Dear friends, I am in VR-China (Zhanjiang) now. I can buy almost everything here, but no laserpointers at all. Seems they are produced only for foreigners...

About the first wf-139 I remember it is no difference in charging time. One cell or two cells, same time. But I did not use it for 2 years and also never put attention on this behavior as I used it mostly for single cells. About the second Wf-139, I think its somehow different. I did not...

My charger which was included with the Susie´s pointer became strange suddenly. The LED is red now without battery, but if I insert the battery it becomes green.... I guess it´s broken, because the cell stays suspiciously cold. I have also two WF-139 chargers from DX, the first one charges...

Yes, its the same with my charger. After inspection I found, at least at my charger, that the fault it the soft minus sided contact. The internal spring is so strong, that the thin metal minus side bends back while inserting the 18650. Only solution is to bend it back to the plus direction by...

Re: O-like 400mw green - Review ZapU, thank you for the great pics. As for the uncentered looking lens, this is quite the normal case, even with labaratory lasers I saw this. From outside it looks uncentered, but they are still centered optically. Are you sure, the beam has a better shape now...

Thanks for sharing your experience. I think the 14500 normally should be able to handle the required amperage, so probably it was retired or not charged. (the printing "3,6V" actually means a nominal value, like "12V" on your car´s battery. The "12V" actually will be somewhere at 13,8V when the...

Re: O-like 400mw green - Review If this is really the case with yours, then there are different models out there. But I think it would be a very uncommon way, because the lens needs to be flat towards the waters surface, otherwise it would not be focussed underwater anymore. Today I wanted to...

Great chart, thanks a lot. Also I encountered lots of mode hopping, it starts right after turning it on, keeps wild for half a second and then calms down... I guess we have to live with it, considering it was only 209 dollars.

Re: O-like 400mw green - Review So, mine arrived yesterday. It came in a small package together with the microcharger and a flat headed Ultrafire 2400, which does not give a well contact because of the flat head. So I exchanged for another 18650 from my shelf and everything is all right. I was...

Re: O-like 400mw green - $214 (hitting 600mw) - Review Today I looked at o-like´s homepage again, and I did not find this pointer anymore...

Re: O-like 400mw green - $214 (hitting 600mw) - Review I am selfemployed in the cleaning business. Sometimes it´s a day and night job. I know my attitude is not good for my health, Thats the reason I am here now...:beer:

Re: O-like 400mw green - $214 (hitting 600mw) - Review I am busy the whole day and every day. So mostly I don´t care too much if I have to wait days or months for these things. In rare cases even if it arrives I need weeks to find time to even open the package, because urgent things are...

The 14500 then I will do as an own project when I ever should find time to do so. So its not that important right now. Yesterday I took a flat headed screwdriver to fix the lens. I accidentally screwed it in too far (there was not a lot of force needed), with the result that I could not focus...

Sorry for posting into this old tread, but this really belongs exactly here. Per my own measurements these laser pointer modules start lasing at full power if you feed them 2.5 Volts or more. Below 2,5V they start becoming weaker until they stop lasing at about 2V. If you supply a voltage over...

Ash, thank you. You are absolutely right, now I wonder why I did not see this by myself before. I guess I am becoming old. About the white stuff around the lens-system of your pointers head, it looks like glue. Did you put it on? My pointer does not have any glue or similar at that place. Now I...

Re: O-like 400mw green - $214 (hitting 600mw) - Review Also I got the email. The pointer is shipped. Now I have to wait some weeks (months?) until arrival... Shadowspawn: What the hell are you doing in Japan these days? Family? Druid: Thank you for giving this option. If my order were not...

Anybody of you guys got one with a loose lens? I noticed that the focus changes by itself if I turn the whole pointer (around its axis), then I found one lens is shaky. Now I need to buy a tool to open the top to get access to the lens. I don´t want to send it back because such a minor flaw...

Thank you for your warm welcoming me! I am happy to be here. As soon as I find some time, I will post about my past and recent humble projects. One of them will be my try to repair (and possibly increase of power by using a stronger pump diode) of a 500mW 532nm labby which could also result in...

Thank you for welcoming me! Anselm: Danke! Ich bin selber gespannt! means: Thank you, I am excitingly looking forward by myself....

Dear friends, I just read this, because also I am a new member. Thanks for the suggested rules. I want to post some of my thoughts to what I read in this tread, so please don´t take it too serious To the vets: Yes, new members should not argue with you. But sometimes they maybe did not...
