Enhanced fork of the weller tip based solderstation from DebuggingLab based on work from Matthias Wagner https://debugginglab.wordpress.com/2014/10/30/soldering-station/
Modified by jleg99@gmail.com, including some experimenting with highres fonts and click/rotary encoder (replacing the pot):
- code cleanup
- new shutdown mode (default: 5 minutes)
- fixed optional RGB LED and fume fan support
- measure and show Vcc and Vin (simple voltage divider for Vin needed)
- icons to show standby and shutdown modes
- PWM is visualized using a bar graph
- other splash screen :)
- version 2: support for rotary encoder and temperature presets
- i used "MK-MK146" from reichelt.de as ready-made tip connection; it has a nice flexible wire
- the Weller RT tips are rated for 12V 40W, so a power supply of about 4A is needed
- with the RT1 it takes less than 5 seconds from ambient to 280° - nice! :-)
- i used an encoder module which can easily be found on ebay, search for "rotary encoder module"
- since i wanted to use this station mainly for SMD stuff, i chose the "WELLER RT 1", also from reichelt.de
- the PCB is available here: http://dirtypcbs.com/store/designer/details/5145/124/soldering-station
- the original BOM is linked from the original site (s.a.), direct link: https://github.com/ConnyCola/SolderingStation/blob/master/eagle/BOM_PartsList.txt
- this is more or less the original version with the enhancements/extensions mentioned above
- same as above, but using highres fonts from Adafruit TFT lib
- i regard this as an "experiment" :)
- fonts fill up available flash quite heavily
- i wasn't able to eliminate flicker completely
- based on version with regular fonts, i replaced the pot with a standard cheapo click encoder
- a click switches to the next temperature preset
- a long click (hold) stores the current set value to the current preset
I used the original PCB, available from the link above. For the extensions, i soldered some wires to the pro mini socket directly:
- A0 - i used a cheap MOSFET module for Arduino, using a IRF520
- Vcc is measured using the internal reference
- to optionally also measure Vin, i soldered 2 resistors to A6: Vin o---[22k]---oA6o---[5.6k]---o GND
- this should be good for up to 24V Vin
- i used D15, D16 for pahes A/B (or Data/Clock), and D17 for the button
- for some unknown reason, the original PCB which i used had D16 connected to Vcc, so i scratched a PCB trace
- as an alternative, the now unused Pot pin A5 could also be used to avoid the problem with the trace
Standard fonts
Highres fonts
Station is in standby mode - temp goes down to 150° (after another 5 minutes, temp will go down to 0°)
Using cheap click encoder module, running "preset 1"
