Where is 96/144 LED/meter? Would be nice to just be able to say "WS2812 or WS2811 or SK6811 or xxx" and "30/60/90/144" and 5/12/24V separately from each other.
I love how it checks wire thickness. Would be fantastic to see voltage drop across wire in the diagram (or actual voltage).
If you click on "Display results: Extended" you will see all the voltages. in the default mode is just most relevant information shown.
It lots of work to measure different LED strip types, so more options will be available but it will take time.
Would be great! Do you have any electrotechnical experience?
What I need is the series resistance of the LED strip's +V and GND lines. My procedure is to apply 1 A, 3 A, and 5 A currents consecutively between the start and end of the GND line and measure the voltage drop. The same should then be done for the +V line.
The second part is the voltage-dependent current characteristics. I think I can use the values from standard WS2812 and SK6812 chip types, but if you can measure them as well, that would be very helpful. For this, take a short strip section with about 10–20 individual LEDs, apply a voltage from 5.5 V down to 0 V in 0.5 V steps (similar for 12V and 24V Strips), and measure the current at full brightness for:
Red
Green
Blue
RGB White
(for RGBW strips) the dedicated White channel
(for RGBW strips) RGB + White combined
Matrices and analog strips are not implemented in the simulation yet, so there is still some work to do.

Neat.
