This project is specifically for the optimization of a Serit SP2636 Tuner using the ST Chip sets STV6110A and STV0903. We have the circuits working but do not perform as good as another similar system that we built. The Serit SP2636 is equivalent to the Sharp F7HZ0169 tuner can. The will require an advanced knowledge of DVBS2 circuit design including external hardware and the ability to optimize the software until the performance of this Tuner PCB matches our previous design. Experience in this area is a must.

The task is simple, recreate the teensy 3.1 with the same number of pins and specs, just make it as thin as possible using thinner pcb, chips on the back, etc. Bidders must provide evidence that they have experience designing and producing electrical chips. We need someone that can take this project through to a working prototype. If after thorough testing we agree that it performs to our satisfaction, we will look to produce the chips in some quantity but what you should bid for is just for building us a prototype.

I need to build a control device for something I'm building. I need to control a stepper motor to feed a wire, and then I need a 1-3 second delay, and then move a separate servo motor, to control a lever. I will build all the other components, I just need someone to provide me with all the electronic components (Arduino, Button, small readout Screen, 1 Stepper, 1 servo motor etc...). Here is what I would ideally like: 1. 2 button control (with a display) - 1st button will start the action (GO) - 2nd button will control count (So I would like to repeat the Go function 1 - 9 times) 2. So when the User presses the GO button, the Stepper motor will feed Slowly lets 360 Deg (I will need to able to change this in the code, because I need to specify the length and speed of the feed, which I need to measure after installation) - This motor dosn't have to be strong at all, I'm just feeding a small wire with this. 3 Once the stepper finishes its move I would like 1-3 second delay...

1) RFID based locking solution (Mandatory) ? Making an RFID based lock. ? Integrating the RFID based lock with the Raspberry Pi/Black Beagle. ? The Raspberry Pi should contain the database of RFID tags, which can be updated via an online server (Azure Web can be used to create the web interface), and we should be able to add the RFID tags directly using the web server. ? We must be able to get the logging data (check in time, checkout time, RFID tag no.) on either a note or excel sheet. ? Remember, only one user should be able to use the locker at any given point of time. Reference to how it may look like:   [obscured]  /watch?v=4lra1Y2RsWM 2) Temperature control ?

We need a working prototype of an kitchen appliance. Professional candidate will start with a document describing how the appliance works and design a circuit, prepare a PCB layout and built the prototype. This prototype involves a infrared sensor, thermostat, fan and a hotplate. This product requires two inputs temperature in Fahrenheit or Celsius and distance in inches or millimeters. Based on input values of temperature and distance, output is varied. Output controls the speed of a fan and resistance to the hotplate. More details about the project are available after signing a confidentiality and non-compete agreement.

I will be in need of someone to help me with a project tomorrow. One of the members in my group had something come up and the remainder of the team members and I have our hands full. We will need someone to help with a shallow foundation design so that we can present Friday. We are all getting together tomorrow at 9:30am eastern and would love to chat over Skype to get some guidance as to what formulas to use and how to go about approaching the problem. We are not asking for the work to be done for us, rather, just some help on how to get it set up so that we can plug and chug from there. We all have our hands full and could really use help for our design project.

Ideally, you will integrate and program the following: Arduino (if you recommend something else, I will entertain idea) with the following components: - Bluetooth - Accelerometer - motion sensor - proximity sensor - magnetic switch - temperature sensor Once put together, this system will execute actions based on specific input from one or more sensors. Example, when accelerometer indicates specific motion, do this, or activate another sensor. Ideally, once a developer is chosen, I will provide list of component types that would be needed. The chosen developer will have the experience to find and select the most appropriate component from any of the dozens of online resources and recommend. I will then purchase and mail them to you, or will reimburse them to you. The final goal is for you to design, build, program a complete product based on my...

We have a requirement for a freelancer to create a PCB Layout for a development board. We have a schematic and a design file in RS-Online's PCB software "DesignSpark". The PCB Layout can be created in DesignSpark or Eagle and it must be to a manufacture's standard so that we can have it made. It must have all masks, screens etc. The Board is to be 2 layer. We have a PCB file already which needs someone with experience in PCB design and layout to look at it and improve it.

We have a room sized about 45-50 square meters, divided into 3 smaller areas. We will have teams of 3-5 players playing in. Idea is that room is kind of magical and dynamic. So people find a wooden tablet with some inscription, then by solving puzzle they understand that they have to place this tablet in particular place on the wall, once they place the tablet on the wall a light will switch on and/or sound will play and/or door will open. Another type of puzzle will be that players with Infra Red remote disguised as an item will open the door. Overall we will have about 12-15 item inputs, controlling about 10-12 outputs. Detailed breakdown of actions players need to do, and what must happen: 1. 5 items are placed/hanged on the wall which opens a hatch on the same wall. 2. Hanging and item on a wall will activate the infrared sensor 3. infrared remote will open the door from point 2(we have the remote) 4. Certain amount of item placed on a scale disguised as a bowl will simultaneousl...

I need a circuit that can be mass produced cheaply. I want to run some 12V 4.8W equipment on a timer. It will run for a 5 min interval and then shut off for one of three user defined intervals. There should be buttons so the user can select different intervals. There should be small LED lights that indicate which interval has been selected. There must be a light sensor that, if selected will cause the equipment not to run at night. There should be an LED that indicates whether this light sensor has been selected to operate. Input: 120 V ac Output: 12 V dc Button one: Selects 60 min "off" interval Button two: Selects 120 min "off" interval Button three: Selects 180 min "off" interval Button four: Selects a light sensor which can cause the whole thing to stop operating at night.

Need to design a high speed counting circuit to detect the time difference between two separate signal pulses with 1nsec resolution. The leading edge of signal 1 pulse should start the count cycle, and the leading edge of signal 2 pulse should terminate the count cycle. Please advise on most appropriate design. I have been envisioning synchronous counters clocked at 1 Ghz with a total of 32 bits, which could pass data through shift register(s) for transfer of data to unknown interface (possibly FPGA). Counting cycle could be enabled with signal from a latching comparator, and disabled by the signal of an additional comparator. Once the count is collected, the cycle is reset for the next set of pulses. I have data sheets of circuit components that may work but am uncertain if they are the most appropriate selections. Deliverable includes selection and refinement of circuit components with associated BOM, generated circuit schematics, and associated PCB layout files. Phase 1 - Select...

Hello, We are looking for a router that can work in ad hoc and infrastructure mode together. It will create two wireless networks. One mesh network to connect to other wireless routers and another network to connect mobile devices to the internet. Each router should boost/extend the signal. Not sure which one is the best (5 Ghz or 2.4 Ghz) but the system should operate within the ISM 863-870 MHz range Europe and other. More details in private message. Thanks MAGUIDO
