We need an electrical engineer to: 1) design a blue print; and 2) build an environmental monitor built to our specifications. It will have a micro controller, a wireless emitter, an IMU, temperature/humidity sensor, a barometric sensor and a GPS. We need the environmental monitor to be put together in an attractive outer shell, so this is more than just soldering the components to a mother board. We want an elegant final product in line with some concept drawing we will provide you with.

We are working on a prop taxi meter. We'd ideally be looking for a consultant and fabricator for a LED board that could work for our 9/9-9/12 shoot. As we understand, our prop would be a x7 digit LED (7 segment) panel which can read 99,999.99. We would be responsible for the fabrication of the housing for the electronics/technology involved. In addition to reading a 7 digit number, we would also like to: 1. Turn LED digits individually on and off (have the possibility of LED digits illuminated or dark at the same time) 2. Set any LED to any digit at any time 3. increase the fare on meter incrementally higher from custom set number (just like a real taxi-is this possible?) 4. We would like to keep our LED digits around the following dimensions- 1.125" x .5" We were curious how to approach these different functions and behaviors as well as which supplies would be needed? here are some examples of what we thought might work? https://www.sparkfun.com/products/12794 https://www.sparkfun.com/products/12794 https://www.sparkfun.com/products/11405 https://www.sparkfun.com/products/8546

I want a driver to run 6 of these 24volt LED white light strips driven from a single power source. http://store.yujiintl.com/collections/high-cri-led-strips-ribbon/products/bc-series-dual-cct-ribbon-120led-2835?variant=3149575809 First see this video on driving a similar strip, https://youtu.be/jLia59KfkSw?t=1m32s Use voltage regulation NOT PWM, I need to use this light with slow motion and cannot have pulsing as happens with current lights I have. There should be 2 dials, one for brightness, one for color tone balance between the 2 color channels strips (warm and cool white) and 2 switches for turning on/off each side. 1 power cord. 2 cords to connect the lights.

You will develop the schematics (Gerber Files, BOM, and the Eagle Files) for a PCB for a component device. It is a singular function device with one chip. The main board, which it will need to fit into, and other reference component devices are all open hardware + open software. I will provide links to all of those files. You can use those existing diagrams and specifications to model this piece. The chip you are designing for has complete documentation as well, which I will provide. So, you will take existing schematics for existing PCB components as a starting guide, look at the specifications for the chip ( I will provide all the documentation), and you will design the component piece that includes that chip, and deliver the schematics files. If you have experience designing printed circuit boards (PCBs) this should not take you long.

Dear friends, Desigining and simulation (in matlab simulink) of solar power pumping system including PV panels, DC to DC converter, motor selection/ desiginig, MPTT controller etc. Our water requirement is 1740 gal/day, Pv panels should be designed for Somalia (Afgoa town: Latitude 2.0333° N and Longitude 45.3500°E). Type of motor is BLDC (Brushless DC Motor) or Induction motor 1. Complete report about the Designing and calculation of parameters of PV Panels, size of panels with calculation MPPT Controller, DC-DC Convertor, BLDC Motor. 2. Complete description about the behavior of graphs e. g. (i) At the output of PV Panels (ii) At the output of MPPT (iii) At the output of DC-DC Convertor (iv) BLDC Motor outputs like current, speed, voltage, power etc etc Best regards, Hashim Abdullahi Abdi

Project; making a device to help people sleep. Design basis; starting with tempurpedic sleep mask design, want something made from the visco/memory foam, that fits and feels like tempurpedic sleep mask - but looks like an apple product :) I will be building in electronics including an LED into each eyepiece which will need to be behind a diffuser to make sure the LED illuminates the entire diffuser if possible. I need drawings that show how this could look, and I will work out, including the diffusers in front of each eye.

Car dashcams are increasingly popular and most also come with a parking mode. However most do not come with a good parking mode or battery backup. Further they are not specifically designed for particular cars. Goal is to design a dashvue product 1. Easily installable and with working parking mode 2. Central system that can act as battery/storage/control 3. Remote access and programmable Some products to look at are Blackvue, CelllinkB.
