At first glance, this solar-powered “DIY Calculator” looks like a blank notepad, but users can personalize it by doodling on it.
Users will have to make out where each button is before putting pen to “paper”, but this is a great accessory to have during boring lessons or meetings.
Although prices are not out yet, this calculator serves to keep those creative juices flowing, especially when you are bored.
See what you can do with it below.
