We have a file we think is in Proteus project format but we dont use this ourselves. We would like the project opening and output to either a pdf to show the schematic circuit diagram, or perhaps converted to a freeware viewer we can read. We dont know what is in the file as we don't have the software ! It might be nothing useful. No other work is required, you just need to have Proteus or something that can read the file. I will send when project awarded.

We want to use a ESP32 Arduino () with 2x Linear Technology ADCs (which has an SPI interface). We're looking for someone to connect us the 2 ADC chips to the ESP32 and read out the data. The data should be sent to a PC using the Serial Monitor in the Arduino environment. The software should also set the output voltage from the onboard DAC to 1.5V. We need you - to buy 2 ADC chips and the ESP32 board (total cost $50) - solder the ADC chip onto a breakout board or similar to allow it to be connected - add a potentiometer for testing - make the correct connections - develop the code so the 2 ADCs can be read independently. WE DON"T JUST WANT SOMEONE WHO SENDS US SOFTWARE!! It's important to us that you demo the actual ADCs working with the board

I'd like create a circuit board similar to the Sparkfun RTK2 (P/N GPS-15136) board with some circuits that I don't need removed. I attached a picture showing an RTK2 board with the pins and connectors that I don't need crossed out in yellow, and the pins and connectors that I do need circled in green. Id like to add the circuits of an HC-05 Bluetooth module to the board. I will supply the board silhouette (See attached .dxf file), you will have to make all of the components fit with-in that silhouette. The location of the power LED is critical and must stay in location shown in the attached picture. The USB-C port should be a vertical female port and should be on the side of the board opposite of the power LED. Location of the USB-C is not critical but its orientation...

...3 4 4 . The DCPJPA consists of a Josephson Junction in series with a DC voltage source, and LC parallel circuit coupled to a long lossless transmission line 5 . A sufficiently long transmission line acts also as an ohmic resistor with a real impedance equal to the wave impedance of the transmission line. A DC voltage applied to a Josephson junction excites in the Josephson an AC current with a frequency proporti onal to the applied Voltage ( f 0 » 483,6 GHz/mV). Applying a DC voltage corresponding to twice the r esonant frequency f r of the LC circuit allows to generate squeezed photon states at f r . The problem has to be treated quantum mechanically under quantization of the LC circuit as well as the transmission line. Pulsed operation of the DCPJPA as well ...
