Thanks for your instructions. Especially the breadboarding images. You have taken lots of efforts to make this instructable page. Thanks a lot for this selfless commitment to spread the knowledge. By the way I replaced the N2222A with a MJE3055T which has a better gain, although I needed a heat sink else it got heated very soon. But the results were astounding as compared to the N2222A.
Great Cube. Enjoyed making it. Thanks.
Great cube. Thanks. I was able to complete it. The assembly is a bit tricky but satisfying after it is done.
