As previously announced, we’ve replaced Chhavi’s USB Micro B connector with a USB Type-C connector. We’ve been testing a prototype, and can now confirm that it’s fully functional! We are very happy that backers have been taking an active interest in Chhavi. Please continue to reach out if you have questions or suggestions!

Electronics was just all about engineering at the beginning, but the hacker community turned this industry into an artistic creative fun thing. We, Vicharak, are particularly interested in developing various kinds of hardware which will eventually serve people and hackers. We have already launched our first campaign with Maypole and some more cool projects are in the pipeline too! We want to try every possible electronics segment which can be hackable and make it more easily hackable. Our main goal is to develop simple solutions with major features.
