I have lost my way in the world of software and its now time to brush the dust off my interest in building hardware
I wanted to learn how to use a 128x64 pixel display, i.e. the DOGM-128-6 from Display Visions. I then got distracted by the requirements of the LED backlight. For several of the backlight options they suggest some series current limiting resistors for 3.3V and 5V. For the White, Blue and Full Colour backlights, they suggest … Continue reading Testing Constant Current Device BCR421UW6
An experiment is two way to write and read data to IO. This features using the MaxiMite2 to help with driving the shift registers.
The local open lab sent out a call for ideas to run workshops over the lead up to Christmas. I thought of a Christmas tree with candlelight LEDs. I needed to know what was involved in making such a model before I could conduct a workshop. In this post I describe the that approach that … Continue reading Getting Started on Christmas Workshop Idea
I became interested in a LED display I saw in a beer garden over Summer. The remarkable thing was that it was clearly LEDs on a bus of only two wires. Even so the LEDs were able to be animated such that they could blink in unison or every other alternatively. I was intrigued as … Continue reading Bidirectional LED Driver
I have looked into using Neo-pixels strips and I was really impressed with the simplicity of use. Now I was curious about controlling a matrix of individual, non-addressable RGB LEDs. So I searched out a LED Matrix driver that looked like it could handle RGB LEDs. My search ended with the IS31FL3736 12×8 DOTS MATRIX … Continue reading RGB LED Controller
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
Some Background I recently had the opportunity to revisit an old project of a doorbell extension that used the ELV FS20-S4SUB to send a signal to the ELV FS20 SIG-2. At the time I did this with what I knew at the time to get the job done with the equipment I had. This meant nothing … Continue reading Revisiting an old project
