My windows switch modification for automatic roll-up windows became a very popular mod among Miata enthusiasts. However, the original modification, for most people, was somewhat difficult due to high precision soldering. To make it more accessible, I designed an external controller with a wire harness, which is now an easy plug-n-play setup.
My initial blog 3rd Brake Flasher was about using an accelerometer and plug-n-play setup, with a low-cost popular GS-100A flasher. I got a few requests about an option without an accelerometer, but with some delay feature, so it would not be so annoying in stop and go traffic. The challenging part of such a design is there isn’t constant power. Power is available only during brake application. To solve this, I have added a couple of big capacitors to my design and optimized it for very low power consumption, so the microprocessor can stay powered for an extra 10-15 seconds after every brake application. The 3rd brake light will blink 4 times after the initial brake application. If intervals between brake applications are less than 10 seconds, it will simply pass through brake status.
This design option is available from my store.
Installation of a dashcam is usually a simple process, with some hassle of routing the power cable under the plastic trim. In most cases, the camera power cord simply plugs into the ACC outlet. Continue reading
The Mazda MX-5 (ND) has one annoying issue. As soon as you shut off the engine, the Radio/Bluetooth system immediately turns off. This is especially annoying when you are on a call, but have to stop the car in a parking lot or garage. Most other car radios will continue working until you open the door to exit.
The front bumper of the MX-5 Miata is very low. Some people even lower their car more, by an inch or so. A front parking camera would be very useful, to avoid scratching the lower part of the bumper while parking close to high curbs. Continue reading
The MX-5 turn signal clicking sound is very quiet. Often times when driving with the top open, it’s easy to forget to turn it off. There are a few discussions and solutions on the Miata forum about this issue. Continue reading
