I actually managed to complete a Halloween project in time
for Halloween this year. 😉
Rather than trying to find time to wire and solder a dozen LED throwies, I am using some LED strips to create the illusion of glowing creature eyes, lurking in the shadows around my house. I am currently using a Particle Core and 2 meters of WS2812B LED strips. I have another Core, a Photon, and a few more meters of LEDs, so I can probably put some in the shrubs, some under my porch, and maybe some in a tree. In a recent battery test, a “lipstick” style 2600 mAh portable USB battery powered 2 meters with 8 pairs of eyes for nearly 8 hours.
Adafruit NeoPixel Digital RGB LED Strip – White 60 LED – WHITE:
You thought it couldn’t get better than our world-famous 32-LED-per-meter Digital LED strip but we will prove you wrong! You wanted twice the LEDs? We got it (well, its 1.875 times as many but that’s within a margin of error). You wanted thinner strips? Now only 12.5 mm wide, 10 mm if you remove the strip from the casing. You wanted less noticable strip color – this strip has white-colored flex PCB, which will be less visible against white-painted walls. This is the strip with white flex PCB, its identical to the black 60 LED/meter except it has a different color mask on the flex strip. (read more)

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.
