How do I improve a simple home-made capacitor?
$begingroup$ If you connect the capacitor to the LED via an inductor, you will deliver a much larger fraction of the capacitor energy to the LED (so it will be brighter). Wind 1 m of wire in a small loop and use that. There is a risk this would damage the LED (as the voltage reverses) -- so connect 2 LEDs in antiparallel.
