The Door Frame posted:Would you release open source software for an automobile made for the average consumer? The legal liability would be obnoxious I think most of us are thinking about just a graphic/interface layer that shouldn't touch the actual operational guts of the thing. Godholio posted:There's an entire tuner industry built on overwriting/supplementing that software. Replacing gauges seems trivial in comparison. You'd think, but the only systems I've seen that can do it are stupid expensive (Autometer, for example), either because they have a bunch of other features like datalogging, or they're made by Autometer, or very limited. Some DIY stuff is out there, which may be the way it has to go. I've been hoping for a reasonably priced commercial unit with an open API for the dashboard graphics and layout, so user-created dashes can be easily done without disturbing the underlying code, but that hasn't happened yet. Basically, WinAmp for a car dash is exactly what I'm envisioning. A nice, little LCD panel or two, a controller, and some software for uploading dashes and configurations to the controller. The very few I've seen so far that even approach this ideal require ODB2, which does me no good at all, as I want these things so I can have modern instrumentation in my old junk without having a million discrete gauges. And I want it to look freaking cool, like the LFA or recent Lambos. In my scenario, standard gauge senders, perhaps even calibratable for different senders, OEM and aftermarket, would be used. GPS for speed. RPM might be trickier, but aftermarket tachos seem to bring it off. Bonus points for being able to load and switch between multiple layouts ala the Nissan GTR's multifunction display or a number of supercars. I don't have near the hardware or programming chops to bring it off, unfortunately. The best solution I've seen so far is the Shadow Dash, running on Android tablets, for the MegaSquirt. It has most of the functions I want. I think you can implement sensors that the MegaSquirt does not immediately support (like fuel level - that's a big one) via dataloggin provisions, but I'm not certain. Biggest drawback is that you have to have a MegaSquirt, which could be an issue if you already have an EFI system you like, or want to stick with carburetion. Dash Command does some neat stuff on phones and tablets, but it's one of the ones that requires OBD2.

I wonder if there is some kind of deeply buried regulation or SAE code somewhere that states minimum font size from certain distances for certain gauges (whether digital or analog), legibility in whatever conditions, relative gauge size, etc. which makes the relatively simple act of skinning a digital dash actually a big enough pain that all an OEM can really let you do is change a few presets and colours, in which case what's the point. And the alternative is hacking together a completely home built solution or paying a lot for some 3rd party to have done some amount of research to ensure their product is compliant in the markets they sell it in.

I'm using an ultra widescreen 12.3 inch 8:3 aspect ratio screen that was used in a.... Lexus?

Edit- like we're all thinking about wouldn't it be cool to emulate a classic gauge cluster or other conventional or slightly avant-garde retro gauge concept, but someone on reddit is probably already thinking about how to skin their dash so that speed is displayed in variations of rage face.

there were apparently HUDs on several old Toyotas and Nissans back in the 80s which was pretty surprising the first time i saw one e: also when it comes to cars i generally expect doing anything cool to them can easily approach $1000 very quickly if you don't DIY and/or want it to look good. but yeah that doesn't mean i'm gonna drop a grand on every little thing that i do to my ride especially when i can more often than not just frankenstein those same parts together for a fraction of the price if i can find it used while learning a bunch of trivial stuff along the way Thief fucked around with this message at 16:59 on Apr 12, 2018 |

Thief posted:there were apparently HUDs on several old Toyotas and Nissans back in the 80s which was pretty surprising the first time i saw one I’ve been doing the dashboard and data logging stuff for our lemons car, and it’s been really fun. It has no ODBII, so this is taking in the actual sensor data. It doesn’t display to a digital display, but lights up LEDs. This has not been cheap, even doing everything myself. I’m using a Raspberry Pi for data logging, but not the display, since I can’t seem to get the boot time as low as people claim. This project has bled into another project, where I’m engine swapping / megasquirting an old truck. I want to keep the original gauges, so I’ll make a board to take in the MS data and analog data (VSS, fuel, etc), and then drive the analog gauges. All this (and reading this thread) has me wondering if there’s a market for half DIY / half pre-made solutions. Of course the problem is that I’m not sure the price could be a huge amount less than the $1k. I’m also not sure how I would deal with the endless variety of sensors and gauges and everything else. It’s a pipe dream I’m guessing, but a fun one to ponder nonetheless.

Yeah, it seems $1000 is entry level for any commercial product. I'm still looking around at DIY projects, but for a commercial unit, I like this one: https://www.pegasusautoracing.com/productselection.asp?Product=MC-237 You can buy it with either a CAN-bus cable, an OBD II cable, or just an RPM input, then add a $99 analog input harness. The AEM CD-7 is CAN-bus only, $1300 to start (no data logging), and requires a $350 module to interface with analog stuff. It does some amazing stuff, though, including being literally infinitely customizable, since you can upload your own images for warnings and icons, for example. The Holley is pretty decent for right at $1000. edit: shoncook posted:I’ve been doing the dashboard and data logging stuff for our lemons car, and it’s been really fun.

