Actually, that sounds neat. I'll get on it with an ESP32 or ESP8266 and see if I can do something like that. I mean, why bother formatting it in OBDII other than wanting to see the values via a known device? It'd be easier to just have a simple web page hosted by a microcontroller that taps into the sensors and then reads the values and presents them on a Webpage for you to connect to. https://diyprojects.io/esp8266-web-server-part-5-add-google-charts-gauges-and-charts/ CommieGIR fucked around with this message at 17:48 on Jan 9, 2018 |

I replaced the alternator in the Avalon today. Straight 95/5 job, where 95% of the job was done in 5% of the time. The screw tensioner was absolutely frozen in the adjusting block and the only way to get everything out and apart was to bust the head off the nut. Thankfully, I was able to mount the block up in the vice and pb blaster/heat it up until I could get the threaded part of the bolt out. New stainless bolt from Home Depot and running it in and out of the block a bit to get the threads unfucked and it went back together fine. It's always the littlest, most stupid thing. But it's together now. We'll see if that takes care of some of the lovely starting issues I've been having with a battery (new last year) that slowly loses charge.

OBDII doesn't necessarily mean CANBUS - he's basically asking to build a pseudo-ECU that instead of actually controlling the engine, just reads sensors and can speak an OBDII protocol out to a scantool so that a dedicated interface doesn't need to be developed. Of course, CommieGIR is probably right that it'd be easier to build some sort of web interface with the features needed, than it would be to implement OBDII to use a scantool. At a very high level, this is similar to how a lot of newer Jeeps, when engine-swapped, still retain the original ECU just to read sensors. It doesn't have any control over the engine, but it does translate sensor readings into PCI bus commands that the gauge cluster understands.

I'll work on something this evening, we might be able to piggyback through simple connectors or taps. Either way, we could make it adjustable too where you can set 'limits' and initial values for the sensors to make it multi-car adaptable. The goal, of course, would be to minimize needed wiring.

Hello, fellow power industry person.Adiabatic posted:
Batteries - the industry is keenly aware that the moment batteries can store gobs of juice then it's just run hard to charge, maintain at base load, and then probably watch your margins narrow even more. Try to find information on supercritical fluids used to run super dense power generators: small footprint spinning at 60k-300k rpm. Its still all in research as far as I know but pretty cool stuff.

I'd like something like that, because I want a configurable display, like Shadow Dash (Android) for Megasquirt or Autometer's dash (loving expensive.) I want to do custom LCD dashes that I can create and interface for that gives me the info I want, or just looks cool, at the touch of a button, kind of like the GTR's configurable display, but for the whole dash. I want to make it look like a Lexus LFA if I want. Actually, something a lot like the Hellcat's various modes would be what I'm shooting for. Autometer's dash is pretty cool, but it's $2500. I don't get why there isn't a box with a USB cable and a bunch of sensor inputs that can hook to a laptop/carPC or Android tablet, and an app that can read from it. It would seem like an obvious product, and I'd buy it for, say, the cost of a suite of Autometer analog guages. Like $200-350? Am I way undervaluing that sort of thing? Make it cost a bit more if you want datalogging or something. I'm no kind of programmer or hardware designer, so I don't really have an accurate insight into what it would take. I'd even love a kit of some sort. I can build electronics (I've built two functioning Megasquirts so far.) I've seen some of the utility as far as dashes in DashCommand and OBD Fusion, but of course, they're dependent on OBD II, and sometimes car-specific unlocks for PIDs. ShadowDash is neat, but it's dependent on MegaSquirt for the data stream. It gets speed data from GPS, but adding something like oil pressure that's not tracked by the MS is problematic. I look at this off and on. As a custom, non OBD II solution, Arduino can get you a lot of the way there, if not all the way, or even a Raspberry Pi, I think. IOwnCalculus posted:OBDII doesn't necessarily mean CANBUS - he's basically asking to build a pseudo-ECU that instead of actually controlling the engine, just reads sensors and can speak an OBDII protocol out to a scantool so that a dedicated interface doesn't need to be developed. Of course, CommieGIR is probably right that it'd be easier to build some sort of web interface with the features needed, than it would be to implement OBDII to use a scantool. You know, given the ubiquitous and thoroughly hacked nature of the '90s GM ECUs, that might be the way to go. I've been considering something similar just to drive the tach on the '88 Cutlass Supreme digital dash that depends on the ALDL data for that. All the other gauges work off of normal GM sensors, but not the damned tach, despite the analog version just using the tach-out from the ignition. I'd really like to stuff that vacuum fluorescent display in my '70 Cutlass. There's a nice symmetry there. New/old Olds. Larrymer posted:Understandable. What do you want this info/functionality for, exactly? To look values occasionally on Torque? Does Torque let you log and save data (never used it, so still trying to understand)? If that's the case, that's the only advantage to doing this that I could think of. Otherwise just throw gauges in the glove box. Speaking for myself, I want configurable gauges, and gauges that I can change the look of. There's also an aspect of you can cram more info on an LCD panel than trying to fit a pile of round 2" - 2-1/2" gauges in a given spot. With something set up like OBD Fusion, you can configure several dashes with different info and swipe between them as needed. Extending that, you can have stuff come to the forefront if it hits a limit (DANGER TO MANIFOLD!) Basic speed/tach/fuel/temp/oil pressure for daily driving, deeper stuff like oil temp, trans temp, etc. fro special needs, towing, racing, whatever. quote:I understand that, I'm just saying you're not going to be able to get away with sending this via a few wires like modern cars can with bits and bytes vs. just a voltage that's then translated via a lookup table or whatever.

