Overclock Your Mailbox. HackerBoxes is a monthly subscription box full of surprises for electronics hobbyists, computer enthusiasts, makers, and hackers. We’ve all seen a cool project online and wished that someone would produce PCBs and kit all the parts so we could easily build one for ourselves. How about one every month? We work hard to create monthly HackerBoxes that we would be thrilled to receive. Surprises for electronics hobbyists, computer enthusiasts, makers, and hackers. Each box generally includes a primary project, parts or modules, tools or supplies, and promotional items or swag.
