Holy crap :wtf: Never heard this story, thanks for posting that tid bit.. 3hZo5k0V9M0

Well unless it was a mix up, I doubt you have the wrong lens.. I was thinking you may have purchased it from an ebay seller passing off cheap lenses but knowing the seller, that's not going to be the issue here. Have you tried any other lenses? The only thing I can think of is possible a...

Where did you get the lens? Looks almost like the stock kassio collimator, they produce a big stripe on each side of the beam. Just thought id throw that out there, in case it was purchased from an unknown..

Was going to post this in the fail thread, but thought is was perfect for this thread.. ejrEruna7oM :wtf: That has to be one of the creepiest coin operated machines ive ever seen.

I remember the incident of the sydney airport.. Was a few individuals with high class 3b greens targeting a single landing craft... The ban was very fast to be put in place. In the US and Canada, we have several occurrences annually, and some things have changed but nothing like what was...

Rusty provided some great guilt free laughs im sure.. I've worked with guys who just dont listen, its always fun to watch a co-worker who must learn the hard way :D Reminds me of this video, same thing was happening in Toronto, IIRC 4 times or so in the past few years.. Lifting their legs is...

July 1st Territory day?? You are mistaken, thats Canada Day :na: You guys got it pretty bad over there.. Here I had always assumed Canada was stricter than most.. Come to find out that a friend in the US cant buy any good fireworks (not all states), when it used to be the other way around, and...

I myself wonder how they get tracking for less than 5$, and why North American postal services honor this by updating it? Better service for overseas shippers and we pay the price with service cuts and inflated prices.. truly sucks. Im in Canada, and to ship to the USA, with tracking, cost me...

I picked up 2 589's here on the forum, both CNI, both not working.. I spoke to a rep there, and the communication left me uncertain.. One of the lasers was still under warranty, but decided against sending it back and figured id make a project out of them instead of risking the loss...

^^ Lightning.. you are the record holder for this thread :eek: I got bit by an old oil furnace transformer 10Kv @ 23mA. Left a tiny pinhole of a char mark where it leaped into my arm.. That pinhole sized burn later grew into a much larger scab and healed. Hurt like an SOB. Think I was 12 at...

For 18650's, its an easy one.. I got some nice Panasonic CGR cells from a dell laptop battery. No the best way, but when in need.... I abused the hell out of them, had a few on my nitro buggy, they all still work, and not one has gone nuclear :san:

I went to my local hobby shop and once asked for some 3.7v 16340's.. Guy looked at me like I was speaking Greek.. I have found none locally. So many people shop online for a fraction of the cost, no middleman and usually a declaration of 5$ value. Its the new 24/7 duty free shop :eg: I think...

Most likely boat containers to local distributors via freight companies. Funny though, I never realized there was a ban in place, yet I have never lost a package due to Li-ions, weather it was in or outbound packages. :thinking:

The range on that cannon is ridiculous.. He claims 2000ft IIRC, and the thing can pierce the hood of a car :eek: Bottle rockets :drool: I wish we had those on the shelves here.. I have lit a few in my time, but you cant just go out and buy some :cryyy: I think the confusion of the term...

A bit of overkill :eg: To go up in size a bit, I wouldnt mind trying this one.. SzL-yGcJG-w
