Finally, I was waiting for this video! Thanks man, keep up the good work! Ordering all parts asap!:)

[@amstudioprojects]

Enjoy the build!

[@RobinBalentina]

When you go max rpm when in neutral, does the needle bounces? Or doesn't it do it because of little input lag?

[@iszlaimatyasjeno1301]

If you use an Attiny 85 microcontroller instead of a whole arduino nano board...the attiny is 1 dollar the resitors diodes and transistors are cheap as hack and can be found in old electronics as well...so about 2 max 3 dollars for the electronics and the price of the rpm indicator which I have no idea how much does it cost... :))

[@KimNabi_cat]

i have faith in amstudio that he will come up with something

[@taohawaii]

No it isn't. The Arduino uses the "Tone" library to drive the transistor. The tone library is capable of outputting from 31Hz to 65,635 Hz. As seen in the video, it drives the tachometer over the full RPM range without breaking a sweat. If you pause at 4:49 you can see the software is configured to send serial data at 64Hz. So you will only get updates 64 times each second (making the needle "step" a little). The minimum number of cylinders the tachometer can be configured to accept is 4. On a four stroke, there are two up-down cycles (revolutions) between spark events. Since there are four cylinders, half of them have a spark event per revolution. Of those two, they fire alternating so each, single 360° revolution will produce 2 spark signals to the tachometer. (Unless it is a stupid (GM) and they spark even on the exhaust stroke...) The gauge reads up to 11,000 RPM so that is 22,000 pulses per minute for a 4 cylinder. Well under the maximum 65,535/s * 60 seconds in a minute = 3,932,100 that the Arduino is programmed to output. Since the minimum frequency is 31Hz ( * (60 sec in minute)/(2 pulses per revolution) ) the arduino cannot drive the tach between 930 RPM and 0 RPM. If you set the gauge for a 6 cylinder the gap would shrink to 620 RPM, and would be only 465 RPM for an 8 cylinder. This would require you to change the pulses per RPM generated by the Arduino however something simple like replacing "rpmTone.play(freq);" with "rpmTone.play(freq*1.5);" or "rpmTone.play(freq*2);" on line 994 of the sketch. You can see a general delay in the physical gauge lagging behind the virtual one. This is partially due to the 64Hz data rate but mostly due to the stepper motor in the gauge. The motor driver in the gauge has a maximum speed which limits the needle's ability to keep up. I think digital is best/fastest. If you need a needle, you can simulate one but you can get the same (better) effect with LEDs around the circumference. If you just want to be old school you can get great results with aircore gauges and driving the sin/cos coils with analogWrite()'s.

[@estufilla]

It's funny, because if you listen carefully to the sound, and watch one tach and the other, the Arduino one is even more synchronized than the one in-game with the sound.

[@user-cs4el3dm2u]

this guy is a DIY racing sim accesorie GOD

[@Gallardo6669]

Pretty cool. Needed only schematics, will use spare rpm gauge for wattage consumption on my home stereo system....

[@Bu0f]

Can I use a different Arduino board?

[@jsow99]

I'm probably gonna make it just so I can have it, unfortunately it won't be very useful in F1 and seems like it has quite a bit of lag and the needle can only move at a certain maximum speed. Other than that seems like a perfect addition for a sim rig :) I hope you make more of these 'inexpensive (relatively) but useful' things.

Hello, i am not familiar whih these DIY projects. Therefore, i do not understand why is the diode used to connect the emitter and the collector here. I wonder wouldnt the circuit works just fine without the diode here? Thanks

Can you do a boost gauge

[@MrEpicDude69]

The Bandinator this is what ive been waiting on

[@ProjectR86]

Another vote for a boost gauge tutorial. A fuel gauge would be good too because I'm thinking of building a instrument cluster and I'm not sure how pressure based gauges would work.

[@BboxBoy24]

Project.R Boost gauges work by pulling vacuum by tapping the vacuum line inline with the manifold pressure, to simulate would be pretty tricky. However digital guages might work the same as this tutorial.

Yea, that's what I was thinking with digital gauges. I'm not in a real rush to make one. I'm still waiting on the parts to make this Tacho and the other digital dash display that amstudio made made on KZbin.

Hi, can I use the same design to use a speedometer on simhub? works the same way? if it does not work, could you explain or make a video showing how to use a speedometer on simhub? if there are any typos please forgive me, because I'm Brazilian and I do not speak English very well

[@hotfuzz1913]

nice work cool tutorial

[@yozzychannel9611]

really nice and clear but the music Is too loud and disturb a bit

[@TheValKBawz]

Did you use the free version of SimHub or is the Tachometer itself too slow? It didn't seem to keep up with the input fast enough.

