I have begun designing the schematics of the first prototype. There are many features that I would like this device to accomplish, but some of them will not be feasible, and many of them will not be included into this first prototype because it needs to initially be simple so that if there are problems, they can easily be ironed out. More complicated features will be trialled out in later prototypes. It occurs to me that I should probably be saying what these features I would like to implement are, so I am going to put a list below this paragraph, but also put a list I will keep up-to date on GitHub here. I would very much appreciate if people interested could suggest on features to add, after all this is a device for people like you reading this, so I would like it to be as tailored and equipped as possible towards your needs whilst still remaining relatively low in cost - you want power usage monitoring? Suggest it as a feature. Maybe if there are enough suggestions we can hold a poll to see which ones should be included in the next revision.

Suggestions:

• Clap detection circuit
• Current flow detection (detect if the bulb is on or not, switch state, blown bulb, etc.)

On another note, I am developing this project under Creative Commons 4.0 SA license, which you can read here. So, if you want to take the designs posted here and use them, commercially or otherwise - go ahead, providing that you give credit and also share your designs under the same licence.

I have also finished rebuilding the power circuit from the datasheet on the LNK304 from here, into Kicad. This is how I intend to power the device from the lighting mains circuit.

Also, for anyone interested, I am using Kicad primarily because it works on the Raspberry Pi - I make most of my update on a computer, but most of the schematics are made on my Pi because no-one else needs to use it so I can take my time. This also means that I have to use an obsolete version of Kicad, but luckily the newer versions are backwards compatible regarding files, so I still intend to share those.

That's about it for this update, I hope to see some suggestions!
