    I am looking for a freelancer who can help me set up the example code for Chronoamperometry and Square wave voltammetry on a potentiostat. The specific potentiostat model that I am using is Model A. The potentiostat that is currently being developed consists of an ESP32-C3 processor, with integrated WiFi and Bluetooth 5, and an Analog Devices AD5941 (which is compatible with the AD5940) analog front-end that is specifically intended for electrohemical and biological measurements. Analog Devices supply a sophisticated library with the AD5941 Evaluation board, including many examples of firmware for specific applications, such as Cyclic Voltammetry (CV), Square Wave Voltammetry (SWV) and Chrono Amperometry (CA). The example code for the above three measurement methods ...

    I look for someone who can help with project based on this paper: Aim is to get Potentiostat based on PSoC (CY8CKIT-059 PSoC 5LP Prototyping Kit) with additional electrochemical technique for SWV (Square Wave Voltammetry). Or, If not possible, create Potentiostat only to Square Wave Voltammetry based on PSoC (CY8CKIT-059 PSoC 5LP Prototyping Kit).

    Multichannel potentiostat circuit S'est terminé left

    I need a multichannel potentiostat circuit. It is essentially an analog switch to turn on or off drive voltage, and an op amp for current to voltage conversion. I was thinking Quad analog switch and 4 op amp chip. Total of 16 or 32 circuits. The PCB would need to interface with a D37 which drives TTL control of switches and a D37 which connects to my analog input +/- 10V, also an output connector which goes to our electrochemical cell. The cell has a matching number of electrodes say 16 or 32 and runs at a maximum of about 5 mA per electrode. current to voltage response of about 1 ms. Thanks EP

    My company had an electronic engineer for 3 years, but he left without giving us all the documents. Now, we have to make an update of our board, but he lack a lot of details and information. The project is to make a potentiostat board (10 channels) for measuring ionic electrodes (like pH electrode). It sounds easy to do, but 3 different european electronic firms didn t succeed (the electronic has to be very precise, with high quality components, a lot of shields, ...) We can provide all the schematics for the PCB production, pictures of the working board and few other files (no idea if they are updated or not). The project is to deliver working boards (at least 3), with all the documentation, the firmware, a web interface (there is an onboard server) and all the instructions to upd...

The code from PSoC 5 should run without problems, but Bluetooth and UART communication platforms need to be coded. Next, instead of the GUI being visualized in the computer, I want an app that can communicate with the potentiostat in order to visualize results in cellphone. The GUI is currently written in Python, so it will need to be translated. please bid if you have experience with Psoc boards and andoid app developpment

    Hello, I'm building lab-scale solar cells. At the moment I have to test these solar cells one by one, which can take me a whole day to do a single batch. I'm looking for a way to measure 32 cells simultaneously. Each cell would ideally have its own counter and working electrode. Output voltage range should be > 3V, current measurement range from 1 uA to 10 mA. The project would include building the setup, programming and GUI.

    We have a power supply that goes through a R1 and a variable R2 resistor. We can adjust manually its Vout with a potentiometer. Our goal is to maintain Vref stabilized to a preset manual value SET Vref (with a potentiometer) despite the change of load (R1, R2, R1+R2). At this point you have to understand that Vout is not the Vref. Vout has to be adjuste...manual value SET Vref (with a potentiometer) despite the change of load (R1, R2, R1+R2). At this point you have to understand that Vout is not the Vref. Vout has to be adjusted as much as it has to maintain Vref equal to our SET Vref value. This can be achieved through manual mode (manual adjustment of Vout until Vref=Vset) or automatically which is the main issue. (It is something like a voltage potentiostat but without the circul...

    I am looking for someone who would design a prototype (schematics + code) with an Arduino to regulate output voltage based on input measurements (you may get more information if you Google: potentiostat). This has to be done through the same two pins, so input and output terminals are the same. The logic is an analogy for battery charging, so the output voltage supply is interrupted in short intervals to measure the input voltage potential and conductivity which are the base for output voltage regulation. I already have MCP4725 and INA219 breakout boards which could help with that. The output voltage range is between 2-10 V and the output current is between 0-50 mA. I do not know the exact relation between the input and output, so code has to be flexible and allow me to experimental...
