Interactive Motorola MT500 Ghostbusters radio (and antenna)

I recently came into possesion of a vintage Motorola MT500 walkie-talkie. It's not the exact model which was used in the Ghostbusters (1984) movie but it was close enough for me to work from. When I got it the device was non-functional and had an inacurate antenna.

In these two videos I take the original radio apart, gut the innards and replace with a audio FX circuit board from Adafruit. My second (much shorter) video shows me making a replica "stubby" antenna in real-time to show how quick and easy it is. I thought some people here might like to see the videos. Remember to watch 'til the end of the first one... you wont be disappointed!*



Items used:

• Adafruit Audio FX Sound Board + 2x2W Amp - WAV/OGG Trigger -16MB -
• Adafruit LiIon/LiPoly Backpack Add-On for Pro Trinket/ItsyBitsy
• M8 (8mmØ) Stainless Steel Socket Head Allen Bolt
• 8mm I.D. Clear Plastic Hose PVC Tube
• M12 Vinyl rubber bolt end cap
• 14mm shiny shrink wrap tubing

*you may be disappointed haha

Afterthoughts:

The speaker that came with the radio demands a little too much power than can be driven by the board and it's a little quiet. It sounds ok when in a room and on camera but at a noisy con its quite hard to hear. I'm going to replace it with a couple of smaller 2watt speakers which should be a lot louder.

I'm still not happy with the volume output. It's not too bad at home in a quiet room but its barely audable at a con. Does anyone have any suggestions on small but loud 2 watt speakers?

You can also make the volume of your mp3 or wav file alot louder. There are mp3 volume converters online everywhere.
