OK.. This is a cool product, but in the demo video, he talks about effects pedals like the one that made Frampton’s “talk box” sound.. If I’m not mistaken, I believe there was no box for that.. He connected a tube from a funnel by the speaker to pick up the guitar sound, and then put that tube in his mouth by the mic, and used the shape of his mouth to make the guitar sound like it was talking… No box needed!

SIGN ME UP.. If I could get an Arduino to talk straight z-wave to my Vera, I’d be all over that!!
Oh wait.. there’s that sparkfun bilge pump I bought… Why did I buy a bilge pump? I dont know.. I have a pool and a hot tub.. somewhere in my brain there’s an arduino controlled pool water level controller project, or some way to pump hot tub water into the pool to heat it, but for now, it sits in the box.. :-)
Wow.. it’s as if you ONLY read my response.. Those were all my answers! :-) And yes.. the number of STARTED projects FAR exceeds the finished project, as I sit at this keyboard looking at an 8266 Thing Dev board plugged in and running but not doing anything, and Arduino UNO with Ethernet shield, plugged in and running nothing, a Pro Mini plugged into my computer running nothing, an Arduino mega sitting sadly unplugged, 2 RPis in boxes still, and a sparkfun robot chassis half built with a motor controller hanging off the side…. oh wait.. there’s another UNO.. And, that’s just the tech visible on the SURFACE of my messy desk, each related to separate projects that bumped another off of the front burner.. :-)

So.. that’s interesting, because I was actually coming here to post a question about it’s ability to DETECT a cat.. The video says it works best with a flat surface (of course) but if I just need to detect the existance of a fluffy cat getting ready to jump up on a birdcage, would it work… OR, would the 40khz be annoying enough to keep the cat away, and/or should I NOT do it because it will annoy/hurt the canary?!
For me, it’s the reliability and consistent quality, the support site, and often times the speed to get it to me.. I buy my fair share of “cheap stuff” off of the internet when I see something interesting, but dont have a particlar project in mind, but if I know I need something specific, I try to go to sparkfun.

But what does the WHITE button do?!

It looks like the output is open collector.. Does that mean I would be able to power it with 5v for the longer range, and have the output pulled up on a 3.3v GPIO pin on a RPi? I figure if the reader is going to either be open or grounded, then the “high” voltage could depend on the pin it’s connected to? Or.. am I missing something?
Tutorial - ESP8266 Thing Development Board Hookup Guide

Thanks for this great tutorial.. I’m having a strange problem though.. I was able to get the PHANT demo working, and then I went to solder headers on the dev board, and I came back, and it would no longer connect to my WiFi. I thought for sure I had destroyed the THING board with excessive heat during soldering, but I uploaded a standard ESP8266 “AT” command set firmware onto it, and using that firmware, I was able to connect to my wifi with no problem.. Loading the “Scan wifi” demo under Arduino works fine too, but for some reason, the PHANT demo never connects.. I keep getting a fast flashing blue light, and the wifi connect keeps returning status code 6 (not connected or connecting, I can’t remember which).. All my other WiFi devices are fine, and I have been fighting this for days now.. Is there anything strange that could explain this?! Thanks!

Since this is “unregulated”, is it not appropriate to use these to power the pi through the GPIO pins? I know it sounds stupid to cut off the connector and connect to the pins, when there’s a perfectly good micro USB on here, but in my application, the physical box is just wide enough for the pi, so I can’t have anything sticking out the side, so I’ve used the 2A regulated wall wart and powered through GPIO in the past, but I’ve read that it’s not a good idea with unregulated power… I guess it’s time to build a small regulator/fuse board that I can put on top of the pi for this..
