DIY T12 Sleep Controller for White Light

If you’re interested in modifying a simple white light controller using the T12 easy sleep control board, you might want to check out this article.

As shown in the picture below, this is an external power simple white light controller.

This controller is pretty handy, but it doesn't have a sleep function.

The components of the T12 easy sleep control board are shown in the picture below.

This T12 sleep controller uses a microcontroller as the main control unit. A regular potentiometer sets the temperature, and a vibration switch on the handle is used to control sleep mode.

The tactile switch can be used to set the sleep time.

So you'll need to make a hole for the sleep switch.

You'll also need a handle and a 5-core wire, although in practice you can get away with using a 3-core wire.

Actually, you only need a 3-core wire. On the handle side, connect the soldering iron cores to T+ and T-, one end of the vibration switch goes to the soldering iron core's T-, and the other end connects to the handle wire.

Once it's done, it should look like the picture below.

This heats up quickly and recovers temperature fast, but while working, the heating light flashes very quickly, which might be uncomfortable to look at.

One more thing: the design is set so that heating flashes a blue light, and sleep mode lights up red. If you find that looks a bit awkward, you can make some changes later.

And that's it!
