- Do they make kits for this? Kinda. What's the fun in buying things like this when you can spend tens of hours and hundreds of dollars just to save a few bucks. I'm not a professional engineer or a decent coder, and this is probably the wrong way to do something. But at least it's cool.
The files for this project can be found here, and I swear the code will be up in a few days. STL Files: www.thingivers...

This is so freaking cool. Only comment I have is to maybe adjust your thumbnails so they’re more easily recognizable as you and your projects. I skipped past your video in my subscriptions feed a few times not realizing it was you and the vette 🤘
Love seeing this level of detail in the building process, it's really missing from most of the other build series channels.
I like this series! My two favorite things: corvettes and v12s😂
Thanks!
@@WesleyKagan no problem Man! Keep up the good work!
This is an amazing integration of Arduino for your speedometer, tach and odometer! However a few things that might improve it would be to dump the servos for a number of reasons. First of all I don't trust those servos to last very long due to the constant usage and movement of driving. A far better option would be to use small stepper motors which would be the perfect aplication for this. Also using GPS for speed is going to have some delay as GPS calculates speed based on distance over time so they'll be some lag there, but it might be manageable.
As long as he doesn't use A4988 on them^^ Stepper motors can be quiet or loud just depending on the driver you use for them. A4988 can be loud and high pitched, when you run them from an Arduino (I heard faster 32bit processors could reduce that issue, but he will most likely want to keep the Arduino) The TMC2208 (or TMC2209) might be a bit overkill, but would be wonderful quiet, which you want on long car drives. The TMC2209 would be the best, since they have sensorless homing, so you could home the neadle against the post.
Your technical skills are really impressive. Look forward to each update on this project
when you say transistor, what you actually mean is linear voltage regulator. it should have a capacitor on the input side as well as the output side to give better voltage stability and a heatsink might not be a bad idea either.
Really cool seeing a car guy get into the electronics game.. The only thing is you keep calling the voltage regulator a transistor which it simply isn't😉 nothing to worry about though. If I were you I probably wouldn't use a voltage regulator but a DC/DC Stepdown module from eBay or something (since you are dealing with quite a bit of max current as you already said). If you want to stick to the regulators, keep in mind that adding a second one won't double the max current since they are very precise devices and not calibrated equally. One will have a slightly higher voltage and therefore supply most of the current. I've heard somewhere that the current distribution for adding two voltage regulators is somewhere as bad as 70/30. Either way it would be good practise to put a small heatsink onto the regulator! Love your vid!
Genuine genius. I love that you dont butcher the car with a digital dash as most would.
I really like your approach on these things!! Thanks for sharing it with us! Already looking forward to the next vid
I've had this same idea for quite some time, so it's awesome to see someone make it a reality. Now I need to search your channel to find any updates...
Great video. Sweet to see how these functions can just be mapped to meter movement, replacing one old electro magnetic solution with another that is programmable.
I have been attempting this for years with my C10 truck. Things I was missing are knowledge and understanding. I got so far as to use my Arduino mega to produce a 5V square wave signal that I had converted into a servo angle based on pulse frequency. It didn't work very well at all. I used the speed sensor from the newer manual transmission.
Wow man, as a custom car builder/12v enthusiast, im very impressed at your abilities. Ive never understood coding. This is definitely a cool project!
Cool idea, I would add a memory function if it was me too so that you could check to see the max achieved engine speed since reset, its a feature on a lot of aftermarket electronic tachos and it comes in handy (I used it on racing cars with gentleman drivers, it was always handy to see if they over revved the engine). But great execution fitting it into standard clocks.
I’m considering an external port to plug in a display, to replace the clock or something and then have a full data stream- oil temp, memory functions, shift lights, exc. I might mess around with it.
@@WesleyKagan Does the nano have built-in CAN bus support? That would make this quite a bit easier. I've used the Teensy before, which does have built-in CAN.
@@daviddbh97 Not quite, but you can buy a CAN-Bus board that interfaces with an Arduino
Love the project, just discovered it. I hope there is more excellent content coming soon. Good luck and keep us posted.
Hot Rodding has come a long way since my day. I find this all very fascinating. Carry on.
Awesome man! I love your work. I have an old mini that I want to incorporate a lot of these ideas into. My speedometer is already way off and I've always wanted to add shift LED lights that illuminate as the revs go higher and this seems like an easy function to add to this setup.
