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...

I am looking to improve conventional HFAC (air conditioning system) Controller. I need design for the board and prototype made if needed. The system will do the following Input 120VAC and 240VAC / Output 24VAC Board will receive input from 8 thermostats which send 24VAC signal to Board When Signal is received the Board needs to start (using relay) High Voltage Motors (blowers) and in some cases also send 24VAC to another device. Board needs to be connected to Network using Ethernet Cable All of these rules need to be configurable in some software utility Board needs to be connected ready OHM from Temperature sensors (8 of them ) Board needs to be able to receive information from network for each 8 zones about Requested temperature. Board needs to make decisions as to if temperature is ABOVE requested then DO THIS if below THEN DO THIS. Programmable on board. This is the first time I am designing a board so I will need assistance and iterations.

Need to design an Ultrasonic motion sensor and notfyer to be installed in the wheel arches of a car. Need the design to be able to build the unit myself. This project is to avoid parking tickets my creating notification when a parking officer marks my car tyres with chalk. When the parking officer moved their hand under the wheel arch the movement will be detected and I will be notified by text, email or key fob beeper. ( Range required approx 500m and within a building) The sensor could be mounted under the wheel arches ( the 2 front) or on the body of the car above the wheel arches. Ideally the components to build the project will be less that $250 and be available from online sellers. I imagine Arduino or rasberry pi will be the best options for a controller. Ideally the unit will be battery powered so I dont have to wire it into the car. With the bulk of the unit being attached to the dash an an on off switch so I can arm the unit when I get out of the car. Ideally the plans ...

Hi, we want to use an IR sensor for a medical application (temperature between 25-45 C). We're interested only in the temperature change of the target (we're not interested in the absolute temperature itself). We would like to know whether there is any adaptation / optimization we can apply to the camera / readout circuit in order to improve its temperature difference accuracy? (compared to the usual case where the circuit is optimized to output absolute temperature, and then we derive the images, frame by frame, to obtain the change in temperature). I need you to support the solution with a reference and/or a calculation that would show the expected improvement in performance due to the optimization for temperature change (compared to the usual systems that are optimized for measuring absolute temperature). Best regards, Gil
