5 Mins to ask questions..

Open Source Hardware for academic

projects

–What do you expect me to talk about?

–What are the requirements for a FYP and

Master Thesis Projects?

Can you relate this to your life in university?

Learn???

A ca de mia

• Academia is the nationally and internationally recognized establishment of professional scholars and students, usually centeredaround collegesand universities, who are engaged in higher education and research.

You need to learn details on the components of the system you are

going to create as a professional, and you also need to learn to

integrate those components as a whole and make sense out of it

So…let’s see if you could make sense out of

my presentation…..

Agenda

• Definitions

• Open Source Hardware

• Project Management

• Key Take Aways

The Electronics Landscape… by Prof. Anant Agarwal (MIT) from Circuits and electronics open course ware

System Architecture Physical Devices

Picking a topic

Future Hardware Trends

– 3D Printing– Consumer Electronics (Mobile Phones, Kitchen

Equipments..etc)– Health and Wellness– Home – The Internet of Things– Mobile Accessory– Life Logging (Quantified Self)– Toys and Games– Wearable Technologies

Electronics Hardware Deliverables

• Documents– System Architecture

• Interfaces? I2C, SPI, UART etc etc• Power 12V, 5V, 3.3V, 230V, 400V etc• Controls PWM, Digital High Low etc

– Schematics– Bill of Materials– PCB Layout– Wire Lists/Wiring Drawings

• Physical Parts– PCB Assembly– Encasing– Wires– HMI

• End Product

System Architecture Functional

Open Source?

OSHW Definition

Open source hardware is hardware whose design is made publicly available so that anyone can• study, • modify, • distribute, • make, and • sell the design or hardware based on that design.

The hardware’s source, the design from which it is made, is available in the preferred format for making modifications to it.

Ideally, open source hardware uses • readily-available components and materials, • standard processes, • open infrastructure, • unrestricted content, and • open-source design tools to maximize the ability of individuals to make and use hardware.

Open source hardware gives people the freedom to control their technology while sharing knowledge and encouraging commerce through the open exchange of designs.

Open Source Hardware Layers

Silicon Chip Level

Functional Level

Sub-System Level

Product Level

Product Level Examples

• 3D Printer (MakerBot? Reprap?)

• Drones (AR Drones?)

• Mobile Phone (Open Moko?)

• Vehicle (Tabby?)

• RF (HackRF?)

• Instruments (RedPitaya)

• Renewable Systems (Opensource Ecology)

Open Source Hardware ExerciseLook at the catalogs and you can ask questions

• Type in the links in your mobile phones

• Figure out those you found there if they are at the…

– Silicon Chip Level

– Functional Level

– Sub System Level

– Product Level

….sub system level might be more suitable for FYP, for master

theses..product level (integration) or functional level (research) might be

a better approach

Constraints are everywhere in every project, embrace them to push your creativity

Thesis/FYP requirements

Budget???NYE??

Lin Yar Ma???

I have other things to do???

The idea of iterations

Projects?

The devil’s in the details

I really got over the “get into details right away” attitude after I took some drawing classes..If you begin to draw the details right away you can be sure that the drawing is going to suck….you should begin by getting your proportions right for the whole scene, then you sketch the largest objects in your scene up to the smallest one. The sketch must be very loose at this point. Then you can proceed with shading which consists of bringing volume to life….do it until the volumes are there..work from large to small…always…

-Patrick Lafleur, Creation object Inc (from Signal vs. Noise) [getting real 37 signals]

Key Take away’s…

• You are at the center of the academic project you are working on, you need to know where you are going, you need to decide what is important for you, you need to use the information wisely

• Constraints are everywhere in every project, embrace them to push your creativity