They do make a tach conversion kit that just replaces the mechanical mechanism to electric on 68-73 Vettes, but I have never seen the speedo conversion, that is very interesting. I would be concerned the the tach couldn't keep up but can see how the speedo probably could. I would be interested in the speedo kit if you get to selling them.
this is such an amazing project and so well executed and presented, thank you for sharing it all
Great project! Just FYI, A 7806 is not a transistor, it's a regulator. Very different!
Amazing build. Would love to see an overview of the MS3Pro installation- what components you use, sensors, wiring diagram, TunerStudio configuration for the V12 and any troubleshooting. Looking forward to the rest of the build!
I have the exact same problem to figure out some day. It's on my list but way down the list. Thanks this will be very helpful.
I also have an active suspension project I've taken a crack at twice. a G sensor and 4 steppers running the dampeners. some day I will get the code figured out. Great channel, love the level of tech.
Great content. Love how you can handle both the electronics and mechanicals.
Very cool! Plan on doing something potentially similar for a future MR2 engine swap. Really want to keep the original gauges working.
Having a gauge sweep for the power up sequence would be a nice modern touch
You say you're not an engineer or coder, but would love to what know your background is, as your skills are pretty impressive. Anyways, just wanted to say, loved the porsche based project and look forward to seeing you tackle the intake and engine as well as the body, but this is an interesting and original project (at least to me, I'm not a corvette guy!), and enjoying the variety of skills being brought to bear on this. Well done and definitely subscribed.
Such a cool project. I never considered building gauges like that but it's an awesome idea 👍🏻
definitely interesting, good vid!
Awesome project and 'hi' to my fellow Phoenician. The stock gages are classic and worth keeping. I've got a '77 project and have thought about this alot, nice to see someone is like minded. Would like to see if you were able to smooth out the code and the final results.
Love the technical stuff. Please sprinkle some more!
Saw this pop up on Hackaday. That's awesome.
My 1976 Chevy Blazer 4x4. Broke it's Speedometer Cable, back in the 90's. I never bothered to replace it. Because, I was running 35 inch Tires. So, it was very far off, on the speed it was showing. This Cool setup. Would make my Speedometer right. No matter what size of Tires I run. I have an Arduino UNO. And have been considering what project I would like to use it on. You're Corvette Gauges, look allot like mine, on the back. I wonder, if your design. Could be adapted to my Blazer... You do great work... Don
Oh man, wish you lived closer to me! I have a '73 and my wife has a '75 that would really benefit from this. Would love to do this with ALL the gauges so you could have a bit of filtering from the sensors themselves (can you imagine a gas gauge that's actually somewhat accurate!?)
This channel is awesome!
Very interesting videos. I have liked and subscribed. I just gotta see that Mercedes run. It is truly unbelievable how you are able to put each hurdle behind you and not in just this project.

A great video 👍 good tech info is appreciated on a build project it's not all about getting covered in oil etc.
Once in a while, do a Wesley styled ‘engineering explained’ type presentation would be sweet
This is pretty cool, but when I realized what servos you were using, I was thinking "That might be noisy." Have you considered stepper motors (similar to GM clusters -- like in the 2003+ trucks) You can buy kits with like 6 or 7 stepper motors for cheap. Just a thought. I found your channel the other day with the Koennisegg lawnmower engine and I've been hooked!
One problem with gps is that if you go up or down a hill the speed will be incorrect!
btw, amazing channel, I instantly subbed.
So awesome mate, thanks for this and everything else! Inspirational!
I'm going to do this to my motorcycle. Thanks 😁
Really like the technical videos :)
Great viewing, keep up the good work. Try and get some video of the stuff being printed
Awesome project, but I would definitely look for taking a pulse train from the transmission's speedo output to calculate your speed. If you're lucky there will already be a hall-effect sensor on it for the speed.
GPS is far too problematic to be used reliably for a speedo, especially on hills, in the city, and in tunnels.
I was thinking 2 weeks ago of doing the same conversion on an MGA where the tachometer no longer works correctly. Thanks for sharing, so it is possible.
Great video, very interesting. I also think the gears are too loud.
Good video man
Amazing! I'm following this for sure!
Wow - 👍👍😎👍👍. Very interested in all details.
I really like your design there! You mentioned you were running speed and I would assume the Odo off of GPS... What happens if it loses signal, ie; a decent sized tunnel??
If you went through a mile long tunnel and lost full connection the odometer would not count that mile i'm afraid.