I know you young kids find it hard to believe, but this is literally how it was done before CANBUS. Lots of wires. Adding an ECU to the mix would add a few wires, but all of them would be run to the ECU rather than the dash, basically.

The current average WHOLESALE price of power in AU at the moment is $87.40 per MWh. http://reneweconomy.com.au/nem-watch/ Unfortunately whilst we're one of the biggest producers of uranium in the world, we've got one single 20MW open pool light water research and medical reactor at Lucas Heights in Sydney and thats it. We dont have any real knowledge or expertise base in nuclear power generation so everything would have to be imported from another country. Most predictions recon that even if we started today, we wouldnt be generating power from nuclear for at least 25 years. Theres also an irrational fear of nuclear here in Aus, so NIMBY comes into play BIG time when your looking for somewhere to put the thing- Hell, we're the most geologically stable continent on earth and we still cant get public support for a nuclear waste depository in the middle of the loving desert! Transmission distance also cripples us too- if you were building a nuclear plant, you'd want it to serve as much of the country as possible but the distances are insane for power transmission- eg Adelaide to: Melbourne - 727km Sydney - 1375km Brisbane - 2000km Perth - 2693km Darwin - 3000km Its makes it really difficult to transmit mass amounts of power around the place. Add to that the whooooooole lotta nothing in the middle  And its a big problem

Right, not going to quote an entire wall of everyone's posts regarding the gauges thing, but I can summarise it as what I want is to have a way of displaying gauges easily on, say, a phone, or Android-based head unit. The desire is to be able to get into a car without that kind of plug-and-play functionality - whether just slightly before OBD2 became a thing, or something 50+ years old - and have access to stuff like temperatures and pressures beyond what is displayed on the (orften relatively basic) dash setup, but without anything standing out other than "that looks like a modern head unit in a 1990s car" levels of subtlety. I don't mind if the hardware on the car would be permanent or semi-permanent in its installation, or needs specific setting up/calibrating on fitment, but I don't want stuff on show, and I absolutely don't want to cut the dash and fit extra gauges etc. No, it wouldn't need to be OBD2 for any particular reason, I just thought of that as there's already lots of options to plug into an OBD2 port with a bluetooth or wi-fi dongle and let you configure virtual gauges for the data, and these apps etc are already fairly polished looking and user friendly to mess about with, it'd make it nice and universal - so regardless of what loving about you need to do behind the scenes, it looks/works the same getting in an "actual" OBD2 car with a dongle plugged into it as an older car fitted with this. Data logging isn't really necessary, though again, if you make it work with the existing apps for this stuff, you can do this kind of poo poo on some of them anyway. I'm kind of thinking that you can get a basic temperature/pressure sender like for a normal electrical gauge, and "all" you need is to take the output of that, correlate what that means in terms of the measurement, and kick out (whether to an actual OBD socket, or just skip straight to the wireless signal a dongle would give when plugged into the socket) whatever it is that the OBD2 on a modern car would say. So the app on your phone sees the same thing it would if you were using it "normally", in that sense. I agree that you could make an entire standalone system with either its own small screen, a video output, or something you view in a web browser etc, I just kind of like the idea of it working with all the OBD2 apps etc that already exist, and someone else has put a chunk of effort into looking/working nice for you. Also, I'd like it if it's something you could knock up on a DIY basis for, say, $50-100 plus whatever sensors you're using. I imagine something like a Raspberry Pi would indeed be a good way to go, but it's not something I know anythign about. Tomarse posted:Sorry guys, I didn't mean to start an argument.
