I purchased a Steel Portable Firepit to try and make a fire with pretty coloured flames using Mystical Fire x 3 Sachets. It worked, but didn’t completely change the flames, I think because the firepit was quite large. I plan to try again but using more sachets in order to compeltely change the colour of the flame
Following Google’s announcement of Material Design I released an update to PortDroid with a redesign with lots of improvements.
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.
- 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
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.
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.
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.

- 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
Comparison to the digimicro
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:
And the second (maximum zoom):
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.
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
