Wow ..... !!

Hi, i would have a look here: https://www.arduino.cc/en/Reference/Stepper https://github.com/arduino-libraries/Stepper

Thanks for showing ... !

There is realy a great difference in scattering , reflection and diffaction. Reflection backwards and scattering backwards is not so strong as the diffraction in the beam direction ...

Hi Richard A, i am interested in this project, but i think i would not be able to solder smd .....

Hi Richard! Thanks for sharing with us, interesting.......great ....realy great

Thanks a lot for showing us such impressions .... very nice !

You see ... ask Paul .....

So it is as Paul said, 5v on 0v off normaly, i have some where it is inverted or you can invert by a swich. To use something like a powercontrol for this laser you have to trigger a ttl signal , the driver is ttl.

Could you please post a picture?

Hello, since I was asked here how the project is going on, i have decided to skip a few intermediate and test series as a posting. Here are the essential parts for a complete device. The various components should be attached to a microscope in one of the possible configurations. At this...

Use "sodial 5.5 power" and you will find them quick.

By the way, you must not cut off male 5.5mm round plug from the power cord , i made it in this way, bought as pairs here (and you must not solder) . screw the female at the other end of the JST cable, an you are ready...

Oh, sorry, attention, i got 200 of these jst connectors with 1.5mm ...they will not fit at the driver , because they has to have a pitch of 2.5mm .... search for jst xh like these https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.de%2Fulk%2Fitm%2F273051496579 Verify the pitch

WOW, i have never seen a 195 G-pix picture, thanks for sharing!!

Hello, First of all, I am very pleased that here is a little movement again. So such communication is very constrictive and helpful to all. Hi Paul, here you describe the diffractive resolution of the very good USB2000. Dividing the spectral width of a system by the number of pixels...
