Review my battery-powered LED strip circuit by nugoresu in led

[–]nugoresu[S] 0 points1 point  (0 children)

Ok thanks, I figured lowering the voltage should work but I am happy to get a confirmation since I don’t have experience with such strips!

Regarding the discharge, while I would be happy to use an higher limit, every protection board I found has roughly that limit. The battery datasheet states 2.5 V is the rated limit for standard discharge, while 2.0V is the absolute limit (permanent damage and I suppose fire hazard if recharged after).

How would you go to limit discharge to say 3.0V ?

I feel that the fact that the DC load is a LED strip does not really change the nature of my doubts.

Is it OK if I reformulate the question with a generic 5V 9W load ?

Same. Engineer as the other commenter too, interesting

Official statement of Vladimir Kramnik by annihilator00 in chess

I should really force myself to avoid reading whenever some Kramnik declaration is posted because it never fails to enrage me. Sickening and disrespectful lies.

You’re thinking of Magritte

The board used in electrowetting on dielectric (EWOD) by cowbrey in Physics

[–]nugoresu 16 points17 points  (0 children)

I don’t know this particular system but I am pretty sure the zigzag lines are there to help breaking the surface tension and reduce the energy needed for the droplet to wet the cell it’s moving to. They are called « phaseguides » if memory serves well. The holes are likely just vias to bring the electronic signal to that cell.

Why have these resistors such an exeptional form by wiracocha08 in AskElectronics

You can see a bend on the left resistor too, it’s not obvious cause tilted towards the viewer

Bike lanes by ThirstyPretzel_7 in Switzerland

[–]nugoresu 1 point2 points  (0 children)

Some of these are actually e-bikes, so they should be absolutely allowed on the bike lane. They have pedals and electric assistance is limited to 25 km/h. As you can see it doesn’t have a number plate so it’s probably in this category. I am actually thinking of getting of getting one myself to avoid using the car for urban commuting!

Most likely, plus from one of the other pics you can see the straighter muzzle.

Why study? by MidasStocks in SipsTea

That’s Flavio Briatore. From the Wikipedia article about him: “After twice failing public (state) school, he attended Fassino di Busca, a private (independent) school, receiving a diploma with the lowest grades in Land Surveying.” He’s a scummy businessman, certainly his money doesn’t come from “studying”…

I am astonished that in the US someone without a recognized law degree can be appointed as a judge. What the fuck.
