/diy/ - Do It Yourself

Rate my first project. I ran out of good lead based solder and found a big roll that just says ``Solder`` and the manufacturer`s name and it`s terrible.
It`s a linear power supply. It goes from 0 to 24 V, and I haven`t settled with a current capacity.
I saw some other anons here saying things about big TIPs 127 or some other chonky transistors but I only had BD140s here, I`ve used 4 of them, each with it`s own diode and base resistor.
The voltage reference is a 7812, which will be used to power 2 fans in the box. The yellow heatshrink is covering a inline resistor (I`ll install the fine tuning pot later) because I`m naugthy like that.

Next project is a Ozone maker thing.
