DIY Wake-up Light – Wake-up easily and well rested

Published 31. December 2016.

Theory behind this project

Another weekend project that I’ve been working on is Wake-up light. Lately I’ve been doing more research on sleep phases and how to “hack” your brain to wake-up more refreshed and adjust your sleep cycle. There are many studies out there explaining this and providing scientific evidence, so if this is something you are interested in, I encourage you to go and get more detailed information on this subject. However I won’t go into too much detail, I’ll just try to give very simple explanation: When you sleep, you are either in REM or deep sleep (NREM) phase. When you wake up in REM phase you feel fresh, relaxed and full of energy. When you are woken up during the deep sleep phase, you feel like you’ve just been hit by a bus, and you take long time to actually wake up.

New project – Sensor board for smart home

Published 23. January 2016.

These PCB-s are a part of much bigger project that I am currently working on and I have been waiting for them waaaay too long. Boards are designed to house two I2C sensors, (almost any I2C sensor breakout board can fit onto dedicated headers), at the moment I am using Temperature+Humidity sensors, Pressure Sensors, Ambient Light sensors and few others on these boards. Also I am using PIC16F1829 microcontroller to do all the “magic” and nRF24L01+ for communication with the main unit that does storage, data analysis and communication with other parts of the project.

Mini project: Heartbeat Keychain

Published 12. February 2015.

 

Heartbeat key-chain is intended to be a small gift that your loved one can carry with her/him wherever she/he goes.
Basically top side of the PCB is touch sensitive and has one RGB LED. When the exposed copper on the top side is touched, the microcontroller detects it and begins to pulse the LED in the heartbeat like pattern.

Bill of material, schematics and source code are available on GitHub.

I am posting render images of the PCB since I’m waiting for the Fab house to manufacture the boards for me.

Build Small Bedroom Clock from scratch in under 4hours

Build Small Bedroom Clock from scratch in under 4hours

Published 12. July 2014.

First, maybe you should see a little demo on YouTube to see how this thing looks in action…

Before we start…

I wanted to make this project for myself, and since this is very simple project, I placed a challenge to complete it in shortest time possible and make it work as I intended to.
From idea to finished product it took about 4-5 hours, including designing schematic, routing PCB and making it, programming the device and etc.
What is important is that finished product works like I want it to do, and it could be used as opportunity to learn something about other platforms different from some that are spamming us 24/7 like Arduino.
Don’t get me wrong, Arduino is great and all but sometimes I want to build something for myself from scratch. 🙂

One thing I want to ask you all is to share your opinion, how to make this project better, what would you add/remove, did you use it? Did you like it? Did you make/modify it? Share it with us!
