I am looking for a custom pcb to be developed with will connect a Spark Core and a OLED display that uses a flex cable connector. I have experience connecting displays that have thru-hole connection points and would like to move into a much better display for my project. In order to do this, I will need a custom pcb developed. Requirements - Develop a sketch using a common CAD tool that will generate reusable project files - Deliver 3 working sample boards - Board must be tiny, smaller dimension than the display Components I will provide one of each of the following to work with if required. 1) Spark Core - [obscured] /#/hardware 2) US Micro Products 3.2" White OLED USMP-P21301 - [obscured] /displays/oled/32-white-oled-usmp-p21301 [obscured] /sites/default/files/datasheets/USMP-P21301.pdf 3) Omron XF2M-3415-1A Connector [obscured] /ProductDetail/Omron-Electronics/XF2M-3415-1A/?qs=sGAEpiMZZMs7i6cT...

I am looking for an electrical engineer to help design a high voltage DC motor controller. The rest of the circuitry (processor selection, discretes, display, user interface, software, PCB layout, etc) is already being managed by our company. We are only looking for the motor control block. Brief specifications: -- Input voltage = 500V max -- Rated motor voltage = 90VDC (must also be compatible with 180V DC motor) -- Rated motor current = 28A max (more needed for start up) -- The motor only operates in one direction. -- Only one speed is needed -- Load is pretty consistent/changes gradually -- Standard industrial temperature and humidity ranges apply -- BOM cost must be considered but not extremely limiting -- We want one circuit board to be compatible with different motor types (1HP, 2HP, 3HP and 5HP) even if it means we have to change jumpers or use different firmware, etc. Motor datasheets and more information is available once the project begins. At this point we are open ...

I want to design a single PCB which has 3 different A/V receiver's on it. 1080-1120-1160-1200-1010-1040-1240-1280MHz rx 1 2414-2432-2450--2468-2370-2390-2490-2510MHz rx 2 5705 5685 5665 5645 5885 5905 5925 5945 5733 5752 5771 5790 5809 5828 5847 5866 5740 5760 5780 5800 5820 5840 5860 5880 5865 5845 5825 5805 5785 5765 5745 5725MHZ RX3 each tx output needs L/R audio to a dedicated 2.5mm plug each video out needs 3 buffered outputs. 1 output to a single rca and 1 output to a switch for the 3 rx outputs for LCD display and the last output will be to pin headers. the switch would switch both outputs simultaneously. it should display on the video output the band and frequency being selected for 10 seconds. the frequency and video switching must not be via dipswitches. it should be via ch up or ch down. power input will be from 12.6v-10.5v At 10.5v it will sound a low voltage alarm.

Hey. We are two young guys from Denmark who would like you to do some work for us. We hope that you can complete our idea and a long future cooperation. The idea is that we will have made some kind of power bank, but this idea is a little different because we need you to make sure that you avoid all conjured. that is, it must be a one-time charge which can be sold to those who are on the go. So it should be as small as possible,and which both work for Apple and other mobile phones such as Samsung, LG, Sony & HTC etc. The four last mentioned using happily the same charger. So in short, it should only be able to work again without re-loading. The design must also be cool to look at. We hope you understand our point and you are welcome to contact us. Best Regards Mohammed & Mohammed
