Yeah Mojo, why do you care? I must say I'm glad to see someone new to the hobby start out with a 5mW pointer for once and be completely content with it and willing to learn about safety. It's far more common and irritating to see a thread titled "how do I make a blue laser that can burn?", as...

Nice phasing! Yeah I've done that with 3 12/60s, arcs were insane! I'm in the process of a making a better inductive ballast for my pole pig and then I'll be cookin with 14.4kv at over half and amp! :eg: Sure you can. I've used just a screw driver as a chicken stick. But that's not such a...

I've never liked Benchmade. To be honest they have very few knives that appeal to me. I'm really picky about how a knife should look and what materials it's made out of. Plus they're ridiculously overpriced. Even their cheaper knives are so expensive that you wouldn't want to use them. That's...

Guys try Gravilux! It's freaking awesome! It's like a gravity simulator that allows you to maneuver little stars around in different patterns. It's not technically a game but it's certainly entertaining and it's my fav app so far! -Tony

When I first came to this forum in 08 everyone HATED Wicked with a passion. Then some time went buy and I took a break from this place for a few months. I came back to find that people all of a sudden favored Wicked and a few pretty good reviews of their lasers turn up. But ever since the...

I usually read that using MOTs is a bad idea for a jacobs ladder, but if you can get the V set up right to work with just 4kv then go for it. They certainly have the current to pull out the arc! -Tony

LOL, Anyone wanna be Moe? :na: Yeah be careful with HV! I've been bitten by an NST before, thankfully only on one hand, and it SUCKS! Make sure you UNPLUG the thing before you go near it. Don't trust your life to a switch. You're correct NSTs will not hold a charge (Unlike my ZVS driver)...

Uhh... just run it off 3.7v Are you under the impression that if you increase the voltage then the laser's output power will increase? That's not the case. -Tony

There are other reasons you should take into consideration when setting the diode current rather than just the capabilities of the diode. Personally I'm more worried about the driver. The efficiency, at best, of the Flex or Boost Drives is about 90-95% which may seem pretty good. But think...

I'd agree with udanis; 200-300mW. The brightest green laser I have is about 150mW (on a good day) and it isn't nearly as bright as my 925mW 445nm laser. Our eyes only perceive 445nm about 30-40% as bright relative to the green light peak. So you can crudly equate them by: .3 X (mW of 445nm) =...

I wonder if 405nm is capable of killing any bacteria that might have been in the drink. I bet to a certain degree it does. -Tony

Yeah I agree that the laser is heating the liquid. Florescent objects absorb much of UV light. But I wouldn't drink it, oh not because of the laser, that crap is terrible for your teeth. :p -Tony

I think if you mention to them what it is, the moment they hear "laser" they won't want it on the plane. Those who are unfamiliar with lasers immediately shun them away as "dangerous". The average person believes a dinky 5mW red pen laser can blind them instantly and give them cancer. Don't...

I know what you mean man, I'm right there with you. There are sooo many things on my "want" list right now. But there is only so much I can afford as a poor college student ATM. :undecided: See if you can track down a couple of used PC power supplies for cheap. 24v dc will get you decent sparks...

ZVS means Zero Voltage Switching. When the mosfets trigger there is no voltage across them, that's why they stay so cool and the circuit is so efficient. It's also know as a Mazilli Driver, or Current Fed Parallel Resonant CFPR driver. TJ, I'd say invest in a nice DC power supply or variac...

K here is a video of my three Jacob's Ladders. I have them running off my variac because it has a fuse to protect my house mains circuit in case something were to happen. Sorry for the fuzzy pics. I took them with my phone. The first one in the video is my automotive ignition coil based...

^Good point! But IMO your average DDM is more than capable of measuring the resistance to within a few percent which is much better than not measuring at all. Like you said if you're calculating resistance with miliohm precision then other factors like parasitic resistance come into play. Hell...

I go to this Fry's all the time! I have see those things run too! Behind each pillar is a door that conceals a pole pig. I saw it once while they were doing some maintenance on them. I've made three different kids of Jacobs ladders in the past. One form just a NST, another with a automotive...

In my experience I have used a C-clamp successfully but it's VERY difficult to center the diode level in the module. The beam will come out crooked. If you roll the completed laser on a table while it's on you see that the beam traces circles on the wall. If you have, or have access to, a...

This is why I like this forum. :D -Tony
