    • RE: Cyclic voltammetry on 0.1M KCl

      Yes. I ran the tests with ascorbate. 0.5V/s seems to work fine, 50mV/s is very slow, took like 5+ min for 5 cycles.

    • Cyclic voltammetry on 0.1M KCl

      I had the rodeostat hooked up with the CH Instrument counter electrode and Ag/AgCl reference electrodes. I made the same carbon paste electrode shown in the blog. https://blog.iorodeo.com/making-a-carbon-paste-electrode/

      Next I placed the electrodes in the beaker and ran cyclic voltammetry on 0.1M KCl. 100uA, -1V to 1V, scan rate 0.5 V/s. I obtained a graph that looks like this.

      Is this correct?

      Ran two cycles but the voltammetry doesn't overlap

    • RE: Cannot connect to Rodeostat with web app software

      Hi Will

      Its me again from SUTD. I tried the same software and settings on the Acer laptop. This time, the Rodeostat is able to connect to the webpage, it stated sucess:true. However, I am not sure why my surface pro3 is unable to open the port.

    • Cannot connect to Rodeostat with web app software

      I have the Rodeostat connected to the USB on surface Pro3 running on windows 10. Ther serialport bridge software is running and connected to localhost.
      The webpage is opened with Firefox. After connected to the serial port, the option COM3 (only one) is selected, and the toggled to open the serial port.

      However, the firmware version and hardware variant does not appear and the message

      Message from serialport bridge reads:
      { "open": { "msg": { "port": "COM3", "options": { "baudrate": 115200, "timeout": 10 } }, "rsp": { "success": false, "serialPortInfo": { "portName": "COM3", "baudRate": 115200 }, "ports": [ { "device": "COM3", "name": "COM3", "vid": "16C0", "pid": "0483", "manufacturer": "Microsoft", "serialNumber": "2741590", "product": "" } ] } } }

      Then I tried to run the tests, but nothing shows up on the screen. Also tried with Microsoft Edge browser but the same message appear. What is the issue with the connection?
