What do you do once you have played around with development boards and found their limits? When we went to the moon with 2 MHz and now you can get a 240 MHz chip for a few dollars, what is stopping you from making awesome things?

In this video I’ll show you how to go from a simple development board to your own custom circuit board. You’ll learn how to skim a datasheet, clone a working design, modify it, and eventually build a device that’s completely your own. You don’t need a degree or a lab. You just need curiosity, some basic tools, and the willingness to build.

Topics covered include:
- why development boards are great for learning but can hold you back
- how to recreate a dev board using the manufacturer’s documentation
- how to design and assemble your first custom PCB with a microcontroller
- how to test, debug, and verify that it works
- how to design an enclosure and make a complete product

We live in the future. You can make your own devices for the price of lunch. If you’ve ever wanted to create something real, this is where to start.
