Solar System Orrery (3D Printed)
8 Planet Motorized Orrery - 3D Printed
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.
How to Hide a Screw
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.
That's brilliant. I may just have to try that next.
Simple Tea Bag Extractor
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!

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.
