Yep, that's completely different. I did some digging, that skull is by Seasonal Visions International, so it's a totally new design. I'm always impressed by the effort that goes into this kind of product. For something that's designed to be an inexpensive gadget, that's a lot of work.
FYI, when I opened up the skull I purchased at Target, it seems that it's not a Gemmy after all. Or at least it's very different than the talking skull in this project. It uses a Piezo element to trigger the skull and all the components are in different places as well. Quite an elaborate work of engineering. I'm attaching photos in case you're interested/
Oh, in that case, any mp3 board that an Arduino can control is fine. I mentioned the Catalex board because it's cheap and there are currently a lot of ebay sellers. The challenge would be getting it in time for Halloween, since most sellers are overseas. Here's a link to it on dx.com, this should stay the same, the ebay links come and go: http://www.dx.com/p/uart-control-serial-mp3-music-...Also look at Sparkfun or Adafruit for US-made mp3 boards, and they both have tutorials on using them.Whatever you get, you'll take the audio out of the mp3 board and run that into the DC motor driver board, which will control the motion of the skull's jaw.Blue Point tends to sell just what you need to assemble the kit. But Adafruit and Sparkfun will have all the other parts you need. You can also look at Jameco, they are one of the established Silicon Valley electronics part suppliers and have a big inventory. Finally, Radio Shack may have the other parts if there's still one open near you.
Actually, I'm not that new at this. I have a couple of Halloween props that are pretty advanced, including an (Arduino-controlled) owl whose head moves randomly and eyes light up when triggered by a motion sensor. I guess what I'd really like to do with this talking skull is be able to change what it says and have it all triggered by a motion sensor. For that I’ll need an Mp3 board paired with an Arduino? You mention the Catalex MP3 board in one of your comments. Does Blue Point sell the phone jack and plug and 3.5mm stereo jack, PCB mount, etc.?

Has anyone done that?
Blue Point sells the board alone, or with all the parts you need. However, if you've never done any hobby electronics, this project might be a bit too advanced for you. The skulls change a bit every year and you'll have to figure out how what you got works compared to the one I have. Also, this only explains how to animate the skull - you probably still need an Arduino or similar microcontroller to play back sounds automatically.
Gosh, this is amazing. I happened to pick up one of those Gemmy skulls from Target yesterday and I was looking for ways to modify it. At least I think it's a Gemmy skull. Except mine is sound activated, not motion activated. Quick question: If you buy the ready-made circuit board from Blue Point, what other parts from the list do you need? Do you still need the diodes and resistors? I'm obviously new at this.

Control A Fog Machine With Your Microcontroller
Hi, the new company, Blue Point Engineering, now has the boards in stock and has put up a web page where they can be ordered. The info is in Step 2.
figured out how to get the program onto the board, now have suggested amp board attached. will ramp up randomly without momentary switch input. troubleshooting now. help would be appreciated
How To Make A Fake Geiger Counter
If you're not familiar with any Arduino concepts, go to the tutorials at one of these websites and work through hooking it up, loading a simple blinking LED program onto it, etc.Adafruit:https://learn.adafruit.com/ladyadas-learn-arduino-lesson-number-0Arduino:https://www.arduino.cc/en/Guide/HomePage
Maybe we chose this as a bar too high for our first arduino project. step two you gloss over just how to get the program onto the board. saying you can put it directly onto the chip. so how...
sorry, i was referring to the talking jemmy board.
Cool, I was considering the manufactured Jem board on the other forum (as you are aware). However, it could potentially be more advantageous to use a board like this that responds to tones more predictively (especially if I can adjust it to respond to low tones on my keys). I already have a talking skull I built that moves to the audio but it can be a little touchy to adjust. I do a lot of latex work to these props and since I enjoy it I'll be pumping out a lot. Too many to buy a lot of Jem boards.
Not for nothing, but I don't think the listed person at SimpleCircuits supplies this board anymore. I attempted to contact them and their email no longer works. Can you build this circuit ok using one of those simple plastic bread boards?
Modify A Talking Skull To Say Anything You Want
I ended up building mine in an old 720 civil defence meter, based on the instructions from "The Tinkerers Apprecentice" below. Used an Adafruit Mono 2.5W Class D Audio Amplifier - PAM8302 (https://www.adafruit.com/product/2130), and works perfectly ($3.95), and a barebones arduino.Has anyone ever mad any luck in getting the old Civil defence round meter to work via PWM or something else - this would be perfect. The meter is marked as 50 micro amps, but I don't know it's internal resistance
Yes, that looks like the problem Jeff - all I need to do is push a wire into the 9 pin, and it goes wild - seems extremely sensitive, and I'm not sure how to decrease the sensitivity with your style of code. I was trying to use DigitalRead, but not sure if I have the right piece of code.Thanks for replying - this is my only problem.
Hi allI've just made one of these with an Arduino UNO, and it works fine, except sometimes seems to spontaneously go into "detection" mode i.e. as if the button has been pressed, but it hasn't. I can't read this style of Arduino code - anyone have any suggestions?
Thanks for the inspiration. I 3D-printed a project enclosure that I designed to fit my parts, which cut down on the work to create standoffs and countersinking for the jack. In hindsight, I should have designed a strain-relief for the cable.I had a two-relay module sitting around, so one relay is unused. In the future, I'd probably consider using RJ-45 (network cable) jacks for the low-voltage signals. That would make it possible to carry more signals around and perhaps make use of the second relay.
