied from 6 to 15 seconds. The face is lit by the laptop backlight at approx half a meter.

I programmed a pause in between servopos commands. See what happens when I do not pause long enough:

The motion direction is "as you would write it" without lifting the pen from the paper. Clockwise that is.

This picture DOES merit some

This picture DOES merit some beauty in it's own right.

In black and white it has a very "smoky" feel to it.

 

Love the first pics too btw :)

Do not look at laser with remaining eye

Cool! Where'd you get the light source from? Laser Pointer?
rik's picture

laser pointer indeed

Yes is used to be a laser pointer pen. It cintains a tiny smd pcb with a potmeterlet, a diode, a push button switch, a transistorette and a resistorante pico. And a laser diode of course.

The assembly also contained a small lens, diameter 6 mm, focal length approx. 12 mm. When taking the pen apart, I destroyed the lens holding construction unfortunaly. It had a threaded bus and a spring. This was used to fine tune the focus of the lens. And without a lens, the beam is just a blur. And again the shrinking tube came to the rescue. The pcb fitted in the tube perfectly, without shrinking. To adjust the focus, I push/pull the pcb in/out the tube.

Not as precise, but it works. And it is the lightest laysor assembly imaginable.
