I personally DIYed mine and it took a lot of tinkering to get a reliable setup. The kit is very well polished and uses the new NEMA steppers. As for pricing, I think it includes 20% VAT, which I assume is removed if you are not in the EU. I personally have spoken to the creator and they have tried very hard to make it as low cost as possible. If you have a 3D printer and live in a country with decent hardware suppliers (not the case for me in Australia), then sure go ahead, DIY and save money. But for people who want an almost ready to go solution it's very well priced, considering commercial alternatives are well into 500+ for the feature set that this mount offers (GoTo, optional guiding down to 1" accuracy).

So if I understand you correctly, it's the R&D that makes up the majority of the price, not the components? Not saying that's bad, just that my question is what makes this cost what it does. If it weren't justified, there'd be competitors doing it way cheaper (the field is accessible and large enough for that), so it's just a question out of curiosity.

  Not quite - if they priced in all of the dev effort required to make the mount software compatible (ASCOM, etc) it would be much higher I think. From what I see, ensuring the 3D printed parts are up to spec and look good cosmetically requires a lot of time, not to mention manually wiring and flashing all the electronics.

  Have you seen how many parts there are? It would probably take most people with a normal day job a week to print all parts in the evenings and weekend. And that's if they do have a printer. Add another 20 parts that you need to order from different place, make sure they meet the specifications, pay for shipping for a lot of different packages and that many things must be bought in bulk and not single pieces. USD 200 is a bargain for this kit. Sure, you might be able to save a couple of dollars if you do the work yourself. But is that worth many hours of work, and the risk of ordering wrong stuff?

  Of course the R&D makes upt the majority of the price. When is that ever not the case? The version that is available now is not the only version that was made. This is something that has been thought about, made, revised, made again, etc. Things like this often go through multiple iterations. Hell, there will probably be a OpenAstroTracker 2.0 in a year.

    > Of course the R&D makes upt the majority of the price. When is that ever not the case? Like, pretty much every other product that wasn't an entirely new concept in the last few years? Looking around me, I think the thing with the highest R&D price component is probably the chips in computers (desktop, laptop, smartphones), everything else is just mass production and low markup with hardly any research recuperation in the price (keyboard, lamp, paper, desk, floor, beanbag, fridge, IR thermometer, picture frames, a spoon, a computer display...). Unless you meant "when is that not the case for astro trackers", I don't get what you meant because it's rather exceptional to still be paying off R&D if you're buying regular mass-produced consumer products. > This is something that has been thought about, Obviously, but if it's open source (with a free, commercial-use license and no big call for donations other than a coffee) then apparently recuperation that design time is not a goal, they're actively giving it away for free and encouraging people to make it themselves. That suggested to me that the price must be for an expensive component or two. Or perhaps the printing time, but since it's mostly unattended and filament is cheap, I didn't expect it to be that. And the tracking calculations have been long done by people decades ago, so it's just buying parts and putting them together, where the "putting together" part is done by the customer since it's a kit. So yeah I expected the price to be mostly an expensive precise motor or something.

      Great, Apple's new M1 based systems now exist on the market. Go make one for me for less than what Apple sells theirs. Should be easy according you since someone else is already doing it. R&D is everything in making of something. Just because someone else made it doesn't mean you get to start exactly where they left off (except in cases of open source where you get their literal plans). Even in wood working or any shop type of work, you often spend more time setting up things like jigs or other custom tooling than it takes to do the actual work. Is that supposed to be a sunk cost to the builder? No, it is part of how the builder arrives at the price of the final thing being built.
