Product: Ventilation fan for marine application. Speed adjustable via trimpot knob. Needed: Please design a compact circuit adequate for marine environment that will power 12v fan and can be adjusted via 10k Trimpot or similar. Details: A few fan manufactures allow adjusting fan speed via trimpot but I can't find stock. I've seen a few designs for PWM with 555 timers but circuit needs to fit inside the fan case and work with 12v. Heat dissipation should be minded as case is plastic. * Find 12VDC, 80mm x 80mm, IP68 fan. Perhaps something like: - http://www.digikey.com/product-detail/en/sunon-fans/GF80251B1-000U-SE9/259-1726-ND/5285623 * Use trimpot to adjust speed. Something like this one or in the same package: http://www.digikey.com/product-detail/en/bourns-inc/3386F-1-103LF/3386F-103LF-ND/1088491 Please supply: * Shopping list, preferable Digikey, ensure available stock. * Layman's circuit design.

Hi, We are a fashion design studio creting various projects and design for a variety of fashion brands mainly in leather goods. For a project that we are working on we need the assistance of an Electrical Engineer either experienced or willing to give it a shot to create an INBUILT portable battery pack with wireless charging possibility for handbags and other items. Initially we would like to build a simple prototype with products available in the market such as: WIRELESS BATTERY PACK USB CABLES WIRELESS CHARGING MATT (To charge the battery pack) & OTHER PARTS (As required) Some adjustments will need to be done to these readily available products to match the design constructions required to test in our bags and this is where we need your expertise. Attached is a very basic drawing of what we are trying to achieve. Ofcourse to start with we will need a simple put-together prototype to test and perfect. Hopefully this is a project you can assist us with. I look forward to receiving your notice of interest and we can discuss thereafter how to proceed. Thanks SAM

Looking for a qualified electrician/electrical engineer to provide math formulas for an online solar energy system quote estimation page. The formulas need to be understandable to a team of programmers to use for a website. Shortly said, the idea is that the user will input the electrical devices they use on a daily basis, and the output will be the following: - Estimated amount of 100w solar panels needed - Estimated amount of 12v batteries needed - Estimated amount of inverters needed - Estimated amount of solar charge controllers needed Can provide more info and details in private messages to qualified candidates.

Development of a power supply for our modular controller system. Design will conform to our design standards and package requirements. High level design specifications: Input Voltage: AC(single or three phase)/DC, Min voltage 30VDC to 480VAC(678.72VDC) Outputs: Vout 1 24v 20 Amps, <80mv Peak-Peak ripple Vout 2 12v 20 Amps, <40mv Peak-Peak ripple Vout 3 5v 20 Amps, <40mv Peak-Peak ripple Current/Voltage monitoring on Input/Output voltages and Output voltage trimming through Ethernet control interface. Xilinx Artix FPGA (we can assist in the FPGA programming if needed, we have a default FPGA Circuit already designed ) with Ethernet and JTAG interface. Designs done in Altium Designer software with our component library (we have extra seats available if you do not have access to the software, if you are unfamiliar with the software you will need to familiarize yourself outside of the scope of the project). Please respond with a general outline of your proposed power supply design (block diagram is a bonus), why you are a good fit for this project, experience level with altium designer, projected timeline with milestones and cost. The individual awarded this job will have first access to our other contracts as they become available. Thank you.
