The ESP8266-01?

You can...if you have some decent soldering skills, attach the GPIO16 pin from the SMD chip to the RST pin.
Option 2 is say using a small MCU, like an ATTiny85 to provide a route to ground (via a transistor say) to reset the ESP8266-01. The Attiny85 uses very little power in Watchdog mode and can be used as "waking timer".

I suppose I'll have to ask some of my college ECE techs and see if they can help me solder that on Monday... I don't have any flux, nor the tip or ability to do so right now... Dang. Thanks!

Has anyone done this before? What sized soldering iron tip did you use?

All you need is a normal fine tip solder iron, some practice with soldering and a steady hand. I killed the first board I tried, the second is working fine.

It is easier if you use a very thin wire (more easily bent to the exact right position). Solder to the RST pin first, then to the SMD chip.

and if you really just short gpio16 to rst with a wire you won't get happy at all.
Just use board search on "deep sleep" or at least read this thread:
