3d-printer update – it’s alive


Jossekin (mostly) and I continued the 3d printer build and managed to get to the point where we manually control the x,y and z axis.  Marius helped me to shoot a short video using my phone – so apologies in advance for the quality 🙂

Basic Electronics Course – Saturday 10 December


Due to popular demand :-), we are planning to have the Basic Electronics Course this Saturday the 10th.

Nick will be presenting this course and as per his mail will cover
1. transistor ac & dc amplifiers Emitter followers , darlington pairs , inverters
2. Op-Amps (741 / 747s)
3. D/A converter using OP/amps , Hi Pass and Low Pass filters
4. 555 timers
5. Some TTL gates
6. LM335 temperature sensors

I still have to buy the components, but estimate the cost of the course to be R300, this include the above hardware.

You will need to bring a breadboard, laptop and Arduino – shout if you need one of these.

We will start at 9:00 and run till 13:00
