    RepRap Meetup

    As expected, the RepRap session was very, very interesting. If you aren't familiar with the concept of Rapid Prototyping, take some time to look through RepRap.org. You could also Google "3D parts printer" for a look at both commercial systems and hobbyist-level devices.

    Rapid prototyping uses a 3D parts "printer", and works as if an inkjet head laid down a layer of plastic instead of ink, then moved up a bit and deposited the next layer, and kept going until there's a finished part.

    Johnny Russell and his team from ultimachine.com of South Pittsburg, Tennessee, brought down two machines. Our group got to see a MakerBot Cupcake CNC machine in action, and we got to watch some of the testing as a newly built RepRap Mendel was being aligned and checked as it was readied for its first run. The Mendel was built using parts produced on the MakerBot. Here's an image of the MakerBot:

    Where commercial systems cost tens of thousands of dollars, the whole Cupcake CNC device retails for $750. There are a few extras necessary to make it work -- downloadable software, cables, some tools to construct it, and your PC. It takes a while to assemble, and there's a little soldering to do. But this is a hobbyist-level tool. If you're interested, there are websites full of information, newsreader feeds, and videos to watch.

    I think rapid prototyping is going to come on strong. Johnny says there probably are over 2500 consumer-level machines around the world in various stages of construction, and several hundred already in action. I'm pretty sure we can use a system like this at work to produce parts that are hard or impossible to find. I could see us (1) ordering a MakerBot kit, (2) starting to assemble the pieces needed for a RepRap Mendel, or (3) both. The next batch of MakerBot kits won't ship for about 45 days, and there's no timeframe on when we could gather enough parts to build a RepRap Mendel, because they're still so hard to come by.

    I haven't come up with any parts for the carPC that would benefit from this. However, as the tools and the size of parts that can be produced gets larger, I can see there could be a nearly plug-and-play system to print complete bezels for dashboards, with all the tabs and fastener points built in. Initially, finish would be an issue, but I suspect that there will come a time when there will be multiple heads; a fine head would be used to print the surface areas, and a coarse head would be used for the structural parts. That capability might come from a variable-opening head, or from varying the travel speed of the head, but I'll leave such stuff to the extruder engineers.

    We would also need to explore methods for getting the parts we need into some workable CAD format for MakerBot production. There are some open source 3D scanner projects in the works. Here's MakerBot's link to information on that area. You could Google "3D scanner", too.

    We have plenty of projects to keep us busy, but this looks too interesting to pass up. We're not in a rush, but I'd like to get involved in this. The meetup was just the first step.

    USB Bracket Completed

    This is the mounting bracket for the USB ports that will sit in the cable bay of the chassis, up near the top:



    Click images to enlarge.

    Here's a look at it from the bottom . . .


    This part was once a flat piece of aluminum that I bent into an aluminum angle with the lightweight metal bender. I could just as easily have used store-bought aluminum angle, but I didn't have any handy. On each end, I cut one side of the angle off, then used the vise to bend the remaining side around for a mounting flange.

    I drilled the eight holes for the mounting screws, and then drilled four 1/4-inch (~6mm) holes for the ports. I rough-opened the port holes to 1/4 x 9/16 inch (~6 x 14mm) with a Dremel-type cutting wheel on a power drill, and used a small triangular hand file for the finish work.

    Here's a closer look at the end detail:


    This isn't a part that anyone is going to see, so I wasn't all that precise in filing the slots for the USB ports. I cleaned all the edges up with the small file. When I was done, I drilled mounting holes in the end, and punched matching holes in the chassis side panels.

    Once again, the punch was far cleaner than the drill. Instead of completely disassembling the chassis to keep from getting grill chips in the electronics, I just took out the two screws holding the rear mainboard mounts to make space for the punch. It left four little discs in my hand, and there was no cleanup needed on the side panels.

    Next, I'll fasten the bracket into the chassis and get the PC assembled and ready for installation.

    PC Assembled

    Here's everything in place, including the USB mounting bracket. This is the end I'll see when it's installed in the dash.



    Click image to enlarge.

    The USB bracket sits up pretty close to the chassis fans, and will probably impede airflow somewhat, but the fans are far bigger than necessary, so I don't ever expect heat to be an issue.

    The cable connections are for system power (the big gray one), the switch panel (front left -- goes to power LED, HDD activity LED, and reset switch), the 12V power connector (front right -- goes to two hubs, the DVD and the touchscreen), and DVD data (barely visible, lower center, just to the left of the hard drive). The small black cable running up the middle is power for the 12V chassis fans.

    Fit Check

    I pulled all the wires out of the way and slipped the revised chassis into the dash. It fits in there very nicely, about 1/2 inch (~13mm) deeper than before, and it appears that everything will connect up easily. Because it fit so well, there are some significant changes I've made in the wiring, and every one was a simplification:
    • In my last change to the PC's power cables -- an attempt to make them easier to work with in the previous installation -- I added a long extension to the hard drive cable so I could get the 12V connections deep in the dash. Now, with the mainboard turned around, I've taken that long extension off, and can use a stock 1-into-2 plug so the power cables attach right at the front of the dashboard. Less cable, less clutter.
    • I rewired the power plug for the 12V chassis fans so it plugs into the 12V drive power system.
    • I rerouted the power head so it comes up the lower console and enters the bottom area of the PC bay at the dash end, instead of way inside the dash; it will fit better this way, and make for a cleaner run; I'll have some extra cable to stash.
    • I separated the USB cables -- removing the snakeskin bundling I did before -- and ran most of them up from the bottom, rather than deep in the dash.
    • I pulled the video cable completely out of the dash; only the extra length I have needs to go in the dash. My sole complaint about the Lilliput is that it uses oddball connectors, and it would not be an easy task to shorten the cable; I only need about an 8 inches (~20cm) of cable, and I have many feet.
    • I ran the sound cable up from the bottom instead of inside the dash; it plugs into the OEM auxiliary sound port in the console, and now the cable I have is plenty long enough; I was going to need an extension, before.
    • I rerouted the indicator LED and switch wires; because they have a much shorter distance to go, I'll have plenty of wire length when I build the sub-bezel for them.

