i received the dilda from olike..but...

hello. finally i received the dilda. susie gave me a true 195mw.....nut the laser seems not to be so bright ;(. i am going to be more precise.

the laser is powerfull... whtn i concentrate the light i can butrn matches.... melt  throught cd case...... but the beam is not so visible!!! i bought a 100mw laser at DX......but it was damaged.. it had not 100mw.... it didn't burn anything. i am waiting for the replacement that should be at my home between a week. bu..I REMEMBER.. that the luminosity is the same about! doh! the dilda has a better mrad.....in fact with an optimum mrad the point is VERY LITTLE also at distance....but it is not so bright!!!same as the (not true) 100mw pen sized(the case like newwish).

so... in my honest opinion i am not very satisfat of the dilda. i expected more...from this laser! MAYBE the cause of this low luminosity is that it has a 660nm ( deep red) and not a 650. it is impossible that an estimated 20/30mw red at 650mw looks about same ad 195mw at 660nm.

...the laser is a great burner until 1 meter.... ok.. but i think that its capabilty of burt is gave onlt from the FOCUSABLE LENSE. this is the most imposrant part. i am able to burn ONLY if the light is concentrated in a VERy....very..VERY..very little point! .

so.. i ask myself: how could burn a 100mw cni laser pen with a point of 1.5 or 2 mm???i thought that the dilda could burn also with a grater point(1.5 mm)but it is difficult or qite impossible.

CASUALTY, this evening i went in a fair electronics.... and i saw a seller with a 5mw green laser...and a 30mw green. WOW.........I was impressed :'(
i've never seen in the real life a green pointer.. but that 5mw looks to be MORE AND MORE visible of the dilda!!!..grrrrrr... ok i bought the dilda for its burning capability.. but i expected to have a powerfull red pointer.... but seeing a "stupid" 5mw to defeat my strong 195mw..... it is not very good.
green lasers are VERY VERY VERY more visible. someone told that the dilda is visible as a 30mw green....WHAAAAT? a 5mw green beats my dilda XD

This is normal.  Our eyes do NOT "see" everything equally.  Green light is right in the middle of our eyes ability to perceive light.  It takes very little green to look bright.  Red, however is at the edge of our ability to "see" it.  It takes MUCH more power in a red light to be able to "see" it well.


I'll trade you a 20mW green pointer for your Dilda. You won't be able to burn anything but your eyes with it, but you will be able to see it very easily

Peace,
dave

Here is another new Dilda owner..

@realista... wait for a foggy day and try your Dilda outside... you will be amazed


Jerry

in a foggy day is too easy......ehehehe. however.. could be the 660nm that makes it less bright?

ah... i ordered 2 cr2 at 3.6 volt! and i must say thay one cr2 that susie gave me is not very good. i test it with a meter.... and it is at 1.7 volt often on the end of life. i ma more precise. i chgarge the 2 battery.. ok.. i play..... but when the laser is diming.... i check the batteries with my meter. one is at 3.2 volt about.. and the second is at 1.7 about.... so there is a problem in ONE battery.. but ok.... i will have 3.6 v2 battery.. so these battery are not so important.

another thing i have to say. i wrote an email to susie. this email:
i don't understand your response on your site : it can charge CR2 3.6V as well as CR123.

this is what you says. but you ship 3volt cr2 battery... so.. i think the charger is specify for 3volt. and it cannot charge 3.6 volt. or jes?..

i don't understand so much. is in the charger a SWITCH that allows to charge ar 3 or 3.6 volt? if there is not s switch the charger can ONLY charge one kind of battery.... 3 or 3.6 and i suppose 3v.. because your battery are 3v....

R:
Pls kindly see attached photo .it is normal to charge 3.V ,but.take off the metal pad it will charge 3.6V batteries
-

i checked the voltage with my meter and the charger outputs precisely 3.58 volt.(3v battery). yes.. if a take off the metal pad it could charge cr123 batt..... but not 3.6 v battery!!!!(charged at 4.2).she could me more precise in the description.. this is NOT A REAL PROBLEM....but say at potential cusmomer that the charger charge 3v AND 3.6 v battery is a wrong affermation. maybe she would say that the charger charges at 3.6v..... but not 3.6v battery.. because they need around 4.2v

It's just for 3V CR2 and CR123 and has 3.6V charge output.

