I have until next spring or so to get it completed. We are currently building a 73 dodge pick-up truck for competition next year out at the Bonneville Utah Salt Flats for speed week and in N.C. for the east coast speed trials. That way we can promote our webzine and so I can drive fast. (current record in this class is 139 mph, that was done two years ago in a 72 dodge pick up). We are set to compete in class "A". That means stock body and no fiberglass/ engine must be natural aspirated (no turbos/superchargers), gas fuel. The engine will be in the 8.2. litre (500 cubic inch) range. We recently started using FreeBSD here after attending Beyond HOPE. We would like to use FreeBSD to sample temperatures water, oil, tranny fluid, exhaust ports, intake etc., (tired of analog gauges), GPS and anything else that we or you can do with it. We want to be able to read all of these samples after each run so we can see exactly how the engine is performing. The other possibility is to have it output simultaneously to an all digital dash. We have already found a place that we can mail our 23 year old dash and get a brand new all digital dash built for us that will bolt back into the stock dashboard. We just aren't sure were to get parts. Our best guess is to use stuff that is used in the manufacturing industry that can be sampled by a FreeBSD machine or maybe even some modified SmartHouse stuff. We can do testing with a desktop, but ultimately we will need to use a mobile computer which I am sure we should be able to get at least temporarily from a sponsor. Currently we have Federal-Mogul sponsoring us with others pending. We will of course like to put the FreeBSD daemon on the side of the truck and help cross-promote the FreeBSD scene. Just let us know if anybody is interested, any help with industrial hardware will be greatly appreciated....and remember, never drive faster then your guardian angel can fly :) thanx, -cliff -------------------------------------------------------------------------- CLIFFSWORLD homepage------ "Open Throttle" web-zine----- Quake-Clan "RIP" homepage-------- box 1055, Maywood NJ, 07607-7055 fone 201-843-0936 PGP v5.0 public key available "Do not stare into the FDDI port with remaining eye" (Paraphrased from the Cisco 7206 installation guide).

I suggest you want to use standard automotive sensors, they will come in the right mechanical forms to fit the locations they are destined for. There's no magic to them, for the most part they are just a resistor that changes value over temperature or pressure. There may be a need for more exotic sensors in a few places, but you mostly will be sensing either resistance or voltage. For things like rpm you will be counting pulses. --- > We can do testing > with a desktop, but ultimately we will need to use a mobile computer which > I am sure we should be able to get at least temporarily from a sponsor. I don't see the need for a laptop, if thats what you mean by mobile. It wont be able to hold all the analog/digital cards you will want to use. And a truck must certainly have a place big enough to hold a standard (small) pc case. Consider making a custom case of clear/smoked plexiglass to show it off. Can the computer control the engine, etc. in this class? Or can it ONLY log data? If all it is allowed to do is log data I would consider placing a simple datalogger machine in the truck, then dump to a freebsd box in the pits via a network or port cable for ananlyis. Consider solid state disk and/or diskless for the truck if possible. A hard disk is asking for mechanical failure. --- > Currently we have Federal-Mogul sponsoring us with others pending.

I haven't noticed > anything wrong on the DOS side of the disk, but it just might not have > any bad-spots on that part of the disk. The error above doesn't really indicate a bad sector. It's odd though that the disk works under DOS, unless DOS doesn't use the interrupt for the disk but instead polls for status.

