HI, i have and old speedometer broken, it used for motorcycle year 93, when i moved speedcup from cable attached, pointer or spindle is stand still, so what's possibility broken? thanks
thank u for da video. 1 doubt- most of da Indian 2 wheel vehicles speedometer is linked with the front wheel and der is no links present from transmission to magnet. so how does dat works??? or dis kind of speedometer only applicable to 4 wheelers??
Hello I'm wondering if it would be possible to rotate the blue speed cup (and therefore also the spindle) by electromagnetic field coming from the external voltage NOT from mechanical spins of the permanent magnet (connected with the cable). What do you think? I'm thinking about controlling such a classical speedometer from Arduino (or another microcontroller). It would be much easier to generate specific voltage instead of controlling the magnet rotation
The magnetic field has to be rotating, as it has to provide a rotational force on the cup. which is not easy to do as a DIY job. Maybe there are analog speedometers with electric input. My dad once made a fuel usage indicator from a tachometer from an old Ford Sierra (don’t know the year). That was completely electronic but with analog needle. I don’t know the further details on that project. Another option would be to control a motor with your Arduino and connect that to the input of the speedometer.
I have been following your videos for quite a while. It has great and easy teaching style which can be understood by everybody. I would like you to work on vidios which can teach how to make simple and working machine models for children with junk available in scarp markets, for eg. Making a wheel rotate in fixed axile at home, to Make a blower etc..
@@unknwn_usr3077 yes, but for that you would need to have information about the car’s kinematics (acceleration and time elapsed) to find it’s instantaneous velocity, and I believe you can’t have that on the fly.
It will change the speed that is showed in speedometer resulting in mistake. Smaller wheels will make the speedometer display a higher than real speed, and vice-versa. Hodometer will be changed too, Smaller wheels will make the odometer display a higher than real distance, and vice-versa.
@@holdshiftt2run308 That will only work for speedo’s controlled by the car’s computer. An app is going to do nothing about true analog speedo’s with a cable going right into the transmission, which this video shows.
I have a very important question about the cluster of a 2005 hayabusa involved in an accident. The rider is severely brain damaged unfortunately and is bedridden in an auspice for life. Is there a way i can contact you to discuss what i need to know about whehter a needle apparently stuck at 65mph while the cluster is completely detached from the bike (on the ground) reflects the speed the man was driving or is it possible that the needle could have gone anywhere on the speedometer plate? Also, the rpm is stuck at 1200 rpm. Is it possible. I heard that if the spring is broken then the needle can go anywhere and if it is not the needle goes back to 0 mph. What do you think? I need an urgent answer.
If the rear wheel lost traction, which happens on a Busa already when you twist the throttle too far open, the speedo can show 150km/h while the bike could actually have been going 30. Also, the fact that you are DIY-researching such stuff via TH-cam comments for something “highly important” around people with brain damage and probably legal cases, should make you realise that you are way off track for finding proper resources. This sounds more like the job of a research team of a police department.
Actually, what Richard says makes total sense. The bike of the rider who hit me head on did leave the ground and the rider went over the handle bar. Hence no traction, hand on the throttle.... makes sense. But, the other comment is also true. In my case, and it turned to be a legal battle against various actors, including the CHP and the county of Los Angeles, I found massive evidence of corruption and the case is before b the 9th circuit now for falsifying public records of accidents, their true causes, how the county of L.A, the state of California and the CHP have conspired to derail my case and countless others who didn't go as far as I did. Believe it or not, the president of division 8 of the court of appeal., Patricia Bigelow, among with the presiding judge of the superior Court, Samantha jessner, are involved in the cover up. All evidence has been given to state and federal courts and no-one wants to do anything about it. They just don't know that I am like a pit bull. I don't let go. There is si much more to say. Stay tuned. I am on about to go public on who did what with irrefutable evidence of the corruption that drains public funds, tax payer money and countless death due to lack of accountability
No the oil only would only lubricate the moving parts (cable and magnet) it would never get into the speed cup because they are not attached, they don't even touch.
Depends where you put the oil. If it creates drag between the cup and the magnet then your speedo will be messed up. A speedometer which is not designed to contain oil is likely not oil-tight.
@@mrcow202 The crankshaft is part of the engine, where the pistons are connected to, so that has nothing to do with the speedometer. A speedo measures the driveshaft which is the shaft from the gearbox to the differential.

