Remote Colorful Cloud

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 temperature, humidity in the room and based on that to change color (eg. blue = cold, yellow = warm, red = hot).
There are numerous options to customize this cloud. I would like to hear from you what would you like to see in this finished product when it’s released.
We’ve posted few pictures of our cloud below, more updates will follow as the project develops.

Random Password Generator

Do 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 are protected from unwanted access and possible hacking. Please read the guidelines for good password creation and make sure your passwords are complex enough. If you can’t remember them, write them down and after you have used them for a few times you will be able to remember them just like you remember your current passwords. Password generator randomly selects letters, numbers and other symbols to generate completely random password that is generated only for you and no one else. There is no way to restore previously generated list so if you like any of the passwords that have been generated, write them down or they will be lost forever.

If you enjoy this application, share it. Also if you see any room for improvements, let me know.

Simple Stereo LED Light Show

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)

Application is very simple and plain to use, on start it asks you to pick a public transportation line that you would like to use, after that, another screen appears where you can see the time schedule for work days, Saturdays and Sundays.

PlusPon – Daily deal aggregator

The idea behind PlusPon project is that you don’t have to visit hundreds of daily deal sites just to find what you are looking for, instead you can visit that lets you search thousands of daily deal sites at once and lets you filter offers by region, category, price or any other way you want. All deals are displayed on the map where you can see how far from you they are, how long will they last and how much discount you get and ofcourse, option to buy that deal. The project is still in beta phase but you can take a peek at our Test Server to see the idea how it’s going to work when it’s done. If you have questions about the project please feel free to contact me or leave a comment.
