Hey anyone...Ok - here's what I've heard for project ideas (and some commentary
or questions):1) AM modulator to interface Sirius satellite radio with a
Atwater Kent console radio I get the idea that you want something like this:
(except this transmits FM instead of AM).The input is either a USB-stick or
an audio jack (from satellite radio) and the output is a transmitted radio
signal.http://www.walmart.com/catalog/product.do?product_id=4956678
Interesting project, and it probably wouldn't be too hard. Let me know if this
is what you're thinking about.2) Akustica digital microphone decoder I believe
this is a surface-mount microphone chip that outputs a PDM digital signal. Do
you simply want a board with a PDM decoder and some memory, so you can read
the audio signal into a CPU? I think this interface would probably be
included on their evaluation board... What kind of application are you
thinking of?3) Programmable ethernet clock radio Interesting... Sounds like
everybody's got an idea for this one. This really sounds like a simplified
linux box with TinyOS. Sounds like Gumstix Linux, or a simplified and cheaper
version of it... This could turn into a really cool project if the goal is
to see how cheap a linux-alarm clock could be designed... I'd need LOTS of
help putting the OS into the hardware.4) Software radio receiver Very
interesting. I also used to follow the gnuradio lists and started looking at
their software, but fell by the wayside when they were asking for mucho-$$$
for hardware... What kind of application would you want this for? That would
determine frequencies, modulation, and sensitivity/linearity
specifications...5) Cheap lab test equipment... I'm very interested in this.
Actually my last project was to replicate the Wispy ISM-band spectrum analyzer
made by Metageek and now selling for $200. I estimate the hardware should
cost around $20 and the software is free. I was hoping to eventually build on
this design and expand the frequency range and performance - but I haven't
gotten there yet and I don't really know if anyone would be interested in it.
A question I have for you is... Who wants this stuff and what would you use it
for... There is already audio-frequency digitizers/samplers from various
software radio projects. I think there are also cheap multimeters for HAM
radio hobbyists. Are you looking for something like this, with a USB-port
interface? Or something different?A USB-oscilliscope would be very
interesting, but it would take some serious software support that I couldn't
provide.Good ideas so far!Jason
