Battlebots Design Ideas
13 more posts in this thread. [Missing image file: ]
My professor has recently given me $10,000 to make a robot to compete in the Season 2 Battlebots. He originally wanted it to be autonomous, but I couldn't find a way to make an autonomous battlebot work without making it stupidly simple. I originally thought of using a swarm of quadcopters but I later found out projectiles weren't allowed. He now expects something more creative out of me, after I finished designing a dual wielding drum-flipper battlebot. Considering most of my robotics experience involves the Robocup/autonomous quadcopters, I've been hitting a wall thinking of a creative design that my professor will accept (I'm in CS, not MechE, this is all new to me). Does /diy/ have any interesting/creative ideas/designs I could use? I understand this all sounds stupid but I've done a lot of reading on the different types of battlebots but can't seem to find anything that'll stand out.
Graphics Accelerator on FPGA

Hey guys, im trying to make a simple graphics accelerator on my spartan 6 papilio pro dev board, im trying to develop it on fixed pipeline (obviously), I am planing to use opengl for the graphics commands, and only include vertex shading and a ratsterizer, i'll include fragment shading later on if i have time, now what i want to know is how exactly the vertex shading pipeline functions. ( i am realy starting from scratch even the knowledge i have on the topic is only in progress, need serious guidance)

Let's talk about cleaning, consider this a wake up call to those oblivious to neglected aspects of their house and then, perhaps, discuss DIY cleaning methods.
I'm going to bring up some areas of your house and on a scale of 1 to 10, 1 being completely filthy and 10 being immaculately clean, you have to tell me how clean these parts of your living space is. Write a note alongside it explaining details if you desire.
Kitchen, in general
Kitchen stove (on the surface, sides, and underneath)
Refrigerator (inside, surface, and underneath)
Windows and window sills
Hard-to-reach crevices throughout your house
Sides of the house
Keeping your house clean should be a priority. The condition of your living space is a reflection of how you are as a person.
Reconsider the designs of your living space. Hard-to-reach crevices are the devil, they make more work for you and are great places for dust to collect. Don't butt your furniture against the wall, always leave enough space so you could push a vacuum cleaner behind it.

Hobby CNC thread.
So I'm considering buying a benchtop CNC router. Probably a Shapeoko 3 or an X-Carve.
I've done some CNC machining before, but it was 10 years ago in college, and I had professional grade equipment and software.
So I'm looking for recommendations and advice from people who might have one already. I mainly want to do 2-D machining of Fiberglass and carbon fiber. But I'd like the capability to do 3-D machining as well (3-axis) and will probably also work with wood and plastics.
Will the machines I'm considering work for what I want to do?
And what should I be looking at in terms of software. I know Shapeoko and X-carve both come with software but it seems pretty limited, so I'd like something better.
I'm considering Mach 3 for controller software and MeshCAM or Vectric Cut3d for CAM software. Not sure what to do about CAD though, there doesn't seem to be anything at a decent price point between free, heavily limited tools, and stuff like Solidworks and AutoCAD which runs thousands of dollars per license.
My overall budget is probably $2,000 when I get my year-end bonus. It could end up being as much as $3,000, but I won't know that for sure til I get it.
Basically does anyone have any advice/suggestions on getting into this? Would appreciate it.

How does the little indicator on Brita filters work?
It usually has 4 bars, or on some models different colored lights, that count down to when you should replace the filter.
Got into an argument about this earlier, and apparently nobody knows.
It seems like it must either measure how much water gets poured out, or simply how long the pitcher is tipped. Otherwise it's a simple 90 day (or however long) timer that resets when you put in a new filter and push the button. (The digital gauge is not connected to the actual filter in any way.)
I'm on the side saying it's not a basic timer, but somehow measures use.
Does anybody actually know?
I tried this thread on /ck/, but thought you guys might have a better answer.
