During the last two months, i received some comments from a pcbheaven reader with the id Qla regarding my PIC Frequency-Change Capacitance Touch Button. I was happy to see that Qla was inspired by this project, and made himself some touch buttons for his car. He planned to use SMD components, but in the meanwhile he made a batch of them and they were small enough to fit behind the blind buttons of the car. He made 4 toggle switches and one temporary make button with 3 seconds off-delay. Here is a video from one touch button:
He made some changes to the software, and after 5 days of trial and error, the buttons worked fine!
After 5 days of tests in my car I can tel it works very good (in my town more often I stand in traffic than ride so have a lot time for tests :) ).
Each button is interfaced with a 1.5A relay to drive the loads. Here is the video with his project.
