4-5 week design cycle. Extremely reliable. Fail safe. Size, weight, power should be minimized. Vibration resilient. EMI resilient MIL-STD-464. Design PCB and required firmware/software to convert about 12 0-5 volt analog inputs and about 12 thermister inputs to a canbus or rs-232/ttl level output. Canbus preferred. 10 bit or greater, data rate should be 1hz or greater. The number of inputs can be negotiable (for example if your microcontroller can only do 16 I/O). A second section of the board(s) should interface with two Novatel OEM615 GPS boards to provide conditioned power (I believe 12VDC and 3.3VDC), 232/LVL conversion, and mechanical attachment of GPS boards. OEM615 boards require the two voltages, two traces between the two for comms, and a level converter for one of the boards (they communicate on TTL and we need 232). This new PCB will essentially be a motherboard. +12 volt DC input (PCB must condition as required) Temp rating: -26F to 160F operational, -50F to 160F storage...

UPDATE: April 11, 2014 We are going to postpone this project as it currently is (addition of a separate sensor PCB) as we test using a off the shelf sensor board. If this method works, then we will be going straight into the development of a redesign of both the module and additional sensor boards. This posting will stay open until it automatically closes. We won't be selecting a freelancer until after our testing. Thank you We have an RF transceiver Module used in a mesh network that does not require any external components to operate but we would like to add additional sensors to it. You can view the module here   [obscured]  /weben/index.php?sekce=products&id=tr-52d&ot=transceivers&ot2=tr-52d Any questions, just message me. Thanks Neil

Hi there, we are new start-up company looking for a contractor to help us take care of several of the technical aspects of our first product. Our product will be an anti-theft, loss prevention and statistics tracking device for skiers and snowboarders. We require a contractor to oversee two aspects of the product and consult with us: 1. To design, produce and test the PCB for the device. 2. To oversee embedded programming that ensures a reliable connection to iPhone and Android smartphones via the new Bluetooth Low energy standard. The product description and the technical specifications have been attached. Skiing or snowboarding experience and passion on behalf of the team would be a great advantage. The project will be considered finished with a 6 functional prototypes which can connect to a smartphone app and be programmed. It will also include the hardware designs ready for mass production. Detailed lists of the tasks are given in the attachments. Please let us know if you ...

Concept: 2 flexible LED screens controlled by a small - very small - master controller. Screen will show static or dynamic patterns of symbols and or text as well as different colors. Communication via bluetooth or zigbee or any other. Charge via solar, batteries or computer. program via computer or cell phone - perhaps an app? Attached is a diagram to give a general idea. We would also need a prototype made if possible but not a must have. We want to build a long term relationship with a provider for this and future projects.

I am looking for someone to design me a PCB that integrates several off the shelf components. I have found these parts as libraries on eagle cad. The final PCB design will be delivered in eagle cad (or similar) and also gerber files. It needs to incorporate a power input, voltage regulator, atmega (arduino) microcontroller, radio receiver, audio amplifier. I can provide schematics I have found for most of the components in break-out board design. I have attached a diagram showing the current circuit in breadboard. This currently works, although I am happy for you to propose any improvements. The PCB MUST not contain the breakout boards I have shown - ie instead of the Arduino Pro Mini 3.3v, you use its components such as the ATmega168 controller, crystal, pull up resistors, etc. Please note, the speaker, the LED ring and the antenna will be off the board. We simply need connectors for these. Also, we do not need to change the volume on the amp so you can omit the variable resist...

We look for design dimension and simulation of 3D Antenna integrate in can case. The Antenna design has to be 50 ohm with small-sized and high-gained, see photo. The design has to maximizing the antenna power radiation for 2.4 Ghz to 2.5 Ghz range. The PCB is FR4 is: 1mm, dialectic is 4.4 and has GND layer. Since we design many sizes RF PCB for Bluetooth Low energy, will be following works base on this design, when the changing factor will be the PCB size. The height and the insertion point will be the same in most cases.

I have a board that was designed in 6 layers, using a blind via and very small trace paths, and as result has increased the production cost greatly. What I need is for someone to take the current design schematic, and either separate the design into two independent boards that interface with each other and mount within the same enclosure space, or fix the board so that it is not so closely to produce, meaning increase the trace or component issues. Because of time, I am in need of this fix quickly, in a matter of days not weeks, so that the board can be produced. So if you are selected for the project please do not agree to this unless you have the skillset to complete it within the timeframe required. This is not a, from the ground up project, as the PCB has already been designed. So the project requires the following just to recap: 1. Separate the existing PCB, (BRD file will be provided after award), into two boards one with 4 layers and another with 2 for example, that result...

We need electronic circuit solution to create "Mini Ultra Sound Speaker". o Requirements - The speaker should have stereo audio input to receive signals from any audio device. - The input audio signal is standard audio signal in range 20Hz-16Khz. - All other input frequencies should be filtered out. - The electronic circuit converts input signal from input audio to frequencies above start frequency. - The start frequency should be internally adjustable form 10Khz -40Khz. - The circuit should be able to transmit higher frequencies started at start frequency without any signal distortion. - To achieve no signal cut-off at higher frequency, piezo or suitable emitting sound element "mini speaker" should be used. - There should be external switch to switch between normal frequency (no input sound conversion) or higher frequency. - The circuitry is powered via rechargeable battery. - Battery recharge is made via micro USB connector...

Our product is a portable security system that users will be able to install and use without having a technician. The user will buy the "box" and plug it in to the available power at home, after which they will fit the sensors around their house. The sensors initially will be standard magnetic open/close sensors for windows and doors and motion activated sensors. All sensors will run on digital signals. The box will receive an alarm signal from the sensors causing it to go into an alarm state using flashing LEDs and buzzer. In addition the box must be able to communicate with a smartphone using either WiFi or a GSM connection. For this project the we need: - The design must be able to fit into a cube that is 10cmx10cmx10cm - A full circuit design that is capable of taking in 8 sensors using fail-safe design methods - The circuit must also have outputs that will power the buzzer and the LEDs - The circuit must run using a microcontroller with a module to communicate via WiF...

Searching a design consultant who is able to design a compact 60...70W, PFC-equipped constant-voltage SMPS with multiple outputs for a LED lighting application. The project has a certain challenge in size, but other than that shall be a rather straightforward flyback design. The design contract encompasses circuit design, magnetic design, PCB layout and functional verification. Material sourcing and prototype built would be expedited at our side with prototypes shipped to the consultant for verification.
