This is a project for a do it yourself analog soldering station. The design is a variation on some low-end commercial units that don’t have a built-in temperature sensor in the soldering iron.

It’s made with a dimmer switch and a few other hardware store items. It is fairly inexpensive to make and the project can easily be completed in an evening. I needed a unit like this for some experiments I was doing with soldering irons. (more…)

This is a follow up post to the previous post on how to modify a regular plugin soldering iron to work with a digital temperature controller.

The tricky part is finding the right location for the thermocouple inside the soldering iron. The thermocouple is very sensitive and temperature readings can be affected by the slightest change in position. (more…)

Soldering irons that plug in to an AC outlet are inexpensive and convenient, but one drawback to them is that they don’t have very good temperature control. They often are either too hot or not hot enough.

Some plug-in soldering irons are adjustable. Some models have a temperature adjustment built into them and function like a light dimmer. Although better than units without any kind of temperature control, they are somewhat limited. (more…)
