Elliott C. Back: Internet & Technology

If you aren’t familiar with Hidden Radio & BlueTooth Speaker by John VDN + Vitor Santa Maria, it is one of the more popular Kickstarter projects, having $938,771 on a $125,000 goal. Their plan was to create “the simplest, most powerful radio and wireless speaker for iPhone + iPad ever.” In this review, we’ll see if the bluetooth behemoth lives up to the hype!

Unboxing

The packing for HiddenRadio is immaculate, iPhone style, with a certain simplicity that seems to be directly ripped off from an old-school iPod box. There’s no Microsoft-esque list of system requirements or tacky stickers. You’d feel proud wrapping one of the Hidden Radios up for a gift. There is a subtle panel of use-cases on the back, while the other three sides are product shots:

I opened it up; inside you get a few accessories:

• A USB mini cable for charging
• An audio mini-jack FM radio antenna cable
• An audio mini-jack cable to connect to your Sony Walkman or … whatever
• A microfiber drawstring dust pouch

Also, there’s the unit itself. A rounded grey (hey dude, I order silver!) cylinder, it looks sleek and is shorter than a beer bottle, and slightly smaller than your palm in diameter. They’re cute looking little devices, and it’s the design concept rather than the sound engineering, I believe, which got them their first million dollars in Kickstarter sales:

Build & Sound Quality

So how does it sound? I received two units, and they are slightly different. Both units exhibit a mediocre range with very little bass when placed on a flat surface. Treble is also attenuated, so you end up having to set EQ on your iPhone to “Rock” or a similar setting to get a response that sounds similar to the song you’re trying to listen to. When held in the air, the speaker sounds quite a lot better. Also, the volume control doesn’t work terribly well. If you set your iPhone to 100% output (no eq), the Hidden Radio will actually distort. So instead of using the beautiful twist feature to control volume, you’ll most likely leave your HiddenRadio 80% open and control volume from your iPhone. More than 80% and the sound quality again degrades.

Another sound quality issue I encountered was a constant buzzing from the unit–but only one of them. The other HiddenRadio didn’t have the same poor circuitry causing the buzz. Fortunately, it seems to be worst only when turned on, or in front of a monitor, and not playing sound. Once it locks onto a bluetooth signal, the buzz amplitude is reduced or eliminated–but you might notice it on a quiet song!

As for the build quality, it’s not good enough. I’m not sure why you twist the device left to open, which is an awkward motion for right-handers. The device feels plastic, and doesn’t have enough weight in the base to stick to the surfaces you place it on, so actually turning it on usually takes two hands: one to stabilize it, the other to twist it open. This defaults the main point of Hidden Radio: the gorgeous twits-to-open feature. Both of my units suffer from superficial defects: the first has paint already chipping off the plastic around the base ring, while the second one’s grille has a permanent dimple. See if you can spot it:

Hidden Radio definitely needs to improve their quality assurance process before selling to the mainstream customer. Another example–one unit came with some charge, while the other (better) unit was entirely uncharged:

The base also needs a few more pounds of weight so that it sticks. Right now, I either need to apply more downwards force than it would take to fire an NYPD glock, or pick the thing up in two hands to turn it on.

Ports

The Hidden Radio has all of its input ports on the bottom–you charge it through a mini-USB cable that plugs in on the base. You can also either give it direct audio input or FM antenna through a minijack on the base. There’s also a bluetooth/direct input/FM radio switch and channel picker to control the modes there:

Other Reviews

You can check out their KickStarter comments page which includes mostly negative feedback. The founders appear to be removing anything but positive comments from their Facebook page. Here are a few comments from Kickstarter:

• I bought a five pack to give as gifts, unfortunately, the one I opened to try (only after hearing all the negative reviews) it sounds TERRIBLE. At low volume it is so distorted that I cannot bear to listen.
• I received two units, both look very nice. But the first one has a lot of white noise in the background while charging via USB, the second one’s volume control is out of order.
• Well add one more backer with the frustrating automatic shut-off between two and three minutes. This only happens in wireless and wired mode though. In FM mode the HR stays on.
• Everything worked flawlessly out of the box. Simple, easy to use, well made and it really does sound good.
• Frankly I have to say that the sound quality is horrible yet especially at the max volume. Voice being distorted and sound stage is bad.
• First of all, this thing is solid. It’s surprisingly heavy, which is nice because with the “no movement” pad on the bottom it has no problem staying in place on a variety of surfaces (I tested glass, wood, and laminate). Secondly, the range is amazing. I have a small 3/2 house and I can sit it in one corner of the house and play music in the other corner. That’s going through 3 walls, one of which is insulated. Finally, the volume is loud, surprisingly loud.

TechHive also gave it a big “meh” review.

My Take?

This is HiddenRadio v1, which for $115/unit, you get a gorgeous bluetooth speaker you can plug into your bedroom and kitchen and rock out while you read, cook, do chores, etc. The sound quality is acceptable, if you know how to goose the settings, and hopefully the Hidden Radios will survive the test of time. I’d give it a 3/5, for now, until they improve the frequency response of the units. Bluetooth is also a bit gimmicky, and quite static-prone.

