You will be required to design a 'Night Timer' system .The timer should have four 7-segment LEDs i.e. should count up to 59 minutes 59 seconds in increment of 1 second.there should be a pause and reset button. 1. Four 7-segment RED LEDs. 2. One PAUSE button and one RESET button to pause and reset the timer as needed. 3. You need to use and configure a Light Dependent Resistor for that purpose. (Note: Multisim does not make provision for LDRs so to simulate your design you have to use an Opto-coupler and potentiometer combination to represent the LDR). 4. You need to use a step-down transformer as the system will have a 230V AC supply and the timer should operate on 9V DC. 5. You MUST ONLY use the following components in your design: Power Source, Transformer, Optocoupler, Potentiometer, switches, LED Display, Resistors, Capacitors, Transistors, Diodes, Basic logic gates ICs, Decoders, Timers, Counters and Flip-Flops. 6. You CANNOT use Programmable ICs, Micro-controllers or M...

Good morning! I made a VIDEO about what I want and have attached it below. Please only reply if you can lay out the board with Ultiboard 2011 with the MultiSim 2011 schematic file I give as well as the DXF for the board outline and location of components. There is an example board that is larger than the board I need. There is an example of the smaller board PARTIALLY laid out. I can give the DXP files for the cutout and all elements. I will give my libraries as well. I use National Instruments Multisim and Ultiboard 2011 and want to stick with it even though there may be better methods available but know that Ultiboard works just fine for folks skilled in using it. I will want an example of a few board layouts. When you complete the layout and it passes the design rule and connectivity AND has sufficient line widths to support the current going through the LED's I will release the payment. Happy to make further videos and the files.

Dr. Sean Young, a medical school professor and psychologist (seanyoungphd.com), needs to develop a small quantity of head-worn wearable devices (like glasses) that are Bluetooth enabled, feature very powerful microphones for detecting words spoken in the end user's environment and by the end user himself, and feature cameras to record that person's point of view. This project requires PCBA design, layout and production of 100 pieces, as well as basic firmware design for communication via Bluetooth to a smartphone app. A very basic Android app showing connectivity and ability to upload stored video and audio files is required. It also requires delivering all schematics and firmware files. For more information, please visit   [obscured]  )seanyoungphd(dot)com, review Dr. Young's research interests and submit your proposals here in Elance only.

We have developed a board based on Arduino NANO, adding an IR receiver on pin 9, and a digital out at pin 6 for the control of the led strip. We have 14 led in 20cm. We have already created some cool light effect using adafruit library. We'd like to add in fast way some nice effect. I'll try to give you a description: - fire effect (simulation of fire) - acqua effect (slow changing of color from blu to azure) - tropical (changing color from acqua-green-azure) - ice (white and low blue) - rainbow (similar to adafruit) - one cool effect The code need to be well commented. So basically we need: - control of digital led strip - control of the remote IR controller - wake up and sleep function (low power mode for IR On-OFF)

I have 2 circuits design to be combined into 1 circuit via a switch. For your reference, both circuits are herein enclosed (both circuits are the same with the exception of R2 and this is where the switch will come into play to change circuit from one to another. I'm looking for someone to create a PCB layout which can be used to create a printed circuit board.

Ultra simple prototype running 3 servos using Arduino UNO. Mainly need to consult with someone on the best options for switches etc to run each servo independently and all at the same time etc. If you know circuit boards / Arduino you will find this fairly simple to start but could turn into a larger project later.

Looking for someone to deliver a simple electronic device that shows how long ago something was tilted. The device should go in a small plastic case, holding 1 or 2 AAA batteries. Normally the device will be in one orientation. When the device is tilted more than about 45 degrees it would reset a counter-timer. Upon pressing a button the device will blink a single LED once for each unit of 8 hours since the last tilt. For example if it was tilted 16 hours ago the LED would blink twice. Blink at 0.5 hz. The battery should last 1 year (the button will be pressed only about 100 times in a year) - this is easy to achieve with a low power MPU. The deliverable is the working device and source code. This is NOT for an ongoing product so we don't need a professional PCB etc. We do need a battery holder. The tilt sensor can be as simple as a spring wire and weight or a low cost rolling-ball sensor.

I have a small medical device that I want to have designed and laid out on PCB with the electronic components. I have the feature specifications (what it should do and what it should measure), and some of the product specifications. It will be a small device that will have wireless capabilities. I just need to have a basic design at this stage with the components identified to carry out the functions that I need for this device.
