Looking for an experienced PCB layout designer to design a Raspberry Pi hat, we already have a list of off the shelf components that will be doing on the PCB and the specific pins on the Raspberry Pi it connects to, just need someone to take it from here and get us a polished PCB for our application. There will be a little bit of design required to make transistor driven circuit for relays we plan to have along with a power supply circuit for certain sensors to avoid too much current draw from the raspberry pi.

I need two PCB designs for two separate Computer front panel IO's. Cosmos S: Outside http://media.bestofmicro.com/pc-case-roundup,2-E-110246-13.jpg Inside Back http://i.imgur.com/mMsodfW.jpg PCB1 This is connects to the IO and feeds power to the JP1=> JP6 the leds in the otside pic.(Yellow/Black/Greem) Connector http://i.imgur.com/OX4rJYal.jpg I only need the IO designed. and both USB upgraded to 3.0 with a Mother Board Header. Kind of like this but mounted vertical. https://gzhls.at/p/788611.jpg Second Pannel IO is for a Cosmos RC 1000 : http://archive.benchmarkreviews.com/images/reviews/cases/Cooler_Master_Cosmos/rc-1000_036.jpg http://cdn.overclock.net/7/76/500x1000px-LL-76992137_2013-07-1115.52.27.jpeg Same USB3 upgrade. Thank you Bogdan

Background - A working tethered power system for multi-rotor drones has been implemented which permits indefinite hover for surveillance applications. The challenge is that these ground power systems can only supply enough power to support hover (~1.5kw). The tether runs 400vdc and a module onboard the multi-rotor takes this voltage down to 24vdc which runs the motors. The problem is that instantaneous power demands for Take-off and maneuvering can exceed 2.5x the available current. Increasing the available current from the power supply is not an option. This requires an on-board, battery based system that can absorb the peak current requirements while keeping the primary tether under 1.5kw. Scope of Work - Design and develop hardware for the following power management system. Use a Lithium Polymer battery to absorb the momentary peak loads that exceed 1.5kw. The battery must be charged from the tether power during flight in order to maintain its indefinite flight envelope. The charge circuit along with the battery cell balancing needs to be developed and integrated with the power solution. The flight system must also be capable of recognizing if the tether ever loses power and initiate a complete switch over to battery only power. The required solution will attach to the Battery bus, and the ground power bus both typically 24vdc. When instantaneous current demands from the motors exceed capabilities of ground power, the power manager will electrically switch the motors from ground bus to battery bus. When current demands have lowered, they are switched back again. When the batteries are disconnected from the motors, a LiPo charger is also enabled.

I am developing a safety project and I need a bracelet dummie that has geolocation, bluetooth, battery included, the size of not greater than any sports bracelet, including a button on and off GPS, a button to provide information and connect to an app and send data to an application. The cost should include the manufacture of the dummie bracelet, sending it to Mexico. Please include a proposal of manufacturing cost per unit in a volume of 500 pieces a near price. You need to have knowledge of electrical engineering and manufacturing, it is not conceptual. Excuse me if my english is not so goob but i can try to solve the doubts. I dont know the rigth price so i need you to make a real proposal.

I am looking for an electrical engineer to design a PCBA that will be used to power up to 10 LED drivers. The required specifications are shown in the attached picture. The functions are similar to a brushed motor ESC for an R/C vehicle. The only main difference is that an ESC uses a PWM signal to adjust voltage output. This PCBA will use a potentiometer. Heres an example of a brushed ESC: http://www.dynamiterc.com/Products/Default.aspx?ProdID=DYNS2210 I need Gerber files, design files and BOM.
