I'm still around !!! At 72, I have slowed a bit but I still play with my toys. My left eye was damaged in cataract surgery and I can't see to solder well any more and had to sell my plane but I survived covid easily !!! It's hard to believe - almost 14 years !
Carry on dudes !!!
That lens module simply would not go into the heat sink. It acted like it was cross threading. Other lens
assemblies fit right in and the G8 lens fit my other heat sinks.
I noticed that the lens is farther from the diode in my 2 watt but it has plenty of threads and it works...
Jordon -- I got a G8 lens some time back. The lens would not fit your Cu housing for my blue Phaser gun.
Today, I put it in a 2W blue pointer and WOW does it make a difference.
I will buy another if it fits the Cu heat sink in my Phaser. Can this G8 glass be transferred to a different housing...
That's why I clamped my TI PS to a voltage which under "normal" conditions
would provide 30 Amps for test purposes. If the FAP decided to suddenly draw
85 Amps at a voltage which can provide only 30 Amps, Something went WAY wrong.
I picked the 50 Amp module so it would be running at 80% at full 40 Amp module rating. Sometime, I may want to try
the FAP at rated 40 Amps. It is unlikely a massive module failure could draw 85 Amps and if it did, the FAP was
trashed anyway. The other failure would be an external short which...
I'll try posting my pix again. The Bottom pix is the FAP with TI driver. The cells are under. The other pix is my
schematic for the TI PS. I'm using the Fiber optic cable to blur the dots in the beam.
That 50 Amp current supply regulated on the (-) side which might be good since...
Hey Desert guy! I can't find my schematic I drew up - But - I downloaded pages 3 & 4 of the data sheet.
It sorta come back. Remember, this is a "stable voltage" regulator.
1. Pins 4 & 18 set the max voltage output. I forget the module voltage for 40 Watts.
2. Here's the magic ---- Pin 20...
I am using the TI PTH08T250 supply. It is rated for 50 Amps but I've limited it to 30 Amp MAX for now.
I am using 3 18650-25R cells to light it up but I can regulate the current from 0 to 30 Amps with a small pot.
For basic lens testing, I run it just above threshold because my cooling is...
