Attention Mr Dave Symonds

Hi Dave,

As briefly discussed previously, attached please find an Excel spreadsheet 
detailing the parts to be sourced  for a power supply project for the members 
of Adelaide Hills Amateur Radio Society. It is our hope that this project will 
be assembled using some of the facilities available at your excellent city 
location. It is also our hope that we can use this project to rope in  
youngsters into electronics (and perhaps ham radio later) via a schools 
physics program and so the whole thing has been very carefully engineered to 
go together with minimum tools and fuss, and at minimum cost.

I have no real idea of the ultimate demand for such a kit but would appreciate 
the use of your sharpest pencil on the parts list. My guess is that we will be 
initially ordering some 30 kits for AHARS members.

The kit is a true laboratory grade dual power supply with extensive 
protection,  providing 5 volts at 1 amp for logic and microprocessor 
experimentation, together with zero to 15 volts at 800mA for op. amp, timer, 
stepper motor driving, EEPROM programming etc etc. Hum and ripple are well 
under 2mV RMS on both supplies and regulation is excellent.  I believe the 
design to be very cost effective and hence highly marketable, particularly to 
secondary schools.

Best Regards
Jim Tregellas
