Detaching flex sensor from the board and increasing Qwiic cable wire length #3

Closed adildsw closed 3 years ago

adildsw commented 3 years ago

Hi @WHC2021SIC/sic-chairs!

The Flex sensors provided to us come in pairs of two attached to a microcontroller. However, for our application, we needed the flex sensors individually, as was specified in the WHC 2021 SIC Website.

Is it okay for us to extract the Flex sensors from the Sparkfun Qwiic Flex Glove Board and solder it with extra wires?

Also, in another similar issue, one of our applications require a lenghtier cable connection to the pulse sensor. Is it okay for us to cut one of the Qwiic cables and extend it using extra wires?

Looking forward to hearing from you!

Hi @adildsw and @WHC2021SIC/team-on-body-gym team,

We @WHC2021SIC/sic-chairs have discussed your request and agree that you can cut and extend your flex sensors and Qwiic cables. Please be aware though that we won't be able to replace these items.

Hi @ChristianFrisson and @WHC2021SIC/sic-chairs,

Thank you so much for allowing this, we really appreciate it! And yes, we take full responsibility of these hardware components and understand that WHC won't be able to replace these items.

On a related topic, we had another question. The hardware architecture for our project, as suggested by @WHC2021SIC/sic-chairs is as follows:

Original Sensor Configuration

Now, since we are allowed to extract the flex sensors from the flex glove board, do you think instead of reattaching the flex sensors back to the board with elongated wires, we could instead connect the flex sensors to another ADC, similar to what we are using for the FSRs? The modified configuration would look something like this:

New Sensor Configuration

Since an ADC has 4 input channels and doesn't require soldering, this would not only be safer to implement hardware wise, but also easier and would assist in reproducibility on your end. Moreover, it would also allow us to use 1 board for all the 4 flex sensors instead of 2.

We know that we are provided with only one ADC board. However, do you think this would be within the realm of possibility that we could use one of our own ADC boards of the same make as the one provided by the WHC and go ahead with the new architecture?

Hi @adildsw and @WHC2021SIC/team-on-body-gym,

We @WHC2021SIC/sic-chairs have discussed your request and think it is fair (with respect to other teams) to let your use the flex sensors with your spare ADC board, since with these changes your project still makes use of hardware proposed for the SIC challenge.
