Teasmade is an open source challenge by VEEB on GitHub that supplies a terrific instance of “upcycling” – the respiration of discarded or even broken merchandise with your programming and electronics competencies.
I firmly feel in the ‘make and fix’ principle – as an alternative of just throwing a rather contemporary fridge / freezer away simply because its electronics failed, it was an interesting problem to convert it into a sensible refrigerator that I could handle remotely a “substitute” Raspberry Pi. Since I did, it was an emergency response – act fast or the contents of the freezer would will need to be thrown absent – there is no label on this particular challenge.
Given that it uses a Pi Zero, the Teasmade challenge was a short while ago described on the Raspberry Pi web site and there is a online video exhibiting the job:
The hardware for everyone who wishes to mimic the strategy starts with a absolutely practical teasmade, effectively a kettle combined with an alarm clock that was at the height of decadence in the 1970s. To enhance for your new function, you need a Raspberry Pi with a relay swap and an online connection. The latter is required so that the unit can be managed by means of Google Calendar. This is performed with gcalcli, the Goolge Calendar Command Line Interface, which is also readily available on Github underneath an MIT license. The Python script that brings the overall challenge alongside one another has a GPL 3. license. In accordance to its GitHub README, the moral of this job is:
It is doable to use home automation controls devoid of logging in so that a listening product is always related to the cloud.
Google Calendar would seem like an outstanding way to go if you want the adaptability to plan an celebration, but what if you are dealing with events that are activated by exterior circumstances? For instance, you can use a heating mat to maintain some thing inside a certain temperature range. In this situation, no online link is needed and you can think about a Pico, the latest, smallest and most affordable member of the Rasberry Pi family. This is not essentially a Pi as it is centered on a personalized chip formulated by the Raspberry Pi Basis and is far more conveniently offered than the ARM-dependent Rasberry Pi Zero machine. The benefit of provides is that it is not topic to the rationing of a single product per obtain that is however plaguing the Pi Zero. And if you want wireless cabling that the Pico won’t support, I’ve outlined a rather affordable way to include it in my publications. Programming the Raspberry Pi Pico in MicroPython and Programming the Raspberry Pi Pico in C.
