BBQ automation – a small problem

I hit a small problem – where the fan assembly will not fit into the air intake of our Kamado Joe.

This is the air intake


And this is the universal fitting end of the fan assembly


The problem is that the hoe for the fan outlet is just too close to the top of the metal sheet, and catches on the ceramic of the barbecue itself.

I need to get another metal sheet of the same size and centre the hole on this.

The BBQ automation is coming along

I’ve now got the core controller and software up and running :


Took me a while to understand that the micro controller has no software as delivered, it is actually uploaded the first time you boot the Raspberry Pi part of the system. As soon as I discovered that the rest became significantly easier.

So far only one of the printed circuit part was mounted wrongly (I did not read the installation instructions correctly – so I soldered it on to the wrong side of the board).

Now on the adding the fan and the 12V power supply.

How to remove HDCP from HDMI signal …

Interesting article on how to remove HDCP from HDMI when watching movies using HDMI.


Btw. IMHO HDCP is creating way too many problems – more than it should. – How to remove HDCP from HDMI signal …: “”


I’ve been playing with ambient light for my TV for a while now, as you can see in the “Ambient TV lighting with XBMC Boblight, OpenElec and WS2811/WS2812 LEDs“, to make colorful lights (LEDs) light up matching the video you’re seeing on your TV.

The downside of that project is that it only works for a dedicated HTPC running for example Kodi (XBMC).

But what if I’d like to see this with video from my XBox 360, XBox One, Wii, or … Blu-ray player or cable box?
Besides the fact that we need to grab this video, and all it’s technical complications, we will be running into a copy protection issue called HDCP, a HDMI feature nobody really asked for.

Please note that I’m not writing this article to promote pirating content! This article is solely aimed at using non-HDCP compliant equipment with equipment that seems to require HDCP. So I’m looking at older HDMI LCD/LED/Plasma TV’s, HDMI Projectors, Game Recording (PS3), taking screenshots for documentation and/or articles, and of course my own little project to generate ambient light behind my TV! Please keep this in mind.
