Oscilloscope and Battery

I half lied in the last post. I got it to work after posting it. It was a licensing error, and I just needed to do something to the FLEXnet file in Services. Anyways, here's an oscilloscope and a battery. I know, I know, the graph would technically not really be possible from a simple 9V battery, but I tried my best in this. I know both of them aren't drawn well, but I'm no Monet or da Vinci. Either I draw neat lines that actually look something like clip art, while sacrificing details, or adding lot of detail in PhotoShop, but it doesn't look as clean cut as these. I don't know how to vector in PS, and I don't care to learn it there, as I can import vector drawings into PS from illustrator if I actually cared to make these images more detailed. Anyways, that's that, remember, click the picture for a larger image. They are all 10 by 10 inches. You may use them, but please don't blur out my mark. I don't rip the images from the internet, and the mark is tiny. If you are going to use it in a document, you can remove it from the image, but put my blog in the sources. Merci beaucoup.
