I’m thinking of creating a timing device for Teonn, specifically to time the five minutes required for ritual casting, as it can be quite odd to pull out a watch, and distractions can cause problems when trying to count to 300 seconds.
My idea is to make an electronic device that has a small switch, that upon activation counts to five minutes, and then sends a signal, most likely it lights up some LEDs or something, and these remain on until the switch is reset to ‘off’.
Now, this too on the face of it is very anti-immersion, so, my plan is that this device be incorparated into a bracer that I shall be wearing upon my left arm. The switch will be disguised, and the bracer will be designed such that the ‘lights’ are actually the spirits appearing in viewable form upon the runes on said bracer. A second switch for an extra minute when casting upon another would also be useful.
If such a device could be designed, it could also be incorparated into other channeller’s ritual foci or gear.
I’m not at all savvy with electronics or anything, so my question to all is simply: how can this be done?
