OLEDs (organic LEDs) have some significant advantages over traditional LEDs: They can be made on bendable substrates, are cooler to operate, and have a large light-emitting area. They’ve already gained popularity in displays. So what’s holding OLEDs back from use as a light source? Their two big drawbacks are high cost and short lifetime: Each Philips Lumiblade, the product used in the installation shown above, is about 3½ inches square, has a lifetime of 10,000 hours, and costs about $168 each in quantities of 100. So far the most impressive applications for OLEDs are in public or private venue installations, such as this one in a nightclub in Kuala Lumpur.
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.
