My son was invited to a Superhero/Supervillain themed birthday party. He wanted an “awesome electric gun”. So I snatched up one of his nerf guns because I’ve always wanted to do a custom build. Here’s what I ended up with.
The fuses are removable so he can pretend to be reloading. The lights are from a RC headlight kit that’s powered by a 9V that’s housed in the removable magazine.
The costume unfortunately did not survive the party as 10 year old’s in bouncy houses are quite rowdy.
