A project/circuit based on the LM3914 was featured in the November 1995
issue of Silicon Chip (an Oz electronics mag).  The PCB's for the project
(@$A5 + p&p) are still available from:

email: rcsradio at cia.com.au (with a website 'on the way)

Unfortunately they don't accept 'plastic'.

I'd be most interested in this.
