Early morning information system

When we open our bleery eyes first thing in the morning, we've not had chance to process our surroundings yet. The first thing we see is our alarm clock and from it, we get out first vital bit of information: have we got time to back to sleep? However, our alarm clock could help us prepare for the day a little more. Lenka Designs have improved an old alarm clock to give you more information. We asked them about this, and here's what they had to say:
"We are three people – Elena, Eugene, and Alex – and we run a small design workshop. It’s the hobby part of our life while we do day-to-day, normal jobs. Each one specialises in a different area – Elena in design, Eugene in mechanical stuff (making things), and Alex in programming. The things we have done in the past range from interior design to small microcontroller devices.
"The clock that we made is nothing special technologically, except that it was made from a salvaged clock and a salvaged phone battery, which most people would just dispose of. About one and a half years ago, I discovered the world of microcontrollers. It is fascinating how the Arduino team have made it so easy for people to start with MC devices. I saw others making devices on YouTube using Arduino, and some temp/pressure sensors, and so decided to have a go at it. So, this was my first Arduino project. Since it was my first device, the best I could code was the clock and display icons with meter readings. Settings, alarm, forecast, etc. were all programmed in V2 by Alex, and now the code is quite sophisticated.
"Overall, the electronics setup is simple – we used modules and connected them all together: a salvaged Nokia 5110 LCD module for display, a BME280 module for weather, a DS1307 module for real-time clock, TP4056/5 V boost modules for power, a buzzer that was salvaged from the old PC, and the basic LDR module. The faceplate is recycled, and the original bells were preserved – we connected the motor to Arduino through the transistor.

Make a Smart Home in Raspberry Pi Official Magazine issue 167
The dream of smart, connected devices controlling your home automatically, is especialy appealing on a lazy day when we’re trying to get work done in a heatwave. Maybe this will be the year we finally integrate temperature sensors with fans and a drinks dispenser to keep us cool, or maybe not, but we do know […]
