I wanted to tidy up my workbench, so I decided to build a prototyping stand for my electronic projects. A big advantage of this is that you can carry the projects around without breaking them. I also want to use it to teach my kids electronics. That is why it must be easy to use and look nice.

The prototyping stand has an integrated power supply which supplys 3.3V and 5V. It has enough space to work comfortable because it features two breadboards. And it features banana sockets because they look cool.

The power supply is an cheap hw-131 board (2,50€ on eBay) which has short circuit protection. Apart from that

• some M3 screws and nuts
• four banana sockets
• two breadboards
• an on/off switch
• a green LED
• a 9V battery and a battery cable are needed.
