DIY Mobile T12 Soldering

If you're interested in DIY mobile T12 soldering, take a look at this article.

The "Bai Cai" T12 heating is fast, but the heat recovery is insufficient. T12 and the switch power supply can generate induced electricity, but many of the cheaper options don't account for this. It's said that even without a ground wire, these devices won't damage the chip, but in reality, they are still prone to burning out.

For the main control board, you can add a temperature display digital tube. Essentially, this is just a voltmeter with the decimal point pin removed and connected to a potentiometer. However, this doesn't really serve any practical purpose, because this kind of analog display combined with the T12's limitations cannot be accurate.

You'll also need to prepare some additional components, such as the handle and four tips, etc.

You can use a switch power supply and remove the casing.

For the casing, you can use a large, professionally made shell like the Makita. Then, arrange all the wiring.

Here's a potentiometer, which should be for adjusting the “temperature display.”

You can also prepare a gauge, similar to the one in the image below. You can use hot glue to attach it. The switch should be in just the right place to snap into position.

Here's the finished product as shown below.
