This is my Maxitronix 30in1. It's an electronics project lab kit with thirty projects to make for the purpose of learning electronics. I am in the process of working my way through it on my video blog In The Lab With Jay Jay, you can find out more below.

Projects

Here is the table of projects which have been done or are in the process of being made. As I make progress I will add new projects at the bottom of this table. The links to the latest videos go in before those videos are published so you might have to wait to see some of the latest videos until the day they are released.

Scans

Following are some scans of the pages in the manual. Each project page has the scans for each project, these scans are just for the front and back matter.
