If you're interested in building your own DIY OLED T12 soldering station, this article is definitely worth checking out.
If you happen to have a 24V 3A power supply but aren't sure what to do with it, why not follow along and assemble an OLED soldering station yourself?
The materials you'll need are shown in the image below.
If the two wires in your kit are both red, make sure to mark one of them with a black marker to avoid confusion later on. The assembly itself is pretty straightforward. You'll just need to screw a few screws into the case, solder the power wires, and deal with the rear switch. The original rear switch is too big to use, so you can simply stick the octagonal socket onto the back of the power supply using 3M double-sided tape, aligning it roughly with the original input hole.
Once the casing is fully assembled, it should look like the image below.
You can even stack this setup together with the soldering iron holder for a compact, all-in-one design, as shown below.
And that's it—your DIY OLED T12 soldering station is ready to go!
