I like to roast my own fresh peanuts , I require exactly 15 mins in the oven at 350oF, the same goes for my muffins for 20 mins and a few other short periods. It has to be just right but Iíll be darned if I can set up that oven timer properly. I was getting fed-up with overdone peanuts so I found this dandy little circuit and added to it and changed a few things stuffed it in a little box and take it with me to watch TV while my peanuts are in the oven. It beats paying $35 to $50 for an alarm that I can't hear anyway. I split the schematic in two parts to fit the page. I think it is self explanatory and easy to read.
