115 did electronic scouting last year, and our overall cash investment was close to $0. A couple members spent several months on an app that would use QR codes to transmit data to a central phone. "Slave" phones would take data for a match/robot and generate a QR code that could be decoded into data. The "master" phone would quickly read all the QR codes post-match and put them into a spreadsheet.
As a result, we just used the students' Android phones and an app, so we didn't need to buy any tablets or phones. However, I believe we spent many more hours on this approach compared to just using a pre-made app. If you have people with the skills twiddling their thumbs, electronic scouting doesn't need to be difficult.
