March 2007 Summary and R2-CCA Get Together

Last weekend was the R2-CCA event at Ed’s place in Elk Grove near Sacramento, and I thought I’d best do a quick write up while I remember.

It was a long drive from the Bay Area, but well worth it. I got to meet some fellow builders and talk over some road blocks and decision I need to make.

I packed up a bunch of parts at random to show and talk over, including my dome and the new persicope lifter kit from Daniel, my new legs from JAG along with all the leg detail parts.

Like an idiot I forgot my camera, so sorry there’s no photos of the event.

There were four R2 builders in a attendance, Ed Wamser, Ryan Goff, Gerard Fejardo and myself. There was a also bunch of friends from the 501st that I hadn’t seen in a very long time, so it was good to catch up.

I was suitable impressed on how much work Ed and Ryan had put into their R2’s. I wish I was that far along in my build Ed is very close to finishing.

After a long day and lots of talk I now I’ve cleared some things that were bothering me and stopping me moving forward –

  • Dome – I’ve cut out most of my dome and can attach most things, like the Holo Projectors etc. But I’d recently gotten the new one piece AL Front Logic Kit, which requires me to re-do/pull apart my B&J Front Logic LED Kit to make room. It also requires a big square cut in the dome. I can’t see me doing either, and the consensus was to try and use the older separate Logic Surrounds. Another issue with the dome was I was in a short of catch-22 with assembling it before I got my frame. I had thought that I needed to wait before I could attach my Periscope Kit, Rockler Bearing, etc. But Gerard explained how I can work around it. And I’m confident I can now move forward with finishing the dome w/o worrying about aligning things later.
  • Rockler Bearing – After seeing Ed and Ryan’s setups, I’m pretty confident on how I’ll mount the bearing and dome lifter plate from Dan.
  • No 2-3-2 for now – More complicated and unproven on heavy droids. I have the sat motors, but I’m still going to pass for now.
  • Paint – I also brought along my paint samples. Everyone who’d seen “Krider Blue” thought I was pretty close. Ed used to work in the automotive paint industry and had some good tips too.
  • JAG Legs – Gerard had brought his fully assembled JAG legs, and I got some great tips on how to assemble mine. I’ll be documenting this later.
  • Drive System – I’ve decided to stick with the JAG drive system using the NPC-2212 motors. Dan had mentioned some custom motors from NPC that maybe more suitable, but they work out to be close to twice the price, but the drive system should be simpler if and when it’s made. However, when I factored in spare motors, and the possible wait for Daniel, then the JAG system comes out cheaper. ** See more below **

I’m sure there was more things we’d talked about 🙂

When I got home I just dumped everything on my workbench, and only tonite did I get around to sorting things out. What surprised me was how much stuff I’ve accumulated in such a short period of time. I’d only really started the project in earnest in November 2006. I was going to list what new parts I’d gotten in the last month, but it’s easier to say what I’m missing.

On Order/Arriving Soon

  • JAG Outer Ankles
  • JAG Outer Feet
  • JAG Drive System
  • McMaster’s Octagon Ports
  • Waterset Ankle Cylinders and Wedges
  • WARR Battery Harnesses
  • DanS Power Distribution Board

Needed

  • Center Foot (run planned)
  • AL Frame (run planned)

And that’s it. I’m also holding off from buying the following as I don’t need to spend th cash right now –

  • CF3 Sound Board
  • NPC-2212 Motors
  • Battery Charging System
  • Speed Controllers

So as you can seem I’m very close to having most of the parts.

It’s a shame I do not have everything in hand as I’m pretty sure I could get an unpainted RC Droid ready for C4. Maybe I’ll get the dome done in time to bring down.

I was also hoping to get to LA this weekend for the Science Center R2 meetup, but it’s a long drive and it’ll be hard to get there by 11am without moving some other things I had planned. C4 is less than 60 days way now, so I’ll get to see a lot of the southern builders very soon.

This week I also got some of the surplus drive motors that are very close to the NPC-2212. All that’s missing is the extra mounting holes. Plan will be to use these as spares and reduce the cost of buying spare NPC-2212 motors.

That’s it for now. Nothing major planned this weekend coming up now that I’m not going to LA, so I should get to R2 at least one of the days.

February 2007 Summary

I just realized that it’s been a while since I’ve blogged – Work has been busy and I have a trip planned for next week, so R2 progress has been slow. I’ve also been blocked waiting on a few dome parts, so I’ve been in planning mode more than anything or tinkering with electronics.

The good news is that I’ve now got the majority of parts either in hand, on order or know that there will be runs very soon. Unfortunately I’m still waiting on the aluminum frame run to be announced. Without a frame, it’s hard to work on anything other than the dome, which is all cut out and waiting parts.

The Rear and Front Logic Surrounds from Wayne and Doug, and the RobArt hinges for the dome panels should be arriving in the next week. Once I get them I should be able to move forward and glue the dome together and get some of the electronics installed and maybe even paint the dome.

The front logic from Doug is one piece that replaces the whole front logic panel on the R&J dome and has easy mounting for the electronics and bezels. I’d originally planned on going with the traditional two piece surrounds (which I have in hand), but I really like the one piece design.

I was tempted to start painting the dome and polishing some pieces last week, but this would make the dome harder to handle and I could easily see me having to repaint things after I’m done installing the electronics, hinges, periscope kit etc. It’s also been rainy the last few weeks which would effect the paint process.

Other good news is I’ve done some programming test on the Vex controllers and successfully tested my idea of using a cheap 12 channel RF remote (that people are using to trigger R2 sounds) to allow me to expand the number of channels/functions on the basic Vex RC transmitter.

As I’ve mentioned before I’m hoping to have more than simple forward/reverse and dome rotation, and by my estimate I can easily see me needing to control 15+ devices in the future (lights, motors, servos, doors/hatches, 2-3-2 etc.) , and from what I’ve read many of the builders who have a lot of things to control use expensive Futaba RC setups that can easily cost in excess of a $1,000. I’m hoping to get similar or better flexibility for less than $500 by using multiple Vex micro controllers, an RF remote and some C programming.

The plan is to use 2 Vex Micro controllers in the body giving me access to at least 16 motors or devices, and I’ll have a 3rd Vex in the Dome to control the things like periscope, lights and HP rotation/twitching. I guess I should draw up a diagram to try and explain all this and get it clear in my head 🙂

Oh! and while I remember, one of the catches on the Vex controllers is that they use male Futaba J-type connectors. From what I gather most other RC manufacturers use female plugs to connect servos/motors etc to the controllers, but the Vex uses male. Of course Vex Labs sells them, but like a lot of their accessories they’re really expensive. The good news is I found a place that sells Do-it-yourself kits to make your own Futaba J-plugs/connectors at a fraction of the cost.

So, this month has been more planning than anything. I’m hoping when I get back from my trip that in March I get more time to work on the dome.