    When I think of all the hoops I jumped through to get this working before, I can see that, if I had built the chassis this way in the first place, I'd be way ahead of where I am now.

    Fit Check Image

    Here's how the new version of the chassis fits in the dash:



    Click image to enlarge.

    This is very similar to the previous fit, but it's a little deeper in the dash. It requires that I reconfigure the mounting system, and I had to do a lot of cable rerouting. So far, it's better in every way than the previous design.

    The next task is to figure the best way to mount the chassis.

    Mounting the Chassis

    The current mounting brackets for the PC couldn't get much simpler: they're just four short pieces of aluminum angle, two riveted to each side panel. The holes in them match the OEM mounting holes in the dash. In the redesign process, I considered several other ways to mount the chassis.

    The existing brackets let me adjust the PC to any position before making the holes for them in the side panels. But I'll have to do a complete test installation and mark the hole positions on the panels, and then uninstall, disassemble, drill or punch the holes, rivet the brackets on, reassemble, and reinstall. I wondered if I could avoid all that by designing an adjustable mount.

    I came up with some nifty design concepts, but none were simple. Some got very complex, requiring a bender and some educated guessing to get things just right. I even thought up a one-piece per side bracket with curved slots, but I'm not sure I could make it without Herculean effort and hours of filing.

    In the end, I figured out that the install - mark - uninstall - disassemble - drill/punch - fasten - reassemble - re-install process happens only one time. After that, it would be uninstall - reinstall. While the other brackets might avoid that one-time process, they're all more complex, harder to get right, and more time-consuming to manufacture than the proven system I'm using.

    Going on that theory, I marked the chassis for the existing mounting brackets while it was in the dash. With the new design, the lower mounts can be eliminated. In the new, deeper location, the lower edge of the chassis will sit right on the dash ledge that forms the bottom of the double-DIN bay. Screwing down the two upper mounts should hold it in place just fine.

    Funny thing -- the four mounts that couldn't get much simpler have gotten simpler -- now there are just two of them.

    Then it got even better: I looked at the location of the holes, and all I had to do was pull the chassis out of the dash, use that slick little hand punch to punch the two holes -- no disassembly required -- and the job was done.

    I need to round the shape of the mounts a little with a file, and they'll be ready to rivet in place.

    Final Tasks Before Installing

    There were a few last things to do:
    • Checked the polarity on the PSU wiring I replaced; it was fine.
    • Did the rerouting and simplifying of cables, found ways to stash the extra lengths of wire, and made sure everything was just long enough.
    • Riveted the mount brackets to the sides of the chassis.
    • Made all the attachments in the chassis, and buttoned her up for installation.
    • Did a bench test to be sure everything was working in a controlled environment.

    There were some updates to AVG and XP, but I didn't download them; it'll be a good test in the car to do the update there, wirelessly.

    Everything is good to go, so the next job is installation.

    She's In. She's Running.

    This time the installation went the way it was supposed to: no grunting, no frustration, no muttering. I spent quite a bit of time rerouting cables, then discovered an even better route through the dashboard, and re-rerouted many of them. In the end, I wound up with a nice, clean installation with carefully routed wires -- some of which still have to be bundled -- and good connections.

    There was a good reason for the rerouting. On Friday morning, I discovered that the defrost setting on the heater was suddenly unavailable. The control is a mechanical one -- a cable connected to a knob. I couldn't turn the knob to the defrost setting, and I figured something could be blocking the control in the dash -- maybe a cable got in the path of the mechanism -- or I'd somehow dropped something into the duct, and it was blocking the door that makes the air change direction. Job One was to get that fixed before installing. It turned out to be pretty easy: I had temporarily moved the power cable in getting ready to install, and it had blocked the motion of the door control.

    While I was on my back under the dash, I spent some time investigating other cable paths. I discovered a new routing that cleans up the cabling and allows good access to an area in the dash where I can bundle up extra cable lengths and store them neatly.

    So far, everything works. I'll take her on a shakedown cruise tonight after everything is cleaned up and the tools are all back in place.

    And I'll get some pictures of the wired system.

    Feels good to get to this place -- like an early Christmas present to myself.

    Yea..... yours is getting close. A lot closer then mine. I have so many aspects that i have to tackle that now i am seeing stars, literally. I may have to push my beginning of the year finish, all the way to the middle. Everything is just so chaotic. I tried to tackle to much at once. I'm glad you didn't make the same mistake. You were so meticulous with your planning. I wish I had that trait.

    I've started several times to expand the project, and sometimes I've been able to pull back, realizing I need to finish one part before expanding another. But I've still changed the PC completely twice, changed the screen twice, rebuilt the chassis once, changed the screen mount twice just for the latest screen, and added the auxiliary battery system.

    It's something of a relief to see it all beginning to work in concert. I christened it with a 500-mile trip, and some of the roads weren't very smooth. The system did fine.

    There's a lot to do, yet -- not just tweaks, but basic stuff like the bezel. One thing I have to do is get pictures in decent light.
