In this video I show you step by step how to build a handheld portable train air horn!
It's super easy and fun build, simply uses a drill for power and housing, budget friendly with the horn kit only $30'ish on Amazon. This horn blasts SUPER loud, with an "unlimited tank" with rechargeable 18V batteries.
