The low-pass filter didn’t do the job. There must be a coupling issue between the CD player and the car audio. With the current CD player, I can crank the volume all the way up and just barely hear it on the car audio, if the signal from the RF box is cut. [...]

The AUX in Jack I added to my car stereo works great with one exception, when the CD player isn’t playing you can hear static, or whatever the radio is tuned to.
I’m not the only one with this problem, but I’m having trouble finding the other sites…
What I want is to allow the voltage from [...]

An article on AC vs DC on Treehugger.com sparked some interesting comments…
This comment especially caught my attention. In it, the commenter mdpd looks at some basic electrical calculations to show why we use high voltage AC to distribute current around the nation.
The short answer is this: We transmit electricity at high-voltages because [...]

I put together plans for a new project, an In-Car CD Player Holder. It was put together using what I had on hand. Most of the dimensions are not critical. The holder rests between the passenger seat and the center console. There is a tight enough fit that the seat holds it in place. [...]

The Gadgeteer is becomming my favorite website for new gadgets and gear. Julie takes the time to write most of her own reviews and she looks at current products and accessories.
I found this site when I was looking at the OQO Model 02 and found a review on The Gadgeteer.
I don’t know why I [...]

Here is a photo that details the circuit board traces that I connected my wires to.
Click on the photo and go to my Flickr. I added a note to the photo, so you can find the traces.
See more photos at my Flickr. I think I have a few that are not on this [...]

I have a cool little CD player that I picked up at Goodwill for $3.00. I’ve been using it with a small FM transmitter, to listen to CDs in my car. There was always a bit of static, the CDs sounded flat and recently, a station in my area began transmitting on multiple [...]