For sensors, you will want to talk first to your local speed shop. There's probably someone there with connections in the racing industry; failing that start going through the ads in the back of whatever speed -freak magazines you can find. Just off the top of my head, you'll probably be interested in: - inlet air temperature and pressure - exhaust temperature, pressure and oxygen concentration - knocking - timing advance & dwell - throttle position - engine RPM - fuel pressure & flow rate - oil pressure, temperature (engine, transmission, maybe diff) - tailshaft RPM (wheel speed) - ground speed (fifth wheel, ground doppler, other techniques?) - coolant temperature, pressure - outside air temperature - inertials (2D or 3D accelerometer) GPS might be useful depending on the length of the run; I suspect that its basic accuracy won't be good enough to give you useful figures. Watch out for fifth-wheel speed recorders; they have a tendancy to disintegrate under severe conditions. Will you be using an electronic ignition system, or the original Kettering hardware? If the former, you might want to look for one that supports a diagnostic/programing port so you can monitor and configure it. > We can do testing > with a desktop, but ultimately we will need to use a mobile computer which > I am sure we should be able to get at least temporarily from a sponsor. You should be able to find a 12 or 24VDC industrial chassis that'll take the CPU card and a couple of I/O cards; I'd anticipate you'd want either 3 or 4 slots all up; CPU, solid-state disk, Mixed-mode I/O, possibly more I/O. Someone like Industrial Computer Source or Advantech will do these for you. Steve's point about avoiding spinning disks is a good one; you might be lucky with good mountings and a 2.5" laptop drive, but I'd avoid it if at all possible. One approach to consider would be to boot from a solid-state disk and keep all your logged data in RAM until the end of the run, and then dump it to a laptop before you power down. > Currently we have Federal-Mogul sponsoring us with others pending.

Actually, GPS is *very* accurate. If you really want to do GPS, setup a stationary unit, and use the data collected from it. You can get better than 1-meter accuracy that way (differential GPS.) > Watch out for fifth-wheel speed recorders; they have a tendancy to > disintegrate under severe conditions.

A 24 port 10bt switch has much higher aggregate bandwith than a 100bt hub. The Cisco Catalyst 1900 is nice, and has 2 100bt ports for connection to the backbone. The maximum aggregate bandwidth of the Catalyst 1900 is 440mbs, while a 100bt hub is just 100mbs. > ron > > Ron Minnich |Java: an operating-system-independent, > rminnich@sarnoff.com |architecture-independent programming language > (609)-734-3120 |for Windows/95 and Windows/NT on the Pentium > ftp://ftp.sarnoff.com/pub/mnfs/www/docs/cluster.html Tom From owner-freebsd-hardware Mon Oct 6 12:36:44 1997 Return-Path: Received: (from root@localhost) by hub.freebsd.org (8.8.7/8.8.7) id MAA22142 for hardware-outgoing; Mon, 6 Oct 1997 12:36:44 -0700 (PDT) (envelope-from owner-freebsd-hardware) Received: from earth.mat.net (chuckr@earth.mat.net [206.246.122.2]) by hub.freebsd.org (8.8.7/8.8.7) with ESMTP id MAA22133 for ; Mon, 6 Oct 1997 12:36:36 -0700 (PDT) (envelope-from chuckr@mat.net) Received: from localhost (chuckr@localhost) by earth.mat.net (8.8.7/8.6.12) with SMTP id PAA04985; Mon, 6 Oct 1997 15:36:23 -0400 (EDT) Date: Mon, 6 Oct 1997 15:35:29 -0400 (EDT) From: Chuck Robey To: "Christopher R.

It's really not FreeBSD related, but I'm in kind of a jam, and I hope someone can help me. I recently bought an M-Tech R534F mb with Cyrix P200+ and generic SDRAM. Apparently this SDRAM isn't happy on the board. It crashed every time when I tried to install from CD with SDRAM but the install goes OK with simms. (I assume the RAM is the problem since I saw the same behavior with another mb). My vendor will swap the SDRAM for Hyundai or Samsung electronics, but will not refund my full purchase price (I bought this two months ago), so I'd rather go with the swap than take a $25 dollar loss. Does anyone have any experience with these mobo/proc/memory combos? Any recommendations? Thanks.

Inlet air moisture content is pretty easy too. As for "dreaming", none of the sensors above are particularly difficult to implement or manage, except for the ground speed measurement and you killed that one with the DGPS suggestion.