That sounds like a couple of cool projects, though personally I'd just have parallel sensors for the gauges, which is what a lot of earlier EFI cars did anyway, particularly GM. Analog sender for the gauge, digital sender (or even just a different analog sender) for the ECU. Darchangel fucked around with this message at 17:49 on Apr 12, 2018 |

RE dashboard talk: GUYS, I absolutely LOVE anything dashboard related especially when it comes to old school digital dashboards. I humbly submit my RaspberryPi creation for a friend's crazy EV conversion project. (The Teslonda) It went into a 81 Honda Accord so I wanted a period correct aesthetic. My inspiration was a cross between 80's arcade game and early 80s digital dash (specially the 1983 mitsubishi cordia). here is a screenshot of it in testing mode (dont mind the numbers here: they dont make sense)  Here it is in action: https://www.youtube.com/watch?v=Uproz8DwcRE https://www.youtube.com/watch?v=Fr7YF1gJPks When the "motor" is cut; the dash goes into a "Continue screen" which counts down from 10, then it goes into a "demo" mode. The thing also serves up an app via wifi so you can do logging, etc on your phone. Raspberry Pi stuff is a goddamned blast! I plan on doing this with my personal project car (the 72 LTD with the big loud engine and hood scoop/shaker). Different aesthetic of course but the sky is the limit.

My main question with the raspberry solutions is usability. How long do you have to wait for it to present a usable dash when you turn the car on? And how do you prevent it from chewing up its SD card when power is suddenly cut? Guess I could just ask in the raspberry thread but this is where the conversation is.

I was excited about AEM's dash when it came out, but it's kind of pricey for what you get. The logging version costs the same amount as the non-logging version plus an aq-1 standalone logger, and the aq-1 is faster, has more memory, and more channels. With either the cd-7, 7l, or aq-1 you can add an odb-adapter to take info straight from the vehicle. And then if you use AEM x-series gauges, they will transmit over the can system so they do not take up any of the individual inputs (there aren't very many). Racepak/haltech's IQ3 logger dash seems to be a better value, as it includes the GPS antenna, has built in accelerometers, and logs to an SD card. I think they have an ODB module you can buy, and you can also just buy pressure/temp sensors and plug them right in. With aem you have to either buy a whole gauge or add the wires to the harness connector and set the calibrations yourself. Downside is you need to use their specific sensors for that to work. Both of those come up short if you want to log a whole bunch of stuff but they seem to be about the best priced commercial, ready to go options. The iq3sl is still like $1400 though. Meanwhile, you can do a whole lot with a tablet, and odb adapter, and the torque app. A way to take external sensors and that would be about all you need.

I'll post more details about the dash in the raspberry pi thread; but in short I'm just stuffing everything into it; GPS, logging, phone app connectivity, etc. ALL THE THINGS type of thing. It was also a chance to flex my dumb lizard brain design muscles. It was a blast and honestly honored people like it too. My 72 LTD is a ratty muscle car project that I also want to do all the things too. Mostly because it is my fun toy but it is also an excuse to learn new things. Here are some shots of her;    1972 Ford LTD Brougham. 2-door hardtop (vinyl long gone, someone before me replaced it with rhino lining lol). I rebuilt the engine myself from a 429 to a 466. New exhaust, headers, etc etc. Limited slip in the back now as well. I want to start making the inside nice again along with modern tech like cameras, etc. Hench the dash project! Though for the dash on that, I want to match the aesthetic as well and a longer screen. Should be neat. edit: (sorry didnt mean to hiject this with personal ride bs!)

I submit my vaporwave instrument cluster for my '88 Hawk GT:    https://my.mixtape.moe/gnkbsp.mp4 This is still version 1.0 (there have been some changes to the graphics and stuff since I shot that video). It does work, and I've been riding with it for a few months now with only like two glitches the whole time, but it's not feature-complete and I've discovered a bunch of things I need to change. Pretty fun project though and I adore the look of it at night. OLED is gorgeous. Unfortunately it's not readable enough in full sun, so I'm examining a couple of different monochrome RGB TFTs to split the difference. re. using these things on old cars -- the most advanced electronic device on the bike (other than the instruments now, natch) is the silicon rectifier. The instruments read the wheel speed through a 3D-printed adapter that takes the existing speedometer drive cable and revolves a magnet in front of a hall effect sensor. RPM comes from extensively filtering and measuring the ignition coil pulses from the front cylinder. Engine temperature uses the existing thermostat and the signal is so hilariously noisy that I think I do something like 200 samples for each data point before putting it into a moving window average. The main processor is a miniature Arduino-compatible ARM board with enough power to handle all the math, drive the screen at ~20fps, and drive the tach LEDs at like 100hz with zero lag which is loving awesome because I loathe laggy displays more than almost anything else.
