Ben Ryves posts how to fix those pesky buttons and other plastic parts where the retaining peg has snapped off.
It’s not uncommon for parts of old electronic devices to have damaged plastic pegs, like the one in the photo above.
If you still have the snapped off plastic peg you may be able to glue it back on, but this can leave a weakened part that doesn’t hold up very well. In other cases you might have lost the part entirely. This happened to me recently with the purchase of a six-button Mega Drive control pad… Unfortunately, it arrived in a filthy condition with a d-pad that only worked if you pressed the buttons very firmly and a non-functioning Mode button.
The pressure had snapped one of the plastic pegs of the Mode button off and it was nowhere to be found, so a replacement was needed.
Fortunately, Ben had some scrap plastic parts from cutting out holes in plastic enclosures. A new peg was needed that was 1.8mm in diameter. A piece of paper clip is ingeniously used to join a new carefully machined pin to the existing button.
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.
