First of all I have missed the builds where you needed to be somewhat careful on how you handle your diode:whistle:. Those of us who built PHRs or 2x-6x back when they were coming out remember how sensitive those can be compared to the ol M-140 or 9mm tanks.:gun: I know, I know there are some out now the 520nm and such, but I digress.:na:

I had a 4x sled sitting here for the longest time so I thought I would do a tutorial or build thread on what would a top dog 4x build would have looked like using some of the methods we have now copper modules, magic board. ect.

So I found a host from Harbor Freight as I typically look from time to time. I like to use those Gordons light for host in builds for our hobby.:san:;) Well I found a little jewl that I come to call simply the HF mini mag.

Yea it had like 30 LEDS no problem plucking them out though using good ol needle nose​

Back in the day we had to extract our own diodes I really loved this part of the build.

Here I used a speed variable Dremmel to cut a fine line out of the sleds heatsink to get to the diode. I also used the solder blob method to get the ribbon off:wave:

Then I pressed the 4x diode into the copper module soldered it up and did the doubled up the shrink rap on the pins for rigidity;).​

Time to turn down a heatsink... I had to use a 2" because the diameter of the head was in between the offered bar stock.​

I decided to go with a flexdrive V5 I thought it would complement the RHD magic board nicely.:rolleyes::drool: Here is the link for them over a cliffs store MAGIC board - $8.99 : Cajunlasers Store

I used Arctic thermal ceramic adhesive to mount the drivers under the heat sink and then set the current right about 150mA

Then finishing up with the diode hook-up remember to short the caps:whistle:

Then finally using a G-2 lens and a Moh lens nut I came up with a sweet little hand held. I plan on using this as a line of handhelds like I did with the sAiks as I feel that it has an ease of use and enough room to sink any diode we have now.

I used a 22500 battery in forward and backwards :drool: to come up with the results. Sure it's not burning holes thru plywood, but that wasn't the goal :whistle: just having fun doing what we do THAT was the goal.

Thanks for looking and get out and build. -jander6442

Awesome build tutorial Jander, Thank You! Very cool to see and hear more of the history behind the hobby :beer:

Hey thanks guys, this little jem did took no time to build. I had a blast going thru my build list and protocols I had a long lapse in builds and now I found a nice little host to dabble in. Now it's time to give DTR a ring.:whistle::san:
 
Nice work Jander! +1 Just curious why two drivers? The flex alone would easily suffice..:thinking:

BTW I know you said that people are building with less sensitive diodes now which makes things easier, but ironically the diodes I have killed have been an M140, 9 mm, 500 mits and a PL520 - Dont know what happened with this one was working perfectly then just stopped...!! :cryyy:

The ones I havent killed (some including extraction from sleds) have been of the more sensitive variety; an LPC815, a PHR803T an SO6J (rebuilt twice in different hosts!), Pl450B, a couple of 3.8 mm single mode reds and an IR...Ive also built several of the tougher diode lasers, but funnily enough only the hardy and expensive diodes have died! :( :beer:

Edit: Sorry must spread some...
