We’ve got a love-hate relationship with discount tool outlet Harbor Freight: we hate that we love it so much. Apparently, [James Clough] is of much the same opinion, at least now that he’s looked into the quality of their outlet strips and found it somewhat wanting.

The outlet strips in question are Harbor Freight’s four-foot-long, twelve-outlet strips, three of which are visible from where this is being written. [James] has a bunch of them too, but when he noticed an intermittent ground connection while using an outlet tester, he channeled his inner [Big Clive] and tore one of the $20 strips to bits. The problem appears to be poor quality of the contacts within each outlet, which don’t have enough spring pre-load to maintain connection with the ground pin on the plug when it’s wiggled around. Actually, the contacts for the hot and neutral don’t look all that trustworthy either, and the wiring between the outlets is pretty sketchy too. The video below shows the horrors within.

What’s to be done about this state of affairs? That’s up to you, of course. We performed the same test on all our outlets and the ground connections all seemed solid. So maybe [James] just got a bad batch, but he’s still in the market for better-quality strips. That’s going to cost him, though, since similar strips with better outlets are about four times the price of the Harbor Freight units. We did find a similar strip at Home Depot for about twice the price of the HF units, but we can’t vouch for the quality. As always, caveat emptor.

Thanks to [cliff claven] for the tip.

A moment’s inattention is all it takes to gather the information needed to make a physical copy of a key. It’s not necessarily an easy process, though, so if pen testing is your game, something like this Flipper Zero key copying toolchain can make the process quicker and easier when the opportunity presents itself.

Of course, we’re not advocating for any illegal here; this is just another tool for your lock-sports bag of tricks. And yes, there are plenty of other ways to accomplish this, but using a Flipper Zero to attack a strictly mechanical lock is kind of neat. The toolchain posted by [No-Lock216] starts with an app called KeyCopier, which draws a virtual key blank on the Flipper Zero screen. The app allows you to move the baseline for each pin to the proper depth, quickly recording the bitting for the key. Later, the bitting can be entered into an online app called keygen which, along with information on the brand of lock and its warding, can produce an STL file suitable for downloading and printing.

Again, there are a ton of ways to make a copy of a key if you have physical access to it, and the comments of the original Reddit post were filled with suggestions amusingly missing the entire point of this. Yes, you can get a key cut at any hardware store for a buck or two that will obviously last a lot longer than a 3D-printed copy. But if you only have a few seconds to gather the data from the key, an app like KeyCopier could be really convenient. Personally, we’d find a smartphone app handier, but if you’ve got a Flipper, why not leverage it?
