@Rcurl....nice idea. I saw a similar thing done recently with the good old LM3915 LED level meter chips to give 1dB increments instead of the usual 3dB. And I got some chips that generate and provide a notch filter for 2600Hz tones used in Radio keying systems, I was going to underclock them to get the notch down to 1000Hz. However in this case, according to Max's diagrams, the bands are fairly wide anyway, so I don't know if you'd really gain much here?
@David: "However that leads me to my question...with only 7 frequency bands and 2 channels will your BADASS display now only have 14 channels instead of the 16 in the diagram?"
I notice that you can set the oscillator frequency of the chip externally. I wonder if you could intentionally skew the oscillator frequency of a second chip being fed the same audio input to get some extra bands in between the intended ones?
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
