I am trying to build tinhorns timer and was wondering what schamatic to follow, the one that is linked here on jesses site or the one that is with the picturestinhorn posted? I have noticed that they are different. I built one following the pictures but it won't work when I test it like he says in the picture, the led won't lite and now voltage .
 Does anyone know if you could put a higher capacitor for C2 and then put a resistor bank and DIP switches for VR1 ,to give you different delays?
  thanks
