I'm trying to figure out crypto right now, could you explain why you believe this? Or link somewhere where I can read about it?

Tether has been extremely opaque in what assets they hold to ensure the 1:1 USD/Tether peg. It's been observed that at least as one point they definitely didn't have enough USD-equivalent for it, and they've been issuing new Tether at quite a clip since then with flow on effects to the BTC market. Now if they actually had this financing in place, this would all be fine - but nobody can find a proper accounting of who…

Tether is just one of many cryptocurrencies -wouldn‘t its implosion lead to people pulling out and investing their money in other crypto, hence consolidating the market and making every other coin rise?

If from the Coinbase IPO, you just got out of lockout and you're new to that amount of money. You're probably still near 100% invested in Coinbase and need to divest into something more diversified and less volatile than Coinbase before you can sit on your hands and look at the number in your brokerage account as if it was real retirement grade money. Plus you'll need to pay a ton of taxes on the capital gain. So don…

There's a Ask HN thread, maybe a few, of people who hit it rich and later lost it. The common theme is it's easier to make lots of money than it is to keep it, which is a little unintuitive.

thanks for sharing, storing thst up in the noggin

Agree with waalo. For me the thing I enjoy is that you are setting realistic expectations, not being wasteful (I notice you start from the edge of the paper instead of cutting from the middle, etc.)

The lack of any kind of commentary on the second video gives me strong ASMR-but-for-papercraft vibes. I would watch that even as a grown-up.

yeah, I heard this from others as well but not something I particularly aim for at the moment (I could easily release a second version of a video with the original sound though). Although sound/music is one of the bigger questions/challenges I need to 'solve': it's quite difficult to strike a balance between setting the mood for a video and too intrusive. Pure original sound is difficult for other reasons, mic quality, background noise etc.

Hah this thread is perfect. I just finished building my new four axis robot arm design. It’s all open source. Three months ago I started playing with a new planetary gearbox concept, where the first stage is in the middle with second stages on both sides. The first sun is driven by a shaft that goes through a hole in the second stage sun. The result is a very balanced joint design with parallel outputs. A good config…

I count three axes, what am I missing? (considering the "stick" at the top "a finger" and moving down, I see the wrist rotation, the elbow rotation, and a rotation at the shoulder down on the desk)

So in the video you first see a section of movement using the second and fourth axes. Then after that the arm goes back to zero (sticking straight up) and you see the midsection rotate back and forth without the end section rotating. That’s the other two axes. There are also closer photos here:

Wow awesome. This is one of the most impressive arms I've seen. How much did it cost you to build? About how many newtons can you excert when fully extended? / What weight can you lift? What is your experience with backlash? Definitely considering forking

Thank you! I had all the parts lying around and I’ve not put together a full BOM to calculate costs. But it’s two odrives and four brushless motors plus maybe $100-150 in bearings from AliExpress, then some screws and a couple kilos of PETG. So maybe $850 if you built it from scratch? I haven’t done testing of its capabilities yet as I just got it working today. Also I am running at 24v but I want to try 48v when I c…

Also it should be noted that with my $850 estimate that is $400 worth of Odrives. For years I have longed for good brushless drives for under $100 per channel and there are some newer ones out there. But basically brushless drivers are a major chunk of the price which I think could be reduced with cheaper custom drivers.

Too many ideas given the time, but now I'm focused on two: 1. Building an open source bicycle computer. It's been over 20 years since they arrived at the scene, and there still isn't one that you could hack! An outrage! No published sources yet, I'm getting stuck on not having much experience building physical things. 2. Getting rid of the directory hierarchy. I have 10K photos, 30K emails, 10000km of GPS tracks, and…

How much would you pay for a program that would help you do 2 way more effectively than just by querying it?

consider starting a family :-)

Ha! I've considered it and if I found the right woman and we had a relationship that was in the right place I'd definitely do it. But starting a family seems like one of those 'slow and steady wins the race' type of situations.

For many of my acquaintances, starting a family was a jump in the deep end and sink or swim.

As for end results for child and parents, I am really unsure whether slow-and-planned beats random-pregnancy-and-shotgun-fatherhood. Both succeed and both fail.
