Hope this helps some one
It would help a lot more if we knew which LCD modules you are using and which software library you are using.  You might try reposting your link as well since there's none showing up in your first post.

It looks like the surviving capacitor is rated at 16V.  If the input capacitor was also rated at 16v then overvoltage was most likely the problem.

3093  Using Arduino / Microcontrollers / Re: avrdude to load bootloader and a program at the same time on: March 16, 2011, 08:50:19 pm
I'm curious as to why you would want to use the AVRISP to load a bootloader along with the program?  You generally use a bootloader to load a program when you don't have or for some reason don't want to use an ISP programmer.

[Edit] Never mind -  I missed the word "initial" when I read it the first time.

Doesn't the Uno require peripherals containing lead and/or cadmium to function properly?

You haven't given us much to work with.  Some information about the display might help especially since you think there might be a power supply problem.  Specifically, what type of backlight does it have (if any) and how are you powering it?  We have had many cases of wiring and soldering that was not as good as the poster thought it was but we need a photo to check that part out.

Oh yeah, I'm using a 4 digit 7 seg. display module "Common Anode"
Well it looks like you got that part exactly wrong.

If anyone has ever heard of such a thing...
You don't indicate where you live but I assume you have seen a washing machine at one point or another.  If you follow either of the hoses you will find that it is threaded to an electrically operated water valve.

3098  Using Arduino / General Electronics / Re: Voltage divider 101 help, any suggestions? on: March 15, 2011, 08:08:54 pm
Did you ever wonder why the designers of commercial chargers use so many components in their design?  Believe me, if they could get away with a resistive voltage divider they would.

Not sure why you have 4 caps,
A big one and a little one on the regulator input and the same on the output.

...and can't find a wiring diagram anywhere after much googling.
What were you googling for?  You have the parts for a generic run-of-the-mill 'three terminal regulator' type power supply and they are all basically the same.  If you look at the parts connected to the power input jack on the Arduino schematic diagram you will find almost all of your components.  The specific values aren't exactly the same but if you look at a few other schematics you will begin to see the pattern.

We can't see your display so you will have to tell us if it works.

I consider buying a parallel LCD and use left, right and enter button for select (ABC..Z).Any recommend?
You will not be able to accomplish what you want to do without some sort of microcontroller.

The setup is very simple, one ATmega328 with bootloader burned on.
Did you buy it with the bootloader already on it or did you burn it yourself?  If you did it yourself did you deal with the bootloader address correctly and did you set the BOOTRST fuse?

Every time i try to upload a program through arduino to my mini using my FTDI i get the same error message,...
Have you looked through the "Installation & Troubleshooting" section of the forum (where this post belongs)?

Ive tried uploading using the ISP Bootloader
There is no such thing - the two techniques are mutually exclusive.

I can use my nixie tubes off a AA battery from the transformer just fine.
I'm a little confused.  You are talking about nixie tubes, batteries and transformers all in the same sentence.  Unless there are some modern replacements the nixie tubes that I remember were neon devices that required high voltage to operate.  Also, the batteries that I am familiar with produce DC (as does the LM317) and transformers transform AC (or sometimes chopped up DC).

Can anyone help me out, what's going on here?
