I’ve been talking with a friend in the home automation business and he reckons there’d be a small market for an RS232 controllable volume control. This device would allow a home automation processor to control the volume on an amplifier which does not have any other means of remote control.
Now I thought that would be a pretty simple thing for me to make so I built a prototype. It only took me three evenings to cobble together something that works, thanks mainly to RS Components‘ free next-day shipping for electronic parts. I think this will be my next product.
Of course I can’t sell it in this state, it’s funny but taking a product from prototype to production is usually more work than making the prototype in the first place.