[@dangelosculture]

Hi I did everything as described once inserted in the sim hub loaded the scretch nothing the tachometer turns on but the test does not go in your video you do not see I have joined all three gnd. I don't understand what I'm wrong. Is it possible that it is the different diode? they sold me Diode 1n400

[@bonrullaren4721]

Hey, regarding the analog hanbrake video. Going to do that build in a few days when I get my handbrake. Quick question though, what is the biggest problem with having a bigger potentiometer (60mm for example)? It seems like it could fit, would it be problems with the programming and calibration or is it just not going to physically fit? I guess that you actually wouldn't have to use the whole length of the potentiometer if it is longer, is it so? Figured that I would comment on this video aswell so that you hopefully will read it. Thanks for the great informative and inspiring content!

[@amstudioprojects]

60mm should just fit and work. Travel of the handbrake internals is relatively short depending on spring, bracket and bolt combination you use. I recommend 35-45mm its easier to position inside the handbrake with adequate range.

[@bonrullaren4721]

amstudio Ok big thanks for the answer!

What amp rating should the 12v Power Supply be ? don't really want to be blowing my new creation up, I'm a massive fan of this channel with your quality DIY builds & I still have to get round to building that wicked hydro handbrake you did a while back, thanks for the awesome vid's....

[@amstudioprojects]

I am using a 12v 1500mA from a old external HDD

[@CaptainScarlet1961]

Thanks :-)

[@CaptainScarlet1961]

Hi, I'm having problems with this project, can you help ? For the record, in the interests of success I sourced & acquired the exact parts list that was in the video information including the exact same model of tachometer. I'm running 64bit Win7 Ultimate & installed SimHub as Administrator & it's the same version as in the video, I know there are newer versions but I kept to the video version to avoid any potential problems & I also have NO experience with Arduino Nano's so have no idea if the constantly flashing red LED is normal or if it signifies a problem of some sort as I have no information to refer to & the board is a Nano CH340G. The build went fine so I downloaded SimHub 5.2.0 & installed as Admin, I then plugged the Arduino into the USB & plugged the power supply in. I opened SimHub & selected "Arduino display/Hardware settings/Open Arduino setup tool" & got this message "Arduino is not installed or up to date, do you want to download it now" & as it was obviously needed I disconnected the USB lead & clicked yes to install which completed successfully. So I open the "Arduino setup tool" again & make the changes that you show, I put the com port & arduino board details in & then click "Upload to arduino" & after 3 or 4 seconds a small box appears saying "Compilation failed" & does it everytime I try. I've checked & re-checked & I can't see what the problem is, I've checked in "Device Manager/Ports" & it's listed as "USB-SERIAL CH340 (com3)" & is working properly so I know I selected the correct port & board in SimHub! I also checked in "Control Panel/Programs & Features where I found SimHub listed but nothing for the Arduino which strikes me as odd considering it has a program to run it or am I wrong ? PS: Sorry it's long.......

[@amstudioprojects]

Hey SmokinJoe! The flashing Led is the standard blink test to show the Arduino is working. Try update the Libraries. Also copy all the Libraries folders From :\Program Files (x86)>SimHub>_Addons>Arduino>Libraries To :\Program Files (x86)>SimHub>_Addons>Arduino>ArduinoIDE>arduino-1.6.13> libraries.

[@CaptainScarlet1961]

Thanks so much for the quick reply, I will try your suggestions shortly. I've since found out that there are "Cloned" Arduino Nano's from China flooding ebay with the same part numbers as the one I have, some of them work & some don't & another more bizarre thing was using the right kind of cable. I read a post on a thread that a fella was having the same trouble as me, turns out he was using a cable that was only meant to charge a device so borrowed a cable from a friend & bingo everything miraculously worked, seems a little far-fetched to me but could be so I guess. Thanks so much for your assistance, onward I go :D

[@amstudioprojects]

Thanks!!

[@danielthomas1986]

Love the videos great work. Can you run multiple gauges off of one Arduinos or does there need to be one each?

[@Dutch3DMaster]

You probably have an answer by now, but in case someone else wonders about the same thing: any pin with PWM output is capable of driving a single gauge (and then there's some trickery capable of being done with switching non-PWM ports on-off really fast, but that's definitely something that brings you down to the root of Arduino core programming).

[@spiderfightclub]

Heya thanks for the video, I just made one based on your instructions but after a while the tachometer desyncs and the needle goes below 0 rpm, do you have any ideas where I might be going wrong?

[@frogicus]

Great work man ! ...so I went and bought everything and put together...tach lights up and does initial test sweep but when i try it in program no go...do i have to donate? I noticed in your video that your device fps was 64...mine is 9... any ideas ? I set up everything exactly as you did including base orientation of the diode.

[@RomanFusaty]

good job my friend. I tried to make it by myself and bought the same tacho, however in SimHub is somehow not possible to make it work for the full 11k rev scale. When I press "Test max RPM" in SimHub, the tacho shows only about 7,5k RPM, not sure what can be wrong. Any ideas?

[@amstudioprojects]

Check the Tachometer cylinders match on SIMHUB and on the actual Tacho. Eg set both to 4

[@RomanFusaty]

omg it works now, You were right, there was wrong cylinder value set in tacho. Even though in manual is writen that default setting is 4, it wasn't. Thank You very much for advice :-)
