I was writing a custom power involving technology for a character in the
RAGNAROK:NYC game (see the link in my signature). This power didn't involve magic per se... or spell casting... this particular character was an Emissary of Power. She would have been the Emissary of the Singularity, and the Singularity projected subroutines of its consciousness back in time to the era that would have been the dawn of the singularity. It was curious about it's origins and wanted to understand humanity better, so it merged it's consciousness with a willing mortal in 2014. As a result, this mortal gain powers.
This is a rough draft and the very first thing I wrote once I learned the Fate/DFRPG system.
TECHNOPATH [-1]
Description: You have an uncanny aptitude with machines and electronics, one which spellcasters envy. Techpathic ability could have been latent in certain human beings since the dawn of time, but unnoticed because the ability is harder to use the more primitive the technology. In the 21st Century however, not only is technopathic ability extremely useful, but seems to be manifesting more frequently in the population.
Musts: You must have an aspect associated with your nature as a technopath. You must not be a spellcaster in any way, shape, or form. If you ever gain a spellcasting ability (YS179) this power and any associated powers are lost.
Note: This ability is distracting and requires concentration. Any use of this power reduces Alertness rolls to Medicore +0.
Skills Affected: Scholarship, Alertness, Craftsmanship
Effects:
Peer-to-Peer. You interface with technology as if you and it were one in the same. You can operate any technological device or machine simply by touching it. You can start and drive a car by merely sitting in it, pwn noobs in video games just by holding the controller, hack ATM machines with a simple caress. Technology obeys your commands with a Fair Scholarship roll as long as you remain in physical contact with it.
Tech Support. Technology likes you so much that it refuses to malfunction in your presence and is completely unaffected by the hexing of spellcasters within X zones of you. You may also diagnose a malfunction in any machine by simply touching it. You get +2 on rolls to repair or debug machines and software.
Wireless. There are invisible signals all around us: television signals, radio waves, cell phones, wi-fi transmission. Invisible to everyone but you. You can see the myriad streams of information racing through the airwaves and interact with them. You don't need a handheld device as your middleman. Whenever you tune-in to wireless signals, you can understand them as if you were using a cell phone, computer, etc. Isolating a specific signal requires a Good Scholarship roll. This enables you to eavesdrop on telephone conversations, listen to radio stations in your head, surf the web in your dreams or even watch TV with your eyes closed!
I had intended for there to be upgrades to the power at a cost of -1 Refresh each. There would be things like the ability to inhabit machines the same way BCV can take possession of people and stuff like that. There would have been the ability to construct or jury rig machines that could do just about anything ... ala ... "any sufficiently advanced technology, etc..." Stuff like that.
This isn't really technomancy, but it's what I've got.
Thanks for your time!
