Hey I love your channel and this was a great build. I was kind of amazed that you manged to get optical sun tracking working without it being too erratic. Amazing. I'm a long time fan. I loved when you doubled down on the metal 3D printing and went Tig. That was quite a build. Anyway. My friend Lawrence and I built a solar plotter like this a while ago, and we did the sun tracking in software. If you have the x axis level, and just use a plumb stick to aim the entire rig at the sun, you can use current time + log/lat to apply incremental offsets to your gcode that compensate for the suns motion! (Won't work well for some 3 hour plot, but for something that only takes 40 mins to plot it works great, and is very simple/easy to set up.) Although you have to estimate gcode temporal position which can also get a bit off on longer plots. Sorry this kzbin.info/www/bejne/in_alnijqd2nqNE is not a good video, but we actually eventually got some very nice output out of that rig. Be warned that trying to go with an iris for variable line width is difficult. I built this iris kzbin.info/www/bejne/jXmzo3p-d8yml6M , and did a bunch of tests but when the iris is too small there's just not enough heat to char wood, so the range of widths was fat->super fat, which wasn't that interesting. You might be able to reduce sfpm or have better optics to get very fine lines but just controlling the magnifying glass "size" with an iris works less well then you'd think, so be warned. Anyway. Keep up the good work! I'm ok with you posting more erraticly. Hell, I only post once or twice a year. lol.

Dude, that is a super cool way to solve the whole "moving sun" problem. Thanks for the insights on the iris, I'll take that into account. Although after watching your video I may have to make one just because it looks so dang cool!
@retrotechjournal2 жыл бұрын
@@cranktowncity Yes, far more things should have motorized irises! I think part of the problem is that wood is just inherently a bit inconsistent so you can't be too close the "enough energy to cause charring" threshold or you get super inconsistent lines. I wrote an Illustrator g-code exporter for that project. I was hoping to then export line widths as z-axis positions to drive the iris, but never got a useful range of widths/results I was happy with. I can totally identify with all the "Oh god! I can't see my laptop screen in the noon day sun. I can't believe I'm using this laptop under a blanket in the full heat of the sun." wackiness that comes when operating a solar plotter. I can't wait to see what you do with it next!

nice. you should try a fresnel lens to speed up burn rate. I got a pack of 4x10 lenses for cheap as free of the internet and they have a pretty sharp focal point if you hold them rigidly. also gives you a larger area to cover with a shade for power modulation.
@Impatient_Ape2 жыл бұрын
Neat-o, man! If you were wondering how narrow you could get the burn lines, here ya go... Even with a "perfect" convex lens, the diameter of the sun's image in the "hot spot" will be approximately equal to the lens focal length F divided by 107. However, heat spreading will end up giving you an even wider burn trail. (The math : the sun's angular width is approx 0.533 degrees. This is also the angular width of the hot spot image. So the ratio of the hot spot size to the focal length is equal to the tangent of 0.533 degrees, which is approx 1/107)

And if you add the plate a bit higher up, then the sun will not focus as much, so it will be even less dangerous then.

@Cranktown City I remember seeing online a solar 3D printer a while ago. I think it used a big fresnel lens to melt the sand layer by layer (*found it: Markus Kayser - solar sinter project). Also, what's the delay between repositionings of the tracker? Could it be possible to log the values for a day and average them smoothly? I mean, with such sluggish speed the thing requires (because low energy per minute), it might lose precision during the run due to Earth's rotation. I have a humble suggestion: more power! -inflated mylar concave mirrors, each with its own tracker -a solar tube (roof style) to gather all of them -mirrors and a collimator to put the light where you want it A lens to make a little dot hotter than the sun Same cnc rig Btw I loved every second of your video in all of its 1x glory, awesome.

We made a mini version of this in my college robotics class (minus the lens and engraver, just the solar tracker) using four steppers, one in each corner of the plate, and aball socket in the center of the plate. The steppers would lift or lower the corners accordingly. You could try something like that for the base with lead screws attached to ball socket joints on each corner and nothing in the middle
@roberthercules31592 жыл бұрын
What do you think about possibly adapting your mirror setup from the co2 CNC laser? Use a heliostat to focus sunlight through a large lens (maybe a fresnel sheet/panel), then re-collimate it with a regular convex lense (place PAST the focal-point of the fresnel) onto the first mrror (which will be the last of the 3 optical components that have to be mounted heliostatically) to bounce it across the x/y/z mirrors of a normal co2-laser (style) machine. After that, you'd have all of the movement completed for a very high power (and far more precise/stable) cnc "laser" finished, and if you wanted to do raster & non-cutting moves, either a metal plate on a solenoid, or (to be super-fancy) a piece of liquid-crystal window glass, could be mounted pretty much anywhere NOT at a "focal point" of the beam, to allow some PWM control of the power. Then, you could do rasters & non-burning moves, with the only unsolved problem being how to compensate for clouds passing between your power source (the sun) & your workpiece.

Shoulda used a lenticular lens - one of those flat plastic lens sheets. Then you could have a big fat solar collector to focus more sun down to a hot burning dot. I think rigidity isn't super important, but more so the sun-tracking itself. You can't have the tracking going while it's cutting with it being so jerky, it needs to be smoothly tracking the sun. The photoresistors should be super close to the vanes of the thing and the MCU should be sorta just slowly averaging/weighting the measured intensity and gradually actuating accordingly. It looks like the way it is, or was during recording of the video, that it would just screw up a "cut" if it tracked the sun while in the middle of burning something. You want it to track the sun super duper smooth, constantly, so that you can be burning a design and have it come out perfect. Regardless, pretty super dope man!
