My 3310 as a light!

[KetS]

Well, this is a proyect that i did some time ago, but now i have enough time to so it to the world.

I did it because i was a bit jelous of a friend's 3200 with torch ligth so i decided to make one for my 3310.

You only need, a solder, a ultra lighting led the more bright you can find (i use blue but i've also tested with a white one), and a bit o cable, ah! and one "pusher" (don't know how to say in english, a thing that you press and it makes contact) like a button. I get it from an older toy.
I am not using a resistor but may be recomended.
A mini drill to make holes...

You can see it on the images. If you need any help or explanation about pics post it here and i will try to reply as soon as i can.
Feel free to convert your 3310 in a TLight!
Or if you would like you can use a UV light to detect fake € notes! :)

Hi,

Looks Cool!


Ps, we have same covers. :)

Very Nice!!

But I would suggest a 330 Ohm resistor to stop the LED blowing up ;P
Now I have a project to annoy my sister with she also has a 3200 with torch, hehe

Danny

@danwood
I have try with a resistor but then it doesn't light so much.

[mekme]

Very nice!

I builded for my 3210 a white led "torch" but i think i need a stepupdc-dc for it to glow perfectly. So for now i just use an 5cd RED instead. Its quite nice also.

If you calculate the right resistans. Your led will not "over-glow" and will glow like it should.

I dont know with an 3310 for sure but the max voltage is 3.6? 3.1?
And a blue with high mcd will probably like something with 3.8v and 20mA


One more thing...
Your button?, you press the cover to light it?

Take care!

[KetS]

@mekme
I have made a little hole for pressing the button but if you'd like you could add a kind of thiny plastic. But the easier way was madding a hole... :D

[mekme]

Hahaha!

Now i saw that picture.

Looks like you have "melted" the hole... And not drilled.

Funny thing =)

Have a great day

Hi,

My test on UV led. ;)

I suggest Dan is right bout the resistor.

Since mine is also blownup already. :(

Pity bout the UV, while it looked quite nice, for at least 15 minutes.

I still have a white led to go, is 330 ohm really ok?

NokDoc

[mekme]

Calculate right-resistans.
Vin-Vout
R = --------
A

Example.
Vin = 12
Vout = 3.8
A = 20mA = 0.02A

R = 8.2/0.02 = 410

Hi,

Thanks, good info.

One tiny bit of problem.

It's a bulb I got from a toy thing to check euros.

The only parameters I have for the formula are the 4 cells it had, saying it's supposed to be for 6V.

And my Nokia battery saying it's around 3.6V

How to know what current it uses?

NokDoc

[danwood76]

Well nokdoc if you dont have any clue to the values of the LED I would use a hit and miss approach as so:

Get a low value resistor like a 330 ohm and put it in series with the resistor if it is too dull then place a even lower value like 220 ohm or even 100

My assumption:

I would expect the LED is standard, most 5mm LEDs are the same values as there is not much need for variation.
I would guess it would be a 20 mA type as this is most common

At 3.6v I would suggest a 100 ohm is probably good for optimum brightness and no chance of blowing
But use the method above if in doubt

Below is a diagram of best way to join circuit :)

regards,
Danny ;)

Hi,

Thanks Dan.

I'll try those steps, and inform U, later.
