I'm guessing it had something to do with a crazy fusion reactor or something...

Anyone done A5 yet? The part where it goes
is confusing me, cause as far as I can see, the first two are actual connections! Also, does the NAND IC consist of four NAND gates? Do we use them all? In our hardware handout it looks like a single AND gate, then in stage 2 of the flow chart he shows two NAND gates, and then, in the NAND IC schematic I can see four NAND gates!?!

0_o OMGz confusion.

I thought A5 was a terrible assignment, but I give out about everything. I Understood everything we did in the lab pretty well (like I think we did use a single AND gate) but the assignment just made it more confusing. The color coding was boll0x, why not just give us the schematics we used in the practical and let us work out once again how the circuit works instead of leaving us to blindly say "Well Pin 3 has the same color as Pins 5 and 6, I may as well connect them." Nothing is learned by that.

A) Because most of a year won't understand a schematic
You where meant to have the schematic and when I was demoing the course I emailled it out to people, so you could just straight from scratch if you wanted.
C) The handout students had was similarly colour coded, and the idea was that if you at the very least followed the colour code, you'd get most of the marks.

I hope that doesn't mean what it means.
Was I right then in thinking that those first two are actual connections? I'm pretty sure those are right, it's the whole rest of the thing I'm worried about. The hardware handout diagram looks nothing like the webct one. Of course. I mean they wouldn't want to make it any way do-able or anything...

It's a peace of piss, and if you put the circuit together or even know how it was put together originally, you'd have no problem.

Seems to be the same this year too.. or do they take it in to account if you fail 2E10 or something..

edit: Just dug out my A5 there.. Its actually really really short..
I do remember loosing marks tho for not saying what pins were connected to the power source.

Concept problem. There was a one power pin and one earth pin, however their were also other pins connected to 5Volts. These pins did no supply power, so were no the power pins. So students assumed anything connected to 5Volts could be ignored.

Tbh, Its head wrecking that the assignment is given out in this week of term, it was meant to be handed out in Easter to allow students to do it as while they had the board in front of them.

Yep.

Yep that sucks. But it doesn't surprise anymore. The whole 1e9 course felt thrown together in a random mess. Actually, a lot more things felt thrown together in a random mess, I'm talking labs, tutorials, important emails, details of what's required of us, etc.
I think I'm beginning to understand...

Same thing last year.
