On Monday May 16th, 19-21:00, I’ll be doing an introduction to transfinite numbers. Topics will include:

• Cardinals and Ordinals
• Cantor’s Diagonalization Argument
• The Continuum Hypothesis
• Transfinite Induction

Transfinite numbers are really cool, since, well they deal with infinity, don’t match your intuition’s about infinity, and have a tendency to drive people insane!

Unlike previous math workshops, there is no prerequisite knowledge for this workshop. It should be lots of fun! I hope to see you there.

UPDATE: Notes from this session as well as a detailed online tutorial have now been posted at:  http://wiki.goodrobot.com/wiki/Servos

To reserve your spot for this free workshop please confirm through eventbrite:

This workshop is for anyone who would like to make things move using hobby servos.  Attendance is free and limited to 11 people. Beginners at any level are welcome, though ideally you will have a very basic familiarity with Arduino (for example, you might have tried something like the arduino blink tutorial).

The workshop will be held at Hacklab (170a Baldwin St) 7pm-9pm April 18th. Hacklab is located in Kensington Market, a few blocks SW of College and Spadina. For directions see:                                   http://hacklab.to/location/

In this workshop we will discuss hobby servos, how they work, and what they can be used for. Then we will use our Arduino (an open hardware platform) to control them. For those interested in working with robotics or making things move, controlling servos with arduino is a great first step.
Please bring:
- A laptop (make sure you have downloaded and installed the Arduino Software: see arduino.cc )
- An arduino (Creatron sells them on College St just a few doors east of Spadina)

I’ll supply a variety of servos that you can experiment with. See you there!

I’m going to be running an openSCAD workshop on April 4th at 19:00.

OpenSCAD is a lot like a programming language except that instead of compiling into software it compiles into a 3D object. You have if statements, loops and functions. For a lot of purposes, it is way easier than using traditional 3D modeling software.

For example, it’s what the Hacklab RepRap is being developed in.

No reservations are necessary. It would be preferable for you to install it before coming (Ubuntu Users: there’s no package in the archives but you can use this PPA).

I hope to see you there!
