What can cause a house's lights to dim and flash?

I just moved into a new house (in Noe Valley in San Francisco). The house lights flash periodically; about 4 flashes a second for a minute or so. It happens roughly once an hour. The power doesn't go entirely out, all the various electronic gizmos stay on. But the lights dim and brighten.
What can cause that? The house is 1930sish and San Francisco's power infrastructure is not great. It's circuit breakers, not fuses. We just did an extensive remodel and installed a lot of new appliances. As near as we can tell the lights don't flash when any specific appliance is operating, but we could have overlooked something.
