Hello, I am hoping for get your help with implementing a very simple (I hope) divide by 2 circuit. I am not an electronics guy by any means, so please bear with my ignorance. I did a bunch of searching first, and the threads I found seemed to be regarding implementing more complex devices and started to go over my head. I'm hoping this will be simple and quick for me to build/buy myself.
The problem is making the tachometer on my motorcycle read correctly. I have installed an aftermarket engine management controller to replace the original one, and the tach output signal from this computer is exactly double of what the tachometer expects. I need to cut this output in half to get the tachometer to read correctly. Ideally, I would like to build/get a little device that I can wire up inline with the output wire between the tach and the computer. The trouble I'm having is where to find such a device.
Through my googling, it seems like I'll need a "d-type flip-flop" circuit, is that correct? If possible, I'd like to build this with either stuff I have lying around on-hand, or something I could go to my local electronics store and pick up.
I currently have a few chips lying around that I was wondering if they would work for what I need. "SN74HC373N", the datasheet I was able to find with searching: http://www.chipsinfo.com/TI/SN74HC373N.htm Does this have what I need? Or would there be a more effficient/simpler way to go about this? I don't know what sort of signals or wires I'd need besides the source pin from the tach output. I have readily available ground, +12V and +5V pins.
