Cheap high tech for home modders

[andyvh1959]

Some of us like to try and mix parts from other Kawwy models, maybe from other bikes and brands. These days that can require getting to know what signals you get or need to get components working. Decades past that meant you had to be a television techy with an oscilliscope. An oscilliscope is a very expensive electronic device that can see and analyze the signals generated by electronic devices.

But, these days we hold amazing power in our pocket (not THAT), our smart phone. And there are apps for turning your smart phone into an oscilliscope! I got to thinking about this because of apps to use your phone as a sound meter. The phone takes the input from the microphone and a sound meter app produces the waveforms relative to the sound input. Some persons much smarter than me took that steps further, using an input jack from a old set of headphones (the four segment jack), two resistors with a ratio of 1:10 between them, and a downloaded oscilliscope app and your smart phone now becomes an electronic analysis tool. Way cool for us home techies:



Here is a guy testing the wheel speed sensor on a car:



Here is one that includes an adjustable range controller:



In the case of, say, trying to match the speed sensor output from a VN1600 to the input required to using a VN1700 speedometer, this device will let you "see" the magnitude and frequency of the speed sensor output and determine if it is correct or can be modified as needed.
