Re: Really universal soldering controller Reply #3390 – November 14, 2020, 12:38:20 am Quote from: 4nthonylin on November 13, 2020, 11:52:49 pm@sparkybg Are there any additional features that you were thinking of adding?Maybe to add option for room temperature override. The sensor for room temperature is on the front PCB, and on many calibration videos it shows 35C and more, which is not correct, and this means, for example, if room temperature is 25C, and sensor reads 35C, then a thermocouple iron without sensor in handle, will be 10C colder than reading.Maybe many users do not realize the placement of this sensor - in my enclosures it is in such position that:1. It is not warmed significantly from transformer or anything else2. It is more or less close to inlet air port on my enclosures, so there is air current close to it, bringing fresh air with room temperature inside the enclosure. This is because the rear panel has ventilation ports on upper end - the air comes from the lower part of the front, the transformer and back PCB warms it, an it exits through the upper ports on the back plate.
