Hey All!
Finally got some time out in the garage. Sorry that thing called "Life" got in the way! ;-)
Some pics. (Sorry I didn't have my fancy camera with me)
Hasbro R2 in bits and pieces
A close-up of my dome posts. This is how it is on my full size R2. Simply friction fits down on the (4) screw posts.
L298 Motor Controller. Seemed like a perfect fit to mount on R2's center foot.
Another view of R2 gutted.
Back half of R2's body. I utilized the existing mounting posts and added a styrene plate for mounting stuff.
A good view of the rear half of R2. I did some extensive dremeling and removed the whole battery compartment.
Here we have everything fitted back together. EZ-B board mounted.
Gutted dome. Note the black tipped posts. Those match my screws for the friction fit.
Little buddy all back together.
Heart beat...
Another view of his almost complete internals.
12V Lipo 1500mAH battery I've been experimenting with. Fit's in R2 and Wall-E easily. Doesn't seem to run the EZ-B very hot at all.
Things left to do to R2:
- Add Scorpion Mini speed control for dome rotation
- Add serial MP3 card w/amp
- Add Camera to dome eye
- Add slip-ring to dome
- Locate and mount Sonar
Hope these pics help other builders with ideas.
Cheers!

Wow can you imagine how fast he would be at 100 percent. Nice man
MP3 board mounted and working. 3W amp is mounted behind.
Speaker in dome for now.
Tomorrow I'll try to get his sonar mounted and maybe some LED's up in the dome.
Cheers,

Hello,
Is that a sub statute for the MP3 Trigger? looks much smaller and bigger SD slot...can you give me some details on that MP3 board.
thanks man,
i also want that battery set up, specs please? sorry im a complete noob..and im working on my artoo now. is that a volt reader? on the battery?
Hey Hoolagen1,
That is the "older" MDFLY 40 MP3 Serial Module. It's very basic, handles only 40 MP3's, and is limited for triggers. Perfect for small simple projects like R2, Wall-E, Omnibots.
It's cheap ($20 bucks or so). The newer version uses a Micro-SD and has some better features.

I'm new to the world of LiPo batteries myself. I've been playing around with (2) versions. One is a 11.1V (1500mAH) and the other is a 7.4V (1000mAH). They both seem to run fine with the EZ-B. The 11.1V runs the voltage regulators a little warm but nothing overly excessive.
I haven't done a full run-time test on them yet. Unofficially I got about 45 minutes playing around with R2, but did not have the MP3 module running at that time. Once I get some more time I'll do a full comparison.
I'll probably give the 2200mAH a try next go around as well.
LiPo's I'm told are very touchy, if the cells get drained below a certain voltage they sometimes don't recover well. I have some cheapy cheap E-Bay low battery warning modules plugged in. They start to beep prior to the cell voltage getting too low.
I got all my batteries here -> solarbotics.com/search/lipo/
Hope this helps?
Added LED's to the dome tonight.
Red & Blue for the PSI and a white LED for the Holo. I'll add a 3mm blue LED to the lower power coupler tomorrow.
Quick vid of R2, Random audio is on then I initiate the R2 short circuit script.
Cheers!

Baby slip rings arrived today. Going to work on adding one to R2's body/dome. This will allow me to send power and EZ-B control up to the dome while it's spinning 360.
These are about 4 times smaller than the slip ring I use in my big R2.
wait. whaaaaaaaaaat? do those things spin? im working my r2 now too.
sorry, lame brain cant understand.
