    Since my first class in electronics, I've taken a bit more of an interest into electronics. This is partly due to the software that I now have access to software, like crocodile technology. I've tried messing around with different circuits and it has been fun. However something I found was rather interesting and falls outside of what I know.

    There are two circuits one that looks like an oscillator that could produce a wave.

    The other would appear to be a driver circut of some kind.

    So out of curiosity how would something like this work are there diagrams of it.

    have you tried asking the person who wrote the blog?

    the board with the 4 transistors is possibly an H-bridge.

    I could find no contact information.

    If in the future when you blog about one of your completed projects, remember just how worthless it is to post photos of circuit boards but include no information about the circuit design.

    A Google Search for "DC to AC inverter circuits" would be a good starting point.

    This is not my circuit

    It works like a dc/ac inverter, just like the blog title says. Here is a concept drawing of the design:

    To learn more about inverters, follow the advice in post #4.

    Yes, it was quite obvious. But at some time in the future you will have a project that is your own. Remember then to post the full design, and not just the finished photos.

    I will certainly without question post all content involved in that situation. However I am just curious as to how you could separate the oscillator and driver circuit.

    Conceptually, the same way you would separate an engine from a gearbox.

    Good analog-y.
