PortDroid – Portscanner networking tool for android relased

Feb 17 14

I’ve always enjoyed playing about with network security tools, so I decided to write an android application that merges a few of the most useful network security tools.


PortDroid on Google Play

Features

  • Local Network – Find devices on the same network
  • Port Scanner – Search for open ports on a device
  • Ping – Check the response time from a device local or remote
  • Traceroute – Trace a route between your device and a given host
  • Settings – tonnes of settings for all the tools
  • Advanced browsing of /proc and /proc/net for device network information

Getting bitcoins in the UK

So getting bitcoins in the UK has been quite difficult ever since blockchain.info stopped allowing Barclays ping-it transfers. This was a really convenient method of obtaining bitcoins and the alternatives are going through multiple websites and or countries and therefore losing additional money in the transfer.

Blockchain.info stops all UK Deposits

However I’ve found a website that hooks up local people looking to buy with those looking to sell for a small transaction free localbitcoins.com. You can meetup face-to-face or do bank transfers etc online and use their escrow system to avoid getting conned.

Just a quick post to mention how much I am enjoying using a dock for my phone. It only cost ~$19 avaliable on dealextreme, it comes with a EU plug (US version avaliable too) but I’m just using it via usb.

What’s that awesome live wallpaper? It’s the latest beta of nexus revamped! This dock has been really useful for development of this livewallpaper, so handy/convenient.

Fun with LED’s and liquid nitrogen

Working in a physics department has it’s perks. Below shows an orange LED changing colour as it is submerged into liquid nitrogen.

Many thanks to my house-mate for letting me play with liquid nitrogen and try this out.

Photos with my new usb microscope (20X-400X 1.3MP Digital Microscope)

I have been quite pleased with my previous microscope but I decided to buy a slightly better one from dealextreme as double the magnification was available for only a slightly higher cost.

product link) It only cost $48.20 USD (about £31.27 GBP) only $8 than my previous microscope that could only achieve 200x!

Quick Review
Advantages

  • Large dynamic zoom range (labelled 20x – 400x)
  • Easy to setup (plug and play)
  • Can take some awesome photos, see below
  • Variable illumination settings (using a wheel at top)
  • Rubberised casing gives better grip and good overall feel
  • Much improved build quality over the digimicro
  • Stand is sturdy and can hold camera still in place

Magnification measurement
The images are taken with the edge of the camera case pressed right up against the ruler. You could probably remove casing to increase zoom slightly, or create a slot to slide a microscope slide into it. The camera has two focuses the first:

First focal point of microscope

And the second (maximum zoom):

Second focal point of microscope (0.5mm spacing between lines)

Second focal point of microscope (0.5mm spacing between lines)

6mm displayed over 170mm: zoom ~ 30x
0.5mm displayed over 180mm: zoom ~ 360x

This isn’t far off the specified 20x – 400x so I am happy! (Note: Measuring magnification level is rubbish as it depends on screen the image is viewed on, so viewing it on a projector would make the statistics seem more impressive.)

The minimum zoom is less than this as we can move the camera further from the object

Setup in Linux

The beauty of this webcam is that it requires no installation with ubuntu 10.04 you simply need to run the software and the camera works! woo! The output of `lsusb` shows the device as:

Bus 001 Device 004: ID 0ac8:3610 Z-Star Microelectronics Corp.

Software
Most video programs will pick up the device, I am opting to use a program called cheese which is awesome not only because of the name but also because of its simplicity.

sudo apt-get install cheese

As before any requests for microscope images (within reason) will be considered :)

Borderlands hidden QR codes

I found an easter egg in borderlands:

Borderlands hidden QR codes

zoomed in on the qr code

So I used a barcode reader on my Nexus One

Plaintext:

NICK WILSON

HO OH

However I am not the only person to have spotted this, unsurprisingly really as I’m almost half a year late on starting the game. There are several QR codes hidden as shown in this wiki page and someone else went to the pain-staking task of copying out this QR code pixel-by-pixel rather than using a QR scanner or image software, crazy!
