Android app for SHAC

I entered the latest version of SHAC, our smartphone based access control system to MOMO and was selected as finalist!The latest version uses a low end Android device as the back-end instead of the SLUG and comms is using XMPP, so can go through 3G or Wifi.

I get a two minute spot to talk – please come and support me.

Autonomous robot using Arduino 9D inertial sensor


Hey keep up the good work guys!  My first visit to the H4H yesterday was great fun and I am really impressed with this initiative – its a haven for hackers and makers and reminds me a lot of the Ham Radio clubs I used to visit with my dad many years ago.

Btw see this link for a weaponised robot I made (during my dayjob nogal – a lunchtime project I should add) that uses the Arduino based Razor inertial measurement device.  Thanks goes to Mathew at Cogency who greatly improved the precision of the inertial feedback by implementing some filtering on the processor.

From project to product – Part 1 – Soldering : Course 26 November


We are planning a soldering course for this Saturday 26 November.

Nick Michael will present this course and will cover

  • basic soldering theory
  • soldering secrets
  • application – an Arduino Prototyping mini-shield
  • how to turn an el-cheapo soldering iron into a professional iron !!!

Please bring you own soldering iron – we will supply the rest, including vera board, solder wire etc.

You will go away with an Arduino Prototyping mini-shield that you can use to turn a project into a product 🙂

We will start at 9 and the course fee will be R150 including lunch.

Please let me know if you are interested – the class will be limited to 6 people.


I’ve received confirmations from:

  • Philip
  • Ant
  • Mike
  • Jossekin
  • Marius
  • Devin

That means all six spots are taken.  We will schedule a similar course soon.
