…jumps over the lazy dog!
There is one part of the HMI system I did in a somewhat “lazy” way. I’m creating display objects (JFrames, charts) in memory for each of the display elements. While this ends up being a nice tradeoff between memory and speed (changing between elements is near-instantaneous), I should probably reduce the memory footprint of the […]

In your home, when you touch a button, you expect the associated lamp to light immediately. For example, if you open the door to your basement, you need light right now to go down the stairs safely. Waiting a couple of seconds for the lamp to light is not expected, nor desirable. After all, the […]

The network of nodes is working perfectely, lighting and blinds control is 100% done in terms of logic (I still need to prettify these elements visually), as are the temperature sensors. […]

Ora eu preciso de sensores com […]

I designed my new central heating system in the most flexible way: it basically has heat generators, heat consumers, and a heat store. It has a hot water cylinder, used as the store; the generators are 6 solar panels (thermal, not photovoltaic), and a wood-based water boiler (the livingroom fireplace); the consumers are the hidraulic […]
