Re: Flaminpyro SS >1W 445nm Build (image heavy)

Wait a minute, I though we were talking about Cree C6 ...

Which host are we using ? It appears some very tiny host from that pill dimensions.

Sorry for not keeping track here.

Guys, I cannot figure out any possible way of construction that requires you to do what you are describing - spinning the heatsink and pill at same time , at same rate.

I mean, having 1 cm longer wires from driver to diode/heatsink (presumably driver is in the pill), and then unthreading the head apart to have the heatsink extrude from the head by that 1 cm, then threading the pill so the heatsink rotates freely in the air, after that, just push it back into the head and thread the retainer ring.

Or am I missing something here?

I can think of many ways to do it but it would require some machining. you could, for example, solder some tabs onto the edge of the heatsink that match into slots drilled out in the edge of the pill. they would line up and provide a mechanical connection that would allow both to turn with the other.

This could also be done with small set screws, threaded into the edge of the heatsink into matching slots in the pill.

this could also provide more mechanical connection between the heatsink and pill providing more heat dissipation.

i think there are many ways to make the jayrob kit better than the FP kit but as it is...

Here ya go. This is the host we are talking about.

Oh I see, epic host. Shineh

Jayrob, one suggestion -
You should machine the driver pill yourself, then drill a small hole in it, so you can install a set screw,
And make a heatsink with small extrusion below it, so it slides nicely into the pill , and then you can just tighten the little screw the secure it in place, and it's easy walk from there.

Or, make a contact board above the driver , and solder a spring as a connection to the diode, so the entire design would be similar to the "Aries" style lasers where such design, or it's variation, is implemented.

The pill has threads on it that screw into the head's matching threads inside it. The pill with the heatsink on top of it is inserted from the bottom of the SS Kit host head. When it is screwed up all the way the heatsink presses tight against the lip on the top of the SS kit head. If this makes sense.

If you look at the picture above... imagine there are two set screws in the rim of the pill, 180 degrees from each other (or maybe 3, 120 degrees from each other) with matching holes drilled into the edge of the heat sink. they would line up and allow the whole thing to be threaded into the host.

Frankly I think it should have been designed like this from the start. But that's just me.

I like the idea of something similar to this drawing posted by EnergyCoherence:

It would make it much easier to assembly without mistakes. Although mistakes could still be made if your not careful...

yes. of course. and i wouldn't have lost my flex drive in the process.

Well... maybe, maybe not...

But your acting like it was my fault that you killed your driver??

Not your fault, Jay. Im not blaming you. But I am annoyed that the design was so finicky and contributed to the death of the Flex Drive, that are no longer available.

I am more annoyed at Flaminpyro for selling me a faulty 445 LD, admitting that based on the evidence it was faulty, but not offering compensation suggesting I take it up with Casio or Nichia.

The point here was to build both your and his SH032 kits and do an apples to apples comparison for the benefit of the forum. So now i have a 445/1.5W and a 405/0.7W which is fine for my personal goals, but i also have $70 lost in dead electronics that was meant for the benefit of the forum (i had intended to convert one of the 445's to a 405 after I was done the testing and review and sell the extra 445).

Anyway, live and learn.

Well I'll tell you what...

Although I agree that there could be an easier way for the assembly (with my threaded pill style) if I did some extra work in design, I still think it is fine once you get the hang of how to assemble it... (or disassemble it)

But even though I did not sell you a 'Hot' option, and I do not take responsibility for an unfortunate mistake on your part, I still would like to offer a V5 FlexDrive if you are honestly trying to give some real comparisons for the benefit of the forum as you say...

This is because I am confident that my 'threaded pill contact to host design' is very comparable (if not better), for heat transfer to the host...

I spoke to drlava on 9/1, and he initiated a new batch order for the V5 FlexDrives that very day, right after our conversation. He said that it would take about a month for the assembly of the new batch.

So hopefully we will have them in a couple of weeks. I will obviously be stocking up on them for 'Hot' option kits and so forth.

