I want to build a PCB with the following features: IR transmitter/receiver ZigBee transmitter/receiver ( already built in cc3200mod ) Antenna to increase RF signal strength. Extra memory to store actions. RTC Temperature indicator Motion indicator Micro USB for power USB port to use dongle if no WiFi around. Ethernet port Reset button Power button for on/off LED Light indicator for power LED Light indicator for Internet connection Screen to show time, date, and room temperature (user can use this device as a clock) This PCB with IR transmitter/receiver will act as a universal remote and as a ZigBee transmitter/receiver. Both for Home Automation. My team has finished developing the iOS and Android apps. Backend has been developed on AWS. I have ready API’s and ready structure for the communication between the device and the backend.

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.

I am searching for an electrical engineer that can take my idea and bring it to life. This project involves US standard electrical outlet knowledge, and the ability to integrate USB currents and small motors. The first step will be creating the product. You will understand the idea, and find the best way to achieve it. The second step will be creating a working prototype. You will submit a video of the product working. The last step will be designing it. This will be taking the idea and coming up with a consumer friendly design that looks good and is still functional. I will provide a description of the product and some really bad sketches to all that apply. You can look at it and send your quote to bring it to life.

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
