Hey everyone,
I'm working on a PHR-805T build in a 14500 host drivin with a benboost set to 190mA (if anyone suggests i run a lower current - please help me choose a resistor for it?).
I have recently realized that the benboost isn't very good with host-negative current regulation, while the PHR-805T diode is case negative. So my question is as follows:
Can I simply isolate my heatsink from the host (ie. black electrical tape), which will also isolate the diode and the benboost, but still leave the negative of my 14500 battery running through the host (from the clicky switch at the back end)?
If this isn't possible, can anyone suggest another take on this build? I've already ordered parts, but really I just wanna make it work
EDIT:
Found a resistor combo to get the benboost running at 100mA's - now I'm just asking about isolation the case negative diode
EDIT: Adding Pictures
Basic host parts - Clicky end cap with spring for battery negative, battery tube, head
Original flashlight electronic assembly
Assembled electronics (Ignore the cheap calipers - my good ones are in my room at school), comes to exacly 25mm when measured with the real ones too
Custom lathed heat sink (OD ~17mm, ID ~12mm, length ~24mm (left 1mm for the battery contact board at the end)
As described above (The contact board is a litle worn but I'll touch it up before putting it all together)
Host head (ID ~17mm, <0.5mm clearance against the host) - it IS anodized
Battery tube (with just an AA in there) and the host head + heatsink + battery contact board. You can see the manufacturer has grinded off the anodized edge on the battery tube to make contact with the board in the head
Thanks,
Nelly
