Ahhhh... they are in the circuit reverse-biased on purpose - my bad! :D

On a 1N400x diode, the stripe = the cathode. Cathode = negative Anode = positive The striped end = negative http://www.laserpointerforums.com/forums/YaBB.pl?num=1217284580 It seems to me all the graphics that represent a diode in that thread are backwards!

Re: Forward Voltage Characteristics of 1N400x Diod Yah, I should have said 1N4001 through 1N4007.

I was rifling thru the drawers at RS today, and I saw one of these: http://www.radioshack.com/product/index.jsp?productId=3004020 I wonder if it could be used somehow in a DIY laser power meter? Interesting!

Oh no! How did you ruin them?

I was reading the DIY Driver thread, and some other threads about building a test load, etc. today at work - and I knew I had various 1N400x diodes at home in my bug box. So, I did a bit of quick research, and I found out:  for our purposes, it doesn't matter if it's a 1N4001 or a 1N4007 -- for...

Who do we need to PM to get this stickied?

Re: Burning:  PHR-803T blu-ray vs LG 20x red Oh, I understand completely Ohm's Law and how to calculate electrical power - I learned it when we were still using E for voltage.  ;) Since (P=IE) =| optical power, I figured that electrical power was kind of irrelevant.  ;)

Still going strong - it's a Side Button Pocket Pal style build, using a Viclight and one of Jayrob's heatsinks.  Flexdrive powering it off 3 AAAs at 150mA. The diode is seated in the Aixiz module with Arctic Silver, and the joint between the Aixiz module and the heatsink is filled with Arctic...

http://www.arcticsilver.com/arctic_silver_thermal_adhesive.htm That stuff works great when you need to join two things together permanently and heat transfer is an issue.

The best rechargeable AA/AAA cells I've found to date are Maha Powerex. http://www.mahaenergy.com/store/Index.asp I bought the Wizard One Charger/Analyzer too -- it's a great tool for keeping all my AA/AAA NiMH cells in good shape.

Well said Gus. I feel the same way - children are just that: children. A lot of them I see these days seem to think they are entitled to adult-style treatment, and that just isn't gonna fly. Maturity is one thing, and I acknowledge that I've met some kids who I consider quite mature for their...

Re: Burning:  PHR-803T blu-ray vs LG 20x red I do not have a Laser Power Meter - so current is the only relevant known variable that I've got to go on.

Check out this thread: http://www.laserpointerforums.com/forums/YaBB.pl?num=1229552411 Now, I don't know how old Artix is, but that is EXACTLY how I imagine a teenager feeling & acting with a high powered laser. Excited, it's snowing, this is gonna be cool, etc. = bad judgment using the...

Thank you!
