USB Battery Pack

After watching Systm Episode 86, I decided to build the second version of the USB Battery Pack. This is, as David has pointed out, not the best way of charging a USB device, as it simply relies on a 7805 Voltage Regulator. But I had one lying around, so I decided to go with this version.

I used an altoids-maxi-tin, which left me with enough space to fit an iPod cable in as well.

HDD coaster

There are many things you can do with a dead hard drive. A stylish coaster is one of them:

Use some double-faced adhesive tape to hold the individual platters in place – that’s it.

PortProbe

Just did this for an assignment in school. The objective was to create a simple GUI for scanning common ports on any IP and report on their status. I went for the overkill and implemented more features and a multithreading GUI for progress analytics.
So have a look at PortProbe.

Features include:

  • Common ports scanning
  • Range scanning
  • Validity checking (IP and Ports)
  • Name resolving
  • Verbose output
  • Progressbar
  • Full HTML output (new)
  • Cancel running scan (new)
