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...

Create 3D model in CAD software and output into a plastic 3D model. Smarty 3D Printing project. Dimensions: Height (not counting antenna): 9.0" to 12" Outer Diameter of upper body section: minimum of 3.0" (if proportions are kept the same as the jpg drawing it will satisfy this requirement. We are located in the Bay Area in California.

End product should be a high-resolution and photo-realistic 3D rendering of back wall and floor with fireplace, mantel, wood/fire in fireplace. A very simple rendering but must look like it was photographed and similar to the attached sample but without the tree, no rug, no furniture, no stockings, no floral/garland, no vases, no chalkboard, no ceiling (have wall extent to the top, left and right)...simply floor, wall, mantel with fire screen, wood and fire. I'd like the ability to have a variety of revisions to get to the final product but to start, replicating the scene as I've described above and shown in the attached is step 1. If this process looks great, there are other opportunities to do more work and add in other elements. Please only submit bids if you are able to pull off renderings that look realistic, like we photographed the room and didn't render it.

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...
