Did you install the IDE by downloading, or did you restore it from a backup?
If from a backup, delete the preferences.txt file, delete the IDE, and install from a download.

Have you verified the sketchbook location in preferences?

Any security software that could be interfering with the IDE?

I was going to recommend the Hakko FX-888, but I see that you read my mind and picked one up.  smiley-grin

I see no need for diodes if you plan to use this driver as designed.

You will definitely get better performance with a heat sink.
Your heat sink should be sized at a minimum to match the
size of the chip itself.

As for a battery, check the the Ah rating of your proposed battery
compared to what your motors will draw.  It looks like they are
70mA no load, and 800mA stall current.

Did you follow the instructions in the link that I posted?  The only time that I have seen the serial port grayed out is then the drivers are not installed.

First of all, check for software updates, then reboot and try again.  If it continues, delete everything related to the Arduino IDE, download it again, and see what happens.

Follow these instructions

I have no problem setting and resetting file associations for .INO files on Windows 7 Ultimate 64 bit.  I would have to think that this is something wrong in your user profile.

Try creating a new user with admin rights and see if you can make the file association in the new user.  If you can, it proves that something is wrong with your user profile.

That is a Hakko 936 clone from China.

That model is a retired product  It's not for sale any more...

This is it's replacement Hakko 926 clone from China, perhaps you meant this:

Are you logged in with an administrator account?
Also, are the .INO files opening with something else, or asking you each time what to open them with?

That sounds like a very workable project.

I respect the fact that you are reaching for such interesting uses for your Arduino - it is this spirit that leads to great innovations.

The problem has nothing to do with your abilities, it has to do with the regulatory process required to build and operate an EPIRB.  Contact one of the COSPAS/SARSAT partners and inquire about their fees for the legally required testing process -I recommend that you place this call from a seated position.   Unless this is a project that you want to invest tens of thousands of dollars into, then your only option is to break several federal laws, the penalties for which are rather severe.

192  Using Arduino / Installation & Troubleshooting / Re: Still confused about pin names/numbers. on: July 20, 2012, 06:29:15 pm
This shows the pins on the chip, and their equivalents on the Uno board.

There is no correlation between the location of the pin on the actual chip,and their location on the board itself.

ALWAYS refer to the pin number as listed on the board, NOT on a diagram of the chip itself.
193  Using Arduino / Project Guidance / Re: Proto-PIC Starter Kit for Arduino UNO on: July 20, 2012, 12:12:51 am
This looks like a pretty decent starter kit.  The jumper wires, capacitors, resistors, etc look like a pretty decent assortment to me.

I think you would be well served by this starter kit.
194  Using Arduino / Project Guidance / Re: Building a distress beacon on: July 19, 2012, 11:25:29 pm
The design of an EPIRB has to be certified by the USCG, THEN granted a type approval by the FCC.

Take a look at this page:

You have quite a task ahead of you, and for starters the Arduino is NOT a radio transmitter, so I am not sure where you plan to make it fit in this project.

The necessary certification by a test facility recognized by one of the COSPAS/SARSAT Partners will run you an easy five-figure sum by itself.

All things considered, I would have to rate the feasibility as very poor.
