Hi everyone,
I'm Koen, 24 years old and student Maritime engineering. I'm also busy with photography and 3D printing and I did my Padi OW course last october. Now I'm waiting for the water to get warmer again because the water here in the Netherlands is a little chilly in a wetsuit right now. I don't have a complete set yet but it''s growing piece by piece already. Eventually I'm planning on taking a camera with me when I have more experience.
This week I fixed a Magicshine diving torch (MJ-810E) I got from a friend who didn't feel the urge to repair/fix it because he had a new (better) dive torch already. The problem is that the charger was broken and the battery had also died. Note that there is a 'special' battery inside the MJ-810E where the + and - are on one end but it still has 2x18650's inside. So it's a pretty standard size, just annoying they put both poles on one end.
Luckily I have a technical background and a 3D-printer at home. So I drew and printed a battery adapter for 2 18650 li-ion batteries (which where inside the original battery too, so same voltage, just different capacity) and made 2 little PCB's which are connected from one end to another to replicate the + and - on one end. The result of this battery adapter can be seen in the images.
A lot more convenient because I can now use regular 18650 batteries, and I can charge them with a standard charger.
So after a day of work I had a fancy battery adapter and a working dive torch because of that
.
If you have any other questions or want to know more about me, just ask.
Kind regards,
Koen
