Actual helmet parameters
Hello guys,
I am planning to build my new laser helmet with 300+ diodes, made as glass fiber cast following my head shape.
I have few questions, because i've been away from discussion for about two months.
What are the recommendations for best parameters of homemade laser helmet in this time?
Diodes? (still aixiz 650nm, 5mW?)
Diode spacing? (original OMG's gutter guard?)
Distance from the scalp?
Voltage?

Re: Actual helmet parameters
Diodes - Aixiz
Spacing - Gutterguard
Distance - 1-2cm. Better off just using brush bristles for uniform distance.
Voltage - Some say more but anything around 3.3V is best in my opinion. Just make sure you have something that will provide enough amps. This is more important.

Re: Actual helmet parameters
Im not too sure a fibre glass helmet work buddy.
I tried a fabric (small pile fleece beany hat) soaked in epoxy resin and streached over a pre-made mould.It worked fine-ish ,but when I had to drill holes in it it started to fall to peices.
It was really robust but the diode spacing is just too close to keep it solid.
I put loads of thought and time into the spacings,piloting the holes then final drilling but it was still no good.

Re: Actual helmet parameters
Also I just thought of this but if it is an exact molding of your scalp you won't get good spacing. Basically you want you mold to be in the shape of your head but bigger by 2-4cm. If you look at OMGs instructions he wears a winter hat or a towel when making the casting to make it a tad bigger than his actual head.

Re: Actual helmet parameters
Folks, how do you measure the amps? I have a voltmeter but I don't see a setting for AMPs.hapyman wrote:Diodes - Aixiz

Re: Actual helmet parameters
You can measure amps with certain digital multimeters but not all. Depends on your model, it should say in the instructions or try looking online.
Otherwise you can buy a specific device to measure amps.

Re: Actual helmet parameters
to hapyman:
Of course, I have prepared the gyps shape, which makes a uniform distance from my scalp about 15mm.
I tried those holes in fiber glass and there wasn't problem. If it will be, i could use another type of fiber or resin.
After building I will put some photos here.

Re: Actual helmet parameters
i also made a fiberglass helmet and it is great! you have to make a mould by wearing a bunch of hats or whatever... then cover up the second to last one with plastic so it doesn't get resin on it, then the last one is soaked with epoxy resin. (I think you would want to use epoxy because it is much less obnoxious smell wise than polyester or vinylester resin. The key thing is that is just a MOLD. You then have to let that cure on your head, then take off and cover with plastic so you can pull the helmet off later, and laminate with fiberglass and resin. So, NO you can not use the hat as your helmet. It is not very strong and i'm sure it would fall apart if you drilled a bunch of holes in it. My fiberglass shell is very strong and light though(stronger and lighter than a construction helmet) and I screwed the diodes into the holes I drilled. I put brush bristles in the top and foam on the sides and it has uniform spacing everywhere since it was taken from mold off my head and the bristles keep it at the proper height. I will try to attach a couple pictures.thSman wrote:Im not too sure a fibre glass helmet work buddy.

Cool Lukso, Keep us updated. Good Luck!
Looks pretty awesome hairisgood. That thing must look pretty cool lighted up That second pic looks like a trojan helmet.

Re: Actual helmet parameters
Oh I have a pic with it lit up too. Here it is. And a picture of my hairloss. I don't have extensive hairloss and have been losing hair for maybe 6 or 7 years slowly but not the diffuse aggressive type that bald people get. I can't even fathom losing 20-30 percent of my hair in 3 months like that poster said in another thread and blamed it on lasers. I think he is full of %&$!... that would mean in a year he would have no hair. Lasers seem to work for me but then again i don't have super aggressive hairloss and no family history of it.

Re: Actual helmet parameters
Your helmet looks great man - it's awesome to see all the different varieties people have come up with and the re-engineering that has occurred.
