Stpuid Mistakes?

Well, recently about 2 month ago, you guys may remember that I had hit a dry spell where all of the diodes that I touched died with in 45 min.

All together, I managed to kill...
3x SF-AW210 = to $145
1x PHR-803T = to $16
2x LPC-815 = to $25
2x Flex V4 = to $60

I don't know what had happened to me, but either way, I am now back to building good lasers again.

Later,
Iskor12

I accidentally... the laser.

How do you get 3,300 post and only 4 pointers? Oh I see none have died gotcha

Well the only 4 pointers is because I can't afford more.I have a lot of laser stuff on the wishlist but I don't really have the money.And I have 3300 posts because I participated in a lot of serious intelligent discutions (and when you add the 85% spam posts lol....)

But considering that I haven't messed up anything, even if they're not many, it's still a 0% mess up ratio.I guess you're more careful when you can't afford replacements lol...

OMG, I just killed an LPC because I over thightened the back potion of the aixiz, I broke the solder connections driver/diode, and because I soldered back the driver without discharging the cap, it's no brighter than a 1mW...
:cryyy: :cryyy: :cryyy:

you know whats worse than making a stupid mistake? making it, and never finding an answer for the mistake. I made, and killed 3 phr's in a row. still don't have a clue how. The driver is fine (it's in another build right now), the batts were 9v alkalines (new for each build). ESD, I doubt it. They each ran for 5-10 mins be for going led on me. each burned for a short while each had a slightly visible beam and none ever got mor that 120 ma. :banghead::banghead::banghead:

Were they killed on the breadboard and did you use a power switch, or already inside the host?

I have killed many Diodes while testing them on the breadboard without a power switch.:banghead:

thats my problem...

i was using the rkcstr driver.

About diodes, i zapped a 20mW red one, and a pair of IR harvested from cd burners ..... and cooked a bit a violet one, when i forgot to check for temp. running it at 110mA for long time ..... also cooked a red one, the ones from phr803, thinking it was a good diode, i supplied it with 70ma, and it quickly gone

About gas ones, i destroyed the mirrors of an old 5mW he-ne, connecting it for error to the power supply of a 100mW Spectra Phisics one ..... he not agreed the 12Kv and quickly died (and the resulting semi-short killed also the psu, so now the 100mW unit is collecting dust in magazine too )

Ah, well .....

my list of stupidity goes on without bounds. Now I've not killed a powerful one like into the Watt range, but my diode graveyard is enough to fill one of those small bathroom garbages. (Easily 500 diodes)

Some from stupid things like breaking off pins while pressing them into aixiz modules or Kryton heads. Some from ESD or from not turning off my bench psu before hooking them up and killing them with spikes. Some from just plain stupidity in extraction where the die ended up coming out of the diode because the diode itself got twisted and mishaped.

I kind of dread getting my newer diodes (30W fiber coupled) as I'm afraid of topping the other high power kill.
