hello Guys, i have a small electric circuit working with generator principle that needs to be improved. a PCB with coil on it passes by a magnet. the induced Voltage is then kept in Ecaps and is slowly released to drive 2 standard LEDs. please see attachment. the whole PCB is rather simple. only 9 components so far. in case there is small money needed for component etc, we will pay extra or ship from here...

I have a wireless flash trigger transmitter and a receiver. They work with a Amiccom A7105 chip. I want to develop something similar with an Atmel microcontroller and this Amiccom chip. I'm a electronic engineer and I need support for this project. I DO NOT need someone who writes all the code or design all the schematic, I NEED someone who can explain me some points : 1) I need to know how my trigger transmitter and receiver works(probably we need read the signals transmitted and received) (1-2 hours) 2) If they work with RF I need a quickly introduction on RF and protocol as ZigBee (1hours) 3) I need support to develop the library(SPI) to comunicate between microcontroller and A7105. (around 10 hours or less) I prefer working face to face so I prefer someone from UK / Italy or Europe.

Blow our minds and design a Sparx Smart System for Pets! Imagine that you are on your way home and you want to adjust the temperature before you get home or turn on the lights or feed your dog, make coffee, play music or unlock your garage door. You reach for your smart phone, open a SparxSmart app and you do your smart thing. Or imagine that you go on vacation and realize that you forgot to turn off the AC (like me). You simply reach for your smart phone, click and voila! You've just saved yourself $200 and also saved the environment from adding redundant carbon emissions. Now, imagine the future - your house learns from you what you like and so when you arrive home, it greets you and adjusts your living space, just the way you like it. Once integrated in our daily lives, Sparx Smart offers convenience, security, energy saving and intelligence. Our spaces of the future will be responsive, adjustable, dynamic and will evolve, wherever we are. Say hello to Sparx, Say hello to the F...

We need you to convert the attached Eagle Files to Altium. The PCB is a simple open source board created by SparkFun. In addition we need you to: 1: Use our own custom silkscreen art and place it into the final file. 2: Add .5" to each end of the board and add four through-holes in these areas, so we can physically mount the board with fasteners. 3: Change the solder mask to black. 4: Radius the corners 1-2mm. 5: Deliver to us a full Altium package, including BOM, 3D renders (top, bottom & perspective views), and output a SW2014 or equivalent CAD file so we can import it into our product's master CAD file. Do not alter the actual electrical engineering in any way. This is a simple file conversion job.

Hello, I need a generic obd interface (hardware + plus software) , which can gather all available information provided by the machine and provide it as an xml. The hardware can be configured to monitor certain parameters like - car speed, car pollution efficiency (via some mechanism), braking or zig zag driving. and store this value and when required push it via obd cable (or wifi) based on configuration.

Temperature control utilizing a 1000 ohm RTD input designed to output to a 3-32vdc solid state relay. The temperature control features power saving functions such as standby (reduced heat) and sleep (self power off) modes, a remote encoder / pot w/ momentary for user input, LED display and other calibration parameters. There should be an output to power (activate) other or additional modules and sleep mode may be inhibited by an external feedback from such other modules. Of particular interest is temperature calibration and related duty cycle settings as described later.

I am looking to create a frisbee for a new game i have invented. The frisbee needs to be approx 175g including the electronic timing device. What i hope to achieve is a frisbee that when thrown is just a normal frisbee, but when caught it activates a variable timer 2/3/4/5 sec. The timer then activates LED's to flash if the frisby is not spinning before the time has lapsed. The electronics need to be moulded within the plastic with access to the battery and the switch for on/off and varying the timer needs to be accessible. Finally the unit needs to be waterproof, sand proof etc. As this will predominantly be a beach game.

Need a talented engineer with demonstrable portfolio of work to help assess a product I have in mind. It incorporates Bluetooth low energy and another communication circuit that relies on the BLE. At this stage all I require is a very simple 'study' on whether the concept can work. From there happy to discuss moving into potential design phase. We can discuss more clearly deliverables when you apply.

My company has an injection pump system that is in need of a complete redesign. The product was introduced in 1995 and it needs a modern overhaul. The system is comprised of a pump, tank, tank base, mixer motor and shaft, plumbing assembly, and dual control switch assembly. Tank and Base are rotationally molded parts. Designer needs to have experience/understanding of the roto-molding process and roto-molded part designs. System upgrade needs will be discussed with designer. Expectations are that the designer will understand our needs and updates, make sure that those needs are met while providing creative, functional and engineered aspects of his/her own. Designer will need to sign a confidentiality and work-made-for-hire agreement after selection.

Hello, I'm designing a board that includes the Atmel SMAD21G MCU and would like to know what's the bare minimum needed in order communicate with the MCU with its on board USB. This MCU is also used with the Arduino Zero and two USB are used there, one for programming (EDBG) and Native. I want to use only the Native one, and maybe also upload the Arduino boot loader there if possible.

I have an Autometer Speedometer that puts out a square wave at 5 volts DC. The faster the speed, the higher the hertz. I need a circuit that will trigger at 175 hertz and above and turn off below 175 hertz. It has to be powered by a 12 volt DC source. Would prefer if possible that the hertz setting can be made variable. I need it to put out a negitive trigger for a relay.
