Driving the WS2811 at 800KHz with a 16MHz AVR
Recently some of the folks at the Manchester Hackspace did a bulk-order of WS8211 LED pixels. These are available from several vendors on aliexpress.com (search for "WS2811 5050 RGB") and they combine a 5050 RGB LED with a WS2811 driver chip. The WS2811 ...

As it says, "Beautiful light performance"
Well, we did our first performance with the LED strips on Wednesday at Islington Mill in Manchester,and I'm relieved to say they worked flawlessly, even after one of the wheels was dropped just before the performance started! The lighting in the venue ...

Connecting a HL1606 strip to an ATmega
I've been left a comment asking how the HL1606 strips are connected up to an Arduino. The wiring is really pretty simple, but depends on exactly which ATmega version you have, as the hardware SPI pins vary from MCU to MCU. The following assumes it's a ...

I'm wheely pleased...
Last night I met up with Andy and Colin of The Travelling Light Circus at MadLab to finally finish off some the LED strips that I've been working on for so long. The original plan was for them to be worn, which would have meant splitting the 4 20-LED ...

Radio-controlled HL1606 strips
Well, I've finally finished the design and implementation of the radio-controlled LED strips I've been asked to make for The Travelling Light Circus. It's taken far longer than I expected, but I've learned an immense amount in the process. The ...

Waiting for O(1)
Due to a misconfiguration the notification emails from my blog weren't reaching me, so I missed a couple of interesting comments on my earlier HL1606-related posts. The ones from Dan from over at Waiting for O(1) were particularly interesting, and he's ...

Characterising the 7805
As the LED strips are going to be mobile, I needed to find a way of powering them. After some investigation, the 7.2 volt NiMH battery packs used by radio controlled cars seemed like a good choice - they are high capacity, relatively cheap and readily ...

Bidirectional patterns with the HL1606
Most of the videos on YouTube of the HL1606 being driven with an Arduino have patterns that start of the controller end of the strip and propagate to the far end, for example this one. I'm driving patterns in two directions, and even outwards from the ...

How the HL1606 REALLY works
I've explained in my last two Arduino posts how I got the HL1606 working with the Arduino's SPI support and hardware timers. If you haven't already read them, I suggest you read at least the first post before this one, otherwise what follows won't make ...

Driving the HL1606 using the Arduino's hardware support
In my last Arduino post I explained the basics of how the HL1606 works, if you haven't already read that I suggest you read it first. The google code library that drives the HL1606 does so by bit banging the control lines. That's both slower and more ...

How the HL1606 works
I've been asked by The Travelling Light Circus to make some radio-synchronized LED strips for them to use at the Big Chill Festival. I'm using 5V multicolour strips that I'm going to control with an Arduino. The strips are driven using the fairly ...