I'll get one for you and send it to you...

I can't let go one of the ones I have on hand. Because they are all spoken for. (kit orders)

I do not normally even sell bare drivers. I use them for my 'Hot' option kits. That way they are installed and tested, with current set and lead wires soldered on ready for the buyer's diode...

The one I give you, will be a brand new driver, just as I get them from drlava.

In this case I will just give you a driver for the benefit of the forum, but if you have an accident with it, I will not be sending another...

Re: Flaminpyro SS >1W 445nm Build (image heavy)

Wow this is some thread, LMAO at someone wanting jayrob to do more machining and charge less for the end product. There's a formula for success.

IMHO the problem was not with the design of jayrobs heatsink/pill combo, but rather how the driver was or was not secured. When you insert the heatsink into the cap of the host the difference between the OD of the heatsink and the ID of the threads in the host don't seem to me to be more than a few thousandths of an inch. Once past the threads the amount of side to side movement that the heatsink has is at most just over 1mm, my point is if you mounted your driver securely in the center of the pill then the driver itself should not have been able to short to the heatsink or host, yes if the pill and heatsink did not turn as one unit you could twist the wires possibly breaking one of them and causing a short but that would take at least two or three full turns of the pill independent of the heatsink. I have read this entire thread carefully and all I saw written was that the driver shorted, nothing about a broken wire, that sounds to me like the driver was not secured other other than by the wiring. There's nothing wrong with that as long as solder connections were heatshrinked and driver was wrapped ??

In any case as jayrob mentions this assembly step as being difficult in his thread for this kit and offers advice on two different ways to do it, as a retailer he did his job. I just finished one of these kits the other day and also had problems with this step but knowing the importance of turning the two pieces in unison I found my own way and am very happy with jayrobs product. You can see my short review in the review section where I talk about this.

I see now that jayrob has offered a free replacement driver which just re-affirms what most of us on here think of him. I honestly think you should apologize and graciously accept his offer. I don't know how many of these 18650 SS kits jayrob has sold but I know its a lot and this is the first thread I've seen like this.

As for your beef with FP over the diode count me on your side on that one. I agree with you that he should at least share the cost of your loss especially considering your initial intention of doing a shootout between these builds.

Sorry for your losses plexus I feel for you and don't mean to be harsh but IMHO you were asking jayrob to take too much responsibility for something that if you read the 18650 SS thread you were forewarned about, just my $2.22 worth.

Re: Flaminpyro SS >1W 445nm Build (image heavy)

I'm also sorry for that loss on a now impossible to get flex V5. However I'm confused if it was the twisting motion or just comming to contact with the host that did the final damage.

I see that jay stepped up... good job.

I can also mention that if you were to send your driver to the very busy dr, he could repair that driver( might take a month or so). Maybe forward it back to jay when completed

@jayrob thanks for the offer. the only reason to convert the 405 back to a 445, with a flexdrive, is to do this comparison. so unless Flaminpyro is willing to address the defective 445 he sold me, there is no point in taking you up on your kind offer, jayrob.

I have already asked FP for a refund, exchange and even to meet me half way and supply a replacement at 1/2 price. he refused suggesting I speak to Casio or Nichia. so i am not going to ask him again - either he reads this and wants to participate in this or someone will suggest to him that he be as reasonable and responsive as you have been.

I feel my expenditure of around $500 for these two kits complete in order to do this comparison/shoot-out is enough. I am not going to buy another 445 just to do this. so there it is.

@jsyco as i posted, i did read jayrobs threads, read his instructions, and did a few trial runs without anything connected to ensure it was going to work. never the less, there was still damage due to the finesse required in the assembly.

Here is a video of a 280mW 532 being helped by the jayrob 405/07.W and flaminpyro 445/1.5W. watch in high def. for all you burning oriented people.

Lol that video was making me queezy, I love how aggressive the burning power is on the 2 last lasers :drool:

How could FP sell a faulty diode if it came straight out of a working projector?