The magnet's not attached to it. Only the magnetism itself turns the speed cup which turns the spindle.The speed cup is made of aluminum by the way, which is barely magnetic

the magnet don't have speed it works on the principle of deflection which it gets from the input....study about electrical instruments like voltmeter or wattmeter....u'll get the idea
Mijas Tiwari yes,it had been re-normalized,the analog magnetic counter isn't truthful than a real digital counter so the current which produced by vehicles is different such can change the real velocity display.
the video initially says, "magnet rotates with the same speed as that of the transmission." then it says, "the magnet rotates with a speed proportional to the ...". please correct this. good video otherwise!
I noticed that mistake as well but i let it go.. He means, the magnet speed is proportional to the vehicle speed. Of course it cannot be equal to as that makes no sense. The magnet turns (rpm) while the vehicle moves in a single direction (km/h), in math sense rpm cannot be compared to speed. But it can be proportional.

Kyle D All the fuel injected cars uses Electronic Speedometer. The speed is required by the fuel injection system in order to measurate the correct amount of fuel and air in the mixture. Some of the electronic speedometers use a needle (like the old mechanical one), others use a digital display
actually, electronic speedometers are way more reliable than magnetic ones. I never saw a electronic speedometer stop working, even in my old 1982 car. Magnetic Speedometer are more likely to deregulate over the time
+Matheus Bitencourt Mechanical speedometers are quite flimsy designs. The needle tends to sway or fluctuate with age, especialy a lower speeds below 35 mph or 60 km/h, as with mine. As the car slows down towards zero, it swings really wildly. I think this is due to the spring weakening over time.
u wrong as hell bruh.. my niece showed this and i laughed straight up.. the actual mechanism is , the transmission wire supplies current proportional to the speed and also has it rotating independent of the speed cup which produces changing flux , i.e eddies that provides a torque to the spindle - rotor system which rotates / provides constant torque that is held at equilibirium by hair spring , which basically holds it , engineered with the appropriate spring constant to display the correct reading at the dial... and you said twas magnetic field dude.. cmon bruh u have 150k subs , this is high school shit
Maybe youre pertaining to digital speedometer or tacometer. Those two have the same principle except for the speedo measures vehicle speed ang tacometer measures engine speed in terms of rpm.
"There for,(sic) the speed of the permanent magnet will be equal to the speed of the vehicle" This is so incredibly wrong, it's laughable. The speed of the vehicle is measured as a directional velocity, the speed of the magnet is measured as a rotational velocity. You cannot equate directional velocity with rotational velocity. Something doesn't rotate at 60Km/h and a car doesn't travel at x,000 rpm. This is probably one of the worst "How something works" videos I have ever seen... and that's without taking the dreadful grammar and spelling into consideration.

How to generate changing magnetic field ?
I thought it uses derivatives to find out the speed at any instant of time
How so?
@@Darkev77 because in physics, derivative is used to calculate the instantaneous speed
@@unknwn_usr3077 yes, but for that you would need to have information about the car’s kinematics (acceleration and time elapsed) to find it’s instantaneous velocity, and I believe you can’t have that on the fly.
Haha, same bro... I'm in grade 9 and i wondered how they calculated speed, i thought they use some kind of formula to do so...
How is the cable conneted to the magnet
Just by a drive square at the center
What if you buy bigger or smaller tires?
It will change the speed that is showed in speedometer resulting in mistake. Smaller wheels will make the speedometer display a higher than real speed, and vice-versa. Hodometer will be changed too, Smaller wheels will make the odometer display a higher than real distance, and vice-versa.
there are apps to help you calibrate your speedometer.

not bad. I'd like to know how the hair spring works. if the magnet spins the spindle, how come the pointer doesn't spin along with it?
The magnet's not attached to it. Only the magnetism itself turns the speed cup which turns the spindle.The speed cup is made of aluminum by the way, which is barely magnetic
the spring stops its from spinning with the needle
The further the spring gets compressed (=the higher the needle goes), the more resistance it gives to the needle.
