I ordered some things from the UK firm kitronik kitronik so and have the clearance section so I bought a couple of power plugs which were always in small but the main thing was this picture so super capacitor kit so it's quite simple click but it looks like it might be entertaining I wanted to play with super caps for sometime and you see it comes with quite good instructions very thorough in fact compared with the sort of normal Chinese things I've put together so we have a schematic here so basically the core of the of the kit here is the LM 393 which is a comparator so there's two voltages have been set on the inputs they're two threshold voltages and when this input voltage from the super cap reaches the two thresholds it's going to light these two LEDs one after another so basically the LM 393 is allowing us to charge the super cap and and see when it's fully charged and then there
