Whilst I await delivery of more WS2812 LEDs, I wanted to start investigating how I can leverage the Alexa Gadget Toolkit integration, so that when I set a timer using Alexa, my LED clock can show the countdown. Amazon make an Echo Wall Clock which does just that. I found an open source project called … Continue reading LED Clock, Part III: Alexa?
I managed to rework the time calculation and hour hand movement! https://videopress.com/v/jndhVFHI?muted=true&persistVolume=false&preloadContent=metadata The clock is ticking! I removed the RTC component and just let the loop run, with simple counters to simulate the passage of second, minutes and hours. I think the transition of the "hands" needs to be smoother, more analogue. I'll have to … Continue reading LED Clock, Update!
In Part I, I covered the basics of controlling the LEDs. This covered the hands of the clock. The second part of my investigation covers time and how to make the clock tick. The ESP 8266 I am using for this prototyping work doesn't include a Real Time Clock, so I was required to add … Continue reading LED Clock, Part II: Tick, Tock
The first part of making an LED clock was actually learning how to control the LEDs in the strip. I had experimented with the LED strip before, flashing a rainbow, before realising I had no practical use the damn thing. At the time, I had used a Neopixel library. Upon googling the subject again, another … Continue reading LED Clock, Part I: Hands
A year or two ago, I picked up a WS2812B LED strip, but, for the life of me, could never think of anything useful to do with it. Recently, however, I came across these LED powered clocks. https://youtu.be/5c7LYEAVJHg https://www.youtube.com/watch?v=4ZatJAPwI_4 https://youtu.be/JNpjX5mobfI This feels like a project that will combine a few things: ESP MCUReal Time ClockWS2812B … Continue reading Lockdown LED Clock
A common occurrence in our house is bath time. Another common occurrence is not having enough water for afore mentioned bath. Our hot water is provided by a system boiler/unvented cylinder arrangement and I use a Nest to control the hot water (more on that later). The current schedule has it running the boiler for … Continue reading Do we have any hot water?
As part of my Temperature Sensor upgrade, I've started looking into Mesh Networking support. Documenting my progress Rather than try and put a post together at the end, I'm going to try and document my progress as I go, with additions to this post each time I do something significant. The beginning I recommend you … Continue reading TS MK II – Mesh Network Pt.2
As part of my Temperature Sensor upgrade, I've started looking into Mesh Networking support. I was aware that the Expressif ESP32 supports the new Bluetooth LE Mesh protocol, and as Bluetooth Low Energy would help stretch battery life, it seemed like the natural place to start my investigations. I was initially going to try the … Continue reading TS Mk II – Mesh Network Pt.1
