What happened Tuesday 22/10


Schalk was doing some soldering to get a serial connection to his quad’s radio so he could flash it. A question arose “why?”
the answer might be in here.. i left before 12, and Quentin and Gert was still assisting.

Nic rocked up with his board- see a post from Peter- simplicity.. i can rather see myself build a board like that.


And Hans came around.
And as per normal brought stuff with. – as i showed Peter

RHoK Pretoria June 2013


Random Hacks of Kindness was this weekend, 1-2 June at UNISA, organized by UNISA Pro-Bono Computing (Jabu), CSIR (Ishmael) and House4Hack – although Jabu did most of the heavy lifting as usual.

The event was attended by 40+ enthusiastic and dedicated Rhoksters and 8 of these worked all night Saturday evening!

House4Hack and TUT (Tshwane University of Technology) again collaborated (previously at the Nasa hackathon)  and this time won!

Winning team - Hey Go There

Our team had the following members:

  • Shawn (Peace Corp)
  • Raoul (TUT)
  • Khuthadzo (TUT)
  • Gabriel (TUT)
  • Guy (H4H)
  • Schalk (H4H)

Gabriel, Schalk, Khuthadzo, Rauol, Guy and Shawn

We tackled a problem posed by Shawn Joshi from the Peace Corp and the following Prezi by Shawn explains the problem and the solution we built:

As a nice touch we added a Augmented Reality view to the solution and here is a video of Guy checking out the view and discovering where to go and where not to go:

We still have lots of work on this and hope to get it to a working product soon – if anyone is interested, the source code is here:

Well done to everyone who participated and helped to make this the best RHoK yet!
