thx for this, i love it
i think thats the 135mm focal length combined with a f2 aperture and an adapter acting a bit like a macro extender
Yes, or it was, now its just the front shell with some copper tape on it
doin this every day

this is good for the 11m CB radio people
This is in fact correct, down to the frog in the pond even… https://www.youtube.com/watch?v=x5Nbc24hVHE 6:43
Those problems still sound more easy to fix than building custom mems Inkjet nozzles at home. Lasers in all sorts of wavelengths can be bought. Putting charge on the toner is just a question of adding some high voltage. The dielectric photosensitive material on the toner transfer drum, yeah that may require some research.
That’s a plotter, and opensource plotters do already exist. Problem with em is that they lack speed and precision to print small text.
Plotters are problematic, due to them beeing very very slow and that everthing they print has to be converted into a vector first.
I remember that video! For sure worth a watch
Yeah inkjet printers will probably never be opensource, due to the fact that the tiny nozzles are impossible to produce without owning a semiconductor fab that can build stuff in the mems realm.
Laser printers could be the way to go, they sound more complicated, but all the components needed for them are getting cheaper. A laser is focusable to a tiny spot, meaning one can use non mems elements. Basically take a laser engraver (the type with the fixed laser head and those 2 spinning mirrors), point it at a high voltage drum, lase the pattern (removes the charge from parts of the drum), add the toner power and then roll over paper. For color just replicate that x3.
I think a Opensource Black/White laser printer should be possible at a price point of maybe 600$ in components (3d printers also started out at that price point then got cheaper). I doubt it would be as quick as commercial models but it should be doable.
wiggle gif, very nice!
