Adapting the Nexus 7 for a double DIN car dashboard opening

making-nexus-7-fit-in-double-DIN-dashboard

It turns out that the Nexus 7 Android tablet is the perfect size to fit in a double DIN opening. DIN is the form factor of a single CD head unit for an automobile. Many models have room for a double DIN, which is defined as 4″ high by 7″ wide. Once [Meta James] figured out that the dashboard bezel for his Subaru framed the Nexus 7 perfectly he set out to fabricate the mounting system for an in-dash tablet installation.

Unlike a lot of these dashboard tablet installs, [James] didn’t need any Bondo, sanding, or painting to get things to look right. Like we mentioned, the bezel is a perfect fit so his alterations are hidden behind the tablet itself. He removed the stock head unit and ordered a DIN adapter kit to get the black bracket plate seen above. He built an acrylic box the same size as a double DIN head unit, then mounted the plates to the sides and a Nexus 7 case to the front. This holds the tablet in firmly, lets him mount the entire assembly using the factory mounting points, and leaves plenty of room for the cabling that connects the device to the car. Since he already had a hands-free phone system he just uses that to amplify the audio fed to it via Bluetooth.

Bubble wrap cure for Nexus 7 speaker distortion

nexus-7-bubble-wrap-fix

[Home Brand Cola] is quite happy with his Nexus 7 with the exception of the built-in speaker. It produces fairly good audio quality until he reaches about 50% volume level. Anything above that produces distortion. He figured out how to fix it using a small piece of bubble wrap.

The eureka moment came when he was using his Nexus 7 and discovered he could fix the distortion by gripping the top and bottom parts of the case strongly between his finger and thumb. This led him to realize that the speaker unit is a bit loose and the unwanted noise is produced when it vibrates against the case. The video after the break shows the fix, which places a strip of bubble wrap (looks to be about 1″ by 3″) on top of that speaker unit. When the case is snapped back together the packing material helps hold everything in place and now he can use his tablet at full volume without any problems. One of the comments on the Reddit thread asks about heat problems with the addition of this plastic. He’s been using it for a few weeks and so far no issues there.

Chromium on the Nexus7

[Hexxeh] is at it again, porting the chromium OS to whatever seems to appear in front of him. This time he’s ported it to the Nexus 7. Last time we saw him, he was raspberry chomping at the pi. The details are very scarce, so we would like to issue this request.

[Hexxeh] we realize you don’t think your every-day-joe would be up to the task of putting chromium on their nexus 7. This is Hackaday however, and we know that at least a few of our readers would LOVE to join you in your efforts and could possibly contribute to your fun. Share some details with us… please.

You can see a video of it in action after the break.

Giving the Nexus 7 HD video recording

As released, the Nexus 7 tablet includes a 1.2 Megapixel front-facing camera. Even though the camera supports taking pictures at a resolution of 1280 x 960, recording video is limited to a paltry 480p resolution. It turns out the inability to record HD 720p video isn’t a hardware limitation; engineers at either Google or Asus simply didn’t bother telling the Nexus 7 how to record in 720p.

[hillbeast] over on the XDA developers forum came up with a very easy fix for this problem that only involves a quick copy and paste job into the media_profiles.xml file.

After the break you can see two videos recorded with [thehillbeast]‘s Nexus 7. The first is a 480p video of a bit of shrubbery and a fence, while the second video is the same scene recorded at 720p. A noticable difference in quality, and a neat hack to give the already awesome Nexus 7 some additional capabilities.

Send your Nexus 7 back… to tighten one screw?

It seems that some of the Nexus 7 models have an assembly issue that makes the bezel uneven with the screen. It’s just in one spot but your shiny new toy shouldn’t have this kind of problem. Of course it comes as no surprise that Google wants you to send it back for service. What is a surprise is that the fix involves tightening just one screw. Now we can’t stand for shipping something round trip when it comes to this low-skill fix. Luckily neither can [Baddspella]. He shows us just how easy it is to repair the Nexus 7 yourself.

The only tools you need are a guitar pick (or other thin plastic prying device) and a very small Phillips screwdriver. Starting at the top of the tablet he uses the plastic pick to pry off the back of the case. This exposes the screws which hold the bezel in place. Find the loose one, and give the screwdriver a turn. Now just snap the back cover in place and you’re done. We’ve embedded the video after the break for your convenience.

It’s super simple…. so don’t be afraid to crack that thing open.
