From the Forums: Homemade Remote Control Combines XBee, Qi, #Arduino, and More!
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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
