My phone cassette adapter
September 16, 2007
It’s always annoyed me that there isn’t a SIMPLE way to connect audio devices (iPods, CD players, phones, etc.) to cars. It’s fairly common place now in new cars, but not in 1997 when they build my BMW. …So I had to hack a solution.
I sync my favorite playlist to my phone and I wanted to connect that to my car. This is my end result. It cost about $20 to build and it sounds MUCH cleaner than the Bluetooth and FM adapters I’d tried in the past. It also doesn’t skip or pause randomly like Bluetooth, and you don’t have to adjust it all the time like FM adapters.
This is what my cassette adapter looks like…
Below is an up-close shot of the adapter without the phone connected. The Velcro and old Xbox jack hang off a regular cassette adapter I modified to work with my phone. I couldn’t find a cassette adapter that had a 2.5mm jack, CDs, iPods, etc. all use 3.5mm. Cell phone companies use 2.5 (because they’re evil).
Below is the adapter outside of the cassette slot. I realize it’s not that pretty, but it’s always hidden so who cares.
And here’s a video of me explaining what I did and how you can build one. Just post a comment if you have any questions, anybody should be able to do this. Even if they have almost no experience with electronics. The real trick is to go to WalMart and buy a cassette adapter that can be easily taken apart like mine.
