| 10:49.17 | sbaader | I created an edc file with a textblock. It seems it get mouse events (I get signals about cursor and selection changed), but no keyboard events. The text is not changed. |
| 10:49.48 | sbaader | I can set the text programmatically. (I'm using Python bindings) |

| 19:03.59 | g1powermac | solar, interesting, I found another site that utilizes the concept of that circuit design but for a slightly different application |
| 19:04.42 | g1powermac | solar, it seems that inductor used causes a resonance with the piezo driving high voltage levels to the piezo |
| 19:05.30 | g1powermac | just not sure how I can adapt that to the specific piezo I'm using |
