New Gate Monitor Position Switch FINALLY Installed

I printed the box for the new switch last December, but since the weather was bad and the gate is locked closed in the winter there was no sense trying to install it. And once something is on the back … Continue reading

Another Successful 3D Print

The magnetic reed switch I put on my gate sensor has been problematic. There are several inches of play between on and off. Since the reed switch is on the hinge side of a 20′ gate, that translates into the … Continue reading

Gate Monitor Installed on Gate

It was a long afternoon getting the gate monitor connected in to the gate, but I expected it to be slow going. Interfacing to the real world is always messy. Overall the install went well. Everything is wired and tested. … Continue reading

Gate Monitor Printed Circuit Board Complete

It took all of my spare time this weekend, but I got the PCB printed and populated. It looks pretty good: It’s getting late so I won’t test it until tomorrow. Hopefully there are no really bone-headed mistakes. My first … Continue reading

Gate Monitor Board Laid Out

I laid out the printed circuit board yesterday. I’ll give myself a week in case any new ideas / fixes occur before going through the trouble of actually building the board. Although the software is ‘done’, I’ve already thought of … Continue reading

Gate Sensor Fully Breadboarded

Added in all of the supporting circuitry to allow the gate sensor to be connected directly to real hardware. So transistors were added to allow interfacing to devices that draw more amperage than the arduino can support like the beeper … Continue reading

Gate Sensor Software Written

I wrote most of the gate sensor software at the Spokane hackerspace last night and wrapped it up when I got home. The rules are pretty simple: If the gate is left open too long start beeping A push button … Continue reading

Gate Sensor Test Circuit Bread Boarded

This past week I was able to get a test circuit for the gate sensor bread boarded. Unfortunately my laptop was down all weekend (and my time was all wasted on rebuilding it), so no software was written. Right now … Continue reading

Gate Position Sensor R&D

My back gate is an electric swing arm gate. Great for getting in and out of the back driveway without getting out of the car, but occasionally the gate doesn’t close. Most of the time it is my own fault, … Continue reading
