10257 Lego Carousel 2017 with automated sound brick

Recommended Posts

Hi there,

I have always wanted to purchase the original Grand Carousel, but missed out on it the first time and was not willing to spend thousands of dollars to got a hold of it aftermarket.  I was so happy when they announced the new 2017 Carousel.  I think it surpasses the original in almost every way.  The one thing I felt that was lacking was the sound brick.  After assembling the new 2017 Carousel and motorizing it, I went about seeing how I can add the sound brick.  Bricklink is selling this one piece for between $200 CDN and $650 CDN!  There was no way I could afford it.

Luckily I found an ebay seller from Korea selling these for $25 US plus shipping.  These look to be official Lego bricks but probably reprogrammed.  I ordered one and it arrived 3 weeks later (South Korea to Canada).  I added just 2 additional parts to automate the sound so that it would automatically turn on when the motor is activated.  The sound plays for just under 2 revolution.  After the first revolution, the trigger is hit, but the sound brick does not stop.   After the second revolution the sound bite ends and there is about a second delay before the trigger is hit again, starting the music up once more.  This results in continuous music with about a 1 sec gap every 2 revolutions as long as the motor is running.  Overall I'm very happy with this enhancement.  I thought I would share in case others are interested in doing the same. 

Here is a link to the ebay item: https://www.ebay.ca/itm/LEGO-10196-Grand-Carousel-Replacement-Custom-Same-Sound-Brick-/202109147514

Here is a video of the sound brick added to the carousel: 

Here are the additional pieces I added to automate it:

finally, here are the pieces assembled.  You can see the yellow cylindar activates the sound brick every revolution.  I chose this solution after many variations because it's a round piece hitting a round piece, which should minimize the wear.  Additionally, it's only 2 additional pieces.  If you have any suggestions on improving the activation, please leave a comment.

I hope you find this useful.

Thanks!

The 2 pieces are :

The Technic piece just slides into the activator button of the sound brick.  The Round Brick is inserted into one of the Axle (poles) of the carousel.  I found it easier to insert it from the bottom.  You need to remove one of the blue tile pieces, then disconnect the axle from the carousel from the bottom without disturbing the top too much.  Slide the connector off the axle and then slide the 2x2 round brick onto the axle.  Then reassemble.

Hi there

It was great to find your post about sound brick for carousel set. Many thanks.

I have bought 2 of these bricks, they work fine and sound great. (as stand alone)

But it doesn't work on my set. It seems that the 2x2 round brick does not push trigger pin far enough, so the music didn't start. I have switched/mounted both sound bricks, non of them were trigged. 

Has any of you experienced the same issue? Any suggestions where the problem could be for my set? 

Much appreciated for your answer. :)

Best regards

Liu

try to pull the axel pin out a bit so it's not all the way into the sound brick and see if that helps.
