Very good explanations in the video. Nice pick.

Mongolian Metal - The Hu I don't know about you but this makes me want to join the Mongol Empire and take over great chunks of land in Central Asia to Europe. Second video - if you don't have horses, you can always use a Harley. Ghengis Khaan motor bike gang! : ) This band was front and...

This is a bait question.

... What are you building?

Already posted by Trinh but I will post anyways - the link talks about drivers and diode Vf in greater detail. The driver will need to drive 2.4V which is the diodes nominal working voltage, more importantly you need constantly regulated current. try looking here...

If you were a little more clear as to exactly the project you were working on it would help us determine exactly which kind of supply you'd need. Thinking--- This may or may not be applicable in your case but.... if you making an arduino based measuring devices that uses one the ADCs or...

Very cool! I like multi-vapour lasers :)

I'd opt for something other than food grade mineral oil as your insulation as it will likely have moisture content. Something like shell diala ZX would be better for longer life and has superior dielectric properties. Mineral Oil can be heated up to 100C to drive off any moisture but do be...

Unknown.... but most likely yes.

There have been many videos showing the protesters using lasers to dazzle or blind police from both sides of the protest camp. The use of lasers to blind is violation under several international weapon conventions. Had the use of lasers like this happened in Canada or the US, use of deadly force...

Just got back last week from going to the Okanagan. My wife and Sister in law wanted to go to several wineries and swimming locations. Between localities I used my scintillation detector to go look for uranium and thorium hotspots . I was successful this trip and also discovered a locatity next...

Do not necropost on the form! The Air ionization thread was dead 2 years ago. Send a PM and ask if you are still unsure instead of reviving a dead thread like this. Please see forum rules and forum edicate.

Go back and look at the thread content. Read the responses. Necroposting is STRONGLY discouraged on the form.

Well it's been nearly a year since I was last posting anything significant on the forum. Anyways... I just came back from a trip to Quadra Island. Geologically it is very unusual. Several localities on the island are rich in Copper, Iron, Antimony and Tellurium. I went to several...

Obviously I agree. Sometimes you have to burn yourself to discover something is hot. If you injure someone else, that is where I'd draw the line.

For those who are talking about this project in a negative way. Everything in this world has risks. “The person who risks nothing, does nothing, has nothing, is nothing, and becomes nothing. He may avoid suffering and sorrow, but he simply cannot. learn, feel, change, grow or love. Chained...

Good information. btw, have any of you had a chance to look at the 21700 sized cells yet?

right.. that's where I was going next. Got to make sure the cells are the same by testing them. Though the 21700s look like an easier find.

Something that would take multiple smaller li-ion cells for upping the current.
