# Summary

This thing is a DIY hot air station to smd soldering.

Is composed by hot air gun, an diy electronic card, an Arduino nano, an dc dc booster, an 12V PSU an REX C100 PID controler with SSR relay.

The Arduino code and the electronic card wiring is provided in thing files.

The support is provided with a magnet, when the gun is put on the support, heating is switched off and the fan is put to 80% power to cool the gun also the led switch to red. After 30sec the fan turn to off and de led switch to blue.

I will complete the wiring explanation soon...

# How I Designed This

## Hardware

I bought the stuff on Aliexpress, but you can find these on Ebay, Bangood...

PID controller: https://www.aliexpress.com/store/product/Dual-Digital-PID-Temperature-Controller-REX-C100-Thermostat-220V-AC-with-Thermocouple-K-SSR-40A-SSR/1810061_32657394914.html

DC booster : https://www.aliexpress.com/store/product/1PC-DC-DC-booster-module-2A-linking-piece-2-24-v-input-voltage-litres-5-9/1735233_32661531870.html


## Heating gun wiring 

Yellow => ESD

Blue => 24V Fan -
Brown => 24V Fan +

White => 230V Heating element
Grey=> 230V Heating element

red => K type probe +
black => K type probe -

Red => magnetic switch
Green => magnetic switch

## Rex C100 settings

Please, see below the configuration of my Rec C100:

AL1=>1000
ArV=>0
P=>5
l=>0
d=>20
Ar=>100
r=>100
SC=>35
LCY=>0

Maybe it can be improved to have better precision...
