We are looking for an ace Hardware Engineer/ Team capable of overseeing development of a (very) small ARM or MIPS (Android) wearable device. You will be informing Hardware decisions ranging from platform to peripherals and as you'll be customizing a Wearable Platform, PCB experience is a must have. An understanding of Newton2 or WaRP + a desire to be part of a team that wants to create the next great Mobile product is a huge bonus! You will ideally be located in the US, UK, Ireland, or Shenzhen and will work alongside Industrial Designers and Software Devs. Remuneration is negotiable on Experience, and can include Equity.

We have a sensor from http://www.actionxl.com/products.html along with some information about the device http://www.actionxl.com/developers.html It is basically a small accelerometer controller that uses a simple accelerometer chip to sense the x and y axis plus acceleration. We do not need all those functions except for sensing the x and y values only to TRIGGER the arrow keys. We simply need a person to help us develop a simple USB SENSOR that when tilted left or right, up or down, it will then trigger the arrow keys correspondingly. No calibration. Just be able to trigger the arrow keys as it it was a tilt switch. So as soon as an x angle (less than .5 degrees is sensed in any direction, it will trigger the arrow keys on a computer. We have an actual circuit board of our exsiting item if you need to see it. It is the size of 2 postage stamps wide.

I am in need of a custom PCB for a wireless speaker. There will be 4 speakers and it must have Bluetooth as well as auxiliary capability. I would like for you to create a schematic so that I can have a few boards manufactured. If you can create a prototype and a schematic, I would be willing to pay extra. I ask that you have experience in creating PCB's and have custom boards before. I would like a good quality board, so I am willing to pay for quality. Please provide details of past experience in creating PCB's.

We have designed and fabricated the IDU with the intent of generating a TTL (Square wave) compatible clock signal with 3-ns of rise time, and 10- 40 MHz of pulse repetition frequency (PRF) and 20Vp-p output voltage. Unfortunately due to some unidentified flaws schematic we are unable to generate the required output. We are looking for someone to help us with the debugging and building of Impulse Drive Unit (IDU). Given below are the complete details of the project, should you this interest you. • Figure out the design error in the current schematic and fix the problem. • Schematic capture, Simulation and PCB layout should be performed in Altium • Board should be fabricated and the results should be verified. • Written report with design explanation, simulation and experimental results. • Signing the NDA ( Non-Disclosure Agreement) The copy of the schematic & BOM will be made available upon request. We request you to reply back if you are really interested in this project. Thanks.

To Design and Produce a prototype as per my specifications : Combined Battery Pack (50,000 MAH) that can charge a laptop - & Hard Drive 256 gb SSD & and another option with 3 TB Harddrive Also a basic SD & Sim Card Reader should be built in to the device Should be able to charge common, Samsung, Lenovo, Microsoft & apple laptop with USB 3.0 Output also should fast charge mobile phones with other USB output Also the piece should have a meter showing exact percentage of battery left & also how much of the hard drive is used. Essentially its a repackaging and design of products that exist already. i will provide the harddrive & battery sizes & other design elements needed to design and test the product to build a sleek working prototype. Product prototype must be ready by 12 April 2016

I just wanted to clarify that the output needed to be sinusoidal. Please let me know what all would be provided with the solution. Please, find the attached file with the design requirements. Please, let me know if you need clarification on anything. If you would like to quote it in stages that would be fine. I would like it in 20 days or less, I would like you to supplying the complete tested working control and buy components, because I don’t have hardware. This project will be difficult for you if you have not developed a frequency drive before. Do you have an idea of what you would need? Have you developed a Frequency Drive or something similar before? I would like it in 20 days or sooner. I want you to supply all the material it will be great. I will send the fund into milestones based on progress. You will have to design and hardware for the VFD controlled by raspberry pi and Touch screen. The main part of the design is VFD design ok. I do not have the hardware. I am an Electrical Engineer and able to program in C/C++. I do not have the resources to develop this product so; I will need the complete solution. The main part is the VFD design and interface to a raspberry pi that will utilize a touch screen to make the output adjustments. I mentioned all the details over here for more info please, find the attached pdf file thanks.

We designed a simple electronic circuit that contains a: relay (5V 2A Finder 30.22.9.005.0010), diode (IN5817), a resistor of 6.3K and a transistor (547BC). We attach the schematic below. The PCB has to be about 40x50 mm. The aim of this circuit is to cut off the alimentation of a 12V line depending on a 3.3 line, with a delay of 60s controlled by an arduino. We need the following files: ·Gerberx2 files for the copper layers, soldermask and legend layers, mechanical layer and SMD paste layers. Plus carbon, peel-off and via-fill layers as needed. ·Excellon drill file(s) for drilling. Thank you in advance
