The heart of the switch controller is an Arduino Nano micro-controller - this is going to be the interface between the dashboard switches, wireless steering wheel buttons and the car`s lighting, indicators, windscreen wipers and DigiDash2 GPS stopwatch. This should make it easy to have self-cancelling indicators, intermittent wipe, auto wipe on wa

sh, plus can use multiple button presses to choose sidelight/ headlight or wiper speeds - any logic you like, really since its all software controlled. Also removes the need for any electronic hazard flasher or ballast resistors with LED lights, as the MOSFET should handle it all. I`ve started on the wiring schematic for the controller - first time I`ve used MOSFETS, so should be interesting - any electronics enthusiasts please feel free to critique. Next step is to mount the voltage regulator and input/ output resistors on a stripboard and get the thing cased up, then put the transistors/ MOSFETS on a large heatsink that will attach beneath the scuttle somewhere and sort out the wiring mods to the Westield loom. downloads: 103 I realised that it would be easy to use low-side switching on the wiper motor as the ground is accessible - the circuit is simpler and high current N-channel MOSFET`s are cheap. I`m going to start testing the circuits and writing the code this weekend hopefully. If I find anything wrong, I`ll update the schematic in case anyone else plans to use it ;-) 29/12/13 Finally finished! I made a few changes to keep hazard and sidelight circuits working with the ignition off- the Arduino effectively just replaces the indicator switch and controls dipped and main beam relay. I also added a reed switch with single magnet on the steering column to cancel the indicators. So a single indicator press will switch on...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
