After the success and popularity of my original QR Clock, I decided it might be a fun challenge to redesign the clock into a more attractive and lower-cost form factor. The end goal is to make this the flagship product that gets my Ch00ftech Store on its feet. Before I could start worrying about manufacturing and shipping, I needed a new prototype, so this post is to tell you about what I’ve changed.
I addressed a number of mechanical and electrical problems that I had with the original design, but this time around, I’ve also addressed some of the pricing and supply chain issues I had before. This clock is actually much cheaper to make than the original, and getting it that way involved some new experiences for me.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
