Smartphones, tablets and other portable devices that need electricity rely on batteries that use a chemical reaction. But Maxwell Technologies, a company in San Diego, announced Tuesday that it was providing devices for television remote controls that store electricity without chemicals.
The devices, called ultracapacitors, are a little smaller than the two AAA batteries they will replace. They can recharge within minutes and have a life span that will probably outlast the remote control, said Michael W. Sund, a spokesman for the company.
Maxwell said it was approached by Celadon, a company that makes remote controls for set-top boxes, with a request for a power system that could work with a remote control.
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.
