My local bike shop guy heard about my quixotic quest to adapt a 40 spoke Sturmey Archer hub to a 36 spoke rim with machined adapter plates, and give me another hub to play with.

It looked nice on the outside, but it did not make the expected ratcheting sound that a freewheeling hub should make when spun. It also did not work correctly.

I thought maybe it would just be full of gummed up grease inside so I poured a bunch of paint thinner in there and let it sit, but that did not fix it, so I disassembled it and found it to be extremely crusty, rusty, and gunky inside.

I'm going to try to make it work again, even though this hub still won't work on my bike because it's drilled for 28 spokes lol. It just seems fun to see if I can clean it up and fix it.

@MLE_online @wilbr I don't know if this'll work for those, they seem too large, but I've used the springs from retractable ballpoint pens as replacements in a mavic hub.

Some cool cloud diffraction from yesterday. I saw two bald eagles on my way into work today but wasn't fast enough for a pic.

Shopping for memory foam mattress toppers is an exercise in sorting through dozens of products that appear to be almost exactly the same, and each one has reviews saying it's way too hard and uncomfortable right alongside reviews saying it's way too soft and you sink into it too much.

@smellsofbikes@mastodon.social avatar

@MLE_online @Doxin same mattress topper: I think it is waaaay too soft and my wife wishes it were softer. So, yeah.

I'm trying to test thermal shutdown on an IC: if it gets hot enough, does its thermal regulation work? It has: an ADC measuring die temp via bandgap, a hardware bandgap that cuts function at a specific temperature, and a write register that you can set a value into so when it exceeds that value it shuts down. The important one, the hardware that should cut the power section, is way off. It hasn't tripped at 200C.
So today I talked to a running chip through liquid solder. That's a first.

If there is one thing that really, really, really gets on my nerve is when someone comments, "people still use $product?" in an post about a commonly used product (especially one that has become the new IE6).

How deep in your insular bubble are you? Really.

The mentality of, "Well, I don't use $product, therefore there is no reason for $product to be used or exists!" is extremely frustrating. It doesn't only exist in the tech world (looking at you car enthusiasts!).

@qlp or [company] is dead right? about a company that's doing just fine but haven't released a new product this year.

@qlp my coworker does something related: constantly angry at software that has default settings very different than how he uses it, even though his use is extremely niche. We're using financial analysis software for stats evaluation of manufacturing.

@MLE_online Before mountain bikes took over, this was ubiquitous around here, but now 85% of used bikes are mountain bikes without the option.

I started Japanese Duolingo and I’m so bad at my hiragana. I forgot everything from high school lol turns out 20 years is a long time

smellsofbikes,
@smellsofbikes@mastodon.social avatar

@danirabbit I've been working on that for a while. Have you looked at Busuu? Very similar, ads more irritating, but I think overall slightly better.

Kaman k-max helicopter with dual intermeshed blades and no tail rotor. It sounded really weird when it flew over, more whoosh whoosh than chop chop.

Cool this thing has blades made of spruce!

A dubious idea I have about cutting curved dovetails so a box would look like an impossible dovetail box, but would in fact have the top open on an arc rather than a diagonal slide like most impossible dovetails.
The axis of rotation is the left corner, where there's a green line.

smellsofbikes,
@smellsofbikes@mastodon.social avatar

It took a lot more math than I expected to make the intersections of the dovetail arcs the same width for both radii. If I were better with freecad I could make this a constraint and have the system calculate it.

smellsofbikes,
@smellsofbikes@mastodon.social avatar

@GustavinoBevilacqua One kinda neat thing about this is you could put the center of rotation at a number of different points and have different lid slide behavior depending on which it is. As the axis of rotation tends towards infinity, the behavior tends to be a slide, of course, but as it gets closer to the box, or even inside the box, the behavior gets pretty weird.

@mcdanlj I have been thinking about how I'd actually cut this. It's really cool that you took this on and I learned a bunch by looking at how you modeled it.

smellsofbikes,
@smellsofbikes@mastodon.social avatar

@kbob oh that's cool! I didn't think to try 3d printing it. I have a small CNC mill.

smellsofbikes,
@smellsofbikes@mastodon.social avatar

@mcdanlj I was not because I definitely don't have the patience to try to make a dovecutter. Although for wood I guess that might not be so bad.

smellsofbikes,
@smellsofbikes@mastodon.social avatar

@done I used the cutting revolve on this, and my math was crummy: drawing it out on graph paper and doing some trig to figure out the length of the intersecting angle was and then just assigning a value to that constraint in the sketch. @mcdanlj did a much better job in his version of it, also in the replies.
Freecad is for sure a higher learning curve. I've been using it for years so I'm kinda used to it.

smellsofbikes,
@smellsofbikes@mastodon.social avatar

@mcdanlj I would LOVE to see this, and was thinking about doing the same thing. Or giving it a run on the cnc mill and seeing if a 60 degree dovetail in pine would cut something that was Good Enough.

smellsofbikes,
@smellsofbikes@mastodon.social avatar

@mcdanlj I've played with a couple of the Assembly workbenches and whew, the amount of work I felt like I had to go through to get something moving the way I intended was really high... but it's been at least two years since I last battled that, and I know they've been working on that.

What’s the most awesome thing I saw at Hamvention? It has to be the 1964 Ford Econoline full of Collins S-Line gear

1964 Ford Econoline Van labeled “Collins Radio Company Comminications Van”. on the roof are several vintage Hustler antennas
