I have lost my way in the world of software and its now time to brush the dust off my interest in building hardware
Introduction I have written about the Timed LED Lighting Controller in previous posts. Starting with the original entry “Stairwell Foot Lighting System”. In this entry I will be wrapping up the project and describing the change of direction from the initial design and layout. There may be a bit of overlap but it will be … Continue reading Wrapping up the Timed LED Lighting Controller Project
For a while now I have been intrigued with Integrated Light Sources i.e. NeoPixels. I knew nothing about them and with the coming of Christmas, I was inspired to take a closer look. I knew I would not have anything in place before Christmas 2017. But there is always next year. Design I wanted my … Continue reading A Look into Integrated Light Sources
It has always been on my list to try a project with some wireless communication. I now have a project in mind but there are a few things to sort out first. I have not worked with any wireless at the embedded hardware level. This is not inteded to be any instructional post but my … Continue reading An Encounter with XBee
In the last entry for the Timed LED Lighting Controller, I realised that there are no working examples of an I²C driver for the ATtiny20. I then had to work through the data sheet to implement my own. With that done, I could then start on the application firmware and get the board really working. So … Continue reading From Proof of Concept to Prototype
In this post I describe the trials an tribulations of bringing up my Timed LED Lighting Controller and how I went about implementing my first I²C Slave Driver for the ATTiny20. I was keen to receive the boards for the Timed LED Lighting controller to know if they would fit in the chosen housing. The … Continue reading Back to Blinky
In the last post for the Timed LED Lighting Controller, I had figured out the circuit and a basic layout and approach that I was happy with. That is to separate the hazardous voltage from the control circuitry by putting it on a separate board. But still, this was not enough. I need to assemble … Continue reading “Mocking” – Minimising Risk
From Logical to Physical Before I could start to translate the block diagram into KiCad, I needed to be sure about some of the parts I will be using. I want to reuse what I already have installed, so the motion detection module is already a given, along with the LED drivers. The micro controller needs three … Continue reading Timed LED Lighting Control – Design
When getting back into electronics, one of the projects I had in mind was to revamp our stairwell lighting system. In 2010, we renovated our stairwell. I took the opportunity to design in a foot-lighting system that was motion controlled. It has worked faultlessly for the last six years. But who can stop at revision … Continue reading Stairwell Foot Lighting System
It has been a long while since the last post. Amongst other things, the clock has been a work-in-progress. Each time I made some progress, I found some new reason to create a revision. The initial revisions where based on issues and oversights. I am finding that as the project matures, the nature of the … Continue reading Wrapping up the Alarm Clock Project
I created the main board in the same pattern as the original. That made for quite an expensive prototype as there is a lot of empty space. This size is needed to fit the tactile switches in their proper places. Now that I have Revision 2 up and running, a write up of what I have … Continue reading The Main Board
