Waveform Magazine Mewsic Box (Project 6) - DIY Build

Sound of Mewsic - Kit

Have you ever found yourself wanting to hear a quick sample of a new module or have your speaker for your “on-the-go” case? Well, the Sound of Mewsic module from Waveform Magazine is exactly what you need. 

(You are probably asking yourself … What is it?) 

It is a small and versatile 10hp speaker module that is a quick and easy build even for the novice builders. For our latest build, we take on Waveform Magazines DIY Project 7… the Sound of Mewsic!

Consisting of a panel, speaker, a pot, a single jack, a tiny PCB and a few other components, the Sound of Mewsic took about 20-30min to complete. 

Let's get on with the build already.... the PCB

Start by placing the power header on the backside of the PCB and tacking it down, making sure you line the notch up with the silkscreen.  Next, place the potentiometer and the audio jack on the topside of the PCB and carefully flip the board over to solder everything into place. Attach the completed PCB to the panel by the jack nut.

Evaton Technologies AModulator - DIY Build

The Evaton Technologies AModulator SDIY kit is a companion module to the RF Nomad voltage-controlled shortwave receiver. What does that mean though?

In crude form the AModulator is a RF amplitude modulator that produces a micro-power radio-frequency signal which the RF Nomad can decode. 

Still not making sense? It’s ok, it didn’t make sense to us until we dove a little more into this sidecar module. 

Simply put, the AModulator allows you to encode any audio signal into an amplitude modulated RF signal, which the RF Nomad can then decode back to audio, with all the artifacts of vintage shortwave sound.

The AModulator SDIY kit consists of two printed circuit boards and thru hole components required to complete the kit. One circuit board contains the actual electronics of the module, and the other circuit board serves as both the faceplate of the module, as well as a touch-plate antenna.
