Vizio S3821 2.1 Soundbar Review: Packs a Punch for the Price

I recently had the opportunity to swap out the 5.1 audio system in my living room with the Vizio S3821 2.1 soundbar and subwoofer. This slimline sound system is a great way to add high quality sound to your flat-screen TV without having to run a bunch of wires, and without breaking the bank.

The speaker bar itself measures 38″ (w) x 3.6″ (h) x 2.9″ (D) and fits nicely beneath or in front of most flat screen TVs 40″ diagonal and up. It also comes with mounting hardware should you choose to wall mount it instead. In addition to the soundbar, the system includes a small powered subwoofer (13.5″ (w) x 11″ (h) x 6″ (d)) that you can set anywhere you have a power outlet, thanks to a wireless connection to the main speaker.

Connecting the Vizio soundbar is simple. The easiest way to go is to connect its optical or coax digital input to the corresponding output on your TV set. Most modern sets can do the switching between multiple video inputs, then output audio using one of these methods. This way, you avoid the need for switching inputs on the soundbar. That said, it does offer a total of six inputs, including one each of digital optical, digital coax, RCA analog stereo, 3.5mm mini and USB. The fifth input is a wireless connection for Bluetooth devices. Vizio is kind enough to include optical, coax and RCA cables in the box. Inputs can be switched from the remote control, and are displayed on the face of the soundbar using a set of small white LEDs. In my case, I only connected a single optical cable to my TV and paired my mobile devices.

Speaking of Bluetooth devices, this thing was a dream when paired with my iPhone and HTC One. Music quality was exceptional, providing room-filling sound in my 400+ sq. ft. living room, and a wide soundstage that bested the dedicated 5.1 speakers I currently have. Its included remote control can also be used to operate your Bluetooth device, including play, pause and track controls.

But the music capabilities of the Vizio 2.1 soundbar are really a bonus. The main use case for this system is for watching movies and television programs, and playing video games, and I’m happy to say it handled all of these with aplomb. I found the sound quality of the soundbar to be quite satisfying, with good dynamic range, and imperceptible distortion even when pushed to the highest volume level it could push out.

The 6″ powered subwoofer isn’t going to make your walls shake the way they do in a theater, but it does offer enough punch to get the point across. Oddly enough, Vizio doesn’t provide wattage specs for the speakers – they only say that frequency response ranges from 50Hz to 19KHz, and that the system can push out 100dB of sound at 1 meter with less than 1% THD.

Top volume for the system isn’t going to make your eardrums bleed, but it is plentiful – more than enough to wake the neighbors and fill a large living space, and its really nice that there’s no crackling or unexpected vibration at peak volume levels. When using the system, I did find that turning on DTS TruSurround offered the best overall experience, as it created an extremely large and open soundstage, and did an admirable job providing a sense of surround when watching movies and playing games. That said, you won’t be able to pinpoint sound locations like you could with dedicated speakers for each surround channel. The system also supports DTS TruVolume for keeping volume levels consistent. Personally, I’m not a fan of messing with dynamic range in that way, so I left that off.

Overall, I was more than pleased with the quality of the Vizio S3821 soundbar. It’s more than sufficient for anyone looking to add high quality sound to their living room without breaking the bank, and works well for a wide variety of content. It’s priced at just $179.99(USD) and can be purchased direct from Vizio, though you can find it over at Amazon for about $20 less.

Empire Steampunk Speakers: For Dapper Audiophiles Only

There’s something that continues to intrigue me about Steampunk style. I think it’s the idea that technology could be driven by steam power instead of electricity. And while these speakers aren’t actually driven by steam, they’re still pretty amazing.

This pair of Empire Steam speakers was handmade by Airhammer Industries. Each octagonal cabinet is made from MDF with a copper veneer, copper edging, and brass and bronze details. They’re extremely substantial, as is evidenced by the large 1.5″ thick granite top on each one, and an approximate weight of 125 pounds per speaker.

Inside of each 36-inch-tall speaker is a pair of Vifa 1″ silk dome tweeters, a 5″ Pyle midrange, and a 15″ Goldwood downward-firing subwoofer for cranking out the bass while you watch The League of Extraordinary Gentlemen on your steam-powered television. Maximum power per speaker is 400 Watts RMS @ 8 ohms.

While these speakers are glorious, they’re not exactly cheap. All of this craftsmanship and audio tech will set you back a whopping $12,600 (USD) for the pair. I wonder how much they would have cost back in the 19th century?

Stack Printer Concept is Its Own Paper Tray

I’m more interested about 3D printers than ink printers these days, but I couldn’t pass up sharing the Stack printer with you. It’s a concept by industrial designer Mugi Yamamoto that’s meant to save space and gives you a better idea of how much work it has done. Instead of a paper tray, it sucks up paper from its bottom then spits out printed pages on its top.

Yamamoto designed the Stack for his diploma project at ECAL. According to Wired, Stack is smaller than an A3 sheet of paper and is just about 2″ tall. It owes its compact size partly due to having no paper tray. In theory, it’s also easier to add more blank paper to Stack’s uhm, stack. I wonder if it’s okay to lift the device up and move it about while it’s printing. Aside from its practical features, Yamamoto also made Stack as a counterpoint to the “over-engineered” design of some gadgets.

Yamamoto already has a working prototype of Stack and is interested in mass producing the printer. He should make a scanner and photocopier that work like this too.

