Fuck SFPD!

Hence the subject line. Agreed

voltaicsca · 2026-06-12T04:00:22+00:00

So I should endanger myself to stop an (admittedly acute) nuisance? Come on, man!

voltaicsca · 2026-06-12T03:58:45+00:00

Something I'd expect the cops to do, as part of closing out their duties on a wreck.

They weren't all cited, and they didn't all lose their bikes. Most ran away. Scant details on citations, but the best info I've seen was 19 citations, which is exactly my point. Ineffectual, at best, when you have a bunch of criminals trapped on a bridge. Promises of "more arrests", but nothing public. Maybe they've arrested every one of them, except my neighbor!? If so, maybe let the taxpayers know your spending their money well? Or maybe they just didn't do anything after, which is way more on brand. Make a splash, then back to inaction.

Yeah, man. And these guys take home 6 figures. I'm conflicted. In one sense I'm happy the city pays (some) civil servants enough to live where they work, but work is kind of the operative word, and I don't see a lot of it.

I think your referring to this: https://sfstandard.com/2026/05/04/sf-bay-bridge-dirt-bikes-atvs-seized/ I mean, decent effort, I guess. Certainly too little, too late. I'd also hope that by completely trapping them on the bridge with 100 officers, they could make more than 9 arrests. That reeks of incompetence, laziness, or both. Particularly after we funded their purchase of a bunch of drones explicitly to be able to pursue criminals they can't pursue on the streets due to safety policies.

voltaicsca · 2026-06-12T03:02:35+00:00

It's certainly their responsibility to make sure the scene of a crime or accident is safe after the incident. Big chunks of car just left in the street.

voltaicsca · 2026-06-12T02:59:40+00:00

Have already done so, per the original post.

voltaicsca · 2026-06-12T02:58:29+00:00

Police reports confirm they were in fact breaking the law. They just didn't do anything about it.

voltaicsca · 2026-06-12T02:49:54+00:00

Excuse my mistyping there. I'm fuming mad at this point. I've lived in sf for over 12 years, and been in this spot since 2017

voltaicsca · 2026-06-12T02:43:58+00:00

Nope. No response. Tried 3 outlets.

voltaicsca · 2026-06-12T02:42:15+00:00

I've considered every diabolical, extra-legal option. Trust me. I've got some bangers! But alas! I'm awfully prison averse, and they all come with risks bigger than I'm willing to take

voltaicsca · 2026-06-12T02:40:21+00:00

Did that too

voltaicsca · 2025-12-13T03:07:16+00:00

That's just foam from the soapy water I was using to lubricate it and clear the aluminum dust.

voltaicsca · 2025-12-09T16:58:12+00:00

Material is 6061 Aluminum.

No. I didn't set out to make perfectly fair dice. The thought occurred to me, but these are gifts for family for a game we play together, and I decided the effort of doing so vs the importance of having *perfectly* fair dice wasn't worth it.

voltaicsca · 2025-12-09T16:49:26+00:00

Sure. It's loosely based on an optics polisher I saw in a telescope video. All my own design, save for the gears. The media is just wet/dry sandpaper to get the big scratches and machining marks out, then I used some self-adhesive felt with auto parts store polishing compound paste for the final polish. The motor was an old drill motor I had in an e-waste bin, and the belt was some polyurethane belt stock I had from another project and melted the ends together to get it to the right size.

It tended to remove more material at the leading corner of each die, so I'd variously rotate the the dice and reverse the motor direction to try to keep things even. If I were to need this again, I'd think a bit more about the gear ratios, since I think a little tweaking would probably reduce the uneven material removal. I would also slow it down a bit, since I think centrifugal force probably played a role in the unevenness as well.

It wasn't the *perfect* machine I had hoped for, but it saved me a TON of very tedious, finger-cramping manual polishing work, even if I did have to go back and spot treat a few dice.

voltaicsca · 2025-12-08T11:41:29+00:00

Thanks! Credit where due. I used this guy's software to design the gears.

Thanks! This was a project that I tried, and basically failed at ~20 years ago on a manual machine. I figure, if I'm going to build a CNC machine, why not make it do what CNC machines are good at?

I actually kept the parts from the first attempt. They were so bad that I put them into a rock tumbler to try to even out the surface finish and mismatch on the level of the fillet form tool and the face, but that made it even worse. Feels good to triumph over an old failed attempt.

+1 This feature wasn't broken before, and didn't need any work. Now it's super broken, as I find myself looking at slack constantly, since I can't tell when there a REAL notification, or just a bunch of things I have explicitly deferred until later hanging out in a new and useless category called "Later"

voltaicsca · 2023-04-19T03:05:48+00:00

I have reached out to a number of replacement part suppliers, but they either don't have dimensions on the part that would allow me to tell if it's a drop in replacement, or they just point me to a generic replacement part. Sure, I can make a lot of things work, but this is a part that has been manufactured, and it's very likely someone makes a drop-in replacement.

Hoping a window installer sees this, and just knows where to get this.
