The Great Search: Replacement capacitors for old boards #TheGreatSearch #digikey #adafruit @DigiKey @adafruit
This week on the Great Search (video) we’re going hunting for caps! When resuscitating an old ‘retro’ board, it’s pretty common to need some ‘recapping‘ done – particularly with tantalum, polymer or electrolytic capacitors.
Figuring out the capacitance and voltage rating is not always easy. there’s a great thread over on the DigiKey Tech Forum which has lots of photos of a wide range of capacitors. Looking it over, we learned new things, like that that SMT voltages are encoded with a standard letter!
Let’s go through some of these examples to learn how to identify replacement capacitors from the top marks alone.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat and our Discord!
