Everyone need the electronic projects that correctly works.
The collection electronic circuit to show you that not enough.
Because sometimes them may not works, so you lost times and too much money.

I need to see you happy with your projects.

Therefore, I will experiment build them to assure to you that It is really works. But this working must to use long times and a lot power. Please wait me.

Because we have more than 700 electronic projects. It may cause you difficult to find them.
