Alexa, Hack My TV

Posted on by

If you have an Alexa, one of the best things you can buy to go with it is a Harmony Hub remote. Sure, you get a universal remote to control all your home theater equipment, but you’ll hardly use it because the Alexa can virtually push the Harmony buttons for you. The negative word in this paragraph, though, is “buy.” The Harmony Hub isn’t inexpensive. Fortunately [Michael Higginis] has you covered. He has an ESP8266 universal remote that you can control with Alexa. You can see a video of setting the system up below.

On the one hand, the idea …read more

Twin Pis for Remote Computer Management

Posted on by

Sometimes you have a whole bunch of computers that you need to work with, and having a keyboard, monitor, and mouse for each one becomes too much to deal with. There are a multitude of solutions to this problem, but [Fmstrat] went the hacker route, and built their own.

The build is a rather unique way of controlling PCs remotely, but it does the job. A Raspberry Pi 3 is pressed into service as the core of the operation. It’s accessible over IP for remote control. Video is captured from the controlled machines through the combination of an HDMI-to-S-Video adapter …read more

Cheap RC Truck Mod Is Slightly Risky Fun

Posted on by

The world of RC can be neatly split into two separate groups: models and toys. The RC models are generally big, complex, and as you’d imagine, more expensive. On the other hand, the RC toys are cheap and readily available. While not as powerful or capable as their more expensive siblings, they can often be a lot of fun; especially since the lower costs means a crash doesn’t put too big of a ding into to your wallet.

With his latest mod, [PoppaFixIt] has attempted to bridge the gap between toy and model by sticking a considerably overpowered battery into …read more

Earth Rovers Explore Our Own Planet

Posted on by

While Mars is currently under close scrutiny by NASA and other space agencies, there is still a lot of exploring to do here on Earth. But if you would like to explore a corner of our own planet in the same way NASA that explores Mars, it’s possible to send your own rover to a place and have it send back pictures and data for you, rather than go there yourself. This is what [Norbert Heinz]’s Earth Explorer robots do, and anyone can drive any of the robots to explore whatever locations they happen to be in.

A major goal …read more

In-Band Signaling: Quindar Tones

Posted on by

So far in this brief series on in-band signaling, we looked at two of the common methods of providing control signals along with the main content of a transmission: DTMF for Touch-Tone dialing, and coded-squelch systems for two-way radio. For this installment, we’ll look at something that far fewer people have ever used, but almost everyone has heard: Quindar tones.

What’s a Quindar?

You may never have heard what Quindar tones are, but you’ve certainly heard them if you’ve ever seen any manned spaceflight videos. Quindar tones are those short beeps you hear when NASA is communicating with astronauts, as …read more

Video Streaming Like Your Raspberry Pi Depended On It

Posted on by

The Raspberry Pi is an incredibly versatile computing platform, particularly when it comes to embedded applications. They’re used in all kinds of security and monitoring projects to take still shots over time, or record video footage for later review. It’s remarkably easy to do, and there’s a wide variety of tools available to get the job done.

However, if you need live video with as little latency as possible, things get more difficult. I was building a remotely controlled vehicle that uses the cellular data network for communication. Minimizing latency was key to making the vehicle easy to drive. Thus …read more

We Dig This LEGO Excavator Conversion

Posted on by

[Frank] was lucky enough to score a bucket wheel excavator LEGO set as a birthday present, and we won’t lie – we’re jealous. However, out of the box, the kit is somewhat limited; there is only one motor to animate the entire machine and it can’t be fully remote controlled. But don’t worry — [Frank] set out to change that (Google Translation).

The first part of the build was to add motors to control the different functions of the excavator. One motor was added for each of the two tracks to allow the machine to drive forwards, backwards, and turn. …read more

Just In Time For Summer: A Remote Controlled Snowblower

Posted on by

It’s May, and you know what that means: we’re winding down from a worldwide celebration of the worker, pollen is everywhere, Hackaday readers in the southern hemisphere are somehow offended, and somewhere, someone is finishing up a remote-controlled snow blower build.

In this nine-part, two-hour-long video series, [Dave] covers the planning and fabrication of one of the most coveted of all cold weather yard instruments. It’s a remote-controlled snow blower. Just think: instead of bundling up to go blow the driveway off, [Dave] can get all the snow off his driveway from the comfort of his living room window. Sure, …read more

Half Baked IoT Stove Could Be Used As A Remote Controlled Arson Device

Posted on by

[Pen Test Partners] have found some really scary vulnerabilities in AGA range cookers. They are connected by SMS by which a mobile app sends an unauthenticated SMS to the AGA to give it commands for instance preheat the oven, You can also just tell your AGA to turn everything on at once.

The problem is with the web interface; it allows an attacker to check if a user’s cell phone is already registered, allowing for a slow but effective enumeration attack. Once the attacker finds a registered device, all they need to do is send an SMS, as messages are …read more

Retrotechtacular: How Old is the Remote?

Posted on by

A few weeks ago we covered a (probably) bogus post about controlling a TV with the IR from a flame. That got us thinking about what the real origin of the remote control was. We knew a story about the 38 kHz frequency commonly used to modulate the IR. We’ve heard that it was from sonar crystals used in earlier sonic versions of remotes. Was that true? Or just an urban myth? We set out to find out.

Surprise! Remotes are Old!

If you are a younger reader, you might assume TVs have always had remotes. But for many of …read more
