I have a 94 Dodge Dakota where the tachometer was failing. Upon startup the needle would float and then go full clockwise deflection, settling on the overdriven section of the meter. I pulled the old drive module from the back of the instrument cluster and began troubleshooting for bad parts...
Hello all,
I have a MINI Cooper S tachometer and would like to control the unit via a microcontroller. I have worked with microcontrollers before but have not done anything yet with car electronics.
Any ideas on how I could find any pinout, schema, or datasheet to this device?
My old car uses a 1mA current driven tach movement and the stock circuit isn't compatible with the MSD ignition box I use, and the adapter they sell to make the tach work buzzes like the dickens.
So I worked up a tach circuit based on the current tach diagrams in the LM2907 datasheet that'll...
Good morning,
i am currently attempting a university module looking at reducing vibration in a helicopter.
i have access to a "model" puma helicopter that is used to record and change track and balance of the Main and tail rotor blades, i am looking at attaching a tachometer to calculate the...
