Touch gesture recognition using body capacitance

For my final year project, I tried to replicate and possibly improve the Disney's touche device using much cheaper components than they did. It was a partial success, but a great learning experience nontheless. These days most touch sensitive devices are designed either to recognize where it has been touched or whether is touched or not. Many objects around us in everyday life can be potentially used as touch interactive surface providing they are made out of conductive material. With the conventional way it would only be possible to detect whether the object has been touched or not. However, by exciting the object with different frequencies it is possible to detect how much skin is touching it. Essentially the system could recognize whether the object is grabbed, pinched, touched by one or more fingers or any other gesture which have different amount of skin touching it. There are many surfaces, objects and liquids which can be transformed into touch sensitive devices without additional buttons or touchscreens like door handles, mobile phones, lamps, desks, walls etc.

QHotkey is simple application for changing the MS Windows volume with your prefered keys. Also it will show nice popup with the current level of volume.

Basically, I had problems with my laptops hotkey application, it has a very long response time which renders the volume keys and all the other function keys unusable. So I decided to make QHotkey, so at least I can change volume as quick as possible. There were already some solutions available, but I found them either not looking as good as I want to or lacking key customization.

Pigaso - SVG to gcode coverter

For about a month I've been working on a SVG parser, which translates the SVG primitves to gcode, for the use with 3d printer. I started developing the Pigaso so I can easly plot PCBs with my 3D printer. Unfortunately for me, there wasn't any application, which would easily enable me to generate gcode from SVG image, or any image in that matter. So I though of making my own application to do just that. My main goal, is to develop a converted which is easy to use, and specialized for generating gcode, no hacking required. Continue reading for a demonstration.

DIY 3D printer, AKA RepRap

Parallel to my work, I always do some kind of project every summer. Last summer was a game, which I didn’t manage to finish (got lazy on designing the levels). However, this summer I took on to a journey in a field I have almost no experience. Basically, I built my own 3D printer. Without any kits, I wanted to take away from this journey as much as I could.  I’ll try to remember all I did, and write as detailed as possible about this journey.  In any case, I would advise anyone to try and do this project, it’s a very good learning experience, but be warned that it isn’t a walk in a park, like I thought. When I started this project, I though it wouldn’t take more than 2 weeks to finish it. Well if you know what you are doing, probably it would take less than one day to assemble it, but I didn’t.

Simple TLS/SSL SMTP client for Qt5

For one of my projects I wanted to develop a crash reporting dialog where user can enter the steps he did to crash the application and then by pressing send button the app automatically will send me user report and the log to my e-mail address. Unfortunatelly Qt doesn't have a Smtp library, and I don't want anything heavy just to send a simple string of characters through gmail smtp server.
