This is the part I hate when it comes to portable projects, How am I going to power them. I could have used AA battery's but I hate waste so It had to be rechargeable. I had recently torn down a pound land power bank and found a nice small lipo charging and boost board inside. I thought I could use this power my project.

The only problem was I would have to have 2 micro usb ports sticking out, One for charging and one for uploading code to the arduino but other then that it worked a treat. This also meant I could have it plugged into a power adaptor without having to worry about over charging the battery
