Thanks for the excellent post! I bought some TCSS parts from JQ Sabers here in the UK for a very basic stunt saber. I started out with a buck puck and 2 x TrustFires then I swapped over to a resistor + a single Panasonic 18650B when that ran too hot and the batteries drained too quickly for me (1.5 hours). I'm looking for serious endurance for costume trooping whilst I spin and freestyle duel. Here's a photo. I'm not a huge fan of the colour (cyan) but this is just a test build. I'm using JST connectors on the LED module so it can be easily swapped out for other colours.

Next step is to start playing with sound, extend to a staff saber, weather, add more detail etc. Thanks again!
