The Toastboard: Ubiquitous Instrumentation and Automated Checking of Breadboarded Circuits
The Toastboard: Ubiquitous Instrumentation and Automated Checking of Breadboarded Circuits Daniel Drew†, Julie L. Newcomb‡, William McGrath?, Filip Maksimovic†, David Mellis†, Bjoern Hartmann† †: UC Berkeley EECS, ‡: University of Washington PLSE, ? : Stanford University HCI Group ddrew73,fil,mellis,[email protected], [email protected], [email protected] ABSTRACT The recent proliferation of easy to use electronic components and toolkits has introduced a large number of novices to de- signing and building electronic projects. Nevertheless, debug- ging circuits remains a difficult and time-consuming task. This paper presents a novel debugging tool for electronic design projects, the Toastboard, that aims to reduce debugging time by improving upon the standard paradigm of point-wise circuit measurements. Ubiquitous instrumentation allows for imme- diate visualization of an entire breadboard’s state, meaning users can diagnose problems based on a wealth of data instead Figure 1. The Toastboard device and accompanying software. (1) LED bars indicate power, ground, or other voltage. (2) A push button triggers of having to form a single hypothesis and plan before taking a scan. (3) Quantitative voltage data is displayed in the accompanying a measurement. Basic connectivity information is displayed software. (4) Components are associated with testers that run on every visually on the circuit itself and quantitative data is displayed scan. (5) The voltage at a selected row can be viewed over time as a on the accompanying web interface. Software-based testing graph. functions further lower the expertise threshold for efficient debugging by diagnosing classes of circuit errors automati- cally. In an informal study, participants found the detailed, frustrating, and time-consuming to debug. -
Electronic and Electromechanical Prototyping
Electronic and electromechanical prototyping Introduction - ECAD Corso LM ‘Materiali Intelligenti e Biomimetici’ – Prof. A. Ahluwalia 4/05/2017 [email protected] After Breadboards: Matrix Boards We use breadboards for quick construction, Matrix Boards for laying out a project so it can be copied to make a Printed Circuit Board. This is a prototyping board, with copper pads in a matrix layout. You solder the components in place, and then simply cut pieces of wire, and solder them to make the circuit Printed Circuit Board The PCB is the physical board that holds and connects all of the electronic components. The circuits are formed by a thin layer of conducting material deposited, or "printed," on the surface of an insulating board known as the substrate. Individual electronic components are placed on the surface of the substrate and soldered to the interconnecting circuits. ECAD Electronic computer-aided design (ECAD) or Electronic design automation (EDA) is a category of software tools for designing electronic systems such as integrated circuits and printed circuit boards. The tools work together in a design flow that chip designers use to design and analyze entire semiconductor chips. Before EDA, integrated circuits were designed by hand and manually laid out. By the mid-1970s, developers started to automate the design along with the drafting. The first placement and routing tools were developed. Printed Circuit Board Design PCB ECAD Software (Ex. Eagle): PCB design in EAGLE is a two-step process. First you design your schematic, then you lay out a PCB based on that schematic. PCB Design (2) Your circuit design software will allow you to output the PCB layout in a format called Gerber with one file for each PCB layer (copper layers, solder mask, legend or silk) to allow manufacturing. -

Getting Started with PCB Design
Getting Started with PCB Design This introductory tutorial is designed to give you an overview Summary of how to create a schematic, update the design information to a PCB and generate manufacturing output files. It also Tutorial investigates the concept of projects and integrated libraries TU0117 (v2.0) February 12, 2008 and provides a summary of the 3D PCB environment and creating 3D bodies for component footprints. Welcome to the world of Altium Designer – a complete electronic product development environment. This tutorial will get you started with creating a PCB project based on an astable multivibrator design. If you are new to Altium Designer then you might like read the guide Welcome to the Altium Designer Environment for an explanation of the interface, information on how to use panels and managing design documents. Creating a New PCB Project A project in Altium Designer consists of links to all documents and setups related to a design. A project file, eg. xxx.PrjPCB, is an ASCII text file that lists which documents are in the project and related output setups, eg. for printing and CAM. Documents that are not associated with a project are called ‘free documents’. Links to schematic sheets and a target output, eg. PCB, FPGA, embedded (VHDL) or library package, are added to a project. Once the project is compiled, design verification, synchronization and comparison can take place. Any changes to the original schematics or PCB, for example, are updated in the project when compiled. The process of creating a new project is the same for all project types. -

I love things that blink, and am in awe of the physics associated with making blue LEDs. Intro: A credit card sized Ethernet Arduino compatable controller board I love the Arduino as a simple and accessible controller platform for many varied projects. A few months ago, a purchased an Ethernet shield for my Arduino controller to work on some projects with a mate of mine - it was a massive hit - for the first time, I could control my projects remotely using simple software. That got me thinking - The Arduino costs about $30AUD, and the Ethernet board cost about $30AUD as well. That is a lot of money - Could I make a simple, dedicated remote controller for much cheaper? Why Yes I could. -
Programming Resume
Thomas John Hastings Programming Resume Introduction: I am a highly motivated self-starter with a passion for problem solving. As the owner of a thriving entertainment agency, Big Top Entertainment, I used coding as a way to automate and improve our business processes. I also designed, built and programmed my own unique performance equipment. Since the pandemic and recurring lockdowns have put live entertainment on hold, I have repurposed my passion for programming into a full time focus. I am looking for a challenge, to be involved in building something, learning new technology and sharing the knowledge I have gained from my own projects. Programming – languages and frameworks: Processing I have extensive knowledge of this Java-based creative programming language. The great thing about Processing is the way you can deploy to Desktop, Mobile, and Cloud with only a few modifications to the same code base. Android (Java) I have seven Android apps published to the Google Play Store, five of which are written in Java. I have developed many more for personal use, including the most recent, CoronaVirusSA, an open source app which graphs reliable stats on the COVID-19 outbreak in South Africa. JavaScript Anyone developing for the web needs to know JavaScript. I am familiar with the Flask back end with Jinja, Bootstrap, JQuery, as well as the excellent Tabulator library for tables. Currently (2020/21) my free time is spent on a couple of entertainment related side projects using this stack. Linux I have been using Ubuntu as my main computing system for over 10 years, both in the cloud (DigitalOcean) and on my Laptop. -

While certain steps require linear progression, iteration and revision of earlier stages also happen.
