About: Always loved electronics. I like to reuse parts or componets and I Love to be part of the Instructable community.
Here is a small video showing my latest project. It is a small bench power supply that can adjust with precision current or voltage.
It is the first time I use an aluminium enclosure, so I decided to engrave the labels and symbols. I use 10 turn wirewound potentiometers to be able to adjust the voltage or current with precision. I power it with a laptop charger, like the my Mini Adjustable power supply . This adjustable power supply is larger than the "Mini" I made, but it is a lot easier to use and has a few other advantages. I will be posting an Instructable with detailed instructions of how I've made it.
