Interesting. As a subset of your advice, never touch anything or anyone related to Nigeria.

In general, Canada is worse.

Particularly BC.

The secret is to sell used copies of the "TTL Cookbook" for $3.04! :)

The cover design's kinda neat... I wonder who drew it?

Did you notice the seller? ;-)

Good Will Books? No, I hadn't...!

I have a couple of Don's book that I ordered directly from him back in the early-'90s that he was kind enough to autograph. I can't say I look at the TTL or CMOS cookbook much, but the active filters one gets an occasion visit.

"...our Mission to help those with barriers to employment"

Maybe Slowman could use a copy.

Always thought about buying that one but needed a round-tuit, first. I just use TI's FilterPro, now. Does what I need.

That's the _new_ cover. Mine has the old olive-green cover--I bought it from Rat Shack in about 1975 as a HS junior.

I chucked my TV Typewriter book decades ago

By the time I was in high school, Radio Shack didn't carry's Don's books... although they did carry Forrest Mims (a big book or two and a bunch of "Engineering Mini-Notebooks" --

These days I see they still have Forrest's "Getting Started in Electronics" -- that's kinda cool...

Maybe there's a need for a companion book, "Getting Started in Optoelectronics" by you. :-)

(Oddly, both of the college classes I took in optoelectronics -- one just a survey lab and the other on fiber optics -- were useful, but really pretty mediocre. I imagine I've related on here before how, for the lab, I built a heartbeat detector using an IR LED & phototransistor positioned against your finger, was really pretty happy that it worked at all, and was rather ticked that I was knocked down a grade because the TA thought it should have a digital counter to display beats per minute rather than just the big LED and piezo beeper that it activated on every beat. What the hey!?)

I have a couple Forrest Mims books from around the turn of the century that I bought when I was first getting into electronics - there's one that appears to be a compilation of the 555 timer book and two others called "Timer, Opamp, & Optoelectronic Circuits & Projects". Publication date 2000.

I'm going back to school this fall at the age of 30, so I'm sure I'll have the same experience but to add insult to injury it'll be a TA 10 years my junior!
