cheap way to ad Chromecast to your 40's and 50's Televisions

I don't know if this belongs in this thread or not but here it is.
I cobbled this little contraption together for under $75.00. I was looking for a way to broadcast old TV shows from YouTube to my vintage TV's. I have used Chromecast in my house to stream to my TV and love the way it works, so I started looking for ways to adapt it to my old sets. I came across the HDMI2AV on Ebay for about $25.00 shipping included. It decodes the HD signal from the Chromecast (That cost me $29.00 shipping included) and converts it to composit video and L R audio. From there th signal goes to the CH3/4 RF modulator (Also on ebay with free shipping) and is converted to a NTSC CH3 signal for the TV's. And WAMO you have all the old TV shows you could ever want on your vintage set. All controlled from either your smart phone or tablet.
The pictures tell the story. Please feel free to expand on this one.