You will want a decent wireless radio link between the truck and your base station to run the DGPS data (from memory the Rockwell modules want 9600 bps) over. A relatively cheap shorthaul wireless modem set should give you enough to run PPP over. You could use this for realtime telemetry. 8) With DGPS you get real groundspeed, from which you can calculate your acceleration. This lets you forget about inertials, as well as calculating drive slip (fairly important if you're worried about running from a standing start). > > Watch out for fifth-wheel speed recorders; they have a tendancy to > > disintegrate under severe conditions. > > Not only that, they tend to slow you down. :) This is when they're working, or after they've become small rototillers dragging clumps of the roadway behind you? mike From owner-freebsd-hardware Tue Oct 7 23:46:05 1997 Return-Path: Received: (from root@localhost) by hub.freebsd.org (8.8.7/8.8.7) id XAA25424 for hardware-outgoing; Tue, 7 Oct 1997 23:46:05 -0700 (PDT) (envelope-from owner-freebsd-hardware) Received: from www2.shoppersnet.com (shoppersnet.com [204.156.152.112]) by hub.freebsd.org (8.8.7/8.8.7) with ESMTP id XAA25419 for ; Tue, 7 Oct 1997 23:46:01 -0700 (PDT) (envelope-from digital@www2.shoppersnet.com) Received: (from digital@localhost) by www2.shoppersnet.com (8.8.5/8.8.5) id XAA24559; Tue, 7 Oct 1997 23:43:57 -0700 (PDT) Date: Tue, 7 Oct 1997 23:43:57 -0700 (PDT) From: Howard Lew To: Greg Pavelcak cc: freebsd-hardware@FreeBSD.ORG Subject: Re: Finicky SDRAM In-Reply-To: Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hardware@FreeBSD.ORG X-Loop: FreeBSD.org Precedence: bulk On Tue, 7 Oct 1997, Greg Pavelcak wrote: > I'm sorry to post this here.

Does anyone have any experience with these > mobo/proc/memory combos? Any recommendations? I don't know much about M-tech motherboards, but when you ask for SDRAM you need to check a few things... What speed are they? There's 66MHz, 83MHz (12ns), and 100MHz (10ns). Faster of course is better. Then you need to check if your motherboard can handle 10ns because some will not. Next, there's the issue of using buffered vs. unbuffered sdram. And finally the 2 clock vs. 4 clock sdram issue. In short, check your manual or contact M-Tech for their recommended SDRAM type. The kind of SDRAM a system takes varies with motherboard manufacturers and chipsets. Is this the motherboard model that runs the PCI bus at 33 with the bus clock at 75? If not, then check your PCI cards because some cards (i.e. some generic S3 ViRGE) will not run higher than 33.

ROFLMAO I would like top thank you all for such a great response. This should prove to be an interesting project as it progresses. My apologies to anybody who might not find this 100% pertinent to this group. This is the company that we hope to a partial sponsorship from <> for our dashboard. But we are going to wait a while before we contact them. If all goes well on our end we should have carbon-fiber driveshafts and extrude-honed heads/manifolds, US Gear Under/Overdrives which takes you automatic or manual tranny and overdrives each gear. Meaning a three speed is now a six, and a six speed Viper tranny is now a 12 speed transmission. B&M makes a tranny fluid sensor. We are going to push for all of the "chasing the rainbow" technologies so that we have a better shot at a world record. The guy who broke it last didn't really do anything special to his block. So we have an edge there. There are a number of companies that make sensors for tailshaft measurements. So that shouldn't be a problem. VDO from what I remember makes a sensor for just about everything. Stewart Warner probably makes the others for racing that VDO forgot. Jacobs <> if I am not mistaken makes a crank trigger for Chrysler ignitions FINALLY, so we can sense off of that. If they don't, MSD <> probably does. Turbo Hi-Performance magazine has enough companies listed that picking up the other sensors shouldn't be a problem. Interesting point.....When G.M. was promoting their extensively and I mean extensively modified Cyclone pick-up several years ago out at Bonneville the engineers discovered something. As the pick-up got up around 200 mph they lost radio contact with their vehicle. The later figured out that at those speeds on the salt flats a static shield envelopes the vehicle. I hate when that happens :) They probably could have thrown a 75' piece of wire out the window and had it work fine though. Until I get all of the official information here, I believe I will be making a 125 mph pass to qualify the vehicle because it and myself have never been on the flats before, then a pass each way through "The Flying Mile". If the vehicle shows promise (150 mph +) I believe I can go on the 8 mile course. If we can make 140 I'll be satisfied, as I cannot make body modifications in this class and a 1973 Dodge is about as aerodynamic as...............well..........a 1973 Dodge =) Thanx for the info on the Bosche stuff, the next project race vehicle will be an A-21 Fuel (45% water, naphtha and the rest is gas) conversion on a 1987 Audi Quattro. But one scraped knuckle at a time.

