Build Application - DJ_Level_3 - 07-21-2019
Minecraft name: DJ_Level_3
What do you like the most about redstone?: I like
What's a thing you have made which demonstrates redstone knowledge?: I made an ALU with a 7 segment display
What does the thing do?: it is a "computer" that can add, subtract, and take an AND output. It also has overflow control and a way to invert input b. Adding and using AND are done by 1 switch, to subtract, you invert b, carry in, add, and disable overflow control. (thanks to PerihelionOrbit for helping me with the subtraction part)
UPDATE:
Since then, I learned that an ALU needs Flood Cary and Or, so I build a new computer. The new one has 2-bit input and 3-bit output for no overflow, Adding, subtracting, inverting b, flood carrying, OR, and Carry In. It also has a 7-segment display and controls for reading and writing memory.

What do you plan on making for your build trial?: A 3-bit binary to 7 segment display converter.
Do you agree with the rules?: Yes, I do.

I'm sorry but a 3 bit bin to 7 segment display converter is still a simple rom setup. spice it up with something.

Thanks! I also had the idea of connecting it to an adder/subtractor, but I thought it would take too long. Would that work?

Can you do an ALU? It's basically an adder but modified slightly.

An ALU has OR and Flood Carry, right? I can do 4 bit w/ screen if there's time
RE: Build Application - Koyarno - 07-24-2019
invert A, invert B, Carry in are also required for the ALU.

Got it. I'll practice. Does this mean I've been accepted?
RE: Build Application - LambdaPI - 07-28-2019
Will you be building an ALU for the build trial?

i guess so.

Accepted for trial! Hop on the server at mc.openredstone.org and ask a staff member for assistance.
Make sure you know your ALU well, the trialer will ask lots of questions about it.
