From the Forums: an improved Bluetooth sleeping mask #Adafruit #Bluetooth

From the Forums Bluetooth Sleep Mask

From the Adafruit Forums, user DJDevon3 writes:

I bought a ProCIV bluetooth sleeping mask on Amazon (2019 updated version) but it’s barely audible at full volume. In the past, I used 3.5mm corded sleeping masks which are plenty loud but the cord breaks eventually.

So begins a quest to rebuild the mask. With some helpful advice from forum staff, the headphones were fixed and received some upgrades, including a larger LiPo rechargeable battery from Adafruit.

One of the things I love about Adafruit, if you guys say something will do X then it does X. Your electrical engineering skills are inspiring and advertising integrity matters. That’s why whenever I have a small electronics project I usually look to see if Adafruit has it first. You guys are awesome.

And the result:

I feel completely justified with how much I spent on components to create what I have now. It’s wireless, loud, 30+ hour battery life, can sleep with it on. Done with commercial headphones and sleeping masks. This is good enough to serve both roles for my needs. Well except music production I do have another pair of headphones for that. I want to make it smaller but I don’t want to give up the 30+ hours of battery life lol. A good problem to have. 🙂

See some build pictures below and the full project runthrough on the Adafruit Support Forums thread here.

Well done!

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways.
