The Worst Piece Of Test Equipment You’ve Got To Try Hacking

I have a fascination with the various online vendors of electronics and other manufactured goods from China. Here are listed the latest wonders from Shenzhen or wherever, which you can have for a surprisingly reasonable price, with the mild inconvenience of a three week wait for the postage.

A particular pastime of mine is to look for the bottom end of the market. Once I’ve picked up the items I came to order I’ll trawl around with the search with low price first and see what can be had for a few dollars. Yes, I take a delight in finding absolute trash, because just sometimes that way you can find a diamond in the rough.

So when I was shopping for a multimeter recently I took a quick look to see what the cheapest model from that particular supplier was. For somewhere around £2.50 or just over $3, I could have a little pocket analogue multimeter, the kind of “My first multimeter” that one might have found in the 1980s. They weren’t too bad, I thought, and ordered one for less than a pint of beer in a British pub.

Why You Should Use Your Router As A Security Camera

November 28, 2017 by Lewin Day 28 Comments

A home security camera can be great for peace of mind, and keeping an eye on the house while you’re away. The popular option these days is an IP-based device that is accessible over the Internet through an ethernet or wireless connection to your home router. But what if you could cut out the middle man, and instead turn your router itself into the security camera? [Fred] is here to show us how it’s done .

The hack begins by parsing the original router’s firmware. Through a simple text search, a debug page was identified which allowed telnet access to the router to be enabled. This gives access to a root shell, allowing full control over the Linux system running the show.

After backing everything up, [Fred] grabbed the source code from Netgear and recompiled the kernal with USB video and Video4Linux2 support. This allows the router to talk to a standard USB webcam. It’s then a simple matter of using opkg to install software to set up the router to record video when motion is detected.

Overall, it’s fairly straightforward, but [Fred] came up with an ingenious twist. Because the router itself is acting as the security camera, he is able to set up the camera to only arm itself when his smartphone (and thus, [Fred] himself) is not at home. This prevents the recording of footage of [Fred] moving around the house, allowing the router to only record important footage for security purposes.

It’s possible to do great things with routers – most of them are just tiny boxes running Linux anyway. Check out this one used as an online energy meter.

Russian Drone Can Lift 142 Phantom 3 Drones

Russia has long been known for making large machines. They hold the current record for the largest helicopter ever made – the MiL V12. Same goes for the world’s largest airplane, the Antonov An-225. Largest submarine? Yep, they made that too – the Typhoon class. It would appear they’ve thrown their hat in the drone business as well.

While the SKYF drone is made by a private Russian company, it is one of the largest drones we’ve ever seen. Able to lift 400 pounds (a Phantom 3 weighs 2.8 pounds) and can fly for eight hours, the SKYF drone is a nice piece of aeronautical engineering. Quad-copter style drones provide lift by brute force, and are typically plagued with low lift capacities and short flight times. The SKYF triumphs over these limitations by using gasoline powered engines for lift and electric motors for navigation.

It’s still in the prototype stage and being advertised for use in natural disasters and the agriculture industry. Check out the video in the link above to see the SKYF in action.

What’s the largest drone you’ve seen?
