[magu]

you are the kindest man on this thread. IT FINALLYY WORKS !!! . the problem has when i buyed the 2 caps (22pF). They give me one 22pF and one 223pF . the 223pF it was the problem . Good bless you and have good luck in live.

[Darrel Taylor]

Hey Mr. Magu,

I'm tired of all the negativity.

It would be really great if you could show a video (or maybe just a "Still picture") of your project working after the Outstanding assistance from Luciano.

Best regards,

[magu]

Anithing is possible ... GREAT THX FOR LUCIANO. --> link to youtube movie removed

[Luciano]

Hi Magu,

Congratulations! I hope your video will be enlightening to many people.

I wish you all the best!

Best regards,

Luciano

We should thank Luciano for his time and generous advices but let's not forget Trent Jackson, whose project is !

[T.Jackson]

How did you manage such high brightness with common diffused (1-5mcd) LEDs? Wondering if you might also be able to post a picture of the copper side of the controller PCB that you original posted.

Hi Trent,

A CCD and your retina have a different light sensitivity. (Spectrum is also different).
What you see here is a video of what the CCD sees.

Best regards,

Luciano


Just for fun:

Beam with an IR remote in a digital camera or a cellular
phone with camera and on the LCD of the camera you will see
the light pulses. (CCD are sensible to infrared light).

[magu]

for those who want to build this project i atach the PCB. PM me when you need to know where the components are placed. Best Regard.

To save long-term embarrassment for various parties involved, I have pruned this thread - if you don't like it well that's just tough!

Congratulations to Magu for accomplishing a difficult project fraught with obsticles. Commiserations for not getting a decent mark for it - you desrve better for your perseverence.

Congrats too for Trent for posting such a complex project.

And Luciano - well, you're an Angel...

[Melanie]

You make the board, you buy the bits, you stick it all together, you write your program, you waste a chunk of your life... why?

Can anyone beat the equivallent of $35?

[Acetronics2]

Hi, Mel

"Aliens" do think other way than us ...

LOL

Alain

PS ... I remember having seen that about µChip 16Bits Contest adds << If you want to have your name in the magazines ... etc,etc >>

may be a possible answer ???

[T.Jackson]

Starting to think that things are really cheap in the UK. The publisher of the EPE magazine offered me the frightful petty sum of 50 pound per project. Apparently, in the UK, you can buy a Mitsubishi 3000GT (in top condition) for about 3,500 pound . In Australia, you can pick one up in mediocre condition for about $25K The UK - a bargain hunters delight?

[T.Jackson]

"Aliens" do think other way than us ...

LOL

Yes, "Aliens" like myself do tend to think a bit differently. Apparently, if I stand on my head and drink a glass of water at exactly midnight, I begin to levitate in a diagonal direction, eventually reaching an altitude of around 25,000 miles before I start to turn green.

Don't ask me how i get back down, believe me you don't want to know.

Hi, Trent

WE KNOW THE TRUTH ...

USD 12!

USD 17.00!

Luciano

Minimum order of $50, meaning you have to buy 3, plus shipping, gets you $61.50USD total.
Still it only comes out to $20.50 each.

I'm actually abandoning all thoughts of doing a KIT for this project. My cost price (based on a quantity of 100 pcs) works out to be around AUS $75. Add a margin of profit to this, plus shipping - no one is going to be interested. I pushed pretty hard for some good prices on the components too.

so i start testing magu's project and sometimes, when i program the message to the eeprom, it starts scrolling from 2 places at the same time: right and center, with the same text. The reset and program buttons have already been pressed, the led indicator stays lit and blinks as normal... I saw that only a power off for several hours or a reprogramming of the pic solves the problem. Is this normal? The pic programmer can be found herehttp://www.adelaida.ro/product_info.php?cPath=32&products_id=525&osCsid=d 2b14521643163ea5ce594e52ff9388a

[magu]

i want to delete my post with the led display from this forum !!!

