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.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
