Filament Alarm From Solder Practice Kit
Description
I Had An Old Elenco Soldering Practice Kit Sitting In My Closet That I Wanted To Do Something With, So I Made A Filament Alarm From It. The Filament Feeds Through The Hole On The Side And When It Runs Out, The 2 Leads That It Was Separating Will Connect Setting Off The Alarm. There Is A Hole In The Top To Reach The Volume Knob Located On The Board. I Had To Do A Bit Of Trimming To Get It All To Fit And Needed To Tape The Plates Together To Get It To Work Reliably. If I Revisit It, I'D Make It So They All Snap Together. You Can See A Quick Demo Video Here: Https://Youtu.Be/Nyvrwvzckmm