Shh, don't tell anyone, but let me let you in on a little secret. The 'jitter' in GPS that makes most of the difference *isn't* random. Most of it is introduced, and that's what makes the accuracy < 100 M. If you remove the accuracy, you're down to ~1M accuracy, and by taking out the rest of the 'jitter', you can do better than .1M accuracy. However, for the above application, I suspect 1M accuracy is probably good enough. We call this 'fake' DGPS, and use it for many projects at SRI which don't need *really* accurate measurements. (SRI helped develop GPS, and continues to do alot of GPS research.) Again, I'm talking about removing the 'introduced' jitter, and not removing the jitter related to moving satellites/moving cars, but I don't think that kind of accuracy is *necessary*. Nate ps. However, I'm not sure how the 'static shield' talked about earlier would affect the GPS receiver. If it does, then GPS is a non-starter.

Uh, hang on a second. You want to use DGPS to remove the SA jitter, correct? SA jitter is by definition random, and DGPS uses the fact that the reference is known to be stationary to calculate the SA jitter. (If you're known to be stationary, any movement you detect must be bogus.) Once you have this data, you feed it in _real_time_ to your mobile; it removes the jitter and everything else must be "real" movement. You can't achieve this by "synchronising with the satellite clocks"; if you could predict the SA sequence from a given point it'd be worthless. Ergo you need a realtime link between the base and the mobile. A couple of Rockwell Jupiter modules (we pay ~AUD$300 each) and support parts will do this for you, or you could spring for a Garmin or similar handheld/console mount unit. These cost more but have pretty displays and lots of buttons. Less robust of course. mike From owner-freebsd-hardware Wed Oct 8 10:11:45 1997 Return-Path: Received: (from root@localhost) by hub.freebsd.org (8.8.7/8.8.7) id KAA01284 for hardware-outgoing; Wed, 8 Oct 1997 10:11:45 -0700 (PDT) (envelope-from owner-freebsd-hardware) Received: from word.smith.net.au (ppp20.portal.net.au [202.12.71.120]) by hub.freebsd.org (8.8.7/8.8.7) with ESMTP id KAA01277 for ; Wed, 8 Oct 1997 10:11:40 -0700 (PDT) (envelope-from mike@word.smith.net.au) Received: from word.smith.net.au (localhost [127.0.0.1]) by word.smith.net.au (8.8.7/8.8.5) with ESMTP id CAA00647; Thu, 9 Oct 1997 02:38:45 +0930 (CST) Message-Id: <199710081708.CAA00647@word.smith.net.au> X-Mailer: exmh version 2.0zeta 7/24/97 To: Chuck Robey cc: FreeBSD-hardware@FreeBSD.ORG Subject: Re: Very useful (fwd) In-reply-to: Your message of "Sun, 05 Oct 1997 19:56:08 -0400."

What's the point of it then? It's not predictable (well, it is, but it's a fairly complex algorithm that is not published, essentially making it unpredictable). The point is that the jitter introduced is the same across all of the recievers in the same general area, so if one of the receivers isn't moving, you can take the 'difference' of the changes made to it and apply it to the values on the other receivers taken at the same time. (In case anyone is concerned, my brother-in-law at the State of Montana is also doing this, so it's not like it's a state secret or anything. *grin*) Another rumor I've heard about is that the introduced jitter may go away. Interestingly enough, during the most recent 'war' (Desert Storm), there weren't enough GPS receivers that could read the 'encrypted' channel which has no introduced jitter, so they ended up turning off SA and using standard commercial receivers. It kind of defeats the purpose. That, and DGPS has made it virtually useless for anything 'sensitive', so there is serious consideration being made to kill it. But, many of the GPS manufacturers are fighting it, because it makes alot of their 'new generation' products useless, which rely on the introduced jitter. *sigh* Capitalism at it's worst.

