| sir i want to know if this can be integrated in a mechanical electric meter. and how reliable it is in measuring the rotation of a disk in that particular meter. thanks..please do reply. | ||
| I like the circuit. I have been drinking every day for weeks and consequently, I am out of money. Please send me a built circuit and some money so that i may drink and continue with school. Thanks and please hurry. I have a final coming up and there is a wicked good band at the pub down the street and I need beer money and also have no time to work or build this circuit. i will submit this circuit as my own design. Hope you don't mind. Thanks again. | ||
| sir, i am doing final yr ECE,i like automotive electonics,so i am going to do a project in dis field, i want to know all the details of the wireless auto tachometer with all the relevant details like circuit diagrams, the principle of operation and the list of components required in the diagram,project paper.I would be very thankful to you if you send me the above details to my e-mail id as soon as possible. Thank you sir. (Editor's notes: Did you even read the page?) |

| I am truly amazed at how many of the people placing a comment is willing and able to rip off an idea for which they can claim no credit and pass it off as their own. If you are "studying" electronics study the circuit and draw you own conclusions you lame leeches. Out | ||
| hello sir...I want to know all the details of the wireless auto tachometer with all the relevant details like circuit diagrams, the principle of operation and the list of components required in the diagram,project paper and also coding for the programming..I would be very thankful to you if you send me the above details to my e-mail id as soon as possible so that i can use it as my reference for my final year project.. . Thank you sir. | ||
| I like the idea of this circuit, however the circuit itself is not designed very well, you basically have to keep calibrating it constantly because it's very sensitive to temperature changes. | ||
| interesting design I am curious if this might also work with a coil of wire wrapped around a specific plug wire or should it be the main ignition coil? | ||

I'm a final year student and have taken it as my project. Thank you sir. | ||
| Hi, I'm a student and therefore spend my time drinking, playing role games on my daddy's PC, and practising advanced onanism. Can you therefore send me all details of this project, properly written and bound and, of course, a ready working prototype so I can present it as my course project and get top marks. Right on man... | ||
| hi it is usefull to all electronic related people but sir i can try on this project on my bike single cylinder. how can be possible please send me full details or sir i lived in india use 220 volt 50hz power .if it is possible please send me related details i am very thankfull to you.ok | ||
| can another resistor be added to have this work on a 2 cylinder Harley Davidson motor? | ||
| I have been a Product Design Engineer for 28 years now, and find the Wireless portion interesting. In Reality, you still must hook up a Power source, and for any moving vehicle, It's just as easy to make the other connections as well for a hard wire connection, and without having all that Radior Frequency Static. Now for a Generator or Stationary Engine, this would be great. | ||

| is there a way to use this with an internal combustion engine that has only one cylinder (i.e. motorcycle engines)? i'm really interested to put this in my motorcycle. please enlighten me, sir. | ||
| The above calibration procedure is for 60Hz AC. Calibrating using a 50Hz 12VAC transformer If your mains power is 50Hz, set up as per the calibration schematic above, and use this procedure: Set S2 to 4 cylinders and adjust R5 for a meter indication of 150 (1500 rpm). Set S2 to 6 cylinders and adjust R6 for a meter indication of 100 (1000 rpm). Set S2 to 8 cylinders and adjust R7 for a meter indication of 75 (750 rpm). | ||
| Hi, interesting project, well done...but will the person/s posting multiple requests under diffrent names please stop. If you have course work to do, do some research and learn something and stop trying to leach some easy grades, also it will help if when requesting that you do not use such a demanding tone as people dont like this. If this work would be used as course work then whom ever uses it should have a sound understanding of how it works just by studying the diagram, if not then it is to advanced for you to be using in your work.

| hello sir i have been looking at your wireless tach and have choose to do it as a project ror my electronics class could you please send me details on this project thank you | ||
| Very nice!!!
I was seraching for a signal conditioning circuit, to sense RPM from the engine.
I'll use this circuit to feed pulses to a micro-processor and capture RPM digitally (torque curve up to a scale factor) (Editor's notes: Also look at the schematics of the Megasquirt project.) |
||
| sir i want to know the detailed working and design of this wireless auto tachometer. can you please send me all information related to this. i will be very thankful to you. | ||
| Hello, sir. Given the fact taht my original car tachometer doesn't work for more that 2 days and i'm really sick and tired of fixing it, I want to build your design. The only problem is that I live in Europe and here we have 220-240V @ 50Hz at mains. Can you please tell me how to calibrate it in these conditions ? Thank you. | ||

| hey, can u send me the detailed explanation and process involved in construction of the above project ??? .... please !! | ||
| I've built it and found it perfectly functioned as well | ||
| I haqve a six volt positive ground system. what R values do I have to change and will circuit operate as shown as long as I connect pos and neg accordingly? | ||
| hi,ur ideas are very innorvative. cud you if possible send me all the notes for this project.i would lyk to intergrate your idea so that it may be applied elsewhere | ||
| Better give some explanation about the design of the circuit for those looking at these kind for the first time. | ||
| Applications? | ||
| can you help me make a tachometer for my motorcycle (single cylinder) and make a digital readout for that without any micprocessors involved (analog gauge is also GOOD) | ||
| I'm looking for a wireless for an ATV one cylinder four stroke, do you have anything that will work? | ||
| if i want to see mor detail about this the wat i have to do? plz suggest me | ||
| what does the tachometer do! and what does it measure? how can it be used? because i have made a beach buggy | ||
| Sorry, i'm beginner in electronic. What is M1, is panel meter or amperemeter ? | ||
| Very simple and perfect circuit for to have an idea of RPM in my van !!!! I will calibrated with real tachmeter and make new back-face of M1 to use it. | ||
| Could you send me more information about the instaltion and use of the tach? | ||
| IT'S WORKS | ||
| im having trouble reading the schematic because its very blurry also please explain a2? thanks | ||
| sooped up work men! | ||
| i have not try yet, but i had look this circuit, and I will analysis | ||
| HOW WE MEASURE THE SPEED IF WE ARE GOING TO USE TECHOMETER? PLEASE SEND ME EMAIL TO MY ID. | ||
| Does this unit also work with diesel engines? Can I remote it's output screen to my instrument panel? | ||
| what is the rating of battery | ||
| Can the tach be adapted for a one-cylinder engine? Why are D3 and D4 in series? Don't they do the same thing? Similarly why are R10 and R11 in series? Wouldn't a single resistor of 17.2K do the same thing? Thanks, DMG | ||
| Can this be modified for a single-cylinder engine? It would seem to me that the rotary switch could be eliminated and a single pot could replace the three pots. Any ideas? | ||
| What reading will be shown on meter. Do we have to multiply it by some factot like 1000 or so. What about a 3 cylinder engin. | ||
| where is see rpm of engine in circuit | ||
