When I have friends over for a BBQ or go camping, I like to have some music playing. In the past, I've used a Small Portable Speaker that I attached to a cooler. These small transducers work by transferring the sound waves into whatever surface they are connected to, essentially turning them into a speaker. Although it sounded decent, the battery life and volume was lacking....
Read MoreWhen my WLToys V939 quadcopter stopped performing well, I didn't want to just scrap it. I wanted to salvage the flight controller and try my hand at building a custom frame. The pager motors used on most mini/micro quadcopters are only rated for a certain amount of hours before they lose their strength and functionality. The batteries also wear out with moderate use. I put in an order for some replacement motors and batteries and got to work building a mini quadcopter from the ground up.

After a few years of use, the battery life started to fade and it never really put out enough volume. This year I decided to build a new speaker cooler with a bit more power and better battery life. My main goals were to keep it relatively cheap and non-invasive. I didn't want to modify the cooler in any way and wanted the components to be completely removable. This configuration is extremely easy to build and can be done in minutes...

These headphones have a good battery life of about 5-6 hours and a decent range so I figured they would work great with an upcoming project I have in mind. I decided to strip them apart and see if I could make a small adapter instead of buying a new one...

I did some searching and stumbled upon a few homemade sous vide machines using the STC-1000 temperature controller. It's cheap, available on Amazon, and came with just about everything you need for a primitive sous vide setup...
