Re: Software Defined Radio

<t>I'm in the same boat as you, hurry up and wait. and I ordered mine about 8 hours after it went on sale. I would like to get familiar with the Arduino also, just not sure which one to buy. Thanks for the soft66lite info, I didn't know about that one. There are a lot of SDR radios out there and I w...

Re: Software Defined Radio

I also am very interested in using the Pi for SDR, in fact I have almost finished my SoftRock lite II kit. Can't wait to get it cranked up and start listening.

Re: Audio & PWM

<t>Thanks for all the good info, I believe at least for the time being I will go the USB route. I just bought a adapter from China for $1.50 with free shipping, it got here yesterday and I plugged into my old PPC Mac Mini and it worked great for Skype. It says that it works with Linux also, so I wil...

Re: Audio & PWM

So, I'll ask again, does anybody know what the sample rate of the sound chip on the raspberry Pi?

Re: Audio & PWM

What is the sample rate of the RPI? 96Khz would be great but I could settle for 48Khz on my SDR radio project.

Re: Short video of Raspberry Pi booting on 4 AAA batteries

Why don't you just put a silicone diode in series with the positive side of your battery cable which would drop the voltage by .7 volts then would only be 5.3 volts.

Re: Cases for the Raspberry Pi

What about using this case? It is slightly larger than an Altoids tin so might work.

Re: Smallest USB WIFI + BT adaptor

The one n3tw0rk5 found already has Linux support, but probably not arm support.

Re: A program to type in, like you used to

<t>I spent a weekend inputting a vignere,(spelling may be wrong) cypher program into my ZX81. It worked real well, you could choose a seed of 4 digits I believe, then type a text document as long as you wanted. When you got finished you told it to scramble it. It was totally unreadable afterword unl...

Re: Creating SD Image on Mac OSX using dd

<t>I copied my 4GB sd card on my Mac Book Pro using the SD slot and everything works fine except that the instructions I used were wrong and had a extra set of DD's in the middle of the command. I have done this before and realized that it wasn't supposed to be in there so left them out and it copie...

Re: industrial case

<t>Back in my Ham radio building days we used to use thin nylon channel and attach it to the sides of the enclosure then slide the circuit board in to the channels thus not needing any mounting holes. The only problem is, the enclosure needs to be the exact width. We used to make our own boxes too s...

Re: Deploying Images to SD Card

This might be a stupid question but, what happens if you "DD" the 2gig image to a 4 gig card? Should you partition the card to have a 2 gig partition or will the DD process do that for you. Frankly, I could not find any 2 gig sd cards at my local Wal-Mart.
