I used to wear one everyday, but stopped after I got my cellphone. I am annoyed because the watch always get stuck everywhere in narrow places, plus it's annoying when I wear winter clothes

Ah for me, I don't even own a mobile phone.

Thanks all who replied. Man, it is hard to find people who still wear these calculator watches.

Yup. I think the issue, though, is how scientific calcs got cheaper over the years (other than TI ones) and the Casio calc watches did not elvolve at all. So most people would rather get a $5 scientific calc and use that rather than relying on a Casio watch. If Casio watches added more functions, then maybe  they would attract more people.

Plus, nowadays you got graphing calcs that most high school students get at one point, and those calcs can play Portal 2D, Doom (or clones of it), Mario, RPGs and plenty of iPhone game clones. Of course graphing calcs are much more expensive, but the fact graphing calcs can play such advanced games kinda make calc watches less attractive to people.

@Keoni I hope you get parts soon so you can make your own watch.

People take their big caclulators everywhere? I only needed a sample calculator, scheduler, alarm, etc.

I dont know about other people, but I carry my prizm with me in my pocket almost everywhere. and it is my calendar, todo list, alarm clock, and calc thanks to gbl08ma's utility addin.

I hate how the screen gets covered with lint whenever you keep it in your pocket for a while. I'm thinking of making a new cover for it that keeps sweat, lint and loose change out of it.

4. Why are we the only calc forum that has IRC? (that I know of)

(4) Cemetech has one, but it's hidden behind their SAX chat widget. I think it was Omnimaga that followed suit with OmnomIRC. But ours is more obvious because it is more awesome.

Hey! UCF has an awesome IRC widget too!!!

It's a minor one but somewhen ppl started to call me "a bridged one" and it stuck to me for a while

its "THE BRIDGED ONE", not "a bridged one."

If any CP300 has a SH3 processor and some add-ins were made without the official SDK, then those add-ins will most likely stop working on newer Classpad 3xx calcs, like what happened with some FX-9860G add-ins.

Exactly. CP300 addins do not work on the CP300+.

Soon rather than later, we'll get all these graphics capabilities for free (!) on cheap android-like systems (<$50). Then the golden egg math business will go down the sewage drain. Here is just the beginning: https://play.google.com/store/apps/details?id=com.algeo.algeo&hl=en .

It'll take a while for those to be allowed on tests though...

Wow.

Do you think they'll give these away like they did the prizm's?

BTW, I cross-posted this on UCF, and kept a source attribution for you.

I am getting the same problem.

Firefox 17.0, Ubuntu 12.04

OK, I am trying to learn how to do 3D using this guide, and  have gotten to the part for rotating around a point.

The problem is, all it seems to be doing is skewing my cube.

Here is my code:

-- base functions
local clear = zmg.clear
local drawCircle = zmg.drawCircle
local drawLine = zmg.drawLine
local drawPoint = zmg.drawPoint
local drawRectFill = zmg.drawRectFill
local drawText = zmg.drawText
local fastCopy = zmg.fastCopy
local keyMenuFast = zmg.keyMenuFast
local keyDirectPoll = zmg.keyDirectPoll
local keyDirect = zmg.keyDirect
local makeColor = zmg.makeColor
local floor = math.floor
local sin = math.sin
local cos = math.cos
local pi = math.pi

-- major vars
local key = {f1=79, f2=69, f3=59, f4=49, f5=39, f6=29, alpha=77, exit=47,
optn=68, up=28, down=37, left=38, right=27, exe=31, shift=78}
local color = {bg=makeColor("white"), fg=makeColor("gray")}
local exit=0

-- 3d vars
local move = {x=50,y=50}
local piv = {x=0, y=0}
local angle = {z=0}
local roffset = {x=0, y=0}
local x = 0
local y = 0
local xd = 0
local yd = 0
local scale = 1

-- 3d arrays
local cube = {x,y}
cube.x = {-20, 20, -20, 20}
cube.y = {-20, -20, 20, 20}

-- functions
local function d2r(angle)
return angle*(pi/180)
end

local function drawCrosshair(x, y, size, color)
drawLine(x-size, y, x+size, y, color)
drawLine(x, y-size, x, y+size, color)
end

-- 3d
while exit~=1 do
keyDirectPoll()
clear()

-- SPLAT BEGIN
for i=1, 4, 1 do
xd = cube.x[i]-piv.x
yd = cube.y[i]-piv.y
roffset.x = xd*cos(d2r(angle.z)) - yd*sin(d2r(angle.z)) - xd
roffset.y = xd*sin(d2r(angle.z)) - yd*cos(d2r(angle.z)) - yd

x = (cube.x[i] + roffset.x) / scale + move.x
y = (cube.y[i] + roffset.y) / scale + move.y

drawCrosshair(x, y, 5/scale, color.fg)
end

if keyDirect(key.left)>0 then move.x = move.x-2 end
if keyDirect(key.right)>0 then move.x = move.x+2 end
if keyDirect(key.up)>0 then move.y = move.y-2 end
if keyDirect(key.down)>0 then move.y = move.y+2 end
if keyDirect(key.f1)>0 then scale = scale*1.02 end
if keyDirect(key.f2)>0 then scale = scale/1.02 end
if keyDirect(key.f3)>0 then angle.z = angle.z-1 end
if keyDirect(key.f4)>0 then angle.z = angle.z+1 end
if keyDirect(key.exit)>0 then exit=1 end
-- SPLAT END

drawText(1, 1, angle.z, color.fg, color.bg)

fastCopy()
end
