t’s cold outside! So grab a copy of the Hackaday Podcast, and catch up on what you missed this week.
Highlights include a dip into audio processing with sox and FFMPEG, scripting for Gmail, weaving your own carbon fiber tubes, staring into the sharpest color CRT ever, and unlocking the secrets of cheap 433 MHz devices. Plus Elliot talks about his follies in building an igloo while Mike marvels at what’s coming out of passive RFID sensor research.
And what’s that strange noise at the end of the podcast?
Take a look at the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

Ok, I’ll bite and leave a comment. I’m enjoying the HaD podcast during work. Thank you for taking the time to produce them.
Hooray! Anything else you’d like to hear? More of this, less of that?
We’re loving making them.
Thanks for the podcast. I developed (very messy code but still) software for my local perl mongers group for automatic publishing podcasts / screencast after meetings, using Sox, perl, automatic speech generation, etc. See https://github.com/japharl/DC-PM-Podcast-Software The podcast is now defunct, but still fun memories.
I am loving these podcasts. Listening to number 3 a second time.
Do you have any links for the $1 ebay rf modules, or search terms?

On ebay, I just type in “433 mhz” and get a page full of mostly the right devices. Most hits have “sender” or “receiver” in the title too, but I didn’t need it to get the right hits.
That doesn’t make sense. I post and it asks me to log in. Then posts again. Hmmm… I’ll log in first next time. :-/
