Done, here’s all my building stage
i added a power switch with an indicator led to the circuit
all in a box with some paint and hot glue
add a power socket too
first test, all work fine
but I found that we saw the leds too much, a light that was not diffuse enough
with a second layer of plastic it was much better, so I built a mini wooden case, which I painted and fixed the tube inside
second test much better
and to finish this endless post, a short video in action triggered by the kick
