#[constraints]
#No specific constraints must be fulfilled in order to run the process.

[tools]
# The required tools:
# Soldering iron. One with temperature control and a stand is best. A
# conical or small 'screwdriver' tip is good, almost all irons come with
# one of these. Do not use a "ColdHeat" soldering iron, they are not
# suitable for delicate electronics work and can damage the kit.
- object ? (category ~ "SolderingIron" & temperatureControl = true
  & stand = true  & tip="conical" & producer != "ColdHeat")
# Multimeter/Oscilloscope: A meter is helpful to check voltages and
# continuity.
- object ? category ~ "Multimeter" | object ? category ~ "Oscilloscope"
# Flush/diagonal cutters. Essential for cutting leads close to the PCB.
- object ? category ~ "ShearCutters"
# "Handy Hands" with Magnifying Glass. Not absolutely necessary but will
# make things go much much faster. You can either get the proposed
# combination or any generic "third hand tool".

[input]
# The required input:
# Solder. Rosin core, 60/40. Don't buy a tiny amount, you'll run out when
# you least expect it. A half pound [0.23 kg] spool is a minimum.
