He's a big boy alright, and it is a good price indeed. As you say, perfect for an EZ hack. Shame I don't have a Walmart near me, but I've got enough going on with my Astromech build anyway. I'm sure someone here will grab one and have a play.

It's already been done a few times... I hacked the Interactive astromech R2-D2 two years ago with an ezb3... The Interactive is 18 inches tall.... Is the one you posted different somehow?

@richardr yea this one is like 50 bucks, and easy to get. The old Hasbro one, which i have as well is a pain to find now and pricey. Also the interactive one is not as big as this guy

Ah, gotcha.... Thanks

Good find @Jayutmb, does it come with motors and sensors?

Ironically enough I am hacking an interactive R2D2 at the moment, I bought mine second hand for $50

@Richard R did you end up re-using the sensors in R2's head when you did your build?

Hey @Jeremie I Just kept the speaker and motors.... I gutted everything replacing them with off the shelf components like leds, pings and PIRs etc... Later I eventually took the dome rotating dc motor out (because of a lack of position control) and replaced it with a servo.... I also used a sabertooth 2x5 as the motor controller...

Yeah that dome rotating motor is super fast lol. I will likely try using the onboard encoder to get positional feedback and apply lots of PWM to slow it down.

I was thinking about reusing the onboard Ultrasonic and PIR but I'm not having much luck with the sensor board. I'll likely try a bit more and if I don't have success then I may hack in the electronics from an ezrobot Ultrasonic senor. I'm not sure what I'll do with the PIR since I've never directly interfaced to a raw PIR sensor before. I know a lot of them have voltage boost and amplification built in and I don't want to have to recreate that.

@Jeremie ... I am super jealous of you electronic skills... I keep saying I really should take some community college courses and learn more stuff like this.... I think it will be my new years resolution now... So C# and some intermediate electronics's courses are on the list....
