Looking for the perfect car MP3 player/FM transmitter

I have bought quite a number of car MP3 player/FM transmitters from DealExtreme and other similar websites.


A car MP3 player/FM transmitter is a device that takes a SDHC memory card or a USB memory stick and plugs into the car cigarette lighter socket. It plays the MP3 files stored on the memory card/stick and transmits that as FM signal to be picked up and played by the car stereo.

It is a nifty and convenient device because not all car stereo can play MP3 files, or be able to accept a memory card or stick. Also such a device is very portable. You can simply plug it into any vehicle eg. a company car and it will play all your favorite music.

Other alternatives exist eg. bluetooth, but they are simply not as straightforward and universal as this solution. After all, you'd be hard-pressed to find a car without a cigarette lighter plug.

The perfect car MP3 player/FM transmitter should have the following characteristics/features:

  1. Emits strong FM signal
  2. Remembers last FM frequency used
  3. Remembers last MP3 file played
  4. Remembers position of last MP3 file played
  5. Supports Unicode font on LCD display
  6. Body of memory card should not stick out when plugged in
1 and 3 are pretty much essential for the device to be useful. Unfortunately I have had to throw at least .a few devices away right upon arrival because they were lacking one or both of these features.

2 and 4 are good-to-have features (some may even consider them essential). 2 can be overcome by setting the car stereo to the default frequency, but sometimes you need to change the default frequency on the device because of interference, and having to do that during every cold start gets old after a while.

4 should be quite easy to do (just a little extra memory to store the last play position), but surprisingly I have not seen any device that has this feature! Either there is some unknown technical barrier to implementing this feature, or Chinese manufacturers are .too stingy to spend a few more cents to do so.

5 is a nice-to-have, since none of my Mandarin songs have their ID3 displayed correctly. On the other hand, this is understandable because it will probably add a lot to the production cost to embed a Unicode font into such a tiny device.

6 is simply a design issue. Half of the devices have it right, others have the memory card sticking out so badly I wonder what the designers were thinking.

I have yet to find my perfect car MP3 player/FM transmitter. I have bought at least a dozen such devices now, and none of them have all of 1,2,3 implemented, not to mention the others. The local Chinese OEM devices sold in Oz stores are not .much better.

Anyway, if you know of the perfect car MP3 player/FM transmitter, please leave me a comment. I am willing to pay a premium for such a device, but I am tired of buying one device after another and being disappointed over and over again...

Adding "Stereo Mixer" to Windows 7 with Conexant sound card

This procedure worked for my laptop (Thinkpad E530) with a Conexant 20671 sound card, but I suspect it will work for other sound cards in the Conexant family. I was playing with CamStudio to do a video capture of a Flash-based cartoon so that I can put it on the WDTV media player and play it on the big screen in the living room for my kids. The video capture worked brilliantly, but to do a sound capture, I needed to do some hacking. Apparently, there was this recording device called "Stereo Mixer" that was pretty standard in the Windows XP days. This allowed you to capture whatever was played to the speaker in all its digital glory. Then under pressure from various organizations on the dark side of the force, Microsoft and soundcard makers starting disabling this wonderful feature from Windows Vista onwards. So after much Googling around, I found out that for most sound cards, the hardware feature is still there, just not enabled on the software side. Unfortunately, to

Hacking a USB-C to slim tip adapter cable to charge the Thinkpad T450s

This hack is inspired by this post . A year ago, I bought an adapter cable for my wife's Thinkpad X1 Carbon (2nd Gen) that allows her to power her laptop with a 60W-capable portable battery (20V x 3A). A USB-C cable goes from the battery into the adapter, which converts it to the slim tip output required by the laptop. Everything works out of the box, so I didn't give much thought about it. Recently, I decided to buy a similar cable for my Thinkpad T450s. I know technically it should work because the T450s can go as low as 45W (20V x 2.25A) in terms of charging (though I have the 65W charger - 20V x 3.25A).  I went with another adapter cable because it was cheaper and also I prefer the single cable design. So imagine my surprise when the cable came and I plugged it into my laptop and it didn't work! The power manager just cycle in and out of charging mode before giving up with an error message saying there is not enough power. After much research and reading the Thinkwiki

Using Google Dashboard to manage your Android device backup

I used to use AppBrain/Fast Web Install to keep track of which apps I have installed on my phone, and to make it easier to reinstall those apps when the phone gets wiped or replaced. But AppBrain had been going down the tubes, and Fast Web Install had always been a hit-and-miss affair. Android's own "backup to the cloud" system had previously been even more unusable. There isn't a place where you can see what has been backed up. And when you setup a new phone with your Google account, you just have to wait and pray that your favorite apps will be restored to the phone. Typically all the stars have to be aligned just right for this to happen. More often than not, after waiting for an hour or so and nothing happens, you just curse under your breath and proceed to install your favorites apps manually via the Play Store. But I just looked again recently and was pleasantly surprised that things are much more civilized now. Firstly there is a place now where you can loo
