That's interesting. Edmund Scientific, Edmund Optics, and now Anchor Optics all have the same physical store address. I've always been satisfied with anything i purchased there with the exception of mechanical or optical items from their "surplus" bins that were obviously used as targets, both...

What was the digikey part number?

fast and cheap? 4 "AA" Battery Holder from radio shack Model: 270-391 cut apart it yields 2 springs with tails and 2 without at less than $.50 per spring.

My 2 cents worth would be as follows. for ir steal the flir camera out of the lockbox and run some focus settings per distance measurements so i could later mark the focus ring and host barrel with some form of corresponding graduations. 2nd experiment would be to try a small pinhole and ir...

If thats the price you feel I need to pay for attempting to pass on some common sense then so be it. It's a bargain compared to enduring a health issue or injury.

One for the road. http://www.completeza.com/Uploads/Ozone%20Safety%20Limits.pdf

Ozone Generators that are Sold as Air Cleaners | Indoor Air | US EPA Ozone Generator Hazards - InterNACHI Ozone air cleaners present a health hazard It's not that i have a strong aversion to your project. I just think that readers who try this should be knowledgeable enough beforehand so as...

A tremendous understatement. Try laying a piece of raw meat near to the ozone source and see how fast it starts to decay. At least include the warnings from the original instructables source. The dangers you must know...

Be advised. Current intensity and its expected clinical manifestation are outlined below: •1 mA - Not perceptible, probable tingling sensation •3-5 mA - "Let go" current for an average child •6-8 mA - "Let go" current for an average woman •7-9 mA - "Let go" current for an average man •16 mA -...

unless there was an error induced through an autoranging change, then it looks like the data points at and above 800 ma are skewed and never recover. after that linearity starts to droop with what would seem to be the effects of heating beginning right at 1000, but there's insufficient data to...

stumbled upon this after a keyword "exotic" search. all in all, very impressive. Those six jaw chucks are some serious business. That host reminds me of Luke's custom lightsabre. but i gotta give you +1 rep for that braided ribbon cable lanyard fob. Now that's real patience and concentration...

did you actually capture this data or quote it from somewhere? Either way, the readings after 700mA dont look kosher. it seems that a connection may have changed during this test before the heating effects started to become evident. and it wasnt a good idea at all to skip the 1100 mA reading. if...

addendum: before, during, or after which the diode may burn up, die prematurely, live a long life, or just plain stay darkened. choose one.

lol, thats more of a fusible link. it's a good thing you got that "wear goggles" disclaimer in your signature to avoid suits over catastrophic failures.

This is my first post to this forum after a fairly thorough lurking period. I have 2 nagging questions so far. Am I missing something or are you guys?? Why is there what seems to be a conspicuous absense of driver circuits based on the TPS63000-Q1 minimal component, high quality, high...
