I have created two simple logos. One with a white background and other with a grid style. logos i designed are unique and powerfully convey the message of your company. i used a Zener diode symbol to convey a message to people who have knowledge of engineering field. i used green color for people who dont have any knowledge of the field and for them embedded systems are like large number of green sheets with devices on them. and red color was your choice so i used it in "simply" and i personally think it looks good and is an eye catcher. i did not add any shiny effects and tried to keep it simple and elegent.if you want i can also provide you with all black formats for black and white and .eps format so that it does not loose its quality on banners. waiting for your posotive feedback.
