In this blog post I explain the microcontroller firmware that emulates candlelight in more detail. You can apply the explained techniques in similar situations to get organic effects on CPU and RAM-limited platforms. I will focus in my description on emulating a convincing random effects with minimal resource usage. Demo The following video demonstrates the…

Adding a Light Barrier using Epoxy
As you read in my last post about the pet-feeding device project, there was an issue with the fill sensors. The lines from the 3d-print transferred the light directly to the sensor and made a useful measurement impossible. One of the solution to this problem is a small gap between the LED and the sensor….
Always-On Firmware Example
Recently I published a simplified version of the Always-On project hardware. Read this post for details. Today I publish a firmware example for the Always-On project. This firmware is written for the PlatformIO environment using Visual Studio Code. It is using a special adaption of my HAL layer for PlatformIO using the Arduino layer for…
Candlelight Effect
Here I briefly document a very realistic candlelight effect you can build with very few components. It works best if the device is placed in a jar or behind a screen, where the Neopixel ring is not in direct sight. You will find all the required information, schema and the firmware to build the device….
The Five Light Spheres Project
I just published the guide for the five light spheres project. It is the perfect decoration for this Winter. The spheres always display a nice color combination and blend from one color to the next. It is a quiet and artful decoration. Continue reading on the project page
How Build a Beautiful Table Light
I just published a new project, how you can easily build a nice table light from a cheap candle holder you get in any IKEA shop. The project is using a NeoPixel ring and a Adafruit Trinket as microcontroller. The microcontroller is very limited, but you will find ready made software which will get most…
