Default Singing Pumpkins using servos

Ok, someone gave me this idea last year and you know how ideas can sit and fester. Well after last Halloween, I decided to make some singing pumpkins to entertain the TOTs.

The parts list is so far:

-4 425BB Hitec servos
-1 Linxmotion controller
-4 single-channel LED boards (made by azdude) for the eyes
-4 Foam Pumpkins
-4 servo extensions
-4 Lucite plates (this will hold the pumpkin and the servo)
-4 servo brackets (made by 5artist5)

I've included pictures of the foam pumpkins before and after I cut out the mouth parts as well as a picture of the single-channel LED boards (I turned the boards over as the design for those belongs to azdude so if you want it you will need to contact him).

I still need to cut out the Lucite plates to hold the pumpkins and take pictures of those.

Still more to come.

Me too! It seems like I never have enough time or moola for a 3 axis, but this may be doable!

Hmmm...total the item list up. I think you'll find the cost to be more than your first impression.

DarkLore you forget the best thing of all...sales! I got the Pumpkins for 60% off after Halloween last year and I'm working on multiple servos via a certain online auction site everybody knows. I had the Lucite lying around from an earlier abandoned Xmas project from years ago (tried to make picture frames as gifts). If you buy a kit, you can make your own servo extensions (discovered that with the 3-axis skulls) cheaper than buying them.

I wasn't going to do LEDs for the eyes, but azdude mentioned it might look good so I thought I would give it a try (that and he built them to work with the controller which was very cool).

I'll try to price everything out, but this will work out to be WAY less than a 3 axis skull. The reason I know is I built 8 of the 3-axis skulls last year and that was a bit pricey (but fun).

P.S. Group Buys help too.

I love servo driven stuff. Keep going. I want to see the whole build in progress.

Hi. I was checking around and I found a place online that sells the linxmotion controllers that offers a discount on multiple quantity orders (10 for $37.95 each and 25 for $36.05) other wise each is still $39.95. The servos they sell for $14.99, but for 10 the price drops to $14.39 and for more than 25 the price drops to $13.81. http://www.robotshop.us is the website if you want to look around. If there is enough interest, I might try getting a group buy on some basic parts started.
