Raison 8051 assembler and simulator

Excellent free program (for code size under 4K) that I use to assemble and simulate code. Raisonance assembler (18.5M, expands to 50M)
After you install, save this file of interrupt vector names to the INC directory of the Raisonance/Ride installation. It's for the 80C320, DS89C420 and DS89C430.

I expect this is much more than you want; but here it is, anyway, for the zealot who wants the full story about the Raisonance assembler, compiler & simulator.

Third analog homework assignment (HW3)

scan of single sheet showing four basic transistor circuits.

I recommend you also look at the worked examples on pages 91 and 115 in the lab manual.

The four notes below revisit the material already presented from a alternate, and sometimes rather informal, point of view. There is also some extra information on reading capacitor values, expanded to include surface mount components. The class 2 notes are an update of the lab manual's presentation. They are not required reading, but are posted in the hope that they are helpful to you understanding the class material better.

Note on reading capacitors
C notes: toward intuition about RC circuits

Second analog homework assignment (HW2)

By request here are pdfs of all the remaining lab procedures. Note that the one on FET switches may run in place of voltage regulators--there is sadly not room for both. The Friday lab on PID (proportional, integral, differential) controllers is included. It's very interesting but participation is entirely optional. There is no formal procedure and no specific preparation for the cooperative project. You'll get a short handout to set it up on the day. It's a great deal of fun.

Lab 5: Transistors II and Differential Amps
Lab 8: Op Amps I
Lab 9: Op Amps II: More advanced applications and deviation from ideal
Lab 10a: Op Amps III: Positive feedback and oscillators
Lab 10b: Op Amps IV: Positive feedback II: active filters, and nasty oscillations
Lab 10c: (optional Friday 10 July): Advanced op amp applications: PID controller
Lab 11a: Voltage Regulators
Lab 11b: FET switches

Course Description & Introductory Information
Course Schedule
To get an advance peek at what the course covers, you may want to look at the introductory notes above, and then go leaf through the course's lab manual, which you can find at the Harvard COOP: it's called "Student Manual for the Art of Electronics." This little book gives a pretty good impression of what we'll be doing, day by day; we have made revisions since the date of the book, but the style remains unchanged, and the micro labs are essentially unchanged.
Then you should look at the course's Text, Horowitz & Hill, "The Art of Electronics." This book, with its chatty style but rigorous design practices, defines the approach taken by our course.
Lab 1: DC Circuits
Lab 2: RC Circuits
