From the Desk of Ladyada – The Great Search at Digi-Key: Inductors! @digikey
From the Desk of Ladyada – The Great Search at Digi-Key. A new feature on Desk of Ladyada, we’re still searching for the best name 🙂
On our first episode of The Great Search with Digi-Key we go hunting for an inductor! Boost converters are ultra-integrated these days, so other than a few resistors and capacitors, we only need to spec out the power inductor. It’s important to pick the right one – small enough to fit on the PCB, with enough current carrying capacity for our boosting, and low DC resistance for high efficiency! Join us as we show how to whittle down the thousands of available inductors to a few choice options.

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.
