I recently bought two of the MK133 quiz table kits, and have a question:
What modifications would it take to power this board from a 12V source instead of a 9V battery? Also, in so doing, what would be the new power restrictions for an external indicator? Another question, is there a modification which could be made to increase the current draw maximum of this external indicator?
There are many intriguing devices out there which run at 12V and I’m inclined to build a kit to make use of one. I am electronics savvy enough to make modifications, but just don’t have the time to try to analyze the entire circuit. Thank you in advance.
