I can’t believe I actually counted.

As much as I really want another Chao Garden, I know the monkey’s paw would love to grant my wish. Imagine:

Chao garden. You get 2 chao to start out with. Want to access another garden? $2.99 each. Want more chao? $4.99 per egg. You could feed them the fruit that grows natively in your garden, which raises their stamina slowly, or buy more fruit at $0.99 each. Or buy a fruit tree seed for $9.99, what a steal! Need a pack of tiny animals? 20 for $8.99!

While I doubt SEGA would stoop this low… it’s not completely off the table.

We have a word for that too in English: Tuesday

It makes more sense to me because, when binomials are taught, it’s usually in the form of a variable and a constant.

E.G. a = x, b = 3: (x + 3)^2. When expanded, that’s usually x^2 + 6x + 9, and not x^2 + 9 + 6x.

The “print hello world” equivalent of FPGAs is to make an LED blink. That teaches you how to use an FPGA’s clock, divide it down to a frequency the human eye can actually see, and route it out to a pin (the LED on your board). Then you can experiment with your catalog of digital circuit building blocks using buttons, switches, LEDs, and 7-segment displays. You can make your own custom logic of ANDs and ORs to display different logic.

Some super beginner projects I found fun back in college:

• Create a counter, and increment the counter every time you press a button. That’s the easy part. Then display the value on a 4-digit 7-segment display. It’s harder than it sounds, because you have to learn about time multiplexing! (At any one instance in time, only one digit is on, and the other three are off. Human persistence of vision makes us believe all 4 digits are being shown at once, but in reality, the system cycles through each digit, flashing one on for a few milliseconds, then turning it off and moving to the next one. Implementing this takes effort!)

• Learning Finite State Machines and then implementing your own is fun. I made a “vending machine” state machine once, where different buttons corresponded to inserting different coins, and then once a certain amount of money was put in, you could select which beverage you wanted, the machine would “vend” (an LED would flash), and then change is administered. Another fun and classic FSM is the pattern detector, where you input a series of 1s and 0s, and the machine will blink an LED if it detects a certain pattern in the sequence, say, 11010. This one is a lot harder than it sounds, because it requires a lot of thinking of the different edge cases! If I input 111, for example, the system shouldn’t be like, “well he inputted 111 but I was expecting 110…, so I’m gonna start over”, because I could input “111111010” and the pattern is there, just at the end. This one teaches you how to draw state diagrams and Mealy/Moore machines!

• Then you can get into using peripherals, like RGB LEDs, gyroscopes, graphics on a screen, ethernet connections, etc. You just need to learn the protocols and follow the correct logic in your own logic. It’s a lot of copy and pasting at first, but if you put in the effort to understand what you’re copying, you’ll pick up on it fast.

Really, the world’s your oyster, all you need is a development kit and a program that will synthesize/place&route your Verilog or VHDL.

And if you’d like to start at the very, very beginning, HDLBits is an amazing resource to learn Verilog: https://hdlbits.01xz.net/wiki/Main_Page

Let me know if I can ever be of any assistance :)

FPGAs, love the damn things. They’re circuits that you can re-program at will after they’ve been manufactured! If you build, like, a 2-input AND gate, that’s all it will ever be. It can only take in 2 inputs and AND them together. But with an FPGA, they’re manufactured to be versatile; you “program” the circuit you want to achieve onto the chip, and it will achieve that functionality! You can make a 2-input AND gate, slap it onto a bread board, and have yourself that nifty little AND gate, but if you later decide you wanted it to be a NAND gate, just reprogram the chip and like magic, what was once an AND gate is now a NAND gate. They’re great!
