If you are interested in digital design with a focus on computers, take a look at this video by Ben Eater.

https://www.reddit.com/r/videos/comments/688eq4/ever_wonder_how_computers_work_this_guy_builds/?st=J33580O9&sh=82ff497b

Ben posted an entire video series which goes through building that computer from scratch. He also has an accompanying website. The computer is based on the design laid out in Digital Computer Electronics by Malvino. The book is out of print but you can find a paperback version on Amazon for fairly cheap. In it, you'll learn everything from logic gates and flip flops to building SAP-1 (Simple As Possible computer).

I bought it after seeing that video and wanting to learn about how computers work. It's a phenomenal book that explains things very clearly with as few words as possible. If you are interested at all in computer design, I highly recommend it!

Otherwise, if you are more interested in analog electronics, you can't go wrong with Art of Electronics.

Also, any of Forest Mimms' books are exactly what you are looking for. I started my electronics hobby building 555 timer circuits from this book

It looks like you're set up as far as it goes for electronics (projectors, a TV, and hopefully at least one computer) so I wouldn't waste any money there. Look for things that are reusable and don't have a high cost of upkeep.

Basics

First and foremost set aside some money for classroom basics that will be useful for any type of science lab.

  • Safety goggles
  • Good quality rulers
  • Tape measures
  • Stopwatches
  • Duct tape
  • Wire clips
  • Cheap multimeters
  • Battery chargers

    Life Sciences

    This is probably the cheapest subject to teach since a lot of the things you'll cover can be grown in coffee cans and mason jars. You'll need flower pots, some spades, watering cans, and some grow lights if you don't have good natural lighting. You can do simple and cheap projects like a tabletop biosphere with some mason jars. You should probably get one decent microscope with a camera you can hook up to a computer or directly to a projector. The students don't need to learn to use a microscope, they need to learn about whatever you're looking at with the microscope.

    Physical Sciences

    If you want to teach the kids electronics buy this whole series of books and several of these bad boys. The Electronic Playgrounds are fantastic for teaching basic electronics because they don't need any soldering, are very versatile, and best of all reusable. If you lose some of the wire they come with just clip your own. IIRC the instruction booklet gives all the gauges different wires.

    Earth/Space Sciences

    These sciences are larger in scale and scope than you might be able to demonstrate in the classroom. You might buy a cheap weather station and make a project out of keeping track of the readings. Over the years students will be able to compare their measurements to those of classes made years prior. This is also a place where decent software or just some good imagery will help teach the subject.

    Check out the following sites for some idea for experiments/demonstrations/activities and then work backwards from there. Figure out what you would need to perform experiments you think will fit your lesson plans and then build a shopping list. There's a multitude of science demonstration projects you can do very inexpensively. If you're smart with your money you can fund your science lab for the next few years even if you've got to spend all the money right now.

    Exploratorium Science Explorer
    PBS Kids Science Experiments
    Hands-on Activities for Teaching Biology to High School or Middle School Students
    National Geographic Lesson Plans
    Scientific American Bring Science Home


    Get a class subscription to Make magazine, National Geographic, Astronomy Magazine and whatever else seems appropriate. Build a small science library in the classroom. Get some good science oriented DVDs. As a practical matter you might also want to get a nice locking cabinet to store whatever nice new things you end up buying. It would be horrible to spend your grant money only to have all your new expensive equipment stolen by some asshole.

I built something similar a few years back. I just wanted inexpensive blinking lights to skater around. You probably can't do much better than a 555 timer. A quick search will turn up hundreds of schematics (try terms like this )

One of the best resources would be Forrest Mims. If you "look inside" and go to "first pages" you will see pretty much exactly what you need. And if you decide to dig deeper into electronics you couldn't start much better than Mims. Seriously, the whole book is a gold mine.

Finally, you may want to look at making a custom PCB. I can't find the files anymore, but you can squeeze 6 copies of the complete circuit on a one 2" x 4" board fairly easily. I'll see if I can't find my layout. Sourcing PCBs is really easy these days. I've used these guys before. They were ok but a little pricey but I was only prototyping so it wasn't a big deal.

EDIT: Seconding what jptdrake wrote. Also, if you goal is a few pounds per box, ditch the PCB. Get some perf board and a soldering iron.

[Glen Ballou's book] (http://www.amazon.com/Handbook-Sound-Engineers-4th-Edition/dp/0240809696/ref=pd_sim_sbs_b_1?ie=UTF8&refRID=17XRBA75YDQ47T230Q36) has a lot of really good information in it. Also , this [one] (http://www.amazon.com/Timer-Amp-Optoelectronic-Circuits-Projects/dp/0945053290/ref=sr_1_1?s=books&ie=UTF8&qid=1406325087&sr=1-1&keywords=timers+and+op+amps) from Forrest Mims is cheap effective. Learning some BEE (basic electronics and electricity) is a great place to start. The one /u/tvdf mentioned has a ton of useful information as well. Good luck, it's a lot of fun once you get started!

So as far as hobby books go, I'd generally suggest the Forest Mims Engineering note books. They have a ton of useful circuits, and mini projects and stuff. Very useful for Tinkering and useful all around. Also pretty easy to read and follow.

u/[deleted] · 2 pointsr/ECE

For a cheaper alternative but not as guided, check out these books as well. Very short and clear examples of different circuits that are used all over the place.

I was at the same point you were at so I started working through every example in the timers and op amps book. It helped more than I could have imagined! You can buy a dozen 555 timers and 741 op amps, a breadboard and some jumper wire and make half of the circuits in that book for under $30. Very useful stuff. It will also help you narrow down what sub fields of EE you enjoy.

Learn from as many different sources as you can find. I recommend Forrest Mims's books (one) , (two) , (three)

Beware that most SPICE simulators focus on very simple 2-terminal and 3-terminal electronic devices: resistors, capacitors, inductors, transistors. But in today's modern world, we design electronics using VLSI integrated circuits, and these are seldom available as SPICE models.

So you will be able to SPICE simulate transistor circuits like the winkie-blinkie thing you built years ago. You'll be able to SPICE simulate opamp circuits, and 555 timer circuits. But not much more, because you won't have the requisite simulation models. Eventually you'll have to build real circuits in the real world and test them out in reality.

If you're an experienced software engineer then you can handle the calculus-I level math needed to understand "real electrical engineering" as practiced by non-hobbyists. After you get somewhat up to speed designing and simulating and building circuits that work (say, in 9 or 12 months), you can start to read college EE textbooks and begin to understand what SPICE ".AC analysis" actually is & why it's useful. You'll learn what SPICE ".FOURIER" is good for, and what it isn't. And so forth.
