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. 🙂2 Comments
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!Leave a Comment
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…Leave a Comment
Hard & Soft is a contest for senior students of Computer Hardware and Software Engineering who will work on an unseen task over a period of five days in teams of four. Contestant Knowledge Requirements The Hard and Soft contest has a focus on topics that require a close link between hardware and software in computers and ICT, to be…Leave a Comment
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 Comment
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)