I have the same charger.... that charger can easily charge 3.0V CR2 batteries....
3.6V CR2 batteries and 3.6V CR123 Batteries... I have done this with all those battery types
using that same charger....

You would have seen right away that the power of your Dilda was nowhere near 200mW...
(because of your defective battery) if you had a Laser Power Meter... :

Suzie supplies 3.0V batteries because that is what the manufacturer of the Dilda
recommends... The charger CAN charge all 3 types of voltages and batteries
that I stated above...
And as we have seen on many Threads... the 3.6V CR2 batteries really do not harm the
Dilda while increasing the output power..

BTW.. you are not going to see (with the naked eye) the visual brightness difference
between two laser of the same output with one at 660nm and the other at 655nm..IMO

Jerry

how could you say that the charger can charge 3.6volt battery? i tested with a meter the current of the charger. it is ONLY near 3.6. and all people know that to charge a true 3.6volt battery there should be 4.2volt in the charger. i am not saying that you are a liars.... but f tha charger give out only 3.6... it is impossible to charge a 3.6 battery that needs 4.2 vold..... or i am wrong?

however by battery now seems to be normal. i have not noticed that problem of low voltage. all 2 bateries are at same voltage...i often check it
but the laser is not visible at night. only a bit visible. in daytime... no. i don'know how some people can say that the beam is visible as 20/30 mw green. and i am sure that the laser is at 195 because susie give me a true >190 she said 195. and because i am able to burn a match at about 2.5 meters. ...the laser has the power... but not the brightnes that i EXPECTED from a 200mw.it is bright as a 5mw green ....or lower

Correct me if I'm wrong, but I think that the proper way to charge a lithium cell is to increase the voltage drop accross the battery slowly. So if you want to see that the charger works with 3.6V batteries, stick a 3.6V battery in there and wait a while, then test the voltage.

ok. but i have never seen a charger that works for both voltage. maybe yes.. it exsist... but it HAS a switch power. there isn't an intelligent charger that can KNOW wjat kind of battery has inside and ghange at fly his output voltage.

You will NEVER SEE THAT BEAM in the day. PERIOD! 200mw is just not visible during the daytime and night you'll barely see it. Stop using beam visibility as an indication of power. I've got a 808nm 40 Watt laser that looks like a 100mw red. 40 Watts though will burn your skin. Its a LOT of power. So is 200mw.

Oh and the charger only needs 3.6v to charge a 3.6v battery. The belief that you need over the voltage to charge a battery is a falacy.

Look.... since you question everything we tell you.... then...

1) use the charger and 3.0V CR2 batteries that came with your Dilda to charge those 3.0volt batteries..

2) buy these 3.6V CR2 batteries and charger to charge the 3.6V batteries...

This way you will have the correct charger for the correct batteries and you won't need
to question every answer that we give you... to your questions...


Jerry

i have to do a SIMPLE question. is it trhe that 3v battery need to becharget at 3.6v? is it true that 3.6 v battery need to be charged at 4.2v? this is what i read on every thread in the net. i also seen 3v and 3.6 volt charger BUT thisk king of charger has a switch.  

i would only know the 2 questions......charger voltage of 3v and charger voltage of 3.6. kenom sayd that also a true outputting charger at 3.6 volt CAN charge 3.6 volt battery ( but this kind of battery is known to be at 4.2volt charged)

so... i feel crazy....disoriented. kenom has A LOT OF POST so he is a stusted member.. ok!but... all the thousand web pages that say that a charger for 3.6v battery charge them at 4.2.....is all false???

guys... excuse but  i would find the truth on this discussion. laserbbee.. i ordered 2 cr2 at 3.6 from that seller. and a lion charger from DX...i must wait to arrive at home

You will see that the charger that comes with the 3.6V batteries will put out
a little more voltage than the one for the 3.0V batteries... but the difference
is only a small fraction of a volt...

BTW... you should have ordered the 3.6V + Charger from the link I posted above... :-?
Those are the batteries and charger I used for all my Dilda tests and Threads... :

Jerry

About these chargers: I have a cheap one from DX that i use on both 3.0 and 3.6 volt cells - it was intended for the latter. So far, the unprotected 3.0v (CR2) cells charge fine in it with no sign of damage after serveral cycles.

Lithium cells can be very finicky sometimes, but for some reason it works out well.

while it is true that most chargers DO charge over voltage, it is NOT a requirement. In order to recharge you can either have a higher current or a higher voltage.

ok... thanks
