Tell us about yourself!
Hi, I'm planning to re-create this project, though I'm planning to use the NodeMCU dev-board which is based on the esp8266. Does this schematic look correct to you?Thanks in advance!
Just decided to go with a lead to acid battery and a pre-made protection circuit, way easier to handle and twice the capacity for the same price
What would be the required steps to using a Lithium ion/polymer battery? Any tips? Your timing is excellent I was planning to build a boombox right at this point in time. I was looking at http://amzn.to/24eScbO as an amplifier/bluetooth receiver. What would you suggest as power source for something like this? Thanks!
