Here's a video! It's absolutely incredible!!!\n\nhttps://youtu.be/vUQuWEgAX-o\n\nI repurposed leftover ABS and PETG plastic to craft my handle, and I highly recommend using PETG - it's incredibly durable. I installed one momentary switch and one on-off toggle switch. Two 18650 batteries in series power the device, which are housed in these fantastic battery cases that fit snugly into the PVC tube:\n\nhttp://www.thingiverse.com/thing:456900\n\nThe switches are wired to connect the negative wires. The toggle switch acts as a "Safety Switch," connected to the negative wire of the batteries and one terminal on the Push Button Momentary switch. When engaged, the push button switch connects the negative wire of the battery to the negative wire of the "spark" unit, triggering an explosion. The positive wires of the battery to the "spark" unit are permanently connected.\n\nI assembled the handle using hot glue and used beads of glue to secure it into the PVC tube. The batteries have a long lifespan and won't wear out even when not in use. When they eventually require charging, simply recharge them - I haven't reached that point yet.\n\nThis design provides excellent protection against stray dogs on trails, and it's incredibly cost-effective and easy to make.