Philips Hue Lightstrips and Bloom: An Eyes-on Review

A few months back, I outfitted my man-cave/media room with Philips Hue LED light bulbs in all of my recessed ceiling fixtures. This has given me the ability to set different moods in the room, and even automatically dim the lights to a warm, theater-like quality when I want to go watch a movie. However, up until now, the Hue ecosystem was pretty much limited to reflector bulbs. Recently, Philips released their first “Friends of Hue” products, which include the Hue Lightstrips and the now-Hue compatible Bloom lamp. Philips was kind enough to put both of these in my hands so I could see how well they worked alongside my other Hue lights.

philips hue lightstrips bloom

I first cracked open the Hue Lightstrips, which allow you to add colorful accent lighting under furniture, on top of shelves or in other locations where you can conceal a strip of lights. Each Lightstrip is a 2-meter-long (~6.56 feet) bendy strip covered with LEDs about every 1-1/2 inches. The strip itself is covered with a flexible, optically transparent cover to protect the delicate LEDs and circuitry.

Each strip is connected to a cord which has a small wireless receiver pack and a small power adapter on the end. The strips can be cut at pre-marked locations about every 4 inches, but there’s no way to reconnect sections once cut, so you need to be careful to only trim off sections of LEDs you don’t ever plan to use again. Once you pick a location to install your Lightstrips, you can stick them in place using the sticky 3M adhesive on the back of the strip, or for less permanent installations, you can just lay the Lightstrip in place, and use cord clips to hold it in position.

One thing to keep in mind is that the Lightstrips are best used in straight lines or very large curves. It’s basically impossible to bend them into sharp angles, so if you want to achieve that sort of effect, you’ll need to buy multiple Lightstrips and cut them to length. I’m hoping that down the road Philips offers some sort of angle connectors so you can splice cut segments to each other.

The strip itself produces bright and saturated accent colors, though it can’t really achieve the pastels and whites of Hue light bulbs. That’s just fine by me, since these are really meant to be accent lights. Each LED can produce a range of 16 million colors and is quite bright.

Once plugged in, the Lightstrips work like any other Hue bulb. They can be easily paired with the base station using the Hue app, and also worked brilliantly with the LivingColors remote I have from an older Philips lamp I have in my room. Of course, it’s also compatible with the Hue API and 3rd party Hue apps too. Hue also works with IFTTT recipes, so you can do things like trigger your lights to change colors when you receive an email from a specific person, or based on the weather forecast.

In my case, I ended up installing the Lightstrips under the front lip of my custom arcade cabinet, adding bright and colorful illumination to the artwork on the base of the cabinet. I suppose if I had more strips, I would have put underside lighting on my couch, but a single Lightstrip wasn’t enough for my sectional.

Next up is the Bloom lamp. This lamp has actually been around for a little while as a LivingColors product, but is now being sold as a member of the Hue family, so it works out of the box with the Hue bridge and apps with no fiddling about. It’s also about $10 cheaper, since there’s no LivingColors remote included with the Hue version. The 120-lumen Hue Bloom is a 16 million color RGB accent light, delivering punchy colors, and is great as a wall wash lamp.

It was hard to tell, but the lamp appears to be made from metal, so it’s substantial for its size. This little 4-inch diameter lamp is bright enough to splash colors which can be seen clearly from the back of my 30-foot-long basement media room.

I placed the lamp behind one of my media towers, but it would also work great behind a television to increase perceived contrast, or just to make it look cool, like I’m doing with my older LivingColors Gen. 2 lamp.

Here are a few pics of my room, with all of my Hue lamps in action:

Overall, I’m impressed with everything about the Hue ecosystem, and am happy that Philips is starting to add new lamps to the series. Lightstrips can really add colorful accent lighting behind pictures, under sofas, and under cabinets – though their inability to be bent at sharp angles is a little limiting.

The complete Hue lineup is available from Apple Store locations. Lightstrips sell for $89.95(USD), and the Bloom lamp sells for $79.95. Keep in mind that all Hue products require the Hue bridge, which is only available in the $199.95 Hue starter kit, which also include three Hue bulbs.

HTC One Sees Red at Sprint

I’m a big fan of the HTC One. It’s one of the best Android smartphones made to date, combining an awesome display, great camera, a fast CPU and GPU, and excellent build quality. But if you buy one, you’ve been able to get it in bare aluminum (or a hard to find black). Now, thanks to a deal with Sprint, the HTC One is now available in a lovely shade of red.

And they haven’t just painted the case red or snapped on a plastic back. This is still an all metal case, just like the original HTC One. Sprint is offering the exclusive new Red HTC One at this link for $199.99(USD) – and if you buy one by August 29th, you’ll get a second HTC One free. Naturally, the deal assumes you’ll sign up for a two-year phone contract for each device.

If red isn’t your thing, rumor has it that Verizon will be outing an exclusive blue version by the end of the month as well.

Haptix 3D Multitouch Controller: You Are the Mouse

A few years ago we took a look at Pranav Mistry’s Mouseless, a prototype for a camera-based pointing device. Now, a startup called Haptix Touch is raising money on Kickstarter for a very similar – and possibly better – product. It’s called the Haptix, and I would love to trade my mouse for it.

haptix 3d multitouch controller

Haptix turns any surface into a multitouch interface. It connects to computers via USB and uses two CMOS image sensors and a patent-pending algorithm. Like Mouseless, Haptix also has an infrared tracking mode for low light situations. In my brief chat with Haptix Touch Co-Founder Darren Lim, he said that the Haptix can track and assign different functions to up to 10 objects. For example, you can map your index finger to the mouse cursor, your thumb for left click, and so on. You can even tell it to ignore an object. This means you can use your table or desk as a touchpad, use a pen to draw or sketch in an image editing program or  – my favorite – use your keyboard as your mouse.

Pledge at least $65 (USD) on Kickstarter to get a Haptix controller as a reward. The current version of Haptix works with Windows 8 and other touch-optimized programs out of the box. Lim said it will support Android and OS X devices by the time it’s commercially available, which is hopefully near the end of 2013. Lim also said they will release the developer API and dev kits after Haptix is launched.
