All I could think of was that movie were the bug goes in this guys ear, they tie him to the bed, he freaks out for hours, then it comes out and the doctor tells him it laid eggs in his head, LOL.

My friend had a moth fly in his ear. The stupid idiot stuck a screwdriver in his ear to get it out, and he lodged it in there. He ended up going to the hospital.

How does the screwdriver get stuck? Or was it just painful to pull out?

LMFAO. Man, get some bug spray.

I got a baby roach in my ear once. I was around 13, and freaked hard. I could hear it scraping my ear drum. My brother was passed out drunk, and I couldn't wake him up to bring me to the hospital. I ended up pouring alcohol in my ear. It finally died and fell out.

I know how painful that can be. Back in 1984 I was mixing a live show at an outdoor festival. The act at the time was a troupe of girl dancers (in between bands) and I had to cue each track on a Revox real-to-teal tape machine (one tape per track). During one of the dance tracks a moth flew in to my right ear, I fell the the ground with the pain as it fluttered hard against my ear drum. I remember the ambulance crew dragging me away as the tape machine de-spooled and the dance group stood on stage thinking WTF!

In the end they drowned the moth by filling my ear with fluid, then they removed it with tweezers. When I got up to return to the gig I could hardly walk I was that exhausted from fighting the pain.

The festival was a multicultural event (Greek, Italian etc). I recall the ambulance guy looking in my ear and joking "it's a flying zucchini!".

Let's see how off-topic we can take this thread... :crackup:

I see its a common problem. :crackup::crackup::crackup:

DTR, the moth lodged in his ear. Sorry, I have a problem assuming people know what I'm talking about all the time.

I need one of those. If it could take a woman's blabbering and turn it into small, short sentences, It would be worth a billion dollars. :yh:

I am afraid it is only a translator. It can translate Vogon poetry (although not recommended) and a thousand other alien dialects. Converting senseless dribble in to sensible English is however beyond it's capabilities...

I don't know why but this thread got me thinking. Can you put a high power laser through a large fiber optic cable?

Yes, but you need to couple directly diodes and fibers ..... in IR "bricks", this is done usually placing the fiber in front of the emitter chips, for canned diodes i think there are fiber couplers that include the needed optics, but i doubt that they are available with 445nm AR coaring (they are usually made for IR too)



Some of those 40W CO2 laser use fiber

Yes, but the fibers used for CO2 are totally differents from the ones used for other wavelenghts ..... 10600nm is adsorbed from almost all the materials that can be used for make fibers, so they have used a completely different principle ..... the "normal" fibers are like "bars" of glass, where the light bounce inside the "core" material, on the fiber walls, made around the core with a material that have a different optical index ..... CO2 fibers, instead, are literally "light pipes", they are made using layers deposition, alternating dielectric mirror layers of the same wavelenght thickness, so they made a hollow tube, that have the internal that is an almost perfect mirror for the 10500nm light (i think the last results was 99,98% reflection, or better), so the photons literally bounce inside from the input to the output ..... and in the hollow space inside the fiber, together with the light, also flow the cooling gas for avoid heat damages .....

*Back to the spider topic*
I would have squashed "Boris"
Spiders often wander over and bite/feed off of you at night.
I was getting red marks on my hand that weren't going away a few months ago. Turns out they were spider bites and they weren't going away because the little bastard kept biting me every night.
I like the jumping spiders too but if they are in the house, they die.
One also ran up my nose one time when my gf tried to brush it off....
I was amazed at how much fluid can come out of your nose when there is a spider running around in there. :eek:


I've never heard of a spider that feeds on humans because they don't. Their physiology is not setup for it for a start. They digest their food externally. Being bitten by a spider in your sleep is not an act of predation by the spider but one of defense. I highly doubt that the bites you endured were actually from a spider at all, as you say you bitten repeatedly, and more likely one of the more common nocturnal insect carnivores. In fact, and with more than a little irony, leaving the spiders alone may actually have reduced the number of bites you suffered.

Ahh, the Babel fish... Proof that God exists at last! ;)

Factoring the cost of a 'launch' system with coated optics,
id say this would be the cheapest and least complicated.

In this pic its a cmount 1W 850nm. Probably the simplest
arrangement to DIY..

Hey XX, you might have bed bugs. I read there is a huge re-infestation going on. It said a lot of foreigners were bringing them in, and were infesting hotel/motel rooms. At night they creep in your luggage, and you bring them home. There are tell tell signs. You should check it out. Would explain why there were so many spiders too.

I think Casio has more "real-estate" on their boards for complicated drivers with all sorts of feedback and sensors and stuff. What we have to work with is much simpler, but that means that failure, while more predictable, is liable to blow one or more components.

I bet you could get a microboost to drive a few diodes in series if you had enough volts to supply.

Sorry TJ, getting on topic.

I doubt you'd fry the entire string if one LED--er laser diode--goes. They're not like strings of Christmas lights where frying one light ends up affecting the others. Look at what happens when you fry any diode: does it suddenly start passing extra current? Does the voltage drop change? Probably not. It just destroys the reflector on the end of the diode, and the laser diode acts like its old self, only without its front reflector.

You'd also be using a constant current supply. It'd only be adjusting the output voltage as needed, and it shouldn't change for the diode string.

^ it depend ..... they are series strings, like the christmas light ..... if the diode jus LED, but still act as a diode, nothing too much happens, all the others still works ..... if the diode short circuit, the string "lost" 4V of dropout voltage, and the driver can notice it and stop all ..... if the diode goes open circuit, the whole string stop to work, and also in this case, the driver notice it and stop the projector .....

Difficult that you fry the string, anyway, cause the checking circuit on the driver acts in less than half second, usually ..... only case that i can imagine, for fry the string, is if the diode "melt" something, going opened, and suddenly going back shorted, in 1/10 of second ..... in this case, the string get disconnected, and then immediately reconnectrd on the driver output, that in the interval increased the current ..... but i think is really rare, as problem .....


EDIT: also, those diodes are insanely robusts ..... i have one working at 1,2A, and for a mistake, i reverted it (positive on negative and negative on positive) ..... this usually means "instant death" ..... other than this, i turned it on and off 3 times, for some seconds, when i noticed it was not working, before notice my mistake ..... i was thinking i wasted the diode, but wanted to check it the same, and reconnected it right ..... and it still work perfectly, no strange or dark zones in the beam, and still the same power as before ..... i think i can call it "the miracled one" :p ..... also, if you remember, i had one of my first diodes in a "torture chamber" for see if there was some degradations, in the long time ..... initially, i had planned to get the data and post them here, but there's no "degradation data" to post, yet ..... the diode is working continuously at 1,6A, 10 seconds on / 10 seconds off, from 30/06/2010, 24/7, and til now it showed no power degradation at all ..... i'm wondering how much it can go, at this rate
