Yeah, I've been complaining about the tight time limit to set up the singularity first.
If you join the round a little late as engineer, you're better off to just start on the solars. Their SMES's are connected to the emitter power too, so they'll allow you to power up the singularity.
OR, if you want, you can use the pacman generator. It's just a little trickier than a normal startup. You'll need to get the pacman wired into the SMES output circuit somewhere(Just a tile down from the terminal works). Load up all your solid plasma into it (There's some in the secure storage in a crate). Wire a node into the SMES output circuit, and put the pacman on that node. Wrench it down, then get everything you can set up (Everything but the containment field). Once you're ready to turn on containment, turn on the pacman, and give it a good output value, 20k seemed to work for me. Then go out, turn on containment. Once the containment ring is up, go ahead and fire off the accelerator. When the SMES start charging, you're golden, and can disconnect the pacman.
This worked for me, although I don't understand why the pacman wasn't trying to power the whole damn station. If that was the case, 20k shouldn't have worked. Maybe someone can explain that to me. Do closer devices get priority or something? Or was I actually charging all the APC's in the station, and powering the emitters, with just a 20k output? It ended up being a close call, after the SMES's started charging, I noticed the pacman had run out of fuel. So it was a close one.
