Cheap high voltage capacitor chargers

Could i use cameral flash circuits to charge a 2100v capacitor? If yes how, if no could i make a cheap and very simple one to do it? I dont have alot of knowledge with arduinos or electronic components that require programming but im ok with most other electronic components so if i have to build my own i need a way without those parts or i guess ill just have to learn them.

Arduino alarm clock help!

Hello I am trying to make a pressure switch for my alarm clock where when I stand on it for a certain amount of time the alarm will stop. I've never done any arduino work before so I was wondering what board would best suite me for this project. I found this one but I don't know if it will work. https://www.gearbest.com/development-boards/pp_629... I also found some code online that I think would work. Here is the link for the code: https://arduino.stackexchange.com/questions/1193/a... Also would this be how I would set the entire thing up?Do I need any resistors? What type of power supply would I be able to use?
