    TIM-6 ignition > Arduino

    I have an electronics problem I could do with some help with. I would like to take a tachometer interrupt signal from a Jerry Howell's TIM-6 kit for an Arduino Uno based engine management system and display. Initially, I thought I could simply parallel the LED on pins 4 & 5, but now a...

Although the great majority of the original castings would have been iron, the model castings are aluminium alloy. Also the original would have been painted, but I am not going to do so...

    Hello people. This is my first post in this neck of the woods. I live in the UK, West Midlands area. I have been doing model engineering for many years, but am currently tackling my first petrol engine. It's a Westbury designed 10cc twin side-valve job, castings from Hemingway Kits 1. You can...
