“This is a lovely little kit, really easy to get things connected and up-and-running. The tutorial is nice and clear the code provided practically invites you to try some different things! I ended up using an alternative glass flask with mine (a Stormtrooper helmet) and there are all kinds of possibilities.”
“Review updated See note further down re LED format
Arrived today. Simple to assemble and get up and running. Connecting the LED cable to the board terminals can be a bit fiddly as the stripped wire is very short, an extra 0.5 - 1mm would have made it easier. Looks nice when up and running.
Have been playing around with it using the example, and it looks very effective. The weather and Moon examples are something different. Other plasma examples, such as Random blinkies can also be run (you may need to change the LED number to 50 for best results).
Skully LED colours
The main control is the Plasma Stick 2040 W
The supplied LED strip is not the standard RGB format that programmable LED strips (like the neon strip etc.) are. The supplied strip is GRB format, which means that the green and red are the wrong way round.
Programming Red using RGB is (255, 0, 0). For Red using GRB, it is (0, 255, 0)
If using the colour wheel, RGB format 0 = Red and 120 = Green. In GRB format, then 0 = Green and 120 = Red.
If using examples based on the standard RGB (such as Plasma 2040), with the supplied LEDs, then you will need to amend the colour values to get the same colour when using the same example on the Skully GRB LEDs.
Plasma Stick 2040 W
The examples included on the Plasma Stick W are based on the GRB LED format for the supplied LEDs. Using standard RGB format LEDs with the Stick's examples will mean that the expected colours are different - Red will show as green and Green will show as red. E.g, the fire example on RGB LEDs will show green yellow instead of red / yellow.
Standard RGB examples will show the correct colours.”
Ahoy! Thanks for the review! :)
If you use the Plasma Stick examples they should default to the correct colour order for the LEDs in this kit: https://github.com/pimoroni/pimoroni-pico/tree/main/micropython/examples/plasma_stick
