How To Control the Lights with a TV Remote

Posted on by

In this day and age of the Internet of Things and controlling appliances over the internet, the idea of using an old-fashioned television remote to do anything feels distinctly 2005. That doesn’t mean it’s not a valid way to control the lights at home, and [Atakan] is here to show us how it’s done.

To the experienced electronics maker, this is yesterday’s jam, but [Atakan] goes to great lengths to hash out the whole process from start to finish, from building the circuitry to switch the lights through to the code necessary to make a PIC do your bidding. It’s …read more

A Remote Controlled Air-Plane

Posted on by

The Air Hogs Sky Shark was a free-flying model airplane powered by compressed air. When it was released in the late ’90s, it was a fairly innovative toy featuring a strikingly novel compressed air engine made entirely out of injection molded plastic. Sales of these model planes took off, and landed on the neighbor’s roof, never to be seen again.

A few weeks ago, [Tom Stanton] revisited this novel little air-powered motor by creating his own 3D printed copy. Yes, it worked, and yes, it’s a very impressive 3D print. That build was just on a workbench, though, and to …read more

Junkyard RC Conversion Looks Like Mad Max Extra

Posted on by

Over the years we’ve noticed that there is a subset of hackers out there who like to turn real life vehicles into remote controlled cars. These vehicles are generally destroyed in short order, either by taking ridiculous jumps, or just smashing them into stuff until there’s nothing left. In truth that’s probably what most of us would do if we had access to a full size RC car, so no complaints there.

As a rule, the donor vehicles for these conversions are usually older and cheap. That only makes sense, why spend a lot of money on a vehicle you …read more

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
