DIY Power Supply for 5V and 3.3V

I’m currently migrating my old and hopefully interesting projects from my blog www.tiny-labs.com to instructables. I use this power supply regularly to power my embedded projects in the lab. It is very handy and tiny. I’ve used an USB port as power supply for my projects before. Some ICs need 3.3V instead of 5V as Vcc. Therefore I decided to build this small power supply. It uses a range of 7-14V (I use 7V for less power loss) as input voltage and supplies 5V and 3.3V with 1A each. Both supplies can be switched individually.”
