Very cool, if not a tad cumbersome. ^_^

Nice, have you taken it out in public yet? If you do I bet you will get some curious reactions from people.

Not yet; I just finished it this afternoon. It'll be fun to use this on the freeway and see what people do. In fact, I'd---

Oh YEAH?! Well I have something older than a WECO desk handset AND a candlestick phone! Behold, magneto-cell! It takes some getting used to and requires new users to beef up a little, but the end result is definitely worth it.

Hehe, just kidding. It looks like it came out pretty well. It reminds me of a "Pokia" handset. See http://search.ebay.com/pokia

nice, i built something similar, for the nokia, i just took a handsfree set and put it inside the shell, and replaced the earphone, not as sexy since it had plain thin handsfree cord coming out the bottom, worked pretty good for scanning, tried it on my accoutic-cup adapter but modern digital service would not pass enough sound-range to let it work for modeming..

actually, the problem is that mobile phones only give you about 1/10 to 1/5 of the bandwidth a standard ulaw pcm call over t-carrier does; the audio is compressed to hell before being transmitted. A standard DS0 gives you 64 kilobits of bandwidth per second; a mobile phone gives you somewhere between six and nine kilobits per seond depending on the codec in use.

Most people don't pay enough attention to the audio and don't realize that there's a difference, although personally I can barely tolerate it (this is why I used maybe 75 minutes of airtime last month). The codecs are designed around the effective transmission and reproduction of speech, but music doesn't do too well with them, and since modems require precise tonal reproduction, they really don't do well at all with the artifacting introduced by most if not all compression schemes.

Now, if I could get a ulaw channel on my mobile phone, that would rock. :D

Yet again, Strom, I must thank you. That just made my day. Your grammar sense must have been tingling!

I've always liked that idea of a handsfree set with a retro reciever. It just reminds me of the The Pokia.

Hey Strom, will you make me one?

Wow, that made me feel warm and fuzzy inside.

How hard would that be for a novice solder-er to do?
