rt_soldering_pen's Introduction

RT soldering pen

Manual

This firmware is for my project RT soldering pen

You can buy HW at Tindie

Building and flashing

Requirements

arm-gcc
cmake
make or ninja
STM flashing SW and HW (ST-Link/V2 or any ST dev-kit, like Discovery or Nucleo board)

Building is possible on Linux, Mac and also on Windows

Getting source

git clone --recursive https://github.com/pavelrevak/rt_soldering_pen.git
cd rt_soldering_pen

Building

mkdir _build
cd _build
cmake -D CMAKE_TOOLCHAIN_FILE=../cmake/arm-none-eabi.cmake -D CMAKE_BUILD_TYPE=Release ..
make

Flashing

Connect ST-Link or other SWD programmer:

HW v0.3

G : GND
C : SWCLK
D : SWDIO

HW v1.0

C : SWCLK
G : GND
D : SWDIO

If you have installed pystlink and is in search path just type:

make flash

If you have another flashing utility you can generate hex of binary file:

make srec

or building also support other targets hex and bin

Final files are saved in _build folder

rt_soldering_pen's Issues

HW and FW compatibility

Hi, there! Was not here for a long time.
I see, new HW version released with noticeable differences.
So, could I use FW 4.0 with HW 0.3.
E.g. SUPPLY_SENS now has different divide ratio.
Thanks in advance.

Hacking up a case - what screws?

Hi,

I don't have the software to open your engineering drawings, so I was wondering if you can tell me if M2 screws will definitely fit the two large pcb holes that seem to be about 2mm ø.

The component height top and bottom looks to be a bit less than 3mm so I am planning on using 3mm nylon spacers on both sides.

Thanks!

Eagle Mosfet lbr missing

You missed to add your mosfet lbr to the repo. ;)

Not issues but wishes

Nice product

Accelerometer is highly desirable like in TS100 (SCL/SDA are free)
Go to Standby Time adjustable from settings.

problem with RTM tip

i use the v.03 HW since round 3 years most time with RT8MS tip, now i got a new one, the RTM032S and they work a bit strange.
the temperature is not stable(+/- 10°) like the RT8MS (+/- 3°) and the powerregulation seems diffrent. at freeair the RT8MS power is nearly stable at round 3W, with the RTM032S the power alternates from 0W to 6W to 0W @ round 3 seconds and with this tip the pen never detect an idle and because of this never goes to idle mode.
the heat resitance shown at oled is for RTM032S 1.8Ohm and for RT8MS 2.1Ohm. i testes SW v0.4.0 and v0.3.0 without diffrents.
only part of code i changed was the heating power, i reduced it to 35W because of 2 burned tips in the last 2 years.
i dont think this is normal, is this a known issue of this tip? can i try something?

v1.0 PCB

Will v1.0 be open sourced?
Thanks!

WTF with stl???

Maybe you had to warn about?

Feature Request: Power-On-Demand Mode

POD mode.

An alternative mode where the iron is powered while pressing one of the buttons and shuts off when the button is released. The irons heat up quickly enough that this mode should be bearable for small soldering jobs. When pressed, the iron will wake and begin heating to it's set temp and then maintains that temp until the button is released, where the iron will power down.

In lieu of an audible alert when the set temp has been reached, flash "READY" in large print of the OLED.

To modify configuration while in this mode, press and hold both buttons for 3s, where the controller will wake and allow changing temperature/Mode/other parameters without heating the iron.

Can switch between Power-On-Demand/Standard modes in config.

Motivation: Increase efficiency when running iron from battery power.

I admit I have just received my first unit and haven't had much time with it, so I'm not familiar with the current features and operation. I DID want to document this thought while it was fresh in my mind.

can you publish v1.1 HW info?

Since it is almost 2 years the Tindie shop does not offer anymore your soldering pen, will you be so kind to publish the v1.1 schematics and (if possible) the gerbers of the new PCB?
