Welcome. I wanted to provide stripboard layouts I've made to help people new to electronics and even the more experienced get into different aspects of electronics.

I verify the layouts before I post them.

Simple Adjustable Bench Power Supply Stripboard Veroboard

here is the schematic/layout I made up for it - it's a bog standard LM317 circuit which I made a few additions to, I used a 1k multiturn potentiometer and a 121r resistor to give me a maximum output voltage of about 11 volts
you can also use the extremely common 1117 adjustable regulator - it only gives out 800mA but the beauty of this IC is that it's in just about everything (usually surface mount) 

I also added the power supply needed for the display (layout can be found in the blog under "7107 voltmeter")


  1. You really make it seem so simple with your presentation but I find that topic to be really something that I think I would under no circumstances undertsand. It seems too complicated and also really broad for me. I am looking forward for your next post, I will try to get the hang of it!

  2. honestly, when I was new to it I avoided anything that had mathematics in it. if you keep building circuits you'll start to notice patterns and gradually you'll understand it more and more so try not to feel overwhelmed with it, when you notice a phrase like "resistor divider" look it up and read (just a little) on what it is and the knowledge accumulates over time. experiment with components and most importantly of all don't go on forums where they are all talking in mathematic riddles and code - usually they are the people who haven't actually built something in years. if you want to lets say get the resistance of 2 resistors in parallel - put 2 resistors in parallel and measure it with your meter, don't reach for the calculator - it's more fun!

  3. I'm impressed, I must say. Very rarely do I come across a blog thats both educative and entertaining, and let me tell you, you have hit the nail on the head. Your thoughts is outstanding; the matter is something that not a lot of people are talking intelligently about. I am really happy that I stumbled across this in my search for something relating to this.

  4. many thanks for the compliment, really I'm just trying to do something that I know I would have wanted when I was younger, these days there are lots of projects online but they are either arduino/microcontroller based and don't really involve much electronics or it's overly complicated when it doesn't need to be. I'm also really glad people are able to stumble across it