I don’t care about direct minijack access or FM radio; just give me an amazing bluetooth speaker with great batter life, a bigger speaker or more speakers for better sound, and a twist-to-the-right to open, and I’d happily give you 5/5!

In this post, I’ll be reviewing a brand new Synology DiskStation DS1511+ NAS equipped with five Hitachi Deskstar 2TB 5K3000 drives configured in RAID5. For comparison, I’ve also written about the Gen 1 Drobo’s performance as a NAS before (it tops out around 20MB/s), and own two of them at home. While the Drobos allow you to build mix-and-match RAID arrays, they are slow, take forever to rebuild, noisy, and hot. I am hoping the DS1511+ will remedy all of these issues.

Read more about the DS1511+ specs here

Network Base Configuration

The Synology NAS is using default MTU of 1500, connected to a Gigabit Ethernet Switch on LAN2. Testing with iperf shows a good gigabit connection between my PC and the NAS of around 885Mb/s:

Big_Bug> iperf -s
————————————————————
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
————————————————————
[ ID] Interval Transfer Bandwidth
[ 7] 0.0-20.0 sec 2.05 GBytes 882 Mbits/sec
[ 6] 0.0-30.0 sec 3.09 GBytes 885 Mbits/sec

In megabytes per second, we can transfer 110.625 MB/s. As you will see, this is actually slightly lower than the performance of the RAID array.

The Hard Drives

How fast are the triple-platter 2TB deskstar 5K3000s in RAID5? It can do a very reasonable 125 MB/s in unbuffered pure-disk performance:

Big_Bug> hdparm -t /dev/sda
Timing buffered disk reads: 374 MB in 3.01 seconds = 124.22 MB/sec

Benchmarking File Copy from Windows

To test how fast I can transfer from my PC to the NAS, I’ve created a 4GB binary file:

C:\Users\Elliott Bäck\Desktop>ls -l test.file
-rw-rw-rw- 1 Elliott Bäck 0 4693544330 2011-04-19 20:00 test.file

Copying this file in Windows 7’s explorer took just 50.5 seconds. Doing the math, this gives us an average write rate of 88.63 MB/s. How fast can we copy it back? It took 71.6 seconds, for an average read rate of 62.51 MB/s. Both of these number are going to be constrained by how fast my desktop PC’s Intel SSD can read/write. I also tested using Java and writing a RandomAccessFile with a ByteBuffer, which achieved 95MB/s write and 97MB/s read on a 1GB file.

Reliability & Temperature

You just need to open up the storage manager on the Synology DS1511+ NAS to see what a beauty it is, giving you a full SMART status readout on all your physical drives, as well as their temperatures. Even after running through my benchmarking, the drives were only 34^° C warm:

Conclusions

At nearly $900 for the NAS itself without drives, it’s pricey. But plugged into a Gigabit ethernet, the DS1511+ from Synology is also fast, cool, and quiet; the three things you want most from a NAS. Featurewise, it has a glorious UI, media servers built in (which I don’t use) and expandibility from 5 to a maximum of 15 drives. I anticipate phasing out my Drobos, with their proprietary technology, for the Synology NAS, which runs on open-source plain-vanilla linux.

This post is a followup to the quite dated tutorial I wrote in 2005, called How to rip a DVD: A Tutorial. At that time, DVD decrypter and AutoGK were the tools of choice, but they’ve been supplanted as technology has improved by more user-friendly, automatic programs.

As of 2011, I would recommend using Handbrake, an open-source multithreaded and cross-platform ripper which works on Windows and Apple Mac OS both!

Step 1: Download & Install

Please download and install Handbrake to get started. At about 6MB, it shouldn’t take more than a minute.

Step 2: Launch the DVD Ripper

Put in your DVD and launch Handbrake. You should be greeted with an informative screen similar to the following:

By default, nothing is selected yet. There are a few options you can set, such as your preferred subtitle capture language and dubbing language preferences. I prefer the movies in original audio with English subs.

Step 3: Select the Source

I just popped in a Coen Brothers DVD, so when I click on the “Source” dropdown, it shows up there right away. Unfortunately, you can’t directly rip a commercial DVD this way. You need to dump it to disk with DVD Decrypter, after which you can select a DVD rip saved to a folder on your harddrive:

After some time (“Processing Title: 1 of 15…”) you will see the main screen populated with information. If you get stuck on the “processing title” bit, remember you need to open a folder you saved from DVD Decrypter (the decryption will take 20-30 minutes for a feature film).

Step 4: Choose a Title

Titles are like the chapters of a DVD. Usually there will be a single long title that contains the movie, like the 1 hr, 56 minute “Title 1″ I am selecting:

Step 5: Choose Output Settings

You have a lot to choose from. You can pick one of the Handbrake presets for iPod/iTouch/iPad, or customize one of your own. I’m going to use the “High Profile” setting to watch on my PC, but override the target file size to 2 CDs, or 1400 MB:

Step 6: Encode the video

Just click the “Start” button to kick things off, or “preview” to make sure you’re OK with the quality:

It’s going to take me about 52 minutes to encode this; on my i7 with 4 cores x2 hyperthreading, CPU usage is at 100%.

Finally…

If anything goes wrong, there’s an entire Handbrake community who can help you out. Why don’t you start by looking at their How To Request Support for HandBrake thread?
