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...
