I have built a prototype using GHI electronics' .NET Gadgeteer mainboards and modules. Specifically, I have used the SD card, RS232, display T47 and USB DP and the FEZ hydra mainboard. I have integrated these into a single schematic (except the display) in Eagle that I would like validated professionally. Then, I need the board routed and laid out. I can provide the schematic.

The object is to build a web based application. Budget is not constraint now. Takes input in the form of a collection of one or more images The input will also include a structure/arrangement of images. Identify similar structure in a large set of PDFs containing images Display results that match the structure and individual input images The above application will be used to find the presence of small circuits within large circuits. So a user can provide images of two transistors connected in a particular way. The system will then find a similar arrangement in all the other circuit images that it has in its database. Opencv can be used for image processing. Type of application development required: New Application Integration requirements: Standalone Application Purpose or functionality of application: Take set of images as input Take structure as input. Structure defines how these images are arranged w.r.t each other Identify similar structure/arrangement in the set of availab...

I currently have a flex circuit that has 8 components on it. I would like a new pcb designed that would relocate these 8 components from the flex circuit to the pcb. Dimensions for the pcb will be provided. I do not know if all 8 components can fit within the available space; that will need to be determined. If the components can fit within the available space, deliverable will should be all schematics and files necessary to produce the pcba.

We are a start-up (  [obscured]  ) developing and manufacturing integrated micro-electronics circuits (chips) that are used by scientific community to study neurons and in particular neuronal networks and retina. For instance, a network of neurons derived from stem cells can be cultured on our chip up to form a sort of "mini-brain" and then our chip is able to sense the electrical activity of the neurons (which is the language used by neurons to communicate) in order to study neurodegenerative diseases such as Alzheimer's Disease. Our devices represent the interface between the neuro-biological world and the digital-electronic world. The novelty is that our chip integrates thousands of sensors (each sensor can interface with a neuron, hence we can read-out from thousands of them), while past devices had only ~60 sensors. We need an illustration (either 2D or 3D) to express these two main concepts: (i) neuro-chip interface and (ii) high-resolution. The illustration should sh...

I need an electrical engineer to help me design a small ultrabright LED prototype product for my clothing line. I have 3D renders completed and a basic idea of what I want in the electrical platform. Although, I do need the entire interior electrical platform built for this product. I am hoping to get the prototype built and a small product run completed at least 12 working units. This is a pretty simple design and functionality. I am also looking to have this completed in the $1000-$2000 range. I look forward to hearing back from you all.

Reverse engineer a CDI from a Honda motorcycle and add a Bluetooth Smart Module (Bluegiga BLE113-A-M256K Bluetooth Smart Module) and micro-USB port so that new firmware can be loaded. The module is used to control the spark timing curve via an iOS app that has been written for the electrical engineer. The electrical engineer will be provided with a DKBLE113 Development Kit for the BLE113 Bluetooth Smart Module, multiple Honda CDIs, as well as the iOS app that interfaces with the module. The engineer's plans will be sent to a supplier for manufacturing.
