I was out of town for a bit (work), so now I'm back and I'll show you what I've gotten done over the last week or so.
I started by mounting outer ankle covers (added just a little more metal to fill in some voids)
With those mounted I focused in on the Center ankle, for it to be mounted I had to cut a recess in the bottom of the frame (about 1/4" of wood was removed from the 3/4" plywood), also I filled the area around the perimeter full of expanding foam ( the .04" styrene was sagging allot, and any bump made it flex). Then the Ankle over was pop riveted into place.
Sorry, It was getting ready to rain when I did the cutting and mounting, so I was in a hurry and forgot to snap pics till I was done.
I also gave in and ordered a 24 contact Slipring (straight from China...that was fun). The Slip ring allows electrical connections to remain constant even when the parts are spinning. With 2Amps max per trace I'll end up using about 21 of the 24 contact straight out of the box, this and signal to noise ratio is why I gave up on building my own.
This thing has nice gold contacts inside, so I can run that USB web cam through it :) and some Serial communication to the logics up there. To make removing the dome less of an issue I attached a DB25 to one side of the slipring.
Getting all these wires hooked up and tested is an on going process so expect to see more of it soon.
I also recut that Fan guard that I messed up, took way less time this go. Still need to file the saw marks out and make it all purrdy but it's getting there.
While I was cutting stuff I took a few minutes to cut a lid out for the Motherboard protection system....Nothing fancy...
We all know that R2-D2 makes sounds, Well So will R2-SRV to do that we need Speakers, well the speakers need mounts that was the next task tackled. I got 1 cut out of 18gauge steel that I have...This stuff is tough to cut with a scroll saw (inside cut can't be done easily with tin snips).
Looks nice, Lets test fit it with the speaker.
Now that I know it really fits, I'll drill the holes in the corners for mounting screws and cut out the second one.
I've got a bit more fab to finish up, I think I'm down to 6-10 parts left to make, and mount the front doors and we're ready for paint (ok,I know I still need to make the Mp3 player work, and mount the projector, and make the 12V battery charger but this can be worked on when the paints wet....I'm trying to schedule it all) Plus with g00se's I7 threating to be at MML too, I need to kick it up a notch ( what, I love the idea of I7 and R2 Racing at MML....any betters out there???) (G00se's work log is @ Gruntville.com)
Please let me know what you think. I also know it's been a long time since I posted a pic of the complete R2 (or at least everything I've got done)... That's coming, I'll post one before paint, then I'll post one after we get to MML when the paint's done...what can't reveal everything too early.

Welcome once again to This old Droid.....
This week we'll get a glimpse of one of the last steel details as it's starting. We'll also make an astablemultivibrator.... Fun! Also there will be a revisit to the motherboard protection system.. Now lets go to the shop.
I've been working on finishing up the fab of all the steel details (so the welder can be switched over to Aluminum welding), I'm down to the last 4 it's really just 4 of the same part, It's a detail on the side of the foot. Here's what I've got done (still more work needed) It's just the face plate.
There will be more work completed on this part this week.
Most of my time was spent working on the more "Fun" part, the lighting.
Their is a yellow/ green oscillating light on the back of the dome. For that I made an astablemultivibrator circuit (big name little circuit, has 2 transistors, 2 capacitors, and 4 resistors in it) a home made PCB makes it a nice little package (the LEDs in the picture are 3mm in Dia)
With the board made and soldered up, I needed some thing to house it.
The white PVC plumbing fittings help space the lights away from the plexi lens in the dome (just a piece of lexan lightly wet sanded 800grit inside and out) so that there are no hot (bright) spots on the lens. Here's what this crazy thing looks like assembled.
When mounted in the dome you get an effect like this Video of Lights running in the dome! (file is about 17Mb)
Now I know that you've seen the front logic displays but here's a video of them in action Video of Front Logics running in the dome!
Now that I'm done showing off the eye candy, lets see what’s up with the Motherboard protection system.
The power / reset switches are test fitted in the enclosure (you can also see the holes for the Wireless network adapters antenna near the bottom right corner).
Also the Fan hole has been drilled.
I know I know you want to see that Sweet R2 Fan guard mounted over that hole..... OK, stop twisting my arm! :)
That's where I'm at currently, got allot of work to complete and no time to do it! so keep watching I think it's going to get fun around here!
CrazyBillyBob
Damnit CBB! You hurry up and finish that little critter, ya hear? :p
-Dave
Dave,
I'm trying, If work would stop getting in my way :)
IT WILL BE DONE BEFORE JUNE 21, 2007 (even if I don't sleep for the last week!!)
By the way, which Pic uP do you recomed learning on? I think I'm going to take the plung (picked up a good book on programing them recently on work trip).
Just want to make it easy on my self.
CrazyBillyBob
I learned PIC Assembly on a standard 8 pin PIC, doing some basic things like learning how to use the variable input/output to drive 8 LED's from 4 lines and so forth. A small and simple PIC will make life easier.
All you have to remember is that it uses Harvard Architecture instead of the John von Neumann model. Once you figure that out, it suddenly becomes much easier!
