My self-made tachometer

Hello together,
i want a tachometer in my F100, but it has the cluster with warning lights and the 1980 blue printed circuit. The conversion are to expensive for me (complete cluster, new wiring, sending units...) Now I've experimented a little with Arduinos and the result is a self-built tachometer that is flat enough and fits directly into the cluster.  The task wasn't easy for me and I didn't know if it would work. Here are a few pictures: The first tests with Arduino, a h-bridge, a X27-168 gauge stepper and a signal conversion board.  After a lot of try and error i put it together.   At next i put the gauge stepper in the original cover.   Does anyone need a number?   The needle was carved from a piece of plastic.  Here the problem, no space!  but it fits  and work.  The best of all: Arduino pro nano 3$ X27-168 stepper 7$ H-Bridge drv8833 3$ Numbers 12$ resistors, cables transistors around 5$ adds up -30$  Cory, many thanks again for your original 4500rpm Tacho, i hope it's OK if i sell it again (in Germany). have a nice day everyone Max |

Yes, WOW! That is cool!
 Would you mind having a how-to about that? Like the circuits and the sketch?

big thanks
 . I will summarize everything, part numbers, circuit diagram and the sketch and then put it online for everyone.

That's ingenious!
And it looks great. Subscribed (and I think I know the girl in the beret.  )
