AMP UP THE SPOOKINESS QUOTIENT AT YOUR HOUSE THIS HALLOWEEN BY DONNING A LAB COAT, COLLECTING SOME PVC TUBING, LEDS, DIODES, AND RESISTORS, AND BUILDING THE GADGETS BELOW! EACH PROJECT INCLUDES A PARTS LIST (RUBBER SPIDERS, FAKE BLOOD AND VAMPIRE TEETH NOT INCLUDED), SCHEMATIC AND COMPLETE BUILD INSTRUCTIONS. HAPPY HAUNTING!
Dick Worked the Graveyard Shift
When the local church needed storm effects for a skit, sound man Dick Neubert found the thunder on the Internet and added “lightning” with a photoflash strobe. In all, this common strobe design will deliver some very uncommon effects for your next Halloween spookfest.
Cutting Pumpkins the Tesla Way
Rick Crammond created a gadget for cutting Halloween pumpkins that is powered by the faucet in a kitchen sink. The water pressure drives a stack of CDs that has been converted into a turbine.
Bill Had That Weird Sensation He Was Being Watched
Partial to things that go bump in the night, Bill built a circuit that slowly illuminates and fades a pair of red LEDs. Install it in a skull as a Halloween prop or if spooky things aren’t your thing, use it as a fancy power indicator for a home appliance.
Good stuff.
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 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
