Those framing pieces of aluminum or steel look awesome. They look great for quick mechanical structural work. Anyone have any idea where to buy them from ?

The people that presented this on stage are from SparkFun, you can likely buy all the bit from them. Most of the robot parts look like it is from the Acrobatics line that they cary:

Last month I had the disappointing surprise of finding a lock on my bike. I forgot I put it (it's been years since I last used it). And it's not a key lock.. so I'm screwed. Not willing to cut the cable.. I decided to brute force it. 999 space is fun. Luckily you quickly find similar tips than the alignment one to speed up the process. And since it's not a full rotary lock, I could also "DDR" the tests by testing whe…

In a bike workshop you frequently remove locks. It always takes seconds.

It is a bit like taking on a project and not knowing the admin password, it takes seconds if you know the codebase to fix it.

When I was 10, I found a rotary bicycle lock + connected chain, locked alone to a post in a park. Having read up on locks even then (god knows how), I tried the method of "pull on it and spin the dials". About 30 seconds later, it was unlocked. I used that lock for about 10 years, until I went to University, where the thieves were a bit smarter.

At university, I had someone accidentally lock their bike to mine with one of those. So I just unlocked and relocked it, using a similar process. (There was a lot of play in the wheels - it was a fairly cheap one.)

> if I am renting an apartment, I am SOL Not at all! If you're renting in a high-rise building, the floors will be concrete below the laminate or hardwood. A good safe will have either 4 holes or 1 center hole in the base to allow you to anchor it to the floor. Use a concrete drill bit to drill a hole in your apartment floor in a discreet area, like in a closet or laundry room. If you can borrow a hammer drill it'll…

You're advocating damaging someone's property without their permission. Don't do that.

Found the landlord!

For 1000 possible combinations, wouldn't you expect to have to try ~500 combinations on average to find solutions? Since you found it in 800 attempts, this suggests that whatever method you used may have actually made your odds of success worst.

I'm not sure how you make that inference. Could you explain your logic?

It is designed to trick people into building robots to open it? :-) More seriously though, I consulted a friend and neighbor when buying a safe for my home. This person who owns a locksmith shop and is a registered locksmith (and has been for > 20 years) asked me to look up the median response time of the police to my address. Since I live near the police station it was fairly small. He said you only need a safe that…

You bought a TL-15 safe for your home? Where did you place it? Even the smaller TL-15 safes weigh hundreds of pounds and require some logistics to place. They are very impractical for most apartment dweller types, or even some high-density, old-construction flats because of their weight.

   > You bought a TL-15 safe for your home?
Yes I did. It did not weigh hundreds of pounds. Its location was constrained a bit by where it could be secured to the structure but not unreasonably so. And it wasn't like I've got paintings or something in it, just stuff that if the house burned down I'd want to have survive and a few things I'd rather other folks not have (like passports).

Bear in mind that local governments view property crime as a form of economic stimulus. You'll be spending money to replace the stolen items, presumably some of that locally, and on repairs, presumably all locally. Meanwhile, whatever money the criminals get back in selling the stolen items (and subsequent profits by their fences) will also presumably be spent locally.

A literal broken window fallacy example. Amazing.

Seems more like helicopter money, without the goverment middleman

Wear a high-vis vest with "removals, inc." on and you can probably do it and get people to hold doors and things for you.

Funny you say that since it turned out from surveillance footage from another building that the burglars where dressed as movers and loaded all the items into a small moving van that was double parked. Forget about stealing safes from apartments, I wouldn't be shocked if you could rob an actual bank vault by dressing as a construction crew.

University I went to had this happen in the summer. Showed up in coveralls and had a paper for the RA to sign. Cleared out all the furniture and appliances. Told the RA that the new stuff was a bit late but would be there in an hour. They were not caught but I question the target’s value.

Police response is what, 6 minutes? Can you open the safe in 6 minutes after cutting the power? Probably not.

Cut communications hardlines to the building, and also use a cell scrambler.

If a building has that level of protection, I'd hope its fail closed not open.
