### math fromula

Thought this would be an appropriate place to share some of what i thought was interesting information to do with the area of a triangle and how numbers co-relate. To round off a square to 100cm square, one quarter of that area is 25cm square, (10cmx10cm =100/(div)25%=25cm), the area of a  right angle triangle with sides measuring ~7.0710cm,  equals ~25% of 100cm square,  25cm square of area,  (7.0710/2=3.5355 x7.0710=24.9995205). 7.5937 if it is an equilateral triangle. it is a standard size i use,  a handy measurement if you use templates for construction because it in  some way represents a metric increment, thanks, Kim (the formula i used is half the base times the height,  unless im mistaken i recall that is the correct formula?  though i am not a full time mathamatician.  for the equalateral triangle i used a web based polygon area calculator.)

### Boston area Hackers wanted

Via sugru on facebook A production company based in Boston is developing a documentary style project focused on hackery. Basically, they want some mischievous mad scientists with hearts of gold to take their textbook knowledge and apply it in totally bizarre ways to all kinds of everyday materials. Visual spectacles; cool, geeky gadgets, your most crazy and elaborate projects - you get the picture! If you or anyone you know is interested, email casting@powderhouse.net by Feb. 18th (Thats TODAY) with a brief bio, pictures of yourself, and details of any projects you have pulled off in the past. Boston area is probably preferred, but who knows: for a good enough hack, their may be be a travel budget.

### sound-only area and cancellation

I'm looking for advice. (now this is difficult to explain but I'll try my best) I am trying to design a way to have a dance floor in an open area that will have an area where you can hear the music but away from the area it can't be heard. I'm attempting to do this using an array of speakers around the dance floor that will cancel out the music past the dance floor. Each speaker will face away from the area and be equipped with a microphone (directed torwards the main speaker) that then goes through and amplifier and then to the speaker (wired up so that it will emmit an opposing sound wave). This would essentially create a sound barier. I have attatched a picture as a visual aid.

### Maker Faire 2009: Peterson Neon

The first year at Maker Faire (2006) the Instructables/Squid Labs booth was just across from Peterson Neon. (She also works near our old Emeryville digs.) It was incredible watching Shawna Peterson bend neon tubing for signs - lots of fire, slow careful movements that carefully bend the glass to match the angles of her templates, and the occasional puff of air to re-expand a bit of tubing that has softened and constricted at a bend point. The sign is worked from the back, so the front looks properly flat and legible.Check out the video Bilal took to see how it's done.

### Given the derivative of a function, how would you find the original function? Answered

I am trying to teach myself calculus, so I am asking this question. For example, given that the derivative of a function is 2x, you could use the d/dx [x^n] = (n)(x(n-1)) to guess that the original function was x2, but what would you do if you were told that x2 itself was the derivative of another function? Please help me. Note that I am NOT someone asking for homework help, my homework from school is not calculus.

### How do you setup a router? Answered

I have a 54M Wireless router here. It's a TP-Link with 5 ports at the antennae side. The first port is labeled "WAN" and it may mean "Wide Area Network" or "Wired Area Network" or "Wireless Area Network". The other ports are for wired connections. I want to use this router, but my problem is that I can't seem to secure the thing with a password (remember it's wireless). Also, the last time I tried to use it, the whole thing won't work. Well, sure the Network was setup, but the internet won't work. Where do you plug the network cable from the modem to the router, and the PC to the router.  Straightened out: How do you put a password on the router? How is it supposed to be connected? Could you disable the wireless feature? If so how? What does "WAN" mean?                                        - Thanks
