  1. Speaker/Soundboard/Tablet Help

    Halloween Props
    I think you're running into a limitation of Bluetooth. Each Bluetooth device, like a speaker, links to one other device, like a smartphone or tablet. I don't think Bluetooth has any concept of channels. The only way to make this work is to have one tablet or Smartphone linked to each speaker in...
  2. It's Your Funeral

    Party Ideas. Experiences and Recipes
    Someone I know made a "Wheel of Misfortune" - imagine one of those big prize wheels you can spin. They told people, "Imagine you're in a scary movie! How will you die? Spin the wheel and find out!" When it stopped spinning it pointed to an icon. A chart listed the meanings of all the icons...
  3. Electronic/Software: Anyone using the Parallax 5-position switch?

    Halloween Props
    If you check out the blog post I linked to, there is a wiring diagram and a link to sample Arduino code.
  4. Electronic/Software: Anyone using the Parallax 5-position switch?

    Halloween Props
    That's a small joystick-type switch, so you can use it to control several outputs live. I did a quick search and someone did a blog post on using it: http://blog.smilingdogsystems.com/2014/11/lighting-leds-with-a-parallax-5-position-switch/ You could substitute relays for the LEDs and turn on...
  5. LED flame lamps?

    Halloween Props
    A friend put some of these in Tiki torches...they looked terrific! Of course, they were next to skeleton Pigmies roasting a captured pirate...
  6. Electronic/Software: Need help to get started in Arduino

    Halloween Props
    There are plenty of tutorials on Sparkfun.com and Adafruit.com to get you started. Haunters usually start with an Arduino and a few relays. Then you can control two or three props, lights, etc. Trigger them with a button or a PIR motion sensor. If you have a few props that run with “Try Me”...
  7. Mechanical: Spirit Halloween - Cryo Chamber Corpse - AVOID!!

    Halloween Props
    It pops up fast, just like in the video.
  8. Mechanical: Spirit Halloween - Cryo Chamber Corpse - AVOID!!

    That's with the usual 20% coupon applied.
  9. Mechanical: Spirit Halloween - Cryo Chamber Corpse - AVOID!!

    Halloween Props
    It just occurred to me that a way to fix this might be...zip ties. More later, I have to get back to work.
  10. Mechanical: Spirit Halloween - Cryo Chamber Corpse - AVOID!!

    Halloween Props
    Here's the hinge. It clips to a metal rail so the top can pivot. The finger on the lower right snapped, and it also provides support where it is screwed to the lid. Note that one of the two screws, and probably a few more bits of plastic, are still lost on my floor somewhere. This is cheap -...
  11. Mechanical: Spirit Halloween - Cryo Chamber Corpse - AVOID!!

    Halloween Props
    My wife saw this new prop on Spirit's website: http://www.spirithalloween.com/product/2-5-ft-cryo-chamber-corpse-animatronics-decorations/145170.uts?relationType=recentlyViewed&thumbnailIndex=0 It looks great, when it works, but it is way too fragile, so I can't recommend it. Here's my story...
  12. Electronic/Software: Use for old Computers?!

    Halloween Props
    They can play back videos or music. Or if you're ambitious, control animatronics. If you have a mad scientist lab, put a fancy techno screensaver on them.
  13. Electronic/Software: Cheap Controllers for Props

    Halloween Props
    Hey Wbn, did you get that Monster Moto board in yet? Let us know how it works out.
  14. Electronic/Software: How do I trigger a blender with a motion sensor?

    Halloween Props
    That's a great gadget. The only limitation I see is that the minimum amount of time it's on is 1 minute, which could be way too long.
  15. Electronic/Software: How do I trigger a blender with a motion sensor?

    Halloween Props
    One solution is a simple prop controller which has a PIR and a relay attached to it. The controller is set up to watch the PIR motion sensor, and then trigger the relay. The blender should be an older one which can be left on with a mechanical switch, so the relay would switch the power to the...
  16. Electronic/Software: DIY Wifi Controlled Props

    Halloween Props
    Look for the ESP8266 modules. You can use them either as a wifi connector for an Arduino, or you can configure them to run like a small Arduino with built-in wifi. Tip: Avoid the really small cheap ones with only six connections, they're called the ESP-01. Get one of the ones with all the...
  17. Lighting: My Stranger Things Alphabet Wall

    Halloween Props
    The California Academy of Sciences in Golden Gate park asked me to bring my Stranger Things wall to their "Weird Science" event last night (11/3/16). Here's a photo of it set up before the people came in.

  19. Lighting: My Stranger Things Alphabet Wall

    Halloween Props
    Look at this section of the code: // For 50-pixel strand case 'A'...'H': return 50 - (c - 'A'); case 'I'...'P': return 30 + (c - 'I'); case 'Q': return 39; case 'R'...'Y': return 26 - (c - 'R'); case 'Z': return 17; Look at...
