F.lux or no F.lux and Linux!

I’ve been using a program called F.lux or Flux for over a year now.

The program is based on the research that blue light keeps you awake and alert. Not something that you’d want at night. So this program adapts the display to show warmer colors at night. You can read more about the program on it’s website. Normally flux adapts the colors as the day progresses and night starts but I preferred to keep the colors warm (yellow-ish) all day long. It’s really easy on eyes even for those long hours spent staring at computer screen.

However Flux for linux lacks the features that it’s Windows version offers. Most particularly the options of controlling the color phase during the day time. Also getting it to work on a dual monitor setup was more effort than I intended to spend. So I decided to fore go the program altogether in favor of changing the color profile of the monitor itself.

Most monitors have the color settings that allow you to pick the RGB (Red Green Blue) levels in your monitor. I fiddled around with mine and set the levels of R-100, G-100, B-0. Hence getting the blue component out of the display and achieving the same effect as flux.

Try it out yourself and see if you can adjust to it. I’d suggest using the default settings of flux till you stop noticing the yellow color of the monitor and then moving to yellow color altogether. I’d recommend giving it two weeks of usage before making a decision on if you want to stop using it or not since it feels odd initially and it takes a bit to get used to.

Let us know if it worked out for you!

Installing transmission and dnsmasq on a NAS

Introduction

In our student’s  dorm, we want to share files. We also have one shared internet connection using ADSL. The download speed is OK, but the uplink is weak. Many students like to use torrents, which quickly drain the uplink and the connection table of the modemrouter. So I set up a server with a torrent client, which was accessible by a web interface. I replaced this server by a Iomega StorCenter Ix2-200 Cloud Edition Network Attached Storage (NAS) device, which I will refer to as ix-2.

The default torrent client on the ix-2 is bad beyond imagination, so I wanted to install transmission-daemon. Read the rest of this entry »

Testing rechargable batteries

Author: Bob Westerbrink

Rechargeable batteries aged 6 years or older are, in general, garbage (this also is true for most car batteries). How good are your rechargeable batteries? You can test your batteries by measuring the time it takes until they are empty while they power a LED or something similar with a small resistance. It’s easiest to use a resistor.

Instagram – Using the API

First a short introduction on Instagram, it is an iphone app for taking pictures, adding filters to make them look retro, and then for sharing them with sites like Twitter, Flickr, Tumblr, and Facebook, more importantly, it’s a simple social network of other people’s photos. You can “like” or comment on the photos, and see what’s new. It’s easy and doesn’t take much time or effort. This is one of the reasons it has become so popular so quickly.


What is also good to know is that Instagram has recently released an API which the user’s can use to fetch pictures that users upload to the website. In this article I want to discuss that API and how to use it to make the most out of it.

How-to: Turn Your Cellphone into a Microscope!

Being the enthusiast I am with shooting photos and making videos, I also enjoy taking it to further levels. Earlier we posted a super simple how-to tutorial (here) on adding the macro functionality to your cellphone (while keeping it low-budget). In this post, we inform you of how to turn your cellphone into a small portable microscope (while still keeping it low-budget).

  1. If you haven’t gone to Crabfu’s page who made this mod, go there.
  2. Find a low-budget (~10 Euros) microscope lens of your desire (either online or from a shop you know) that matches the specs Crabfu has mentioned (mainly it should fit to the cellphone lens or it’s case dimension).
  3. Wrap the cellphone case in a plastic bag.
  4. Put your cellphone in it.
  5. Glue the lens connection and very very carefully put it where the phone lens is supposed to be.
  6. Attach the lens to the connection.
  7. Done.

Enjoy using your portable microscope while helping people icon smile How to: Turn Your Cellphone into a Microscope!