You can also often use "real" DGPS by adding a DCI correction unit and subscribing to their correction service, though you are limited by their coverage ranges (they use commercial FM radio stations to broadcast the correction factors). SA is easy to remove, but it is not what ultimately determines accuracy - other considerations do, such as satellite azimuths, multipath distortion, atmoshperic distortions and so on. Post-measurement DGPS is less accurate the further apart the measurement GPS and base GPS are, since they will possibly be seeing a different constellation of satellites at least some of the time. One advantage of DCI correction is that it includes corrections for all of the visible satellites, not just the 4 that happen to be used for the current 3D position fix. In developing a GPS-based position-reporting mobile data gathering system using both "true" DGPS and base-station DGPS we took a fair amount of field measurements. For "live" data - one sample every 5 seconds in our case - by far the largest errors occur in fixed base station post correction when the constellation of satellites change - often introducing a sudden 10m apparent change in position for a few seconds as the new satellite factors cranked in and the position came back to within a meter or so of the "true" position. These interrim readings *are* marked as less accurate by the GPS receiver, but if you must have a stream of live measurements you may not be able to just wait the minute or so for the accuracy to return. For vehicle readings, placement of the GPS antenna can be important, especially if you are using other radio antennas for telemetry. All of our experience was using Trimble Navigation 6-channel OEM units, but the specs are fairly close to units from Rockwell. -Dave Babler From owner-freebsd-hardware Wed Oct 8 12:10:24 1997 Return-Path: Received: (from root@localhost) by hub.freebsd.org (8.8.7/8.8.7) id MAA08592 for hardware-outgoing; Wed, 8 Oct 1997 12:10:24 -0700 (PDT) (envelope-from owner-freebsd-hardware) Received: from word.smith.net.au (ppp20.portal.net.au [202.12.71.120]) by hub.freebsd.org (8.8.7/8.8.7) with ESMTP id MAA08584 for ; Wed, 8 Oct 1997 12:10:19 -0700 (PDT) (envelope-from mike@word.smith.net.au) Received: from word.smith.net.au (localhost [127.0.0.1]) by word.smith.net.au (8.8.7/8.8.5) with ESMTP id EAA01082; Thu, 9 Oct 1997 04:36:11 +0930 (CST) Message-Id: <199710081906.EAA01082@word.smith.net.au> X-Mailer: exmh version 2.0zeta 7/24/97 To: "Gary T.

It is quite expensive though. I've got 19 of these in service right now. No DOAs, and no failures at all. A lot or people have been recommended various SCSI drives, howerver, lately some details of performance issues and bugs regarding the number of simultaneous commands they can handle. See archives (maybe, this discussion was recent and I don't know how often the archive is updated). > Someone else recommended the Quantum Atlas II series; Fry's (local computer > supermarket) has a Quantum Atlas II 2.2Gbyte fast wide drive for $265.

Well, I wouldn't do that. root is where you want the reliability.

If you need to go external, buy internal drives and put them into your own case. Power is not much of an issue.

Heh, saying "there weren't enough capable GPS receivers" sort of understates the military situation. Talking to Bob, who was in Desert Storm, reveals that some 90% of all GPS units used in D.S. were civilian models, most of the troops having pooled their personal funds and gone out and bought their own units before being deployed to Saudi. Line troops have this little "hangup" about calling in accurate requests for artillery fire, you see, and there was so such demand for them that very few units actually got the military models they asked for, so they went to the civilian market on their own in droves, even when the hand-held models were selling for $3K or more. Bob's artillery unit even collected $3K in personal donations and went off to buy their own, only to be frustrated when it turned out that practically every available civilian unit on the market had been purchased already and finding one for sale was almost impossible.. ;) Jordan From owner-freebsd-hardware Wed Oct 8 19:47:34 1997 Return-Path: Received: (from root@localhost) by hub.freebsd.org (8.8.7/8.8.7) id TAA02444 for hardware-outgoing; Wed, 8 Oct 1997 19:47:34 -0700 (PDT) (envelope-from owner-freebsd-hardware) Received: from wong.rogerswave.ca (wong.rogerswave.ca [204.92.17.32]) by hub.freebsd.org (8.8.7/8.8.7) with ESMTP id TAA02306 for ; Wed, 8 Oct 1997 19:44:40 -0700 (PDT) (envelope-from wong@wong.rogerswave.ca) Received: (from wong@localhost) by wong.rogerswave.ca (8.8.7/8.7.3) id VAA00519; Wed, 8 Oct 1997 21:42:01 -0400 (EDT) Date: Wed, 8 Oct 1997 21:42:01 -0400 (EDT) From: Ken Wong X-Sender: wong@wong.rogerswave.ca Reply-To: wong@rogerswave.ca To: "Christopher R.

