Hi Everyone, I've been lurking on this forum for a while without making a post. I'm a standup comedian based in London and I'm trying to hack a teddy ruxpin much like a few other posters have done here.

I've been doing research but I'm still fairly confused.

A wee bit about me I'm used to working with software but software with a GUI. I can write CSS & HTML but that's about as far as I am with code thus far. That's not to say I couldn't learn; and I was rather looking forward to learning some code in this project but the question is which code!

I'm not amazing with my hands but I'm not averse to soldering, cutting and glueing.

I'm quite good at working through problems.

About the Project.

What I want to achieve is the following:

1. Teddy Ruxpin needs to be able to:

  1. Move mouth
  2. Blink
  3. Move head side to side; ideally, 360.
  4. Move arms up and down
  5. Flap arms.
  6. Move head up and down

Essentially everything that Waldes on this forum managed to do:

2. I need to be able to have a 'script' for Teddy Ruxpin to say and do. I will be able to talk to Teddy Ruxpin and then trigger the sentences with my iPhone or a bluetooth clicker hooked up to my Mac.

3. Teddy Ruxpin needs to blink in every 20 words or 20 seconds (however often the human blinks).

4. I need to be able to program specific blinks and mouth openings too. For instance

i)I click the bluetooth remote Teddy says hello there

  1. I click the bluetooth remote Teddy blinks twice.
  2. I wait 20 seconds without doing anything, Teddy blinks twice anyway.

5. Ideally, it would also be great to be able to talk into a microphone and have Teddy Ruxpin speak it, together with some automated movements.

The Current Situation

I bought a Teddy Ruxpin that a guy had already pre-hacked for an art project. www.afrugallery.com/sean/ I hooked it up to an Arduino Uno and some software he provided and have been successful in getting the mouth to move, eyes to blink. That's as far as I got. I bought another Teddy Ruxpin knowing that i was going to have to take on the whole thing myself if I was going to be able to customise it to my liking.

Equipment I have as of December 2014

1 x Bearduino arstechnica.com/information-technology/2013/07/bearduino-hacking-teddy-ruxpin-with-arduino/ 1 x Arduino Uno 1 x Regular Teddy Ruxpin (unhacked) A lot of enthusiasm.

So, where do I start guys?

I have a mac but I can run Windows in a virtual environment. I make presentations during my comedy and use keynote for that. It might well be that I would need to run the Teddy Ruxpin separately from a different computer anyway; ideally my iPad I think to be honest.

I know this is a LOT to take in but I would LOVE to get any advice from you guys about where to start. I mean I literally don't know where to begin. The main thing i"m worried about is the software; I mean I know nothing about programming an Arduino. But I'm a fast learner and raring to go.

All best wishes, James

Thanks so much. I'll order it tomorrow.

The Dev kit arrived as well has a ton of other stuff. Expect many many many (dumb) questions to follow.

First one; The lynx-motion pan and tilt says that its operating speed is

0.16sec/60 degrees at 4.8V 0.14sec/60 degrees at 6.0V

But the EZB outputs 7 volts, right? Am I going to fry it if i plug it in? I only ask because I may have just plugged it in and it may have started to make a noise.

#46  

You're ok... all servos make a buzzing noise... excessive noise and smoke are bad however..., That will happen if they are locked (trying to move but are binding or something is preventing them from moving) or trying to move a load that is to heavy for the servo... Are your servos ez robot or Hitec servos? The ezb outputs whatever battery you have it attached to... If your using a 7.4v battery then your servos are getting 7.4V... If you are using the ez robot servos from the kit then you're fine with 7.4v batteries

I'm using the EX robot human body which has a battery inside of it. And, though I also have ez-robot servos, I'm currently trying to get the hitec pan and tilt one to work

The battery the body comes with is apparently a 1 x LiPo Battery 7.4VDC 1300mAh
