It go with laser metal printer . One company shows us (they sells these printers ) a metal printed ( titan )
pump for nuclear plant . ( after print it was seriously X- rayed , ultrasonic inspected and tested on high pressure ... it works ) :) just different 3D printer
It is also good to have something for calibration
sensors are very sensitive to humidity, temperature and it is good to calibrate them regularly to...
not very good
- metal to metal design ( made it out of POM= delrin )
- with screws you will hurt anodised surface of lamps
- I see some brass on top of the screws ( galvanic series ) you can get these also with plastics
i like goodman's with some flat surface to avoid wobbling of lamps (...
if you go on smt code book (general search )

BSR 13 NPN SOT 23 switching transistor which have collector current only Ic= 0,8A ?
interesting : Diving Hookah Parts | AC Diving it looks they all have pistons
In my former job we made pistons for AC for cars . Clima compressors have very similar pistons and one directional valves made from steel sheat as I look on these sketches
Lumens output projected on surface with lot of luxes is not all . I have 4200lm but most stay on mode 2 with 1800 lum . I think with good lens or reflector is optimal somewhere near 2500lm light source . ( for simple solo or group diving )
All other is video light for illuminating the...
Can you drive light from power supply directly ?
Maybe battery pack wear out ? ( have voltage but have it capacity too? )
After many years in box I would cycle battery pack more times . ( Can you record charging/discharging cycle) ?
I think that there is desintegrating cable because of bad choice on cable . It should be silicone cable because it is soft and heat resistant ( could be also PTF but is usually stiffer )
Also is possble that friend uses higher voltage that means higher current and could be problem cable...
EX35 Primary Canister Light | Dive Rite
it looks that XHP35 HP in that light is at least equal or more to XHP70 :rofl3:
PS: HP is ''high power'' in way that is domeless and have narrower output angle . It can make tighter beam because of 15 deg lower output angle , but lens would uses that...
