Nice project.Suggestion: Expand it to produce a full-fledged chess clock.
For cutting traces on stripboard, a rotary (Dremel) tool with a small cutting disc is useful. But, wear protective eyewear.
Interesting Instructable, but more detail -- much more detail -- on finding and connecting / wiring up the controller/adapter would be helpful.
The part you describe is the plug, rather than the jack. The jack is the receptacle that the plug inserts into. Otherwise a useful Instructable.

As an alternative to the camera board, you could also use an el-cheapo webcam plugged into usb (using a powered hub). You'd need a hole drilled through the door or apartment wall for the usb cable, of course.Great project and creative use of the 'zero.
Very instructive Instructable, and thanks for posting it. Just one question: I think maybe that a resistor rated at 5 watts will overheat at 1 amp, 12v. Better to use a higher-rated power resistor or paste a big heatsink on the resistor.
These cheap little kit scopes are great for learning electronic fundamentals, but no so much for troubleshooting or practical use. I recall a couple of Heathkit courses that required an oscilloscope -- too bad these little gadgets were not available back then.Note: I built one of these scope kits, the one where you had to solder the SMD ICs and resistors yourself. Difficult, requiring much patience and a fine touch, but doable.
