I started this small project because I needed a way to listen to my music in the shop. Because I’m cheap I didn’t want to use anything but scraps so it’s kind of a hodgepodge of walnut, maple and oak laminate together to get pieces big enough. everything was cut by hand and I’ve already dropped it twice so there are some decent sized marks on it but it survived so I guess that’s the idea of a shop radio.

The guts are a 3w amp, a bluetooth recover, and a 1 inch speaker. Total cost is about $6. Uses a phone charger for power but any USB would work. The Bluetooth range from my phone is about 10 feet. Its about twice as loud as my phone and much better quality.

Sweet project! I have been considering this myself. Can you give some details on the electronics parts and/or sources.

Thanks!

I like the mixed woods! it gives it a good look :) plus it’s a great use of scraps. What kind of a finish did you give it?

The amps are actually stereo amps 3w per channel and can be had for about $1. Green or red doesnt matter, if you want a volume knob then they are around $2.

The speakers can be purchased as a pair or singe and they go for about 2 bucks each but if you are luck you can catch them for $1.

This is very similar to the receiver used and you can buy them for $2-$3 all day long. I pulled mine out of the plastic to get rid of some of the bulk.

It took me about 3 weeks to receive all the parts from China but I didn’t have any problems. I ordered 15 sets last week and will be selling them as a small kit to people who don’t want to wait. I wont make anything on them I just want others to have fun with it.

Have your say...
