Doorbell Booster

My doorbell is powered by a transformer and is out in the hall
but is a bit weak...So taking a feed off of the doorbell power
when activated into a solid state relay I have rigged up some
LED Lights to a set of 26650 batteries...When the doorbell is
rung it activates the solid state relay which completes the
circuit feeding 8 volts to the LED lights and now piezo
buzzers...
This is particulary handy in my bedroom as I do sessions on the
turbo trainer...With headphones on and can't always hear the
hallway bell when the rear wheel is rotating at the time of a
session making a noise also and sometimes I get deliveries or
the postman calls.Yes it's usually sods law...when waiting round
all day they turn up at the mosy inopportune of times. [8D] [8D]
