Reverse engineering Jacob Jensen P-watch: Part 1
This christmas I got this Jacob Jensen’s P-watch as a gift and thought about whether or not to install it in my car. I decided to try it out – but after three weeks of hell I took it out and bought an old manual P-watch. The automatic P-watch works by measuring vibrations of the car and deciding the parking state from the internal algorithm. However it does NOT work as originally thought! Every single day when I stop at the end of the highway, the parking watch beeps and think that I have parked – no, I’m not just saying every day for fun. It was every, single, day when I stopped at the end of the highway .. I could just sit in my car and say “now it’s gonna beep” – and it would. Beside the wrong parkings the people behind the electronic P-watch have decided to “lock” the P-watch after a while, so you cannot manually set it. So often when I was out driving and needed to park I had to reset the P-watch, manually set the time correct and then manually set the parking time afterwards! This is NOT good for a parking watch costing you almost 200$.
I wrote to Jacob Jensen about my 90% error rate and irritation. I got redirected to the manufactoring company (from the design-company) and was promised an answer in a very short time – now almost two months later I have still not received the response.
So what to do with a shit-watch that is to more annoyance than help? Well.. if I could juuuust reverse engineer it
