I would create a merit based scholarship for a local high school senior or a local university for a student or student entering a STEM or even a CS program.
Why merit based? The geek culture is one of self-starters and self-motivation. You want to target someone who has worked hard and whose grades are important to them. So many scholarships are need-based, and having personally had my first child enter college and searching for scholarships, I can personally attest that the quantity of need-based far exceed merit based.
The other benefit is your organization gets the publicity of having a scholarship named after them.
