Ah yes, I've completely forgotten about that dinner picture from two posts ago so I'll do that later.
But first!
I've thought about it again, so today I posted on GAM100 about finding for a new partner. o_o; hope it works out yet again, but it's a risk!
Jun Wei is on tenterhooks today; after ditching him at home habitually now because of my sudden love for going to school early, I'd expect him to chase after my tail or at least get to school on time; today he's nearly late for lessons, and he was huffing his way to class.
On top of that he's kept checking his low-bat phone (how it got low is a mystery) for the delivery schedule (receiving a few smashes to the face from my ping-pong ball in the process, lol!), because his new laptop is coming and he cannot wait at all.
Well, at least it saves me a few hours on my audiospace away from "cheedan", "chai dian" and "is that true"... >_>
As if to help him settle back at apartment to wait for the laptop, Professor Schafer reported in sick on Moodle, so we have no more lessons after MAT140 (yay).
But while he skips back to the Ridge happily, I am determined to practice more on the circuits I'm so confused about, so I'm checking in at Archimedes for more practice.
I can't be defeated by a breadboard and so many wires! -_-+
You'll notice a few familiars like the crocodile clip, resistors and LEDs. The one you probably don't know would be the fuse (black crocodile clip connecting it), a switch (blue thing) and relays (in white).
A relay is like a switch changer, pass electricity through the relay on the electromagnetic side (far left edge) and the switch would change. In the first picture, it's a NOR (i.e. A=0,B=0,result=1) gate because it works such that if either switch is turned on, the circuit would break and the light won't turn on because the actual electrical connection (rightmost bottom, coil of red wire), which originally connected to the yellow line, now connects to nothing.
The next two pictures are the OR gate (notice where the yellow line is now on the first relay? And the bottom black line?) and the NAND gate (notice how the circuit will break if BOTH switches are turned on? Remember that NAND is such that only A=1,B=1 will produce result=0)
I know the OR gate is unnecessarily complicatedm but I needed to have a base in making the gates work. The pictures were uploaded in reverse manner. >.<
The AND gate is too stupidly simple to show. Put two wires together, disconnect either and you don't get jack. TADA. LOL.
The one gate I don't really get is XOR, because XOR is such that it MUST be either A or B but not both.
So Junwei finally gets his new lappy! ahhh!! he tempts me to get a new one too! xD The circuit boards are always fun. The DES module originally was supposed to have those too. but i think they took it out because its kinda expensive to maintain those equipment. Might be worth reconsidering since its easier to learn digital logic with a device on hand.
