The 10KΩ resistor on the 50K pot and the 47KΩ on the 200K pot are to keep the resistance from going to zero.That was one board. i removed the 10k resistor from the delay on because i did not need it. the 50k pot had enough delay. i did make another where i included all the components. im just so puzzled by this.
yes. all work.Do the bread boards all work?
Thank you for this.We will walk through this step by step as I get your responses.
Plexiglass is flammable and starts burning at temperatures from 450 ° Celsius.(Plexiglas) as an electrical enclosure is not a great idea.
I took a small sample of this outside and hit it with a heat gun. it would not catch fire but it did warp significantly. I applied the flame from a blow torch and after about a 1/2 a minute it stayed lit and burned on its own. The manufacture says this will form droplets of burning plastic but this did not. Instead it burned more like a candle but with no smoke. it appeared to be evaporating. After 2-3 minutes I extinguished the flame and it had virtually no traces of charring. I also took a UL approved electrical box cover and did the same. This product would not catch fire but it produced a thick black intoxicating smoke. My father said the shipping yard his father worked at was under a military contract. I did read that there are different grades of Plexiglass but I would not know what grade this material is.It depolymerizes into volitile monomer and burns easily
Its been a while since you helped me make this Workshop circuit. Since then ive gained some experience using PCB software. Ive made (with help from this group) a Timer circuit for my closet and had PCBs manufactured and they look and work great. Ive even created PCB parts for my projects. Many of them for the workshop circuit. it took a long time but it was worth it. I intend on having 5 boards manufactured for my shop but before i send off the project I would like you to take a look at it and tell me if anything is wrong. When i originally did this project i was unsure how to properly wire a Variable Resistor. I used only 2 of the three pins. I learned of my mistake when working on another project. this is probabally why the timing of my build was not as you documented it.Congratulations for fighting through to a success.

I UPDATED THE SCH FILE
what do you mean? the entire project and all of the documentation are in this post.write it up for everyone else.
Thank you. I know the pots configuration. I have them orientated so the rotation is logical (clockwise goes from 0 to 50k). So do i have them configured correctly is the next thing to figure out.You can set this by changing the connection from the wiper to one of the other of the two pins if the rotation isn't correct.
