content: Hey Guys ,My Chinese 858D died due to heater failure so i bought two wand . with one i repaired my 858D and i had one spare so due to boredom i started working on this project. It is working alright but it has few issues. I need your help on solving these issues.1. TRIAC is buzzing (i added snubber according to MOC3021 datasheet but it didn't solve it)2. Thermocouple temperature has noise when blower fan is running.3.(Help me to connect my Hantek 6022BL to 230v AC)i will be adding few improvements later1. Capability for running Preset BGA reflow profiles.2. wand reed sensor for turning off heating element .3. Replacing Transformer with SMPSthe code can be found herehttps://github.com/Cyrilanthony777/Arduino-Hot-Air-StationThanks.

content: +1 for perfboard.Is that all solder or is there a wires under it?Also:#include<PID_v1.h>Missing file.

content: High current AC has wire under it other than that all solderPID library is herehttp://playground.arduino.cc/Code/PIDLibraryi will add it to git readme

content: Has anyone tried PT1000 sensors (PRTs) instead of thermocouples? I did a reflow oven years ago and decided to try using PT1000 sensors for the temperature and found it a little too easy compared to dealing with a thermocouple + amp + reference. The cost of the PRTs are fairly high in unit levels ($9~$15 for bare sensor) but the simplicity of use won me over.( something like this, just under $10 actually -http://au.element14.com/labfacility/dm-310/sensor-pt1000-2x10mm-600-deg/dp/859855001)KcaAk3B8P8HAQ&CAWELAID=120185580000358753 )

content: Pure beginner's curiosity: Why have the line cycle sensing pulled off the AC line voltage (via R10/R11)? Wouldn't it work, and be safer, to just have B2 coming right off the transformer secondary as well?Also, is VCC really 12V? Or is it actually 5V?

content: Yes it would work but we have to add a diode in 24v Line since the capacitor will be filtering out the signal .VCC is +5v my eagle libraries are messed up i couldn't find 7805 in TO-220 package at that time.
