Description of meeting:
- General discussion time –
- Question & Answers,
- News (new products, purchases, projects)
- Introduce a component, technique, tip, etc
- Tea/coffee break
- Presentation-1: Using a free, fully functional 3D (& 2D) drawing/CAD package called DraftSight from Dassault Systèmes. Demo of drawing a mechanical part from scratch. DraftSight provides similar functionality to Autocad, including compatibility of file formats.
- Presentation-2: Feedback techniques - where Murphy's Law usually fails. This presentation will introduce feedback, a widely used technique in circuit design, particularly how we can get high-accuracy from cheap low accuracy components like operational amplifiers.
Description of Group
Our group is for people to develop microcontroller projects (including the software-programming) – gadgets for fun and more serious purposes. We make machines, using microcontrollers, and other electronics, to do things. We cater for all levels of knowledge, novice to experienced - users helping users. We are a sub-group of Melbourne PC User Group, and we model our sub-group along the style of makerspace.com.
Our monthly Wednesday meetings involve discussion and presentations, usually with between 8 and 15 attending (most of these are not on Meetup, and are therefore not included in Meetup’s apparent meeting numbers).
Our associated Saturday Workshops are informal and hands-on – bring-your-own project/stuff. The Saturday Workshops are a "Maker Space". They are a space to express your creativity, build your own stuff, and investigate ideas. The activities depend on those who are involved and their interests. If you are looking for a space that facilitates sharing of ideas and support, this could be it. (We have some electronic equipment that many starting hobbyists may not, e.g. oscilloscopes etc.) The Workshops are an informal group, a place to work on your project, start a new project, or join a group project.
If you are new to this: microcontrollers are small cheap computer-chips with measurement or sense inputs (e.g. temperature, door-open) and control outputs (e.g. displays, motor control), i.e. all combinations of analog & digital, inputs & outputs. They need very few other components to function, and are in many products (e.g. cameras, cars, toys).