Good luck dude! It's been nearly a year and a half since i did any programming lower than C, so i feel rusty now. :(
-Dave
don't worry about screwing up the architecture.....It's been so long since I wrote any assembly code for an Intel based system....I forget it....the basics are still there mov regA to Workreg and regc to workreg place result in regD
That I remember syntax and commands ...aAaaaa nope. The whole moveing that program from one mem page to the other, and remembering the stack isn't accessable from the second page.....???:? That's where it gets tricky.
I just ordered a 28 pin....I think 20 I/o picXXF57XX it's referanced in this book, I'm going to try and run it on a 16Mhz crytal Hope it's not too fast for me :)
I'm sure as I go I'll be asking for help. Think I'll us one in my next mod :) (still don't know what that will be at this point)
CrazyBillyBob
Spurred along by G00se's I7W7 progress, and the impending Droid Race at MML, It's time for a little update
The Half-moon details for the feet are finally fully welded.
The half-moon details will be mounted on the sides of the feet Like this (minus the hand ;) )
Just need to drill a couple holes in the foot for mounting.
With that done all of the large pieces are fabbed... I can finish mounting things and start the painting process.
For Painting all of the wood parts get a thin coat of bondo, and/or glazing putty, This hides the wood grain and gives me a smooth surface to paint on.
Here you can see one arm coated in putty the other has been primed and sanded, a few spots have been filled in again....Rinse and repeat!
The booster covers here have been puttied, sanded and primed. The one on the left is all ready for paint, the one on the right needs a few last details glued on and some spots fixed and a few more coats of primer.
While the paint was drying (no I didn't watch it much this time!) The Slip ring was mounted into the frame.
I also started getting the Dome Motor ready to install, It's out of the automatic seat belt that was in my wife's car. Don't worry she doesn't drive it anymore......My Mother in law does :)
I've also been working on some more of the Electronics, no fun pics just designs and what not. Also a few projects around the house, and the fact that I've gotten a new job, back in Ohio that I start soon (about 5.5 hours from home) have kept me busy. I'll be hitting R2 hard for the next few weeks as I have some time off coming...
As always let me know what you think.
CrazyBillyBob
Thanks, Minty. Hopefully I'll have something more for you to watch soon!
CrazyBillyBob
What??? An Update..... About Time!!! :)
It's been a while since I got around to posting an update so some of this is a bit dated, but you all have stuck with me this far I'll not start skimping out now!
The first group here is the end of the mad dash to MML this year.
The Big thing was the Paint Job on the body, Legs, and feet.
To start it off I masked off the inside of the droid shell.
Once everything was masked off the painting started... After 2 and 1/2 cans of Krylon fusion (and a few hours of drying time) R2's body looks...well white (it's not really white, it's a bit offwhite but the camera adjusts to make it look white)
I also found some Great stuff for cases, It's Cheap, looks good and holds paint well... What is this miracle stuff?
That's right Aluminum window screen.
This one layer painted and cut to size.
Here's 2 layers of screen glued to the back of the aluminum grill cover. My two Speakers are mounted behind the grills one on each side of the droid's body. I can see this stuff showing up in some of my other mods where I would have used modders mesh before.
Then there's the night before MML (we took off @ 3am Thursday...I didn't sleep at all that night)
This was what the inside of my friend Cytog's garage looked like till about 2:59am :)
There was also some work completed at MML (some Wiring finished..and some repairs from shipping damage)
Target Practice Is lending a helping hand here too.
At this point your thinking WHY!!!
Well here's a few pics from MML6, all I can say is that Running R2 around in a crowd is FUN!!
R2's first kiss.
Some Jedi younglings and their Masters.
Then there's always the Grunts :)
There's also the Droid Races too!
(a special thanks to Cytog... the last few pics were taken by him)
Well after recovering from MML6 I started the push to Finish the last remaining things on R2-SRV In preparation for Showdown LAN 2007 - Indy . Sept. 14-16 2007. The biggest thing not done now is the Dome Rotation.
The first step to getting the dome to rotate is to get the drive wheel mounted on the motor shaft.....
For that you need a shaft adapter (a chunk of metal that is as big around as the hole in the middle of the drive wheel and has a hole in it as big as the motor shaft) how do you get one of these? Well I took a Brass Blank about 1.5 inches around
Added a little Lathe (8x12" model)
Then add in a bored 55 year old father (recovering from a kidney removal) .... Sorry the Old guy is camera shy :)
Mix all that up and leave for work one morning.... When you get home some 8-9 hours later... you have a bored 55 year old guy with this in his hands
With a little work (drilling and taping a setscrew hole) and mounting the wheel you get this ...
Then your company sends you to Texas for 10 days....30 days later I'm still here So I've gotten nothing more done :( But the up side you all will get more R2-Srv updates in the future! (hay, act more excited!!)
Time to pack and hope my flight home is not delayed!! (Edit:....Made It home!!!)
CrazyBillyBob
just the other day i was sitting here thinking hmm...i wonder where CBB has been and what has he done with r2
glad to see you are keepin this alive and i cant wait to see how it turns out!
I'm not sure how Texas was.... All I saw for the most part was the Court House / Police station (where I worked) and the Hotel (where I worked some more...oh and slept a bit).... The Only time I was out in the city was for lunch.... one of the guys I was working with there took me to all kinds of places...good Food !!!Quote:

Try very hard to get the second... "Special Edition" Feature in place.
Also get the weathering done.
A much smaller list then before :)
