/diy/ - Do It Yourself

As a /k/ommando, I sort of feel obligated to recommend you get a gun instead. Tasers, the one that launches a projectile, are a little pricey and only allow you to get one shot off before a rather timely reload. A stun gun obviously requires you to get close to the attacker(s). Pepper spray, which is definitely nice, is an extremely poor option in enclosed or tight areas. Of course, I'm assuming you live in an area that allows conceal carry or firearms. You really shouldn't put your well being or possibly your life on the line with a taser you built out of old parts. I'm willing to give you more advice if you'd like, but it may be more fitting to post on /k/ about it.
