Please Help me decide  !!! ( pics inside )

Hello all, ive put together 2 phr 803 builds with your not so tipical host
1rst was with a airsoft laser sight module that is adjustable , and its
a rather strange looking thing that has a ddl driver i put together ,and 9v
battery.

Heres a pic of 1rst build.


Im rather happy with this crazy looking thing , but im having issues with
this second build.


Second Build
This one is made out of copper 3/4 tubbing!
Im using aixiz module and a ddl driver i put together, running it off cr123 bateries
.It works great but im concerned that it might overheat and die.
There is no heatsink and  had trouble with the + and - connections onto my
driver. the whole host is + polarity and i dont know if i heatsink the aixiz module
if there will be a problem since the host is +.

also im running the driver and im using a the  lm317t ,100ohm pot,12ohm resistor  witch put out prety good power but i dont have the parts to make
dummy load thus not knowing the exact ma its putting out.

-Main goal and  concern is heat and power .

-What should i do , change host ? if so witch one ?

-I was thinking maybe project box with cpu or other modded heatsink
and a heatsinked DDL driver and different battery. what do you think, based on goal what do you guys  recomend?


Heres a pic of the 2nd build...

Hey.... the copper tubing build is original and neat... Thumbs Up..

If the Aixiz module makes good contact with the Copper case... I wouldn't
worry about heat build-up.

If the electrical polarity is a problem to transfer heat from the module to the copper
host... think about using silicone heat transfer pads... like are used to electrically
isolate transitors fron their heat sinks...

The PHR diode has floating pins. It doesn't use the can pin. This means you can easily heatsink the AixiZ to the host. In fact you should. Try to make a heatsink that will have good contact with the module and the host, so you make the entire host a heatsink.

It will work very well. Thanks god for floating pins, eh?


I really like the apperture on the first build. That's from a laser sight from an Airsoft gun? Looks great! Good job.

Do you have any pictures showing the sight itself?

Thanks IgorT for the reply, thank god for floating pins , i will be making heatsink of somesorts.


As for the first build i do have pics i might post them tomorrow
