First, greetings to all. This is my first post. I have a dirbike that I converted to street legal. I pretty much ride it just to commute back and forth to work, but sometimes I just go for a cruise anyway. Although speedometers are NOT required for these types of conversions, I want to build my own digital speedometer just for a reference/general idea of my speed. Odometer would be cool too, but I know the miles I ride to/from work and I can use google earth to figure out any other miles when I go for a cruise.
Here's the parameters of the situation. My bike has a 12v system with plenty of power (battery and stator) available, negative ground system. I have a place to mount a digital readout, which can be attached to the board or not, with an area of 4.5"Width x 5"Length x 3"Depth or Height, whichever you prefer. Routing wiring of any sort is virtually up to my imagination and unlimited pretty much. I have several places I can install a magnetic pickup sensor of some sort and a magnet or magnets to trip the sensor. My skills are at the "beginning hobbyist" level of electronics, I can wire, solder, I have basic understanding of circuits and components, wiring diagrams and I have built a couple of circuit board "project kits" that can be bought at electronics stores. My background is aircraft maintenance and automotive racing, so physical and mechanical stuff is no problem.
What I need is a two digit digital screen. A circuit design with what would be required to convert the sensing to digital readout. Programming language (which I know nothing about) for the conversion. Lastly, I would need an idea on weather proofing the end unit, because rain doesn't scare me and it rains a lot in Florida.
Now, to add one last thing. I'm not a big fan of questions like "why are you doing this?", I can tell you why. This is AMERICA and I'm doing it because I can. I like small projects and doing stuff myself. I don't like the idea of paying some douchebag $199 for some made in china piece of crap that can only be done "THIS WAY" because it was made for something else. Being a converted dirtbike, there is virtually nothing made as a "bolt on" accessory that is not too expensive and complex. There are computer units out there but they have too many functions and BS for what I need and I'm not going to pay the high prices for stuff I don't need.
