Just got into astronomy, been looking at many diy mounts and this by far is the best ive seen. Unfortunately even with all the information provided im far too dumb to design it let alone building and assembly. Its beautiful though absolutely amazing work!
Wow! Great video and building this new Harmonic Drive mount.. I liked.. I am new in your RU-vid canal. One questions the Harmonic Drive Motor are Swiss made or from China? I can imagine, when are Swiss made are too much expensive but better with Swiss made encoders as from China, are not so great and full quality the same that the company RST-Raimbow used for she mount. Your mount are one new concept and great. I hope you can more building. Greetings from Switzerland.
How did you assemble your harmonic drive gear and how did you connect the harmonic drive gear to the shaft of the stepper motor? I ruined one of my harmonic drive gears because I could not find instructions anywhere as to how to assemble it properly and then connect it properly to the stepper motor shaft. Thank you in advance.
bot at all this fancy, I built my EQ3 mount's driver, but with ST4, multiple speeds, backlash etc, around an ESP32, keeping the factory motors on my ancient mount.
Comme tout le monde, ont ne peut être que admiratif devant le travail accompli. De la conception jusqu'à la finalité sous les étoiles. Et pour un coût défiant toute concurrence... Et merci pour la musique, surtout Jean Michel Jarre 👍 Clear sky🌌
As an engineer, programmer and network security professional... I was like WTFFFF? What is up with this set of skills?!? And then I saw MIT and it all made sense LOL. Awesome work man!
It's in the description " I built a portable, lightweight, yet mighty equatorial mount with two HarmonicDrive gearboxes. The EQ mount weighs about 16lbs and can support 25lbs without counterweights, or 70+lbs with counterweights. "
There's a "trick" to get score marks on glass to break cleanly! For starters you need to make your score marks fairly light, as the _harder_ you scribe into the glass you end up making TONS of tiny fractal chips where the break can spread off in tangents! Use a metal ruler as a guide too, so the scribe mark is straight. Search for a video called "Wine Bottle Cutter 30 seconds Perfect Edge Glass Bottle Cutting GreenPowerScience Guitar Slide"... Check it out and maybe try again!
The work was Rad and the Build was cathartic to watch… Although, The noise/sounds starting at 1:25 through 4:45 were painful..At best😶…. had to turn the sound completely off during that entire part. It really Was truly a Bad pick, astonishingly even....Aside from that Distraction(to be kind) the Rest was Excellent🤙🏻.. Thanks for files..The ol, DIY Cnc will have to do… Super Rad!..
Very nice technical project, wonderful. but just a total nonsense from photographical POV. why to use a 6x17 capable lense to downgrade quality to a 35mm film. strnage to me.
Does the use of a planetary gear reduction negate the advantages of zero backlash of the harmonic drive? Do you have any results on the tracking performance?
Very nice work ;-) It makes me want to use my printer again very soon. @4:20 I would always choose black material and not paint it… And yes, you won yourself a new subscriber ;-)
I liked the montage. Suitable for a small astrograph. But to make all the parts, a vice, a hacksaw for metal, a file and an electric drill are enough. The polar axis tilt assembly axis can be replaced with a simple bolt.
@@jeffb.7951 thank you! I'm thinking most of these commenters have never heard of a makerspace. I live by one of the very large ones in DFW and we have everything needed to make this except we have a CNC plasma instead of a waterjet. That would require more material cleanup, but it's all very doable. I'm curious about the materials cost though. I didn't see a detailed BOM (just a general one), so I'll have to figure out the costs. This might make a great group project at my makerspace. I'm sure there are others there interested in astronomy too! 🤔
