Week 3: Sunday, 9/14/25 #

This is the week that Project 1 work clicks into place, with the introduction of (free!) circuit board design software called KiCad. We’ll use KiCad to translate your temporary breadboard circuits into permanent circuit boards. We’ll preview KiCad in class on Monday and recommend that you have it installed on your computer by class time on Wednesday, 9/17. If you’re having trouble installing it, please reach out to an LA or instructor. We’ll also further explore capacitors in class on Monday.

Things due in Week 3:

  • Due Mon., 9/15, 11:59pm, as photo upload to Canvas: Prototype Circuit for Project 1 (Voltage Regulator/Breadboard Power Supply)

Learning goals for Week 3:

  • Deepen your understanding of voltage, current, resistance, and power, as they relate to your Project 1 Breadboard Power Supply circuit (featuring voltage regulators)
  • Build a capacitor charge/discharge circuit and choose resistance and capacitance values to increase its time constant
  • Take a breadboard prototype and turn it into a PCB design using KiCad software

Course website (andnowforelectronics.com) pages to study in Week 3:

Textbook reading for Week 3:

  • From the Scherz & Monk textbook (available here from Tisch Library online
  • Section 3.6 “Capacitors”
  • Section 7.2 “Constructing Circuits” (featuring info on printed circuit board design and construction)

Week 2: Monday, 9/8/25 #

Thanks for a great first day of class last Wednesday. We appreciate how willing you were to lend a hand to classmates once you figured out your own circuit. That spirit of collective learning will take us far this semester.

Course housekeeping:

  • Remember to bring your green box to every class and lab session.
  • Check the Calendar page of the course website to see what we’re doing in class each day and what to study and do every week.
  • Labs begin this week in Nolop on Wed, Sep. 10. Labs are 1 hour. Bring your orange box.

Things due in Week 2:

  • Just the in-class activity uploads to Canvas

Learning goals for Week 2:

  • Describe the difference between a voltage divider circuit and a voltage regulator circuit.
  • Deepen your understanding of voltage, current, resistance, and power, as they relate to voltage divider and voltage regulator circuits.
  • Measure voltage, current, resistance, and continuity with a multimeter.

Resources for your learning for Week 2:

For Week 2, these are the resources we’re suggesting:

Office hours

  • Office hours should really be called “times when we sit and wait for you to come build circuits with us”
  • Kristen’s office hours this week are Fri. 12-2pm in Nolop (but usually 3-5pm Fridays)
  • Brandon’s office hours are whenever he’s in Nolop, M-F, 9a-5p

Week 1: Tuesday, 9/2/25 #

We are excited to start ME 30 with you! Welcome to the course. We’ll send an organizational email to the ME 30 class every Sunday evening. But this first week, we’re doing it on Tuesday.

Course website:

The course website is http://andnowforelectronics.com/. It serves as the required text for the course. It includes:

  1. The syllabus, which lists office hour info
  2. The calendar of topics, suggested readings, and project work due for each class meeting
  3. Notes and brief videos on key topics
  4. Kit component list and data sheets for all components

Electronics kit:

You’ll receive your electronics kit in the first class on 9/3. Bring it back for EVERY class and lab. You’ll return it at the end of the semester.

Labs:

No labs this first week. They will begin on Wednesday, 9/10.

Things due in Week 1:

Your first Canvas deliverable for an in-class exercise: Upload a video from Class #1 introducing yourself and showing us your LED-pushbutton circuit.

Learning goals for Week 1:

  • Build a working circuit prototype on a breadboard
  • Explain how current flows through the pins on a barrel jack
  • Start to make sense of voltage, current, resistance, and power, as they relate to a simple LED circuit

Resources for your learning for Week 1:

In ME 30 we’re aiming to provide a menu of resources to support your electronics learning. We hope you’ll explore and use what works best for you. Some of you may start with the videos we’ve embedded in the website pages; some of you may start by reading a textbook section; some of you may focus on the written website notes; and others may start with broad questions in office hours. Let us know if you’d like help developing a strategy for navigating the different options.

For Week 1, these are the resources we’re suggesting:

NOTE: Many of the website notes pages include mini-lecture videos.
