Great stuff! I have a few modifications that you and/or the community might want to make/add:
It would be good to add a section that tells the right way to insert the line generating lenses - ridged side “in” (towards laser) or ridged side “out” away from laser. Perhaps show the resulting beam both ways so that improper installation can be visibly detected.
It would also be good to show how to wire the lasers electrically as this seems to come up often - it would be great in this section to show how to power the lasers off a standard power supply (perhaps one of the Aixiz models which people are likely to buy) as well as how to tap into a PC power supply off a molex connector.
Also one minor grammatical change - In the “disclaimer” section - replace ‘stair’ with ‘stare’
The images of focusing the laser and the resulting blobs are fantastic. Really appreciate the effort that went into this. I also agree that it should be included in the NUI bible - just add the two sections above
Thanks for assembling this data I think many of us in the community will find it immensely helpful as we continue our builds.
