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...

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 ? Will be using a simple exhaust fan connected to a relay. ? Measure the temperature using a temperature sensor. ? The raspberry pi should signal the relay to turn on the fan when temperature inside the locker goes above 77 degrees Fahrenheit. 3) Capturing videos and streaming our Internet. ?

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...
