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...

The goal of this project will be to update a design of a PCBA for a 2500 mAh LiPo single battery power bank. PCBA specifications: Hi, we have not found a part number of the main IC. We are now choosing a provider to update this design to a new IC. We'd like the resulting design: - to reuse as much as possible from the existing design - to fully comply with this list of requirements: 1. Input: DC5V 1A, so that battery charges at 1Amp rate 2. Outputs: two independent outputs, DC5V 1A. Connection of an external device to one output automatically blocks the other output. 3. Built-in protections for input and outputs: 3.1. overvoltage 3.2. overcurrent 3.3. short circuit 4. Built-in protections for battery: 4.1. Overcharge 4.2. Overdischarge 4.3. Overcurrent 4.4. Overheating 5. Battery charging/discharging: standard 3.7V LiPo battery charging cycle, 2500 mAh battery (we will provide the samples) 6. Simple shake sensor: activates LED indication. Example:   [obscured]  /Electron...

We are looking for a talented FPGA programmer to help us implement a low noise (<10nV/(rootHz)) lock-in amplifier for heterodyne detection of sideband signals. Carrier frequencies range from 0.3 to 1.5MHz. The lock-in amplifier must have the ability to generate signals at specified frequencies and demodulate signals at the sum or difference of two frequencies (FM/heterodyne detection). Your job will be to develop a working prototype that does the following: 1) Takes in signals via a high speed, 16bit ADC 2) Generates a sine wave with programmable amplitude (ranging from 0 to 5V) and frequency, f2 = (1 to 1000Hz) 3) Demodulates the signals at two frequencies f1+f2, f1+2f2. f1 is determined from the DAC input. f2 is the frequency generated in step #2. 4) Outputs the RMS amplitude of the two demodulated signals via a low noise, 16bit DAC. We have an ADC and FPGA eval board already chosen, part #'s AD9268 and HSC-ADC-EVALCZ from Analog. You will need to help us choose the DAC and fi...

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...

Looking for a freelancer/company to help us design a circuit for a physical game for kids, involving lasers, mirrors and light sensors. The game is a sort of puzzle where the player needs to make a laser beam reach a light sensor by moving small mirrors to reflect the light. It needs to be hooked to a raspberry pi or alike to control the game logic. The game size is approximatively 4m x 2.5m x 0.5m. You will help us translate our concept into a working installation, define what is possible or not, select the components and design the circuit. We will also need wiring diagrams and specific instructions to provide our local contractor. Optionally, you could also provide us with some basic code to run the circuit.

This will be a taxi security cam. It will take photos at certain intervals, store them temporary in the SD and push them to internet to be accessed afterwards. To simplify the schematics, the camera clock should be provided by arduino. I would like to use the OV7670 non-serial camera as it could be found relatively easy in Argentina. And arduino mini or micro. If possible. There are some examples of this camera with arduino on the internet Thanks
