Along the way I will show you different reverse voltage protection techniques and show you their advantages and disadvantages. This way you will hopefully never damage your lab bench power supply like I did.

More information (parts list, more picture) on Instructables: http://www.instructables.com/id/Build-your-own-Variable-Lab-Bench-Power-Supply/

In this video I will show you how I combined a LTC3780, which is a powerful 130W Step Up/Step Down converter, with a 12V 5A power supply to create an adjustable lab bench power supply (0.8V-29.4V || 0.3A-6A). The performance is quite good in comparison with other models which cost around the same.
