So, the thing that finally got me to start this blog is an idea that has been rattling around my head for a while
The idea started when I read this post on hackaday. What could I do with a distance sensor?
I started thinking about mounting it on my bike, so I could use it to know when cars get too close. This lead on to the idea for a cycle mounted computer as a sort of black box.
I used to have a simple cycle computer, but when the battery went flat I had a smart phone, which allowed me to download an app to turn the phone into a cycle computer. This actually does most of what I could possibly want from a cycle computer, and yet I find myself not using it. So from there I started seriously thinking about this idea. What would I need? What would I want it to do?
Lots of ideas for it rattled around my head, and the distance
sensor idea actually got abandoned fairly quickly (I can normally tell
when a car is too close without the aid of technology). The next problem is although I work with computers I haven't actually learned anything much about electronics, I'm a complete novice, so building a cycle computer, a portable power supply for it, and all the gubbins needed to get it working would be a challenge. But that's ok as I would have to learn some practical information about electronics, and learning can be fun.
So the stage I'm at now I still don't have a fully formed idea of what I want, or what I would need. I know I would need some form of speed sensor, and GPS would be nice, the GPS would be able to act as a speed sensor (as it does in my phone, when I actually use it). It needs some method of recording trips, and it needs to be simple to set up, turn on, and get running. A display of some sort would be good. Obviously some sort of power supply. A central way to control the lights would be a nice to have.
I think I'm going to cheat somewhat and base this project on a RasberryPi if I ever start it. But beyond that I'm actually not very far through deciding what I am going to build.
So going forward, the first task I need to set myself is to acquire a RasberryPi, and some toy electronics kits, and start playing, to see what I can do I suppose.