Only way to counteract this would be to use the studs on the back of the wheel rotor as a "Poor mans" ABS/Speedo signal by attaching a bracket and a hall sensor
This is really amazing and incredible work! Very impressive. Some comments: There are small stepper motors specifically made for gauges; it's what modern cars use. Adafruit has one called "Automotive Gauge Stepper Motor". But servos seem cool too. Maybe using a herringbone gear would make less noise? The 7806 is a voltage regulator (I think you called it a transistor, which maybe it is, but it's only used for voltage regulation). Finally, I'm curious how you'll make the continuous rotation servo accurate for the odometer. Do you have a positional feedback measurement for it? This is a case where a stepper might make more sense because it's continuous but controlled (unlike continuous rotation servo). Keep up the awesome work and have fun!
Nice work!
Love your videos!!
Very cool, the Java I've been teaching myself to make dumb bank programs hasn't been made in vain. Yes that's C++, but I understand it.
I'm far from a C++ expert myself. I prefer Java, personally.
Love it
What happened to this project? Did it ever get finished? I really want to see the finished project. It's so cool!
I thought factory cars used stepper motors. Very cool!
So Cool...
The 7806 is not a transistor, but a integrated linear voltage regulator.
Out of curiosity, why not steppers?
I like this. I'm building a '68 RoadRunner and a '84 Mustang SVO. I was looking a few days ago at how I can run the speedometer from GPS for the RoadRunner because I've got a 518A trans for the car and I'm left without a cable drive. the sweep on my speedo would not be 320 degrees you have but that could be worked out in code. That leaves me to ask about your 3D printer and your plasma table. Did you build these, are they store bought, maybe built from kits? You seem to be pretty adapt at making things and that's why I asked. If you built them maybe vids on those would be cool things. Great stuff, good job. DC
He's got a Prusa 3D printer it looks like, a very nice piece but you can do good work on something cheaper. I'd love to see what he's done for a plasma table! I've seen some small "home" units but they're still a few grand.
What would we like to see you build? Funny, but a sex doll robot. With your attention to details, it'd probably blow minds.
Cool project! We would love to see you publish a write-up about the project over on Electromaker.io!
Can't find the code on your site or in the description. I'd like to do something similar, but could use the example because I'm bad at arduino.
I've got a 57 Chevy that I'm planning on putting a T5 in, It will likely not have a mechanical speedo drive. This like a good approach over those expensive converter boxes. I just need the speedo and odometer. Speedo seems straight forward to control, odometer seems a bit more complex. Any suggestions would be appreciated.
Nice project. Can U share code for arduino?
What formal education do you have? What do you do for work?
It’s cool that you’re retaining the factory gauges, but what’s the response time going to be in correlation to indicated RPM to actual RPM?
Wholly fuck how old are you? Very smart young man. Need a step by step video on your wiring the squirt to the merc engine.
Awesome
Standard screws? Do the what now? What standard? SAE, DIN, AS/NZS, Whitworth, Metric, Imperial or American Wire Gauge?
Cool project. I'm also modifying my speedometer from mechanical to electronic except mine is a strip speedometer so it's a little more involved.
What do you think about the noise level of the servo motors? Personally i'm trying to make mine as quiet as possible and to me it feels like these are quite noisy.
I'm curious why you didn't try using something to make them move smoother than just 3d printed part on 3d printed part
Dishonored 1 >>> Dishonored 2
I did some experiments along this line for my 55 Chevy PU. I found an unacceptable amount of backlash in the gear drive. For example, the speedo would read about 3 MPH different if it increased from 40 to 50 versus decreasing from 60 to 50. I was using a Tower SG90 servo. What's your experience like?
LM7806 is an integrated circuit. Not a transistor. Just saying.
how do you count the frequency of the square wave in arduino code?
You can use external pin interrupts that will tell the cpu when a specific pin state changed between high or low. You can then make the CPU call a few lines of code within an ISR routine (every time the pin state changes) to determine the frequency by counting the amount of interrupts over a specific period of time.
any chance to post code for this project? i have a similar application for older Toyota truck
Is there a way to make the movement of the needles smoother and less juddery?
Nicer servos would probably help, the stuttering is the internal gears of the servo. Also the gears he printed need to be cleaned up like he said but mainly the servos
Also cleanup of the signal information would help too
Any updates?
I've never seen anyone actually writing their own code for a car build before. Are you self taught or a college graduate ?
code?
What if your gps reports over 160 mph?
wesley what happened? It's January 2022.
thank you for using the original gauges. Nothing looks dumber than a dashboard full of ugly aftermarket shit and blue LEDs on a 70's car. These look great. A million times cooler than throwing money at some company that makes purpose-built ugly shit.
