Robotic sputnik tool, it is very slick. Something that's not obvious is that these work best on ABUS or other locks that have one solid driver pin and spools in every remaining pin stack. This way, when you locate and lift the solid driver pin, you gain a ton of "back and forth slack" in the plug. As you lift each successive spool driver the slack reduces until the shear line is hit on that pin stack and suddenly full slack again; repeat the process until the lock is open.

The devil is in the details though, there are some subtle features that need to be incorporated into the mechanics for the sputnik to work right. I have built a sputnik from scratch before, only after talking to Oli Diederichsen at a LockCon did I get some additional clues.

Also, I think there are plenty of other interesting things one could do besides brute forcing the lock with a simpler tool. Falle Safe has a single-wire variant on this for decoding locks. Again, the devil is in the details, just ramming wire up a pin stack doesn't get the job done.

It's not an accident that its so hard to get this stuff right, I've heard countless stories like this from friends who are parents.

If the market wanted parents to be able to figure this out it would be getting it right. It's obviously a dark pattern that benefits everyone but the parents and their children. If more people stopped to think deeper about this they would and should be very disturbed by what this means.

Man, this brings back memories of playing with Festival back in the day. I wrote a bunch of scripts to generate dynamic Festival text2speech audio for a Part15 AM radio station, a virtual radio station DJ over 15 years ago. The intelligibility was not great back then, the funny thing was after spending many hours listening and tweaking my input text I trained myself to understand the default voice a lot better. Other people had a hard time with the default voice but I could understand it perfectly. Thankfully some of the improved voices available back then helped it a lot.

To fix pronunciation problems I had developed a set of domain-specific "dictionaries", sed substitution scripts that would translate certain words and phrases into their phonetic versions that would be pronounced better by Festival. Besides announcing the names of songs being played, I was also feeding news articles and some other web-scraped info through it. Tons of fun to hear your project working on the air in public as you drive around town.

What I don't understand is why it took you 8 weeks to distinguish a timer from a transistor. That doesn't make your professor's reaction alright, I just find it puzzling.

Ohm lordy, we're blaming the student for not having years of homebrew experience before he entered school? Sure any hobbiest knows what a 555 is, but when the lab assistant doesn't even catch it and the chip was handed out to the student this is not an entry-level students fault.

Yes we do. It was a sewer inspection van. If it was the NSA, their van wouldn't look so goofy that people took one look at the photo and assumed it had to be an NSA van, which is what happened here. This is a bad movie plot trope: the bad guys can't simultaneously be omniscient and so dumb they're trivially outed like this, just like the real supervillain isn't going to monologue while you free yourself from the chains lowering you into the shark tank.

Regardless of what the real story is on this van, lookup the Bernie S. case if you want an easy case with proof of government surveillance incompetence. Under cover Secret Service agents were photographed surveilling a 2600 meeting in a mall court, then got embarrassed when the 2600 guys posted flyers with their photographs around. Most criminals are dumb which is a good thing as I like the bad guys getting caught, but unfortunately the smart ones graduate to become politicians.

To use an LBA HDD or especially a SSD as well as DOS can, I've always found that the DOS from W98SE, with the 2001 update, is about the most reliable.

The only repeatable way when ongoing testing is underway is to zero the media each time, since many times DOS will rely strongest on what is already there during a Format or SYS. So will every version of Windows, but without full consistency at all.

If using Win10 or 11, you may find that even with a zeroed floppy or HDD partition when you power off, the partition will be silently formatted just as Windows last remembers it when you reboot, transparently without notice.

Plus even with successfully zeroed media, there is often a difference in what the Format comes out like depending on whether you booted the PC to an actual floppy, HDD, or SSD, and what their geometry was. And this can often come out different on different motherboards because of their dissimilar bios recognition of what the geometry is and what will be compatible with potential booting on that particular device.

Other times it seemed like some bioses were not suitable for formatting some media well enough to be bootable on their own device. But worked just fine if formatted on a more "universal" motherboard, then boot fine on the problem PC.

These days I want my FAT32 volumes, which are often being used as boot volumes as expected under UEFI, to be fully formatted under DOS for best reliability. None of the intentionally lesser stuff ever since. But I also want my structure to align with 4096 byte sectors which really helps with AF HDDs and SSDs. DOS won't do this on its own. Plus Windows mostly defaults to putting the bootsector at 2048 now instead of 63 on LBA gear, so I format a zeroed FAT32 partition using Windows 10 or 11 first. Then to the disk editor where everything is re-zeroed except the bootsector and the following 8 sectors. Edit the bootsector & backup bootsector (6 sectors later) for 2048 Hidden Sectors. And 2048, 4096 or a multiple of 4096 Sectors Per Fat, depending on which multiple is closest to the value that was there by default (according to the size of the partition) when there was no awareness of SSDs.

Then back to DOS and Format /Q, on a good motherboard it will retain the values you edited in, and you've got a more reliable foundation for your boot files or anything else.

Heh, reminds me of the days I kept Win95 and Win98 DOS boot disks for emergency booting Windows machines.

Ah yes, memories of my laptop, an Orinoco card, and Netstumbler cruising down the highway during my day-job. Shortly after that I added an X-10 video receiver and a USB Hauppauge WinTV adapter to capture video transmitters too. I'd reach over and trigger a screen-shot whenever live video came into view. Once in a while I'd even capture myself driving through a parking lot or something on the feed.
