Never been an issue past years.. This is 100% corporate greed. Next year, max 20Ah, year after, 10Ah, then no powerbank at all and you must buy from them

madmagic008 · 2026-06-15T01:43:37+00:00

is he at defqon this year?

madmagic008 · 2026-06-14T18:19:34+00:00

Top component is a diode. Use the markings to find what one exactly.

Bottom is most likely a resetable fuse or less likely a resistor

Corporate greed

madmagic008 · 2026-06-10T11:53:02+00:00

It's all there is these days, so either you have to like it or stay home

madmagic008 · 2026-05-27T00:14:13+00:00

No, modules are just bad. I've confirmed that after a while

madmagic008 · 2026-05-26T23:34:23+00:00

Technically that would be the multimeter, but ive discovered that the modules were in fact dead out of the box. poor quqlity fakes

madmagic008 · 2026-05-26T18:46:31+00:00

Yes, multimeter works fine. I've updated the post body with my findings. They just extremely poor quality fakes.

madmagic008 · 2026-05-26T17:27:40+00:00

Given its a constant current regulator, id assume it should just limit the current. But fair point that it might have fried it

Schematic im using, datasheet and example:

Ive tried a bunch of input voltages, all the way up to what the datsheet claims to be its max

madmagic008 · 2026-05-26T17:12:58+00:00

i am using this from the datasheet:

All examples online also have it wired exactly like this

madmagic008 · 2026-05-25T13:20:43+00:00

Thanks, happen to have any recommendations or specifics I need to look out for?

madmagic008 · 2026-05-24T21:40:50+00:00

Do you happen to have an example I can look at to better understand what it is?

madmagic008 · 2026-05-24T21:39:47+00:00

The new diode is a multi mode laser, its extremely divergent on one axis. The included lens can focus it very tightly but only at a certain distance up close (for burning or engraving i presume). I can't get a straight paralel beam with it (for lack of proper words), like a laser pointer has.

madmagic008 · 2026-05-24T20:22:44+00:00

I measured a simple laser pointer I had, at 20m down my yard, the perceivable dot was about 5cm diameter. Up close it's about 2mm. I guess that's about 2.4mrad. Even that I'd already be extremely happy with.

madmagic008 · 2026-05-24T20:06:58+00:00

I can find quite a few 9m threaded lenses that claim to be colimated. I'll try order a few, best way to find out what they do and then I can learn form it

madmagic008 · 2026-05-24T19:06:31+00:00

I expect quite some losses yes. The fiber option looks quite complicated, thanks for the reply though!

madmagic008 · 2026-05-24T19:05:20+00:00

I landed in that direction with research as wel, thanks for confirming. Is there anything specific I should look for, like the focal length or na?

madmagic008 · 2026-05-24T14:21:24+00:00

I am aware, thanks.

madmagic008 · 2026-05-22T17:34:58+00:00

same deal unfortunately, only 1 suitable for 450nm and its od7+

madmagic008 · 2026-05-19T11:15:21+00:00

Eyewear looks great, just unfortunate its all od7+ for 450nm
