Back in the swing of things after a good holiday break. Worked on hooking up a load cell for readings! #ChangeHowYouRoll

Soldered some strain gauges so we can put it into analog input tomorrow and eventually create our full wheatstone bridge within the roller. #ChangeHowYouRoll

Hooked up the strain gauges to our arduino and now are working on getting code to test their data output. #ChangeHowYouRoll

Got our force sensors to read out to analog values. #RollOut

Troubleshooted our strain gauges this morning with our mentor Mr. Chin. We are now able to get accurate readings again and are waiting to see how super glue will dry on the inside of our roller to put it all together. #ChangeHowYouRoll

Finally glued in 1/4 full wheatstone bridges of strain gauges and were able to get accurate readings by flexing the roller. #RollOut

We are so happy to be able to present this promotional video for the Windham High School event, Shark Tank presented by Patrick Kaplo. If you weren't able to attend this year, make sure to check out the video to get feel for the event! youtube.com/watch?v=POQVNJ…

Worked on figuring out ways to best make Rollout one cohesive roller, and begun app design! #ChangeHowYouRoll

Put together and troubleshooted a second wheatstone bridge connected to one HX711 amplifier. #RollOut

Tested the A+, A-, B+, B- pins for shorts to figure out why our second bridge is not giving readings. #RollOut

Worked on our arduino software today to try and read multiple gains at once. #Engineering #ChangeHowyouRoll

Finally back after a well-deserved February break. Getting back in the swing of things today and then meeting with our mentor, Mr. Chin, on Thursday to troubleshoot our strain gauge readings.

With help from Mr. Chin, we were able to get readings from both of our first two bridges. Soldered and connected the second two bridges to eventually get readings from the other side of the roller. #RollOut

Troubleshooting day here with Rollout. Using a voltmeter to test A and B pins on our amplifier & soldering a new amplifier for extra bridges. #ChangeHowYouRoll

Worked on app design today to give our users an engaging RollOut experience. #ChangeHowYouRoll

Labeled some wires to make putting everything inside the roller just a little bit easier. #RollOut

Today we are installing FTDI drivers to get Ardunio nano compatibility & we FINALLY got the strain gauges for the other side of the roller! #ChangeHowYouRoll

Worked on creating a plan for the following weeks and did some research on getting drivers to work for a nano on a Mac to try and complete milestone 3/5. #RollOut

Simultaneously working on our app design & troubleshooting and ordering new arduino nanos to eventually get cohesive functionality. #ChangeHowYouRoll

The Arduino nanos and Arduino uno came in so we will now be able to put together our entire roller and get started on the second side. #ChangeHowYouRoll
