Whose Teensy code are you using? Make sure it's being saved and uploaded correctly, I had problems with stuff until I made sure these steps were happening. New to arduino stuff, so took me a bit :). Here's a post that might help you: https://www.pjrc.com/teensy/td_usage.html If you're still having i...

I know a lot of you have already started using AIO boards, but for those who aren't, or who may want to use the Pi Zero on another project, check out this board I stumbled upon today: http://www.ebay.com/itm/192078615448 Haven't seen anything like this, it looks pretty sweet. Looks like they had a k...

Yeah, I was just saying 7.4v to simplify the normal output of two 18650's in series, since they're considering "3.7v" by most descriptions/standards. My project is fine with the 6.6v-8.4v range. Okay, so let's say I went with the boosting the 5v from the usb to 8.4v for charging, how would I go abou...

That board you have linked from banggood is designed as a charge/project board. It will allow you to throw 8.4v at the battery, and it will (allegedly) ensure that the batteries share that voltage correctly to charge. In my experience, they will even disconnect the battery from the input/output whe...

Hey guys! I'm working on a project that I need a 7.4v-8.4v output(essentially two 3.7v LIPOs in series). I'm looking to power the project with 2 18650 batteries, but I am curious on how I should handle them, and handle the charging. Note: I'm looking to charge with a 5v, 2a USB charger. I'm thinking...

Fantastic news, guys! After having so many issues with this, I finally, FINALLY, have got everything working as intended! Thank you guys so much for the help and encouragement! @FreddyMro I didn't end up using your solution, but you got me really thinking that I had the pinout for my pot wrong...tur...

Thanks!

How much modding do you think it would take to fit this screen in with a pi zero and an adapter like this http://www.ebay.com/itm/381827326709

and a cable like this:

I'm in the same boat as you.
Are you using a USB DAC, or just a low-pass filter?
And, what amp are you using?

Wonder if we could narrow down the issue to it being the potentiometer!
