Intro: Ray Gun Volume Control
My son has a ray gun.
It is very loud & annoying!
My wife said "take that thing to TechShop & don't bring it back until its silent!"
Step 1: Crack It Open
I took it to the electronics lab at TechShop & opened it up to see what I was working with.
Step 2: Prep the Speaker Wire
I decided rather than making it completely silent, I'd install a volume control.
I cut one of the speaker wires & stripped the ends.
Step 3: Install Trim Pot
I spliced in a 1kΩ trim pot.
Be sure to use heat shrink or something similar so the leads don't short.
Then glue in place with some hot glue.
Step 4: Drill Access Hole
Finally, drill a hole to access the trim pot with a screw driver.
Violà, happy wife!
