The free axle tester is so simple that everyone can do it

The axis tester I made by myself has two layers in total, one is the PCB and the other is the positioning plate. Compared with the ordinary axis tester, it is more in line with the structural design of the keyboard itself.

The package is made of Kaihua hot-swappable, so Kaihua's hot-swappable shaft seat can be soldered to it.

For your convenience, I drew three PCB diagrams.

One is the ultimate white whoring version, with 10x10 full paintings. The two are put together, and a lot of magnetic lights and touch lights of the Duomaru model are plugged in. In the end, the board was successfully built for 0 yuan, oh yeah!

If you have this, it will be more economical, but the difficulty is that you have to cut the PCB yourself after you get it.

The other two are separate PCB boards and positioning boards. JLC's free plan is for two times a month, so if you use them both times, you can use this one, hahahaha, but the disadvantage is that it is a waste of free opportunities.

So everyone chooses according to their needs.

In terms of design, I am a fan of Unicorn Gundam, so I designed it in a unicorn style. Personally, I am quite satisfied with the final result, hahahaha.

In addition, I actually did some calculations. If you don’t want the magnetic lights and touch lights, you can completely delete them, and then make 10x10 rows and columns with 5 axes. An axis tester has 25 axes. You can also add them yourself. The circuit can simply be made into a small keyboard, but since you still have to buy components, it is not completely free.

Of course, you need to draw the drawings yourself for this part. Don’t ask me why I didn’t draw it, because I am lazy.
