Project logs / Re: Really universal soldering controller
Here is the last update of my sensing board.
https://www.dropbox.com/s/f8xn1gbx26oljw6/V1_3_Tested.3gp?dl=0
 New feature is added – to stop the heater with a delay, when changing plate has a contact. It will prevent switching on the heater from any event, which could happen, the time we exchange the cartridge. MCU pin On/Off is connected trough buffer and cannot direct rule the heater driver.
No need any more to connect the two plates together, they sense two different circuits and both works separately.
The sch. again is very simple, a few components were added only and the board dimensions remain the same.
I forgot to mention the connection way. It is here:

This has a direct impact on ISR timing and could lead to unpredictable behavior of the future versions, even if it happens to work in the current one, so I strongly suggest not to use this kind of hardware hack!
The update is done to protect users from burning their stations the time your fix is published. It is only for that purpose. It easy can be reverted back to the common sensing circuit, by omiting some components. The bufer doesn't have a single ns delay, when in use, but as I said my intention is to help users, not to hack your hatdware.

Thank you. Cd4001 is still not ideal after many times of optimization. Now that sparkybg has designed a new Sch, I decided to try it out. Rather than continue to optimize. As for the interference problem, the program can not feel it, but my friend modified the program and added a state. So it can be seen that the source of interference is contact with the dormant board. When the power is turned on, the interference will occur at full power, as long as it is not full power.
Please, don't compare my older versions to the latest rip off.
You can add extra filtering to 3.3V supply ( read prevuos posts ) at the board and check J2 connector. if you use aluminum holder it easy to gets oxidation.

Don't spend your time for a new sch. except you found mine it is not working, it will be the same toy, just in different color.
I am asking again Are you going to assign a new input for the "Hibernation” signal or not.
