Hello everyone. I'm Phil, and I'm pretty sure I'm part moth. I was browsing youtube the other day when I came across a DIY video showing how to turn a green 5mw laser into a 100mw laser by heating a resistor on the laser. I was immediately hooked. I poked around some more until I found a link to these forums, and I've been lurking and reading for the past couple of days. I have to admit I'm pretty overwhelmed! I had no idea that laser technology was as developed and inexpensive as it now appears to be. I don't even know where to start! Well anyways, It's been a real treat to find a new home, and I hope to get started in the near future.
