Sculpted Roman Numeral Cake? Answered

I need help with a cake. I want to make a cake in the shape of 3 Xs for my Brother in law's 30th birthday (like the roman numerals: XXX) Can someone give me tips on how to sculpt the cake? Should I bake a square cake and then cut it? Or should I attempt to build an X shape into a square pan? Any potential issues you can foresee? I've never used fondant before but I think there are enough instructables on that subject already.

Pulse detonation(numerical simulation)

Hello everyone iam a Msc student now, i have done many projects over pulsejet engines which you could see in my instructables list. Now i have decided to do a project over pulse detonation engines, before beginning with the real one i thought that making a fluent simulation will be better. I have several tries to create the detonation front and atlast i succeeded in creating one. Take a look at the attached pictures which shows the development of a detonation front inside a long tube of 100cm. Further works will be updated soon. Want to see the sequence of deto wave formation please follow the link... http://www.4shared.com/archive/a4unsF-9/sequence1tar.html?

Numeric keypad- how to block signal? Answered

Here is the story. We needed a cell counter in out lab that counts 50 cells, most diff. counters do multiples of 100.  I found a diff counter online, altered the java script so that it counts 50cells and bought a couple of numeric keypads to use with it since the computer keyboard isn't situated well for use while we are on the microscope.  So the problem is that the two mics we used this with are set up in small room and the keypads are too close together so that if you are using one, both computers pick up the signal.  So if two people are counting at the same time the counter picks up the typed input from both keypads.  So my question is, is there a way to block the signal from reaching the other computer? They are both Targus Wireless Numeric Keypad.  They are wireless and use radio frequency.  I tried tinfoil that didn't work. The computers are spread out as far as they can.  That is the only room we have for them since they are fluorescent microscopes and we need to work in the dark.  I guess the obvious solution would be to just replace them with non-wireless but I was hoping that we could save money and try to get this to work.  Wired ones may be awkward to use due to space constraints too. Thanks

electronic numeric display board for volleyball

I have searched the Internet hard for a reasonably priced electronic numeric display board to no avail.  I am interested in constructing a remote control scoreboard for volleyball similar to basketball scoreboards deployed in high schools.  For many years I have played and continue to play a LOT of drop in volleyball at various local Rec Centers.  It would be great to be able to keep track of the score with a remote control device in your pocket while playing the game. Alternatively please let me know of any high schools being torn down which could be an opportunity to save a basketball scoreboard that would otherwise be relegated to a land fill site. When you think about the utility of such a device, why hasn't this project been done before?  Maybe it has and if you have any info then PLEASE forward.   I would seriously entertain any posted price for such a completed device if it exists as the hero factor is huge.  The advantage of building it yourself is that you are in a position to manufacture duplicates for others and you become the repair man. The bigger the display board, the better.  I know they exist but are mostly cost prohibitive.  At this point I am prepared to start with a small display for the prototype in order to get this project started since I am very enthused.

Why or why not does .9 repeating equal 1?

I already posted this as a regular question, but someone told me to make it as a burning question, so here it is: HI! I am wondering if .999...=1? I mean if 1/3=.333 and 1/3+1/3+1/3=3/3 and 3/3=1. So wouldn't .333...+.333...+.333...=1? But it actually equals .999... not 1. I googled this question and I got many different answers ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ For example...(someone wrote): I'm not really into math, but a friend brought something up to me today that really seemed very strange. (For the duration of this post, .999 will mean .9 repeating unless otherwise specified- just for the sake of ease) .999=x 10x=9.999 10x - x = 9x 9x=9 1x=1. .999 = 1. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Someone else wrote: Numbers are fake. They are a manifestation of our minds to describe something, similar to words. Just because we say "red" doesn't mean something is red. what is red? Languages and math are very similar. Math is universal...at least for our planet though. .999~ does not = 1. But what .999~ repeating represents, does in fact equal what 1 represents. No-one will ever be able to comprehend infinity, os its time to stop trying. Think of space and the universe. IT IS GROWING. how can it continue to grow with no stop? what is there to contain it? WE need something to contain it in order for us to understand it. We need a stopping point, but there is none. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Another person wrote: In your proof that .333...*3=.999... you forgot to include the fact that .3333... is NOT 1/3. 1/3 if not a number that can be turned into a decimal in any way. I thought someone might like to know this fact. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ And the last person wrote: Just a pedantic point the equation for differentiation is given by lim x->0 [f(x+h)-f(x)]/h, it has the minus sign. It is after all just telling you the slope and is no different really from doing simple trig using the tan function. Here you just take a really small triangle. As to the 0.99~ thing, this is really just writing the supremum (spelling might be off) of the numbers less than 1. Just think of it as taking the smallest number 'n-word' than 0 away from 1. They are not identical for if they were we would not have a continuous number line, but rather a dashed one with lots of wholes in it. I could simply argue that 0.99~8 is just as close to 0.99~9 as 0.99~ is to 1. For those who really want to understand go and look up supremum numbers and the axioms of the real number line. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ So who is correct? Do you agree that .999...=1? Or .999... does not equal 1?

Library for easy alpha-numeric display on an LED matrix?