[Melanie]

magu. You only need to post your request ONCE - not half a dozen times in every category and in totally unassociated threads - in order for it to be read. You made a valuable contribution to this forum, you found some errors posted by others and put in commendable effort that was recognised by many people. In fact, if anyone else wants to build the same project, they won't fall into the same difficulties you had. So to the greater good of the forum I think it should remain. It's also a good reminder to all forum members that if you post something on the internet, it becomes public domain - so good or bad, think before you post.

Hi Magu,

I have verified the thread and personal info has been removed.

I'm sorry Magu, that is NOT an option for the reasons I've already stated. If you no longer wish to contribute to this forum, that is your choice - just don't log-in here anymore.

I know, but where do you draw the line...

Brings to mind the story of the American woman (it had to be!) who put her pet dog in the microwave to dry-off and wondered why it died. She then sued (successfully!!!) the manufacturer because they didn't explicitly say in the manual not to put your pet cat or dog in it!

Children all over the world are forever being told don't give out personal details, and what do the adults do... they give them youtube (I just love the nerd with the dry-ice bomb who blew himself up) and myspace and forums and the like...

The world is full of stupid people... have we really got to spend our lives holding their hand?

Hi Melanie,

The real purpose is to protect the owner of the forum against unpleasant surprises.

My preferred one:

Melanie,
"Brings to mind the story of the American woman (it had to be!)"
Why would it have to be American?

But we do have an old saying over here-

Anything you say can and WILL be used against you.

The world is full of stupid people... have we really got to spend our lives holding their hand?

Yes, right to the edge of the cliff.

I just spent the last...oh....hour or so reading this "Train Wreck" of a thread.
(and the associated like to the scene of the crime)

All I gots to say is this:

Some of you involved in this thread are quite possibly the most kind and generous people I have EVER came across in my entire life. You should all get an extra brick for your hourse in heven...Really. (I wish I could say that I would have acted the same....Gives me something to think about.)

Some of you (And you know who you are) Should be so ashamed of yourself Its hard to imagine you had the guts to even come back and say "I am gone". Its no wonder why you would want your post removed. If I had STOLEN someones hard work and took advantage of their good nature I would feel the same way.

I know that this thread is basically dead. No post for about a month. I also know that my contribution here is "basically" (pun intended) useless. But I just wanted to voice my support for the many and my total disdain for the few.

And I think a special Kudos should goto TJ for making the attempt!

And a big thanks to Melanie for using her super powers to make sure these threads are documented fair and correctly. Its damn nice to know someone like her has your back. We should all send you a pound of good coffee beans! (keep those super powers going!)

Best to all...Who deserve it.

WOW! I registered just to post on this thread. (i was going to anyways) i just had to comment, you people have more patience than i. and better observation skills. i wouldnt have noticed the effort magu put into his board as luciano did. i've been reading posts for months now and finally had to say thanks! i've learned so much from luciano, melanie and many others. thanks T. Jackson for this thread and more learning opportunities.

[selim]

Thank you T.Jackson excell work

[iulisan]

Hello.I build the project as indicated by : T.Jackson , Luciano and Magu etc.I did all the tests indicated in the previos threads and I think it will work with just a litlle help that I will ask from anyone...The problem is : when I start it all the LEDs flash with no sense , when I put the board in program mode the led stays on after it blinks for three or four times but the software tells me that the port is not found or is it in use but it isn't so.I belive that if I solve that problem I will finish the board.I dit test the software on win 98 and xp.Mayby if i can find an image of an 24lc256 that works i can burn on my eeprom and see what happens.Thanks a million times.

[iulisan]

There is no one willing to help me ? Is there no one there who has build the display ?!?

A little bit greedy aren't ya? It's only been six hours.

If you read the thread (yes all one million posts), you'll see that while the initial posting of the project had an error or two, all issues were successively solved.
There's even step-by-step troubleshooting in there somewhere.
