I require the electronic circuit schematic for an electronic device, a paper scanning machine. The device is to scan single sided, black and white paper by whatever means a conventional scanner uses today. It must have an automatic document feed motor. The schematic is to be completed with altium software or similar. The output of the device should be to a mac computer via a USB port. If you can produce software for the device please mention that in your bid (but you are not required to have the skills to produce the software in order to make a bid). Also please contact me if you require more details and/or clarification. I will consider bids in all price ranges. Please send examples of your work. Thank you.