I'm looking for a library for either the Arduino or AVR line of microcontrollers, that enables easy display of scrolling text on a 5x7 or 8x8 LED matrix.  Here's what my requirements are: - The library should contain a table of common alphanumeric characters (alphabet, numbers, and maybe some symbols) - A function should call up any number of letters to form words or phrases, like this: Scroll(H,E,L,L,O,sp,W,O,R,L,D); - Once the function is called, the text automatically scrolls across the display - The function can be called from anywhere, like if/then statements, case statements, results of random numbers, etc. - Additional modifiers, like scrolling left or right, speed, and repetition would be nice to have but not necessary. I've searched the AVRfreaks forum and various Arduino forums, but haven't found what I'm looking for.  So far anything I've found is basically hard-coded bit-banging, making it difficult to change the text and impossible to store more than maybe 100 total characters.  My goal, with a set library of characters, is to have the ability to play back hundreds or thousands of characters, arranged as single words or phrases.  They should be as easy to change as typing in a new sentence in plain language into the code.   So, has anyone come across such a thing?

Cheap and easy way to send alpha-numeric messages to pc?

Hi, Ok.  This is driving me crazy!!!  I've been on the computer now for 7 hours straight, going deeper and deeper into a problem that on the surface really shouldn't be that difficult.  I think I'm pretty close to losing my mind... So here's my issue.  I work in a busy restaurant (everyday we serve over 700+ people in 5 a hour timespan!) and I've developed a program in .net that automatically seats guests.  The software takes care of groups of diners, equally sharing guests amongst  servers, seating best tables first and so on etc etc.  Any way, all the software user has to do is take the guest's room number and name, the code does the rest. Here's my issue.  When the restaurant fills up, a queue quickly forms.  The only way for me to find tables that are open and ready to be seated again is to walk around the restaurant and do an update.   I have to do this every 10 minutes which is very inefficient and time consuming. This creates chaos as the hosts are running around and being told to do different things by different people. The hosts are flipping tables when they should be hosting tables, and vice-versa, they are coming up to the front to walk a guest in when we have no open tables  I came up with the idea of having the floor supervisor send a message wirelessly over the network using an old winmo phone - she simply types in the table number, clicks send and then the table is marked open in the program at the front of the restaurant.   This solution is the best I could come up with but it's not perfect.  In an ideal world, each server would have a way of telling me which table is open the second it is ready.  It would be too costly for everyone to have a phone plus it would look inappropriate to the guests.  The crappy software we use on the computers on the floor is closed and can't be altered.  I need a cheap and easy way for the servers to be able to send a message to the computer at the front of the restaurant. And this has lead me on my merry dance around the internet - going from ardurino to bluetooth.  From z-wave to usb dongles.  There just doesn't seem to be a system out there that fits my problem.  The  closest I got to a solution is using 433mhz keyfobs which cost about 5 dollars each from china (the same ones used in home automation to open doors and switch on plug sockets).  When a table is free, the server punches the table number on the key fob and the software updates itself.  This lead me into the murky world of 433MHz - it seems incredibly complicated and difficult to do with protocols and drivers and everything else. Has anybody done anything similar to this? Another solution I came up with is having a button on each table.  Again, when the table is free, the server presses the button and the table becomes free in the software at the front.  Is there something like this on the market? Another idea would be to have wireless web cams around the restaurant so I would be able to see when a table is free.  This is a great solution except it isn't fully automated and, again I don't think management would like the idea of cameras all around the place. Can anybody point me in the right direction?  Has anyone faced a similar problem and if so, what did you do to improve things? If you got this far in the message, thanks for reading this rambling nonsense but I really am at my wits end!! Thanks again,

I've been searching and reading on how to etch aluminum.  I've tried the photo paper toner transfer numerous times, but the toner does not stick to my aluminum plate.  I've gone over with my iron so many times while putting extreme amounts of pressure on it, but no matter what I cannot get the toner to stay on my aluminum plate.  Can someone please help me, or let me know a better way of doing this!! Thank you!

How (not) to improve eyesight

We seem to be getting a rash of Instructables claiming to be able to improve eyesight through simple exercises.Please, people, can these stop? The methods were quackery in 1920, and have been thoroughly refuted numerous times since (for example in 1956 and 2004 ), yet, like holistics, pyramid power, magnetic bracelets and a host of other quackeries, they still do the rounds and fool people into falling for them.Please, people, do a little research before posting supposedly medical treatments.

I would like to make a simple relay actuated by a bluetooth connection for opening a garage door. Answered

It would be really handy to be able to make or buy a simple switch that would turn a device on when your cellphone is within range. You could use it to activate a garage door. Or to turn an electric door lock. Or to remote start a car. The possibilities are.... well... Numerous. IF somebody made a device through one of the online prototypers, I would pay 50+ bucks for one of these.

Text display in Instructable PDFs

Why is the kerning (inter-character) spacing of the text in Instructables' PDFs so goofy? Not any of the heads, but all the text. I'm using Mac OS X 10.5 and the text font used is identified as Helvetica Condensed Bold Italic. Heads are Helvetica Bold (not Condensed) and they do display correctly. I do not have any problem on my system with Helvetica Condensed Bold Italic used in any other document and no problem with numerous PDFs from other sources. And, why not a simple Arial or Helvetica Regular or Plain for the text anyhow?
