The ‘contrast‘ between these two images couldn’t be greater:
In this simple upgrade project by Kerry D. Wong he opens up a HP 5350B microwave counter and quite easily replaces the included dim, yellow LEDs with some white ones which make the LCD text much, much easier to read. If you wanted to do something similar with one of your workbench appliances the solution may not be identical, but it shows that you never know what’s inside until you open it up and explore! The solution could be easier than you imagine.

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.
