An anonymous reader writes "I am tasked with developing a service project to teach students in a Bangladeshi village how to type. The school has about 500 students, 12 computers donated to them in 2006, and a limited electricity supply. The students will be given job placement opportunities at a local firm in the city once they reach a certain proficiency. Therefore, we are trying to teach as many of them typing skills as possible. The problem: limited electricity, limited computers, many kids. I have some additional funding collected through donations. Instead of buying more computers, I am looking for a cost effective way that does not need a steady flow of electricity. I realize that to teach typing, I do not need a computer. I could achieve the same using a keyboard connected to a display. A solar powered calculator is a perfect example of a cheap device which has a numpad for input and an LCD for display. But so far I have not come across a device that has a qwerty keyboard and an LCD to display what's typed. I know there are some gaming keyboards that have LCDs built in but they are quite expensive. I am aiming to build a device that cost below USD 50. I considered using typewriters but they are in limited supply on the market. I also considered OLPC but it is double my anticipated budget. Do you have other suggestions?" Considering that (at least in China) sub-$50 Android tablets with capacitive screens are already here, I wish the Alphasmart line was cheaper, but apparently it currently starts at $169.
