No, do not be confused by colours. It was 2 pieces of the 4 coloured wires cable for color LEDs, which were easy to solder together into contacts making them parallel. One 4 coloured cable was +, another was - in my case. Yes, better stop receiving things until epidemy is over. Here in Spain it...

Hi, I do not get why do you want to reduce distance. It does not make sense to use those cylindricals for tightly packed multibeam like from 31T and for correction of single MM beams from NUBM44/0708 we need at least 6x or better 10-12x expansion to have a round spot at high distances. All this...

This is what I have left from this array. I dismantled it afterwards to take front surface mirrors. But here you at last can see how the polarities were oriented in the ribbon.

The point was that the sellers of these sets in ebay do not specify any expansion ratio (what if f1/f2) but only so called "width reduction" =3x what means the reduction of spot width (no idea at which distance !!!) compared to spot width without cylindricals. To know the real expansion ratio...

Hi, Eddie I do not think that you could make a good cutter fom A-141 array because the knife-edged beams which come out of this light engine are not very parallel. However, couple of years ago I have burnt wood and other things when putting in the focus of the lens which was built in. I...

Hi Farbe2, I would also like to see a picture of the multi beam profile. Could you please make a picture of the spot from this array on the wall through OD6 googles at let us say 1 and 5m distance passing low current through each row. 0.3-0.5A would be enough I think. Like I did in my studies...

I would stop buying things (except masks and sterilizers) until infection wave is over or at least starts to go down. If delivery services are halted postages can be lost somewhere.

Hi Bob, I saw it and I even ordered some of these radar bodies to check how big they are. However, I do not know where they would arrive because our Campus is now closed for 2 weeks (or more?) quarantaine and there is no one at goods reception any more. It is good that Styro shows the inside...

Hi Serveurperso, Do you live in Paris? Until 2008 I worked in Atofina company in Verneuil en Halatte (Oise). Not far from Paris. DTR just answered to my inquiry and yes, you are right. He sent me v5 press style heads by mistake. He would send the replacement but maybe I will have to polish it...

Hi Serveurperso, Me too received 5 of these no press modules from DTR and in my case I cannot fit GH04W10A2GC into them. However, they fit into Lasertack Al and plated Cu mouts well. I think the reason must be that his supplier did not produce him the 1st lot acc. to design and kept some...

Ha, you are using same words what I have used to ask styro, DashApple and other members who bought 31T to post a spot picture! Not yet there. Even for one row I would make a proper HS+driver set up.

Well done, styro! Finally the YT video! But: you again do not give any info about spot at large distances. No spot picture throgh googles at low power, not even a hint how big this radar body is. As far as I can guess, the diameter of Al cylinder is 80mm and a bigger one would not enter, is...

Styro purchased his 31T in summer and did not yet post any spot picture. Then DashApple... And from me you guys want to power all assembled just a little over a month after receiving the bare chip without any specs info available? This does not work so fast! Up to now I found right contacts...

I picked it exactly because it is not 31T. Something different and cheaper. And I want to check it because no one will report me about these tolerances before I check them by myself.

Hi, I do not know what kind of phosphor you have but when I dismantled projectors I tried to make green light by putting phosphor wheel (one like you can find in ebay) into the focus of KE-block (I think it was one from M130). So less than 50W for sure and pretty badly focused by the end lens...

Does anyone know what it is? I mean this set...

Guys, please do not hurry, wait a little more. Not everyone can check LPF every day. Especially mgould who has written 11 messages since 2011. Private mails can help. Me too, when on holidays try not to touch internet for couple of weeks. Not because there is no coverage but just to take a...

Thank you, Bob, for organizing this! PP sent. We were waiting for this to happen since august, now I think we are able to wait a couple of months more for the process to accomplish!

Thank you, I did not know about those votage regulators. Instruction says that all the voltage difference goes into heat - so this transistor might need a HS, right? Or better in a module...

Right desinfection needs strength, not price. Here is my favorite medical sterilizer, I still keep one bottle brought from Dublin years ago just for the case. And these things were traditionally made of potatoes if this is an important point...
