Increasing Your Browsing/Download and Utorrent Download speed

Simple steps to enhance (increase) your download speed.

1. Enhancing your broadband speed - enable DMZ Host.

  • Go to
  • Click Advanced Setup -> DMZ Host
  • Enter the IP addres you have entered in ur LAN settings
    ( Network and Sharing Center -> Local Area connection -> Properties -> select Internet Protocol version 4 and click properties. Note the IP Address entered here)
  • Enter this IP Address in the space provided.
  • Click Save/Apply
Caution- Enabling DMZ Host results in packets of data constantly being sent to and fro, so make sure you disable it once you have finished your downloading.

2. Enhancing (increasing) Utorrent Download Speed.

If you have a BSNL unlimited plan like BB Home UL 750 then note that the following steps wont have a miraculous effect on your D/L speed (unlimited usage comes at a price, unfortunately here it is speed), however you may find it does help in your downloading.

Go To Preferences

  1. Select Bandwidth -> Number of Connections
    Global Maximum number of connections -> Enter a large value ( >10000)
    Maximum number of connected peers   -> Enter a large value ( >100)

  2. Select BitTorrent - > Protocol Encryption -> Enabled -> Outgoing
    Check the option Allow Incoming Legacy Connections.

  3. Under BitTorrent - > Protocol Encryption.
    Check Enable DHT Network if it is not already enabled.

  4. Under Connection ->
    Check Enable UPnp Port Mapping.
    Check Add Windows Firewall Exception.

  5. Adding Extra Trackers for  your torrent always helps.

Alternatively you can try using other DNS servers ( but this is more for Browsing than for Downloading)

Go To
  •  Network and Sharing Center -> Local Area connection -> Properties -> select Internet Protocol version 4 and click properties. 
Change the values as follows

  1. Google Public DNS Servers
  • Preferred DNS Server:
  • Alternate DNS Server:
  2. OpenDNS free DNS Servers
  • Preferred DNS Server:
  • Alternate DNS Server:
  3. Norton free DNS Servers
  • Preferred DNS Server:
  • Alternate DNS Server:
(to name a few)

TI eZ430 Chronos - 'watch' this space!

For a long time, I had been waiting for the watch I now own - the eZ430 Chronos. As the TI wiki says,
The eZ430-Chronos is a highly integrated, wearable wireless development system that comes in a sports watch. It may be used as a reference platform for watch systems, a personal display for personal area networks, as a wireless sensor node for remote data collection, or simply as a watch.
I love interfacing things with my computer and wanted to experiment with accelerometers. When I first looked at this watch, I knew it was best suited for a person like me. Here's what they provide in the box...
  • Chronos wireless watch
  • CC1111 USB RF access point
  • USB Programming and debugging interface
  • 2 spare screws 
  • Mini Phillips screwdriver
  • CD containing documentation and development software

The watch itself contains sensors like
  • 3 Axis Accelerometer
  • Pressure sensor
  • Temperature sensor
  • Battery/Voltage sensor

So I figured, I could use the accelerometer and say "Look Ma, No Wires!" & have no hassles of a breakout board or anything for an Arduino(or any microcontroller for that matter). Being in a wearable form factor, I could also interpret gestures from hand movements, use the watch while trekking, be the one to answer correctly whenever someone would be estimating the temperature... and what not!? Oh did I state that you get all the stuff mentioned above for just $49. I finally ordered the 433MHz version and I have to say, this watch is pretty interesting!

It is based on the CC430 ultra-low-power microcontroller system-on-chip with integrated RF transceiver which can be programmed via the eZ430 USB programming and debugging interface. Sample codes and other stuff is available online. But what I first wanna try is getting the accelerometer values on to my laptop and make a wii-style controller for games like Need For Speed. Wouldn't that be cool? Just wear the watch and 'drive' the car using a vinyl record, just to get the feel of something like a steering.
