    There are only 21 soldered connections in the circuit, 17 component pins and 4 input and output connector pins. That's a pretty small number, so this should be pretty easy to do on perf board if you already know how to solder. If you really want a pc board, several quick-turn prototype shops have free layout software. I've never used that stuff because I have a pro-level system at work, but they get pretty good reviews. You might start a separate thread asking about them to get more focused responses. There have been other threads regarding free layout packages.

    Hello All,

    I can't believe its been almost 5 years since this thread started and I have still got half of the components in the garage to build the circuit and have been "going to" grab the rest when I get time. O well, life gets busy I guess.

    Hoping to do something with this soon and provide some feedback.

    How come it has been 5 years since it was started in Aug, 1, 2016?

    Haha, just realised I was looking at the membership date of AnalogKid and not the thread date. That feels like a more realistic time span. I need to get some sleep lol.

    Reviewing the schematic in post #17 -

    To increase the time between interruptions to 1 minute, increase R1 and R3 to 33K.
    To maintain the interruption at approx. 0.1 second, move the anode of D1 from Q7 to Q6.
