We are a start up firm looking for an electrical engineer with experience in consumer electronics, specifically a small LED lighting product for the home. We are looking for someone who can collaborate on a design that is in prototype stage and which needs some electrical engineering advice for the LED lighting component to make sure it will work as designed, and will be manufacturable. This is a very simple light using LEDs, batteries and possibly a remote control receiver. We are working under tight deadlines and need immediate assistance.

The project is to interface a camera OV5642 with stm32L152. The stm32 should initialize i2c and configure the camera register for JPEG compression. This system will be integrated with fpga. The fpga part is ready. Once the microcontroller is on, the i2c is configured and the camera signals (pclk,href,vsync) and camera data (D0-D7) will captured by the fpga. This part is just to configure the I2C so that the camera will produce the signals and data. If this is a success, a new project will be created

I need to incorporate the technology of a non-invasive electrical tester which detects AC voltage and lights up when voltage is present with a set of pliers. Below is a link to an example of the tester. The tester can read if a wire is live just by touching the rubber.   [obscured]  /webhp?sourceid=chrome-instant&rlz=1C5CHFA_enUS503US504&ion=1&espv=2&ie=UTF-8#q=Gardner+Bender+TesterKit&tbm=shop&spd=8774199084521156521 I need help with how the circuitry would work and where the technology would be placed in the pliers. I will need drawings showing exactly how it would work. Once I decide on someone to work with, I will share more detail and the sketches I have.

We have a custom Unitronics program that was written several years ago. The original programmer cannot be located and we need to make some changes to the code. Changes include the removal of some artifact legacy code that is no longer useful. Changing some user input screens. Changing some limitations to time inputs (ncrease the maximum amount of time a user can enter), and changing some parameters for how things operate. The program deals with time, temperature controls, and relay out puts to control pneumatic actuators and vacuum pumps. We realize that it can be difficult to go behind another programmer to make changes but if you feel you are up to the challenge, we are ready to get started. We have decided that this is best tackled as a per hour project since you have no fair way of determining how much time it will take. Please provide details as to other Unitronics PLC ladder programming you have done. Program is attached if you want to take a peak before bidding

I am looking for someone to add a very simple ADC function to my current working code. here is an idea on my current code i have a circuit that has an analog op amp circuit which is responsible of applying a ratio to an input signal via dividing resistors, and i have 16 pos rotary switch controlling 16 optocoupler to control which resistor is selected so the ratio can be different, now all what i need is some one that can add a working ADC so that it can control when the optocoupler is opened and when is closed based on the input voltage. i forget to mention that code i have is been made on CoIDE i need this adc code ready in 48 hours maximum. please Bid with a reasonable amount thanks

I designed a simple chargeable lamp with MCU in Altium. The schematic as well as all components and footprints are already in Altium. I am looking for somebody who can do the routing for an initial proto PCB. - One side components - Double layer routing - 50mm x 50mm PCB - See the BOM file exported from Altium attached. The Altium files which already contain all dimensions and locations of the main components will be shared after a project has been granted.

I need a custom board designed for the Atmel SAMA5D4 that should be relatively straight forward. I would like for the design to be done in Eagle, but that isn't a firm requirement. The board will have these types of components: 1) LCD connector for a 720p display 2) 256 or 512 MB of DDR memory 3) NAND flash (for the boot loader, firmware, etc.) 4) SD Card for the OS, etc. 5) Various regulators and filters 6) A few I2C/SPI/UART sensors 7) One or two debug connectors I have a good idea of what I need and this project needs to be done fairly quickly.

Looking for a 12V DC motor control for a small 100W motor. Need a CPLD with LCD or LED Display The Display can indicate 2 Digit Count that shows time that allows motor to run for a specified time. Say Display =01 implies 15 seconds Display = 02 implies 30 seconds etc., Need a up count button and down count button to chose the correct value. Components needed : 1. Small 2 digit LED/LCD Display, 2. 100W DC motor, 3.110V to 12V Power Adapter, 4. Up button (can be simple push button) 5. Down button 6. CPLD You can breadboard it and I will get a PCB designed once the system is working. Get back to me for more specific details

We have a signal light tower, model ME-A, that needs to be connected to an integrated circuit wafer processing machine. There are three lights: red, amber, and green. See the first attached image. The second attached image has details on the required electrical connections. We need to turn the lights on and off from a computer. The computer interface is an Adlink 7442 PCI card with isolated digital outputs. See the attached data sheet. We should be able to attach three signal lines and a ground line from the 7442 to one side of the Light Control Circuit board, and the red, orange, green, and yellow wires from the light tower to the other side of the Circuit board. There should also be provision for 24V power. Given the schematic and part numbers, we can probably build it ourselves, but preference will be given to proposals that include fabrication and delivery of three circuit boards. I use the phrase "circuit board" loosely. It doesn't have to be a printed circuit...
