Awsome D.I.Y man.Hope i will be doing all these stuff after my B.E

(I am doing it in Electrical branch)

Great work there buddy! :cheers:
Normally a person doesn't take so much pain for a tacho.
Good job and keep it up.

As said by somebody earlier, some good pictures are very much in need here.

Thanks everybody.
@IMP
Yes it uses a PIC 16 MCU. The programmer that i've built is JDM based programmer by Feng (google for it). another reason for using PIC MCUs is that u get them free from Microchip.

@speedzak,
i'll post a better pic soon. actually the casing doesn't looks great - its just there for testing the circuit in the car. i'm soon getting a case fabricated by acrylic (thanks Sudipto for help) - then i'll post a pic of the unit which will look truely professional.

Will this work on a Carb ZEN ??????????

archat68 · 4th July 2007, 07:33

yes it will. u just connect it to the low voltage input at the ignition coil.

Cool stuff Arup....and another Designer/Entrepreneur in the making. Keep going dude and every major innovation starts with a single step and i guess you would rock some day.

Nice. Real nice. Especially liked the programmable slider for shifts.... Now, perhaps you could program it to display revs in increments of 10, instead of 100...

It is taken from the spark plug sir.

I believe that would be the spark plug WIRE, or the ignition cord, eh....you could also take variable i/p from the alternator (like for the regular tachos)...but I dunno how that would apply over here....

hey could anyone tell me how to fit a stand alone shift light(sard) on a swifti seem to have misplaced the manual!

speed0mania · 6th July 2007, 15:18

anyone!!?? or does anyone know of someone in delhi whose capable of doing it!!

Interesting project. Has any one done DYI digital Speedo and fuel gauge for their car. I have a carb Zen MH410 (98 model) and would like to add some DIY digital stuff to car.

Please provide me the link

Thank You

@archat68 great work there and am sure you should be looking at mass production here as a D.I.Y like this for just Rs.200 is awesome.
Keep up the good work we would love more inventions like this from you in future and such D.I.Y jobs would be tremendously appreciated by all.

SirAlec · 11th June 2008, 21:14

dude ! can you provide the schematics.
Thanks

Thread awake after a year, Great! Can a guy zero in electronics do this stuff? Got a display like that lying around.