I have a Compaq Presario 4112 (P120/16M). It seems to lock up at various stages of installation. I'm using eide drives, the on-board video, sound, etc. I also have an AT&T chip modem card installed(which I couldn't seem to get recognized). I also installed it here at work, where everything's generic. It works great. Could the locking up problem be because of a proprietary motherboard? Also, I read in an earlier FAQ that FreeBSD has a problem with WinModems. How can I I.D. if that's what I have? Is it printed on most of them? When I look at the properties in W95, it doesn't mention Winmodem. Unfortunately, when Compaq makes a family PC, they want you to pay them to upgrade or do anything to it. I had a heck of a time adding a second hard drive. Anyway, when I was inside the PC to upgrade my space, I noticed only one identifying mark on the motherboard(other than "COMPAQ"). There was a graphic of the alien head in the movie Predator stamped in white near the memory banks. Does anyone know the origin? -- UNIX Rules!!!

Let me second the recommendation for the IBM 5400RPM DCAS 34330. Although it's only a 5400 RPM drive, it's relatively fast -- comparable to my old Quantum Atlas I's, which are 7200RPM drives. The IBM is also a *lot* quieter and a *lot* cooler. The 4GB version is also pretty inexpensive at $399 (http://www.basoncomputer.com), although this is for a bare drive *without* instructions (you can get the basic information off a sticker on the drive, or you can go to IBM's web site for detailed drive information). [ A couple of months back, I asked here for recommendations for quiet drives, and the IBM was what I got based upon the responses.

Cation is in order here, Bason Computer is a grey market drive dealer, they purchase excess OEM inventory and sell it to anyone who will buy it. They tend to stand behind it very well for the 1 year Bason warranty, but do not expect to be able to file warranty claims with the drive manufacturer. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation, Inc.

I'm not too worried, though (although others may be). Chances are, if the drive is going to die, it'll die in the first year (the IBM drives seem to have a pretty good reputation thus far ;-). If Bason is pretty good about their one-year warranty, that's probably good enough. Anyway, for future reference, does anyone have any recommendations for better drive vendors (ones that have the IBM DCAS drives in stock)? -- Darryl Okahata Internet: darrylo@sr.hp.com DISCLAIMER: this message is the author's personal opinion and does not constitute the support, opinion, or policy of Hewlett-Packard, or of the little green men that have been following him all day.

I've purchased a lot of drives from Bason, and they have always been very straight-forward and easy to work with. Occasionally, I've had to return stuff to them, and it hasn't been a problem. Of course, I try not to do that too often (I try to buy the right thing the first time :-). Yes, they are not going to hold your hand if you don't know which end is up. But if you know what you're doing, my experiences with them have all been positive. For what it's worth, I've also purchased several drives from MegaHaus in the past, when their prices used to be really good (lately their web prices have been on the high side). I really don't have any complaints with them, either, but they are basically in the same category as Bason. FWIW, I had to return a hard drive for repair to Quantum that was over a year old, but under what MegaHaus claimed was a two year warranty. MegaHaus said I had to handle it with Quantum, and the Quantum guy said that I had purchased an OEM drive that was only covered by a one year warranty, and that MegaHaus did this on a regular basis. Still, to Quantum's credit, they fixed it for free, anyway. If you want someone who will give you warm fuzzies, and take care of any complaint, no matter how minor, these may not be the best places, and you should be prepared to pay a little more. ----------------------------------------------------------------------------- Michael L.
