As the Pulse Tab Welder will have an OLED display, I thought it was a good idea to add a splash screen during boot up. Here's the one I'll be using (drawn pixel by pixel in Adobe Photoshop :p ) :

Okay, It looks a bit pixelated, but that's because the original image size is only 96 by 64, in order to integrate it directly on the OLED display.

I'll probably draw other images and logos to "simplify" the use of the device (like icons and pulse waveforms for some menus, but I have to be careful not to use too much program space).
