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.

BinHexDec Convertor

Published 6. December 2012.

I needed a simple calculator/convertor to convert between Binary Decimal and Hexadecimal number system. I’ve created a very simple convertor in VB.net and I’m sharing it with you in case someone gets in the same spot as I was few hours ago 🙂 [FEATURES] Some features that might come in handy: 1. Double click on empty space to toggle window…

Simple Stereo LED Light Show

Simple Stereo LED Light Show

Published 19. March 2012.

This is the Light Show made from LEDs and few discrete components like resistors and transistors. It transforms audio signal into light signal with LEDs. We have used two types of LEDs, white and blue, each one for different sound channel (from stereo audio output).

Our prototype was first built on solder-less breadboard. Link to YouTube video

Components that are required for this build:
– 5 VDC regulated power supply (You can use your USB cabel)
– 2 NPN transistors (any transistors will work, we have used BC547 for our prototype) (for one channel)
– 1x300K resistor and 1x33K resistor (for one channel)

JGSP Novi Sad – Red Voznje v2.1

Published 2. June 2011.

JGSP Novi Sad - Red VoznjeJGSP Novi Sad – Red Voznje i new and improved version of mini-program that fetches data from official JGSP Novi Sad site and show you only the relevant data about the Bus Line you have selected from the menu. Now program can remember what was the last line you have selected and on next start-up it automatically loads it.
You can keep this program in your Systray and when you need to find out when the next bus is leaving your station you just double-click the icon in you system-tray and the program will pop-up back.
This program is very tiny and has very low resources consumption (updates data every half hour and has no background processes) so you don’t have to worry about eating your resources or your internet bandwidth.

If you want to request a feature or have a suggestion please feel free to email it to me and I will make it in the next release.
