This blog post will cover the build process for Aurora up, if you want to find out about how it was built you can read about it here, If you'd like to look at the code you can see the github It's o...

Many years ago someone told me this interesting fact about how people receive compliments and it went something like this: "If a person receives a compliment, even if they know it is disingenuous,...

Over the years, halloween has always been fun for me, I basically wish I was American so that I could dress up excessively every year! This year I decided that I would like to build my own costume....

Usually I have a blog post about building/breaking something with the intention of actually building or breaking it. This one however is not like the others. It started about 2 years ago, I got a P...

Defcon every year has many many different electronic badges that you can play with / hack / blind your friends with. I was lucky enough to get one of these really cool badges and I wanted to figure...

After the fairly successful ZACon badges I did in 2014 , the BSides team in Cape Town (where I now live) asked if I'd like to be involved in building another one. Naturally my response was abso-fsc...

Recently, I've seen a number of posts on Facebook groups for South African communities about people having their car remotes jammed and the contents of their cars cleaned out while they are at petr...

Badges At some time in the next 6 billion years I will complete the writeup for the badges about how they were put together. For now this is just how to get your badge working at home as well as ho...

This blog post will discuss the implementation of Codegrabbing / RollJam, just one method of attacking AM/OOK systems that implement rolling codes (such as keeloq) -- these systems are commonly fou...

The ZaCon badges were a ton of work on the hardware side (see ZaCon V Badge [1/2]: Build Time ), however they provided their own challenges on the software side as well. Since my knowledge of chips...

I realise I should have done this entry a little sooner, but as everyone should be well aware of by now, I am lazy. Also I moved to Cape Town just after ZaCon V which proved rather time consuming!...

UPDATE: For those people that missed the friday night the code and slides are here: Slides: /Badger Badger Badger.pptx Code: https://github.com/AndrewMohawk/zaconv/ MAGICELECTRONICBADGES Ever since...

I really should have written this after ZaCon (november last year), but I'm lazy. However I have been asked to give a brief overview of the same talk at ITWeb this year so I figure I may as well fi...

This is just an update on the Arduino watering system, everything seems to be going well whilst I am away (I am away for ~a month, till the end of Blackhat / Defcon). In winter the plants don't req...

Intro So its been nearly a month since I last put a blog post up and I have been working on some stuff in my free time between work (been traveling to the US and took a weekend off to visit some fr...

So this is going to be a rather strange post as at the time of writing its not actually implemented, the system is built in a waterproof container as well as the networking setup and so on. I figur...

I've always been harping on about growing my own tomatoes and other veggies and earlier this year i attempted it for a while.Unfortunately with me going away for various conferences and generally b...

zacon - http://www.zacon.org.za/ - is just around the corner now, so badge submission went out. Wasn't particularly inspired but i hacked together 3 diff ones, now we just wait and see. UPDATE Deci...

So its been ages since i last blogged, and i am determined to try do this more regularly since it will probably get me onto doing more stuff! This is pretty much the first thing i built with the Ar...

So i've commented most of the lines and you should be able to easily follow what has happened in the code. Leave a comment if there are any questions :) Code after the break!

So i see its been forever since i have posted anything, figured its about time, and i wanted to show some of the stuff ive done with my Arduino . The first thing i tried to do with it was create my...

So i figured i'd drop a quick update on what i've been messing around with, firstly ZACon II was awesome! I'm really dissapointed i didn't submit a better talk and get a chance again, however i did...
