Goce, Heather and I (Robert Wray) are heading to SEMA this week. Help us! [LIST][*]Tell us what you want you want to know more about. We will be blogging and shooting lots of HD video.

Has anyone looked into acquiring the HP Touchsmart software and integrating it into a car PC system? And if so is the software compatible with other touch screens?:peep:

A very common topic on the Mp3Car Forums is getting rid of strange audio noise (typically synchronous with the rev of your engine); an odd humming or whining sound. This is generally caused from using multiple ground points in your setup. Because these points are connected to a common ground but from different locations, unsteady or irregular voltage may occur. We can separate the grounds from each other by using a Ground Loop Isolator.



Here is an old one from the archives-

ground loopForum member Gip shows us how the poor man constructs his own Ground Loop Isolator. He uses two transformers removed from a couple of old 56k modems, an RCA adapter and some breadboard. Put it all together and viola... no more audio noise. Originally posted as a means to "remove power supply noise from audio". See more pictures and a full explanation on the thread.

Do you 3d viewfind yourself parking in tight spots all too often? Please don't scratch your bumper trying to fit into that tiny space. To help us carputer users, Robby_BMW has developed a USB interface for aftermarket parking sensor kits. These kits use ultra-sonic sensors which would normally report back to an LED or LCD to indicate the distance between your bumper and whatever else. Robby's interface uses a PIC 18F2550 microcontroller on a custom PCB to send the information to your computer. The device is recognized as a Plug & Play HID. It works as a wired or wireless connection. I suggest you read up on the technicals for customization options as there are limitations depending on your setup. This interface is device specific. Software is available with a multi-lingual Configuration tool. There are also plug-ins for RoadRunner and Centrafuse .

If you like Mythbusters on the Discovery channel, you may want to check out Beyond Productions' new show, Prototype this! tonight at 10. You might even catch a glimpse of our very own Carnetix P1900. These geeks put together all kinds of projects like a Mind controlled car, Boxing robots, Six legged all-terrain vehicle, and a Water slide simulator. This is the first part of a 13 episode season. If you guys are familiar with Defcon, badge designer Joe Grand is part of the cast along with 3 other guys from various technical backgrounds. Be sure to check it out tonight 10 e/p on the Discovery Channel, keep your eyes peeled for the CNX p1900 too!

Why is this the ultimate bench test? I got to sit outside with 70 degree fall weather in the Boston Commons – On a bench; Ahhhh.

For those of you who are regular readers of our blog, I promise we will get back to more car computing content soon. We are one of the few people in the country who have active wimax hardware so there is almost a sense of duty that has set in.
Verizon - 3 tests in a row from using Speekeasy's andwidth test tool


Xohm 3 tests in a row from using Speekeasy's andwidth test tool


Talk about this post in our wimax forums.

As promised we tested Xohm in Boston on Wednesday.

A hex on the skeptics!

Wimax’s black magic is prevalent and resilient in more places than just Baltimore even at 65mph! With a name like Mp3car, we have to test this stuff in our cars...
Below are the results of an in car “driving” test from Boston Logan airport to Weymouth. Keep in mind that Xohm is not officially active in Boston and the network is still in test mode.
Xohm did not work on the runway or inside the airport because they probably don’t have any towers there yet or they are down for upgrades. Xohm DID work at high speeds on the Runway at Baltimore’s BWI so it was not a structure or plane interference issue.

We started driving south away from the BOS airport and before we hit the toll I was getting 2.5 MBPS on my speed test results. The testing didn’t quite finish before we went in the tunnel. So I kept testing all the way to Weymouth. Coverage was patchy, but when it worked, it really worked. Bandwidth speed tests were impressive despite driving at 50-65 mph.
On the maps below you can see a little white man. These men were automatically rendered on my Google map by Xohm’s Location detection feature. They were generally accurate within about 1000ft.

I will write more tomorrow and throughout the weekend on Xohm’s Location Based Services (LBS) and features. For you Boston locals I plan to do speed tests in 3-4 other areas of the city while I am here.

Talk about this in our Wimax Forums.
UPDATE:
Boston College High School. 2.221 MBPS down 604kbs Up 3.47 PM Thursday, OCT 9

i am selling carpc, with GPS,DVD,Internet,....
