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.

20 Second Handwashing Timer (for Covid-19) stripboard layout


quite a simple project, during the Covid-19 coronavirus outbreak, one of the pieces of advice we've been given is to wash our hands for 20 seconds. so here's a timer circuit to help you do that.

"sw" is a push-to-make momentary switch, once you press the button, the LED illuminates for about 25 seconds (I added a few seconds to the timer to allow time to put soap on your hands). then just wash your hands till the LED goes off.
pretty good way to make sure your kids are washing their hands for long enough.

Stay safe.

    1. because my "policy" is to build everything before I post it, it rules out certain things;
      in this case I couldn't do it cause I don't have any spring reverb tanks

  2. Could you explain the function of the diodes and why you are utilizing a mosfet and a pnp to drive the led?
