Class 2

February 2

Workshop: Programming ATtiny85

Details are in the ATtiny85 Guide.

For this workshop, each studen will need to be given:

• ATtiny85 (DIP)
• 10uF capacitor
• 0.1uF capacitor
• LED (any color)
• 470 Ohm resistor
• 10k Ohm resistor
• 1M Ohm resistor
• Perf-board
• 8-pin socket
• Male header-pins
• Solid-gauge wire

Workshop: Soldering a Programming Jig

Homework for next class

• Finish making your ATtiny85 programming jig.
• Breadboard a capacitive sensor controlling multiple LEDs.
• Post documentation of your ATtiny85 project to your class blog. Email me a link to your class blog no later than Sunday before class.
• Nominate a phrase for the Marquee Sign
• Follow the Eagle Setup guide to get a student license, download, and install. Please do this before class.

Class 3

February 15 [rescheduled]

Lecture: Eagle Schematics

Following along with the Eagle Schematic Design - 1 guide.

Lecture: Eagle Board Design

Following along with the Eagle Board Design - 1 guide. This includes the ability to import a design from Illustrator, so that you can design your board's layout in a software better suited for drawing and fonts.

Homework for next class

• Finish the Eagle design of your Marquee letter (START CRYING):
  • S -- Kay
  • T -- Andrew
  • A -- Matthew
  • R -- Astro
  • T -- Zongze
  • C -- Jiayi
  • R -- Long
  • Y -- Kat
  • I -- Octavio
  • N -- Lucia
  • G -- Hank
• Example schematic images can be found at the bottom of the Marquee project page.
• Export a PDF of your design, and post to your blog.
• Order all materials required for milling, from the Things/Materials page. These include:
  • Endmill and engraving bits (I recommend getting x2 of each type)
  • Double-sided tape (the "permanent" type)
  • Copper boards (ITP does stock these but I STRONGLY recommend getting some of your own and/or splitting with someone

Class 4

February 23 [rescheduled]

Lecture: Bantam 1

Follow along with the Bantam guide:

• Bantam Setup
• Bantam Milling 1

Lecture: Demo the Marquee Letter

The scour pads and solder paste can be found on the floor:

Homework for next class

• Mill your letter PCB.
• Bring your unassembled PCB to class (no need to solder yet).
• [Optional] You can assemble the board if you want, but soldering any parts to your PCB is not required before this class. If you do assemble the board, try programming an animation when you touch the cap sensor and take a video.

Class 5

March 1 [rescheduled]

Solder the Marquee Sign

• Using the manual pick-and-place machine to place components.
• Testing, programming, and debugging an assembled board.

Lecture: Rules of Electricity

Homework for next class

• Build and finish your Marquee letter.
• Bring your working and finished PCB to class, where I will test and assemble the sign.

Class 6

March 8 [RESCHEDULED]

Review/Debug: Marquee PCBs

Individually review each student's Marquee PCB. All working PCBs will be given to me, so that I can assemble the sign outside of class.

Lecture: Rules of Electricity

• Power Supplies

Homework for next class

• Build a presentation (3 minutes) about your final project idea.
• Order everything you will need to prototype your idea.
• Build a functional prototype of your idea. Post a video of it working, as well as any relevant images, to your blog.
