High-Effort Streaming Remote For Low-Effort Bingeing

March 10, 2018 by Dan Maloney 7 Comments

There’s no limit to the amount of work some people will put into avoiding work. For instance, why bother to get up from your YouTube-induced vegetative state to adjust the volume when you can design and build a remote to do it for you?

Loath to interrupt his PC streaming binge sessions, [miroslavus] decided to take matters into his own hands. When a commercially available wireless keyboard proved simultaneously overkill for the job and comically non-ergonomic, he decided to build a custom streaming remote. His recent microswitch encoder is prominently featured and provides scrolling control for volume and menu functions, and dedicated buttons are provided for play controls. The device reconfigures at the click of a switch to support Netflix, which like YouTube is controlled by sending keystrokes to the PC through a matching receiver. It’s a really thoughtful design, and we’re sure the effort [miroslavus] put into this will be well worth the dozens of calories it’ll save in the coming years.

A 3D-printed DIY remote is neat, but don’t forget that printing can also save a dog-chewed remote and win the Repairs You Can Print contest.

Video Streaming Like Your Raspberry Pi Depended On It

September 12, 2017 by Lewin Day 23 Comments

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 I set sail for the nearest search engine and begun researching my problem.

My first approach to the challenge was the venerable VLC Media Player. Initial experiments were sadly fraught with issues. Getting the software to recognize the webcam plugged into my Pi Zero took forever, and when I did get eventually get the stream up and running, it was far too laggy to be useful. Streaming over WiFi and waving my hands in front of the camera showed I had a delay of at least two or three seconds. While I could have possibly optimized it further, I decided to move on and try to find something a little more lightweight.

Save Your Thumbs With This Netflix Password Sender

August 29, 2017 by Dan Maloney 22 Comments

Chances are anyone who has an entry-level to mid-range smart TV knows that setting them up with your streaming account credentials is a royal pain. Akin to the days of texting on a flip phone, using the number pad or arrow keys to compose your user name and password seems to take forever. So why not avoid the issue with this automated Netflix logger-inner?

As if the initial setup wasn’t bad enough, when [krucho5]’s LG smart TV started asking for his Netflix credentials every few days, he knew something needed to be done. An Arduino to send “keystrokes” was the obvious solution, but when initial attempts to spoof the HID on the set proved fruitless, [krucho5] turned to the IR remote interface. He used an IR receiver module to capture the codes sent while entering user name and password, and an IR LED plays it back anytime the TV ask for it. The video below shows how much easier it is now, and the method should work just fine for any other online service accounts.

We like [krucho5]’s build, but the fit and finish are a little rough. Perhaps slipping them into a pair of Netflix-enabled socks would be a nice touch?

Live Stream To YouTube By Pointing A Box And Pressing A Button

August 18, 2017 by Donald Papp 12 Comments

YouTube has the ability to do live streaming, but [Tinkernut] felt that the process could be much more straightforward. From this desire to streamline was born the Raspberry Pi based YouTube live streaming camera. It consists of a Raspberry Pi with some supporting hardware and it has one job: to make live streaming as simple as pointing a box and pressing a button. The hardware is mostly off-the-shelf, and once all the configuration is done the unit provides a simple touchscreen based interface to preview, broadcast live, and shut down. The only thing missing is a 3D printed enclosure, which [Tinkernut] says is in the works.

Getting all the software configured and working was surprisingly complex. Theoretically only a handful of software packages and functionality are needed, but there were all manner of gotchas and tweaks required to get everything to play nice and work correctly. Happily, [Tinkernut] has documented the entire process so others can benefit. The only thing the Pi is missing is a DIY onboard LED lighting and flash module.

Bring Saturday Mornings Back To Life With This Cartoon Server

February 23, 2017 by Dan Maloney 28 Comments

It was an American ritual for over four decades: wake up early on Saturday morning, prepare a bowl of sugar, and occupy the couch for four glorious hours of cartoons. The only interruptions came when the least-significant sibling had to be commanded to get up to change the channel to one of the two other networks, or when your mom decided to vacuum the TV room. It was a beautiful ritual, but now it’s gone.

Or is it? If you really want to recapture your misspent youth, you can try this Raspberry Pi multi-channel cartoon server with retro TV display. [FozzTexx] started with a yard sale 13″ Zenith set, which languished in his shop for want of a mission. When he found a four-channel video modulator, he knew he had the makings of the full channel-changing Saturday morning experience.

Four Raspberry Pis were configured to serve up four separate streams of cartoons from his Plex server, and after a late Friday night of hacking the whole thing together, each stream was ready to go live at 7:00 AM on Saturday. [FozzTexx] thought of everything — from the pre-“broadcast day” test pattern to actual commercials spliced into the cartoons to the static between the channels, it’s all there in low-definition glory. He even printed up faux TV Guide pages! You can watch a brief demo on [FozzTexx]’ Twitter feed, or you can watch the entire 2-hour Periscope feed if you’re feeling nostalgic.

[FozzTexx] chose UHF channels for his “stations,” so if you want to replicate this build it may pay to bone up on analog TV tuner basics. Or if it’s just the retro look you’re going for, this custom case inspired by a 40s TV might be nice to check out.

Raspberry Pi Spies On… Err… Monitors Baby

November 12, 2016 by Dan Maloney 7 Comments

“Quick! We’re having a baby and we need a baby monitor!” Rather than run to the local big box and plunk down cash for an off-the-shelf solution, any self-respecting hacker would rise to the challenge and hit the shop to build something like this live streaming eye-in-the-sky baby camera. Right?

At least that’s how [Antibore] handled the situation, and the results are pretty good. He designed his build around an old Raspberry Pi 2 that was hanging around. That required a WiFi adapter, and since he wanted video and audio he needed a camera and mic. The first USB mic had a nice compact design but didn’t perform well, so a gutted gooseneck mic soldered right to the USB connector joined the design spec. A camera module, cell-phone quick charge battery bank, and a 3D printed case round out the BOM. A knitted cozy to keep it looking warm and fuzzy was provided by the mother-to-be — although we think it looks a little like [Mike Wazowski].

This self-contained unit will work anywhere it has access to a WiFi network. Mounted on the baby carrier, it’ll provide a live stream to any browser and provide the new parents with a little peace of mind.

There are a lot of baby monitors on the market, some of them terrible and in need of a rebuild. Kudos to [Antibore] for deciding to roll his own custom solution and for getting it done before the blessed event. Now how about painting that nursery?

Raspberry Pi Radio Streaming Service Guts Yamaha Shelf System

September 9, 2016 by James Hobson 9 Comments

There are dozens — dozens! — of options to meet your music and streaming needs these days. Looking to make something of his own that retains that 90’s vibe of having a dedicated stereo system but with modern wireless integration, [thk4711] turned an old Yamaha hifi into a Raspberry Pi streaming client.

As far as the case goes, a few modifications allowed [thk4711] to use all of the existing buttons, and a quick-swap of the back-plate and screen gave him a better enclosure than one he could fabricate himself. The power supply proved to be the most difficult part of the project due in part to some “digital noise” interference between the digital and analog components while they were wired to a common ground. This was solved by implementing two transformers, a LM2596 voltage regulator and a LT1084 low-noise power supply to smooth things out.

The Raspberry Pi 2-centered device supports internet radio, Spotify connect, Airplay, USB and auxiliary inputs.
