Jossekin played with the kinect last night and scanned his hand into an STL
The rapman uses skeinforge to convert stl files into gcode for printing on the 3d printer OR we can use pycam to convert it into gcode for the CNC router 
To check out the hand in stl format, you will need meshlab or similar and you can download the file here:
Nick will be presenting Basic Electronics this Saturday 25 Feb 9-13

* Introduction to semiconductors
* # different technologies for Switching power to a load/motor
* Relay Circuit
* Transistor Switch : Common Emitter
* SCR Switch
* Transistor Current Amplifiers
* NPN Common Collector
* PNP common Collector
* NPN Common Emitter
* NPN/NPN Darlington pair
* NPN/PNP Darlington Pair
* Practical LABs for the above
You will need an Arduino and breadboard for this course.
The course fee is – R300 (components provided worth R100)
Please send a mail to schalk dot heunis at gmail dot com
Watch this space….
Marcus and William cut some hearts and flowers on the CNC machine and since it is Valentine’s day, Toby and I added some music
The video shows the CNC routing in 12mm super wood.
So hope you had an awesome Valentine!

We are planning a soldering course for this Saturday 18 February:
The course contents as follows
The course fee is R200 and this includes pizza for lunch. The course starts at 9 and should be finished by lunch time. Solder and components will be provided, but bring your own soldering iron.
If you are interested in attending, please mail me at schalk dot heunis at gmail dot com
Toby Kurien will be presenting an introduction to Android this Saturday 11 February from 9 – 14. Toby is a well known Android Freelancer and publishes on amongst other, Toby’s Dev at AndroidZA ( http://www.androidza.co.za/category/tobys-dev/)
During the course you will build a fully working Twitter Application! Using the knowledge gained from the course, I wrote (hacked together) the Galaxy Tab-winning SHAC app So you do not want to miss this one!!!
GTUG is planning an Android Hackathon the weekend of the 18th (details to be finalised) and this course was planned to coincide with that event.
Course fees are R350 and include snacks and lunch (pizza). You will need a laptop and working knowledge of java (or C# at a stretch)- please pre-load eclipse with the android sdk – Toby will publish a step-by-step later the week OR come on Tuesday evening and we can help you install all the bits.
We only have 10 spots available and 3 has already been taken. To confirm your attendance, please mail me at schalk dot heunis at gmail dot com
 Android back-end for SHAC |
 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.

To see a mind blowing 30 seconds video clip of the app in action:
ok, open shot video editor sucks (I blame it on the video editor) Will make a nicer version for Monday
Below the mail from MOMO
Hey Schalk,We are happy to inform you that you are a finalist for the MOMO App competition.Please confirm by the end of today if you are able to attend the event..Please take note of the following:- Please be at the venue at 17h30pm. If this is an issue, please let me know before 12noon on Monday- Please bring all pitch presentations in PowerPoint format.- Please be ready to do a live demo if required- You have 2 minutes exactly to wow the audience, no more or no less.- If you have a video, please send through the youtube link ASAPCongratulations.
We are planning an Arduino Introduction Course this Saturday 28 January from 9 to 13.

Yesterday saw the arrival of a monster sized CNC at House4Hack
The machine is part of a venture being incubated by Marcus, Dries and William. Dries was responsible for building the machine and the group are planning to explore a variety of products and services using this very impressive piece of hardware.
The machine is fitted with a router and can be applied to wood and most plastics. The table is about the size of a table tennis table and can easily be applied to a full sized door!
One of the reasons for incubating at House4Hack is the potential for cross-pollination between mechanical, electronics and software – the collaborative intelligence that are possible are mind-blowing, think UAV’s, Solar Cars etc, etc.
Currently the plan is to have demonstration of the machine coming Tuesday evening.
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.
