Has anyone used a Leister hot air blower to roast coffee and if so, which model did you use? What was your experience like?

Description:
A PDF file describes how Excel was used to
generate Rao-type roast profiles and then
execute them by means of an Arduino Mega 2560
which transmits thermocouple temperature and
then receives Excel generated adjustments to
a stepper motor connected to the pulse width
modulator which sends power to the heating
coils of a modified Presto PopLite popcorn
popper. Excel workbooks and Arduino sketches
for °C and °F are included.
