(The next contest will have nearly a month) It was extremely
difficult to decide. I had to consult with Matthew {my son} to see if he agree'd
All the entries were awesome!
The Winner is: Chuck Rice with Skelly

Oldbit's Unofficial Propeller Halloween Contest
==============================
Rules are simple.. Using a Propeller (and other Parallax stuff)

gobblers on the 31st.
I will also participate (but since I'm the judge) mine will
just be for fun.
Winner will be picked (by me) on All Saints Day and
two USB Protoboards will be mailed to you.
Added: $250.00 cash prize from Parallax

Projects must be DONE and submitted to this thread

a scarecrow body below it. If I can get a servo to pull a little weight I want to make an arm that swings
on command. Just haven't decided if I want this to be joystick or ping sensor controlled.
Some scary wav's are definitely in order for sound. [noparse]:)[/noparse]
Started pulling this pieces together for next weekends' build.
Anyone else willing to share their build secrets?

My idea for OBCs contest was to have a human controlled spider thread with a spider hanging on the end. I live in a dormatory, and we have a central area four stories tall (~40 feet) with stairs on either side and a central light shaft in the middle. The project design was to have a person wave their hands in front of some IR devices, and that would control the vertical movement of the spider, and how much it swings. This way, the spider has a full 2d plane of movement. Also, a special scenaro (when a hand got really close to the vertical sensor) would drop the spider suddenly.
You can see the center cross here, where the swing servo is mounted. This is just before I took it down.
I'd just like to take a moment to say that my code works perfectly. Rather, the problem that I ran into was my mechanical. The servos that I used (Parallax standard and continuous) don't have enough torque (47 oz in), and so it created problems. My swing servo controlled the swing by running the thread that the spider hangs from through a tube, which was then attached to the servo. This servo was out in the middle of the space, and mounted on some 1/2" angle iron for stability. Anyway, too short of a tube, and I don't get swing, too long and it can't handle it. Problem 1.
The second problem was the vertical movement servo. It's quite slow under load, and it was a dull experience to raise the spider. To suddenly drop the spider, I mounted the vertical servo on another standard servo, which turned to drop so that the string would come off the side of the drum. Imagine a roll of string. Stand it up, and it all falls down. Anyway, apparently the friction is just a little bit too much, and it didn't go out like I wanted. I could have filed it down, I guess, but there were enough other problems that I didn't feel the need to.
The electronics consisted of a PPDB in side an old shoe box, with two IR LEDs and two IR recievers. Also, I put in two 2.1mm Barrel jacks so that I could provide seperate power for my swing servo and my vertical servo. I had tested earlier, and found the regulator on the PPDB getting hot.
As for safety, I took several precautions. Truth be told, I didn't really get any sort of approval for this project, and it looked a bit dubious with the liberal use of zipties. So, I took safety serious. All components out in the air are very light, with gently rounded corners so that they are fairly safe if it should fall. Next, I put lots of sting out to the center. There are seven completely independent sets of tie downs: two along the x axis, two along the z axis, one tied to the cross point, one tied to the servo counter balance, and the spider thread. Each of this were securely tied with a half hitch and a square knot to various railings.
My control box with the three power supplies and the vertical servo and drop servo mounted on a BOE-BOT Chassis.
So, that was to be my submission. Next time (Christmas?) I'll try it with stepper motors or maybe DC motors. Best of luck to everyone else!

Strangely I'm having some similar issues with servo power here too..
Might have to scale my scarecrow back just a bit.. [noparse]:)[/noparse]

Actually I'm already pondering a Christmas contest..
Something along the lines of a Propeller Christmas card contest. (Video, Mechanical, {or both}, musical)
Perhaps I will ask Baggers to be the judge as he is the obvious expert and ringer {videowise}. [noparse]:)[/noparse] <SMIRK>

Let me clarify for everyone.
Any Halloween display is acceptable to this contest if it includes a Parallax Propeller somewhere in the design.
Use of any other parts are perfectly acceptable.
Time to see if I can get mine wrapped up and working tonight.
Remember: all posts must be made by MIDNIGHT EST TONIGHT.

Here is my halloween project. I took a leather box from Michaels and made it talk! It has one servo that lifts the lid up and down. Another servo, moves the eyes left and right. Both eyes light up using LED's. The eyes were built using wire and 2 tops of roll-on deodorant from the dollar store. The audio comes from an SD card and is output through a stereo the unit sits on top off. We set it in a window and let it run all night. It plays music for a few seconds and then activates the speech routine..."Welcome to Hell" and then goes back to its idle state. I also made it so it can be triggered via IR. You can find the video at www.audiotrip.net/talkingbox.html
