Introduction to Electronics Every so often, a device comes along that changes the way we live our daily lives and things are never the same again. With today's digital technology, such devices may come more frequently than in the past - personal gadgets you cannot live without. Whats inside? What makes it tick? How do you find out? In this sharing, Mark will provide an introduction to hardware hacking and why it matters, going through some quick tips on getting cosy with hardware to find out what makes it tick.

Editor's Notes
- #19: Manufacturers rely on the information that is included in the bill of materials (BOM) to build a product. The bill of materials typically includes part names, part numbers, part revisions and the quantities required to build an assembly. Thorough BOMs can include more descriptive information too, for example, the unit of measure or procurement type. BOMs that have printed circuit board assemblies (PCBAs) contain a column for listing reference designators.
- #24: Step 1.
- #26: Turn screws. Void warranties. Open minds.
- #33: Every so often a piece of technology can become a lever that moves the world, just a little bit. The Arduino is one of those levers. It started off as a project to give artists access to embedded microprocessors for interaction design projects, but I think its going to end up in a museum, someday, as a building block of the future world. Arduino allows rapid, cheap, prototyping for embedded systems. It turns what used to be fairly tough hardware problems into much simpler software problems. And its become the poster child of the Maker Movement. The real power is the community.
- #41: Fail fast, learn quickly, succeed sooner By turning abstract concepts into visual forms for validation
- #43: Almost every day, a new product hits the store shelves with the aim to earn name, fame, and of course dollars in the commercial market. However, have you ever wondered what went into getting the greatest and the latest slotted into the market place. Every product, before you rest your eyes on them, undergoes a lengthy and vigorous evolution process. There are some quality checkpoints that a product to be developed has to clear on its way to hitting the market, and they are the product design phase, the product prototyping phase, and the final, bulk manufacturing phase. For entrepreneurs存 after you have an innovative idea for a new product, you need to determine all the details. Here we would like to share some practical questions, which you should ask yourself before you make any move:
- #44: By the high levels, it would be getting an equivalent of a mechanical / electrical and electronics diploma
