Occasionally you may find that a notable Twitter profile may remove tweets, or be shut down before preservation can be initiated by the forensic examiner. Should this be the case, you may be required to refer to caching services such as Google Cache or Twicsy for example. I recently had need to evidence data found on Twicsy, however the web interface isn't exactly forensic friendly when it comes to how it displays the data. Twicsy.com is a Twitter picture search engine, which appears to duplicate the original textual data from a tweet containing an image, and stores this information on their own web server. The image from a tweet is simply referred to from the source, and if the tweet is deleted or the profile removed, you'll find the image won't exist any more. However the textual data does still remains on Twicsy's website despite the original tweet not existing. After discovering this I wrote a ruby script to extract each of the archived tweets and place it into a format which is readable.

As anyone who has used the Arduino IDE over time will tell you, this crappy piece of software has barely changed since the Arduino first surfaced. It has no autocompletion, […]

In October last year, I got the opportunity to build a RepRap Huxley pro 3D printer for a community crafts centre based in Ashford, Kent. The craft centre wanted a means to demonstrate to its hub of artists how to incorporate new technologies such as 3D printing into their studio work, to create never before seen creations. By building the Huxley it provided me the confidence to build my own 3D printer, which in a series of posts I'm going to discuss further.

I was sent a link to to the following great article on power saving techniques for microprocessors and in particular the ATMEga328P which is the chip used in the Arduino. […]

It would seem that everyone and their dog are getting their own Quadcopter or quadrotor (often misreported in the media as a drone, but that’s another story). A recent build day ran by Reading Hackspace allowed me to jump into their … Continue reading →
