    Update: I finally finished cleaning up my design files and released all of them (part design, solidworks drawings, BoMs, PCB boards and so on) here: github.com/alanzjl/AlkaidMount
    About the cost: I got mine HarmonicDrive CSF-17 pair for ~400 usd used from eBay. Aluminum sheets were cheap - about $60 in total. Screws ~40. I used the university machine shop so it’s free. Electronics about 100 in total (but I got enough components to make me about 10 boards:). Motor & planetary gearboxes ~100. So the total cost was about $700, very nice deal compared to a commercial RainBow HD mount that’s $3k+. I had a beginner EQ mount (HEQ-5 pro) which I got for $1.6k (during Covid) and I 100% prefer my own mount.

    Mounts have gotten so ridiculously expensive, it makes sense that people with equipment like yours would start making their own.

    • @Robin-Visser
      @Robin-Visser ปีที่แล้ว +2

      Correct. But after using one of those expensive mounts for about 3 years, your resell value is probably higher than a diy one. The increased pricings lately will also give a higher return when you sell it. Also think about the brake safety and other features that might help you to prevent costly damage to your scope

      @robin That’s a funny argument. It’s like the inverse of the “just think of all the taxes you’ll save” by taking a job with less pay. Of course it won’t be worth as much-it didn’t cost as much and doesn’t come with a pedegree. Such is the nature of diy.

      @@brandonhicks7549 i bet investing in a known brand will cost you less compared to building something yourself. Prices of branded items will probably outperform inflation. Chances are that you will sell your branded astro gear after some years of use and receive more than you paid for. Like real estate. Sometimes going cheap costs more than a good but more expensive purchase.

      I completely agree, in the country where I live there are no manufacturers so you have to import, the government charges a 60% fee on top of the value of the imported product and also on the cost of shipping, making it almost impossible to buy an EQ5 for example. I recently became interested in producing a handmade one and I'm researching the subject, I've seen that it's possible to produce one buying local material and importing some parts like stepper motors, pulleys, bearings as well as electronic components making it much more advantageous to manufacture it myself.

    I built an equatorial mount at school as a metalwork project.
    It wasn't as good as this.
    But I was only 14 with ambitions advanced beyond abilities.
    And the project began a few months before Jim, Frank and Bill enjoyed the best Christmas ever cooped up in a small tent sized can beaming grainy low resolution pictures back to us excited kids.
    My mount was based on the German type and had no drive. I just liked the idea of being able to view without constantly moving two axes.
    It bore the same relation to a professionally manufactured mount as the live TV of Neil and Buzz doing their thing does to 4K video.

  • @Ghostnotes1221
    @Ghostnotes1221 ปีที่แล้ว +1

    As a senior robotics engineer and designer, however a very new amateur astronomer, I wondered how long it would take for harmonic drives to really enter the mainstream. I bought a Losmandy G11 and immediately afterward saw the Ipotron. I almost returned the G11 knowing the capabilities this tech has. This will be the new norm in the near future. Sharing your knowledge freely, for the benefit of others is a very noble thing.
    Well done.

    Simply incredible. I have always wanted to go this route and DIY a mount to be alongside my CEM40, but unfortunately I have limited access to proper machining tools. If you do choose to release plans, it would be incredibly helpful as there are not many resources on doing something like this. The closest project I can think of is the OpenAstroTech designs, and those have a relatively small load capacity compared to your design due to them being mostly 3D printed. I look forward to seeing your other projects!

    Read the description and his comment for a wealth of information. It's flabbergasting how many spoon-fed babies there are requesting every single detail without doing any research on their own. "Screws are $40? Well what kind of screws, where do I get them, is there free shipping on screws? Can you just make me one?" Or "Refractors don't have lines, did you add them in photoshop?" And I know it seems baffling but did you know that DIY stands for Do It YOURSELF? It's not DIFM.

    First of all, fantastic job! I hate to sound negative, but when I see a DIY video, I have the impression that the project is something I could possibly achieve if I buy suggested parts and can use the tools I probably already have. Then... I see your opening shot of a complete machine shop! I'd say that along with the machining and your building the electronics from scratch, your video seems more like a pro shop making a working prototype than a DIY project. I'm afraid that even if you supplied detailed plans, all I could do is ask for a price quote if you were selling it. Still I'm pleased to see someone build their own. Maybe a local company can pick up your project and commercialize it. Best of luck.

      @NautilusGuitars 2 ปีที่แล้ว +1

      I agree. Excellent work, but not really DIY when you have an entire machine shop at your disposal.
      That said, I think if you had a modest amount of tools, like a small woodshop, you could likely do this at home with some extra work and determination. You could make the housings out of wood even, but aluminum is easy to work. To do accurate layouts in the material would be time consuming and probably a bit sloppy, but useable. He shared everything for free, so the PCBs could be outsourced for relatively cheap, either to a PCB company, or somebody with a small cnc that could mill the boards. Alternatively, if you knew anybody with a Cricut, you could have them cut the masks and etch the boards at home also.
      I'm a bit obsessive though and have developed a borderline unhealthy desire to do even the most unlikely projects at home, strictly due to habit of being too broke for anything but pure DIY. But I do think it's possible. I've done things approaching this in my little garage guitar shop.

    Gearbox in stepper motor has large backlash and low teeth quality - this will kill all benefits of harmonic gear (almost zero backlash and smooth periodic) and converts this mount to HEQ5 or worse, with jumps in guiding error graphs in PHD2... ZWO AM5 has MXL belt-pulley gear between stepper motor and harmonic reducer. Second design flaw I see - very weak ALT polar adjustment.

    Impressive skills, very nice and durable mount. How much is periodic error on those drivers?
