Last week I designed a small development board for PIC18F45K50. Goal was to design a small PCB for TQFP package to give away to students and teach them how to solder and how to use this nice microcontroller from Microchip. After a while, board came back from the fabrication house and they look and works great. 🙂

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!

This weekend I have found some RGB LED strip laying around so I decided to build custom RGB LED strip to decorate my room. The RGB controller that I’ve built is based on Microchips PIC16F1455 microcontroller. It works as ambient light in my room and also there is an option to use it as mood light (randomly change colors every…

I just finished working on a remote controlled, color changing cloud. Cloud can change colors to please your mood, for example there are presets like cloudy day, rain, storm, sandstorm or it can be used to notify you when you have received an email, message on facebook/twitter or any other social media event. Also it can be used to detect…
Leave a CommentI 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…
1 CommentDo you care about your security? Security of your online accounts? Your Facebook account, GMail account, Twitter account and others… What would you do if you lost them because your password wasn’t too good to protect them. I have created Random Password Generator that allows you to create passwords that are complex and good enough to ensure that your account…

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)
While drinking my morning coffee I’ve red the article about the meaning of unique 13 numbers that people from former Yugoslavia have as their unique citizen identification number (called JMBG). I bet that more than 95% of people know what the first 6 numbers of their JMBG mean, but the other 7 numbers remain the mystery for most of them.…
