Should you be fortunate enough to still have one of your old Fisher Price cassette player — found it alongside your Pocket Rockers, slap bracelets and Benneton sweaters — you’ll no longer have to look at your beloved personal electronic “stereo” as a technological fossil. You can thank Matt Gruskin for giving the device a second look — and a second life — as a retro-styled Bluetooth speaker.
Hackaday explains Gruskin’s cleaver strategy of combining electronic and mechanical hacks with a dash of custom 3D printing:
[Matt] selected an off the shelf Bluetooth module and another ready-to-go audio amplifier board. He built a custom board to convert the stereo output to mono and hold the rotary encoder he used for the volume control. An Arduino (what else?) reads the encoder and also provides 3.3V to some of the other electronics.
The really interesting part of the hack is the mechanics. [Matt] managed to modify the existing mechanical buttons to drive the electronics using wire and hot glue. He also added a hidden power switch that doesn’t change the device’s vintage look. Speaking of mechanics, there’s also a custom 3D printed PCB holder allowing for the new board to fit in the original holder. This allows [Matt] to keep the volume control in its original location
These types of DIY projects never cease to amaze me and put a smile on my face. So, Matt Gruskin, thank you for bringing an awesome sliver of our childhoods into the modern tech era.
