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.

Battery Simulator With Voltage Sag And Bar LED Indicator Stripboard Veroboard Layout


This is sort of a request - I was asked if I had a layout for the KAT Deacy Amp Battery Simulator which of course I don't but I thought "it can't be that hard to design one"
the KAT one has a "voltage sag" control on it to simulate the various battery discharge states so I designed that into it as well.
I thought however; I would go one step further though and include a battery state monitor too which is configured to show the working voltage of a 9 volt battery.

I thought it would be a good idea to do this little project because it has many uses outside of the Deacy amp - you can of course use it to sag the voltage of any 9 volt device such as guitar FX pedals which I know people like to do.

As you can see - I tested this using my constant current load set at 100mA and even pushed it to 200mA but I didn't want to go too far because I couldn't be bothered to find a heatsink. you can get upto 1.5 Amps if you use a decent heatsink.
