Talking Meat Thermometer - Circuit wizard help

Hi everyone 
I am doing a project in university and i wanted to make a talking thermometer which told a blind person what temperature the meat was. 
At the very best i wanted it to have different functions for chicken, beef and pork. (So they can cook a medium steak and then a safe temperature for chicken, although the temp for chicken and pork is above that of a beef so maybe i can fit it into one chip. i dunno)
I have to make the PCB myself so i was just looking for any help on how i may do it (maybe a mix of a home made pcb and arduino) Any any tips or advice i may need 
Thanks 
Michael

Hi all - THANKYOU very much for your help.

Sorry for the delay i had a few other projects due an was occupied with them. I decided to drop the talking aspect of the meat thermometer as it would have been to costly for me, i looked at an MP3 player to programme the device and it was £30.

I couldn't use the Arduino as i need to make the circuit myself :)

I have done a Thermometer with a bright 7 segment LED display, i am having some trouble with the circuit though as i am a bit of a novice with circuit wizard.

I have created a circuit but there are a few issues i am having with it.

1 - How can i replicate a 4-digit 7 segment LED on circuit wizard so i can programme a flow chart

2 - Can i do it like i have but use decade counters instead of GENIE E-18 controllers?

whole Pork and beef and fish have the same cooking temperature, 145F.

Anything Ground up, chicken and reheating leftovers 165F.

Pretty easy.

IF link dont work google usda cooking temperatures and you want the fsis link. (food safety inspection services)

Look at adafruit.com for their new thermistor/thermocouple board. There should be a tutorial on how to use it too. You need a fairly good quick reading probe which can be sensed by an arduino. If you attach some kind of sound card or shield/ speakers/amplifier to the arduino you can get it to play back sound bites of your temperature reading. There are a lot of instructables on the Staples easy button hack for voice electronics. I don't know if you can hack into one of those available meat thermometers for the oven or bbq which also have remote sensor probes so you can set it and wait for it to alarm. Good luck.

and take a look at sous-vide arduino cooking controllers, lots of ibles on that too.

using a thermocouple it should be pretty easy, see what the probe is reading at boiling water and ice water, and set your scale to that. Have a cow sound go off at 145 and a rooster crow at 165 and your set.

The measuring portion is marked with a dimple. Might need to be modified for handicapable people to know how far to stick in the meat.

I would imagine farm animals make all kinds of sounds when they are probed.
