Why do they buy compuers and give them to children? Woudn't it be better to give the money to the students and require them to buy a computer that meets the requirements, that's what we do here in Norway though this is at high school level.
Well I know one way that could work, but you'll require some items:
- One of these:
- A powerjack that fits into the R-Pi.
- Some form of cuttation device, possibly a knife.
- Tools to connect the powerjack to the USB power supply.
One thing that you could do is add a simple app on the front page where the visitors could choose how many they would like to buy, seperate counters for A and B of course. This would be a simple and noncommiting way of finding out how many you should have.
