    Oh, I like breakers. The additional circuits I've installed -- mostly having to do with the auxiliary battery system -- are protected by thermal breakers. But I haven't replaced any OEM fuses with breakers; I'm doing my best not to overload anything, so none have popped in normal use.

    I'm sort of old-school when it comes to fuses and breakers. I think they pop when something is wrong. If one pops because of an overload, I need an added circuit or to do load balancing. If one pops from a short, I need to find the short.

    When the Accessory circuit fuse started popping, I knew I'd screwed something up. It acted like a short, because sometimes it popped as soon as I loaded the circuit. It was really irritating, doing without that circuit, because it powers the cruise control, the radio, and the radar detector. I was actively hunting for the problem, taking stuff apart and trying to track it down.

    Since the problem was intermittent, I could have used a breaker, but putting a breaker in there would have made it a back-of-mind issue, easy to ignore. I figured it wasn't going to get better, and, if I let the wire heat up repeatedly, I might have had a fire. Fire is a bad thing.

    So -- no breaker.

    Now that I've found the problem, I have no regrets about doing it the hard way. No fire is a good thing.

    Security System vs. Robot

    I have to admit, when I couldn't figure out what was causing that short in my system, I was even starting to question my ability to pull this installation off. Now that I've found the short, and especially now that I see it was such a simple thing, that confidence bobble is past me. I'm ready to move on to new challenges, and the Arduino-based vehicle security system is high on that list.

    To get to the security system, we're taking a dual-track approach. My granddaughter is 7; she's interested in what we're doing with the Arduino, and we both like the idea of drawing her into it. Still, a vehicle security system isn't going to hold her attention very long, simply because it doesn't "do" anything. But Josh mentioned a robot, and that grabbed her.

    So, while we learn how to make the Arduino do what we want it to do, we'll aim our work at building a robot. And most of what we learn will apply to the security system -- and to things we haven't even thought of, yet.

    NOTE: For real top-level security, what I'd like is a trunk monkey, but it isn't an option on the Scion.

    I'm watching the developments in work being done by bugbyte and kev000 on connecting their cars to the cloud. I want our cars connected, too, and these guys are leading the way.

    Meanwhile, we're working out robot -- or maybe even Battlebot -- stuff. In the security area, I'm thinking up ideas like setting up some contacts in the theft-worthy stuff, connecting them to capacitors, and making sure that trying to steal things would be "exciting" for the thieves. Of course, to keep from having the jerks try to sue us for their pain and suffering (which I'd hope to capture on video), we'll have to find some sort of reasonable application for those devices.

    Hmmmm. That could be good stuff to roll into the robot, too . . . this is fun stuff.

    We're working on the cloud stuff, yup. For the Arduino, consider a Sheeva for an always on computer hooked to the aux batts and use an iPhone to control stuff via a web page and php script.

    Why not spring for the trunk monkey? They are fairly low-maintenance... That is, until they start flinging... Nevermind...
    I have bad luck with vehicles...

    We're almost there. We have all the pieces except the Sheeva. But, while I can see the goal, I'm having a tough time seeing the path to it. I'm not Linux literate, nor am I much of a programmer. Well, I did that eons ago, but it would take a jackhammer to knock the rust off my programming skills. I'm not even sure I want to learn Linux, although the advent of the Android phone certainly makes that one route to a tantalizing future.

    For now, I'm looking around at other options to see what's practical, slurping up the information you and kev000 are putting out, and learning to think like an Arduino. We'll get there.

    . . . and I'm still finishing off the basics of the carPC installation I've started. The finish line is it sight, with that.

    Laying Out the PC Control Panel

    I like switches and lights, and I like control panels, so I plan to build a control panel for the carPC. I've been collecting the parts. I hate to throw decent parts away, so I have several sets of LEDs from retired PC cases, and found most of the switches -- all mini rocker On/Off switches -- in dead power supplies. They look like this illustration from Mouser.com, though they're all black:


    The reset switch, though, is an oddball; it looks exactly like the others, but it's Momentary On/Off. It came from a retired server.

