Quick and Dirty Reverse Sound Cassette Mod: Easy, no cost, no solder to a new $20 cassette player

A short video that takes a cheap cassette tape player that's glutting the market now that makes for an simple modification to reverse the sound while keeping normal play working too. I've done a couple of these and it takes around an hour - and that includes playing with it afterwards. I have a longer version that includes a PWM speed mod for an additional couple of dollars here:    • Quick and dirty mod to a $20 cassette...   Honestly, it took me longer to do the video than the mod! To find the cheapest version, go to Amazon and search for 'usb cassette mp3 player' then sort 'from low to high' all of the same model has the silver band around the middle - just different outside graphics. Requires only a tiny phillips screwdriver and something to cut plastic. Maybe a small file and a spudger for opening the case unless you opt for the speed mod.
