Forums user linuxworks sent this in a while back – it’s a great combination of multiple technologies including Arduino (you can see the IC underneath the OLED display), XBee, Qi wireless charging a LiPo battery, and some really slick components and layout. That dot PCB background is also a really great ‘feature’ of this image:
this will be my first time using both li-poly and Qi. I have a POC thrown together that uses the adafruit lipo, charger board and qi charging coil. I wired it up and I’m giving it its first test-run
And linuxworks then went on to design a case for the whole thing to fit in; kudos on the semi-transparent look that probably gives some operators double-takes:

Universal Qi Wireless Receiver Module: If you have a modern smart phone you may have noticed that it comes with built in wireless charging capability called ‘Qi charging.’ Qi is a trademark name for a thin and smart inductive charging system. Many large gadget companies have standardized on Qi, which means it’s easy to find a charging dish and we thought it might be cool if your Arduino project can recharge itself wirelessly. Thus, we now have a Qi charging receiver module as seen here here. Read more.
Lithium Ion Battery – 3.7v 2000mAh: Lithium ion polymer (also known as ‘lipo’ or ‘lipoly’) batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 2000mAh. Read more.