    In the current plan, the 7-inch panel has PC power switch, PC power LED and PC disk activity LED, PC Reset switch, touchscreen power switch, radar detector power source switch, and the five-slot side of the 7-port powered hub.

    The PC power switch controls the signal from the Ignition to the M4-ATX power supply. The radar detector power source switch operates through a 5-pole relay; while it's just an Off/On switch, the relay causes it to act as an On/On switch, feeding power from the ignition line in the On position (so it operates only when the ignition is on), and from the auxiliary battery in the Off position.

    Stealth Location
    While I like the idea of switches and lights, I know they attract the attention of thieves, and indicate something possibly worth stealing. So this panel will go down under the relocated head unit, where it's visible only if you're looking for it. The casual observer -- especially someone looking in the tinted windows -- probably won't even see it.

    Stealth Lighting, Too
    I want the panel lighted when I'm in the car, but, again, I know lights attract the attention of thieves, so this panel will go dark when the ignition goes off. I want to kill not just the lights under the switch labels, but even the LEDs. No driver? No lights. I'll use relays to control the LEDs, so they'll operate normally when the ignition is on, but will stay dark with the ignition off, even though the PC may be operating.

    Car Care Day

    After a wait of several weeks, the Scion gets its replacement tire today. The old one is a lovely display piece on the outside, but it's damaged beyond repair: a deep punch in the tread and a damaged sidewall. With only 7,000 miles on it, it looks nearly new. Sad to see it go, but there's nothing we can do to salvage it. It'll become one the more attractive parts of an artificial reef, I suppose. I had to wait a while to get the tires originally, and it took a while to get the replacement. It's a good thing I had the stock wheel and tire to use in the meantime -- I'd have hated to drive on the little space-saver bagel that's the OEM spare.

    Last weekend the Scion got new sparkplugs, and that helped put some zip back into climbing around the mountain roads here. Stock gap is .031 to .032 inch (~0.8mm), and the plugs that came out, after 88,000 miles, gapped as low as .040 (~1mm) and as high as .053 (~1.3mm): way off.

    After I get back from the tire shop, there's some computer work I have to do, and then I'm hoping I'll get to finish putting the PC back in the dash. Yeehaw!

    The new tire is on, and, boy, is it a better-handling car, again. I came home and did computer work 'til my eyes crossed and my mouse muscles got frazzled.

    Then it was time for car work. We pulled out the heater and warmed up the garage, so it's pretty nice working in there.

    All the wiring issues are cleared up, soldered up, or eliminated. The seat is reinstalled. The switches are installed at the ends of their wires, although the control panel isn't designed or built yet. Now I'm headed back down to get the PC in the dash. With a little luck and perseverance, I'll be back in with a big grin on my face.

    Another Session of "No Joy in Mudville"

    I had another very frustrating session of trying to ease the PC into the dash, complete with several cable placement issues. I got it all in and running, and found the USB connection for the keyboard had pulled out of place. There's no way to fix that but to take the PC back out and reconnect it.

    I decided to backtrack, look at the situation, and decide what I can do to fix it. I took the PC back out of the dash and disassembled it to its basic components: the side panels, the top panel where the PSU mounts, the bottom panel where the hard drive mounts, and the mainboard, fastened to the sides between the top and bottom panels.

    After some noodling, I decided that a semi-redesign of the case is relatively easy and pretty much necessary. To make the change, I'll need to produce two side panels and two angle mounts for the bottom panel -- an hour or two of forming and drilling. Then I can turn the mainboard around and have the cables facing the passenger compartment, instead of the dash. With that new configuration, I can put the cables in place, slide the PC into the dash, and attach the cables right there on the dashboard end of the PC. There shouldn't be any problem getting the PC into position if I place the cables properly.

    So this is a temporary setback, but I expect it will be very worthwhile to make this change. I have a bunch more computer work to do (for work, not the car) before I can tackle the new panels, but I hope to get started on them today.
