I've read a lot of ways for dealing with logarithmic fading on an Arduino, but this is the first time I've seen it broken into two speeds. Nice solution.
Nice catch. According to the PAM8403 datasheet, the recommended supply voltage is 2.2v-5.5v. So when I tried it with 3.7v and it worked, I pretty much forgot about it. But boosting the voltage might help. It would be an interesting thing to try.

Here; I've labeled the Bluetooth pins in my original photo, and included ElecFreaks' diagram with pin labels. The boards are connected as follows:BT pin 3 to AMP inupt (-)BT 4 to AMP L (+)BT 5 to AMP R (+)BT 12 to battery (+)BT 13 to battery (-)Let me know if I left anything unclear.
Glad you're excited about the project! I'm working on a detailed wiring diagram for you. As for your volume question, the amp I used came with a knob on it. There are a few ways you could add volume control, and you can always adjust it from the phone.
Thanks for the support. Glad to hear that the video helped. This instructable actually won me my first contests. I wasn't sure if I was heading in the right direction when I posted to the Clinic.Love the Thermal Detonator project, btw.
That's brilliant. I may just have to try that next.

Just saw it on the homepage. Congrats!
Hi, I've had a good response to my latest Instructable, but I'm always looking for ways to improve. Suggestions for what to do next time? Any lingering improvements to this time?https://www.instructables.com/id/Robopunk-Bluetooth...Thanks.
Very nice job, it's hard to find improvements.One small thing; on my monitor, you can see the background in the first image. The video thumb looks like the same photo, but with an all-black background. This has a lot more punch - I'd try using it for the intro image too.
This one's worth it for the name alone. I can't imagine needing to worry about this lasting more than a day :)
Good question. I just added the link to the parts list.I have a collection of new and vintage safety goggles, and all of them seem to have the same size lenses. But the metal ones have thin walls, so there's less material to get in the way.Hope that answers your question!

I love this, because the fact that it exists in 2016 means that it really is the ice cream of the future.

FYI, the button I sourced has an LED with a resistor inside. So it's probably smart to open yours up and see if it's an LED or an incandescent, like Bill's.If it turns out it's an LED, swapping the resistor isn't too much trouble.
