Building New York With Ships' Ballast — Cobblestones

Round stones were used until the introduction of flat oblong granite, known as Belgian block, which was brought in as ship ballast. In the mid-to-late 19th century, cobblestones began to be phased out as a primary material, in favor of less expensive concrete.

How to Get 100KV Out of Your Flyback!!! VERY SIMPLE SETUP

I used a MOT (Microwave Oven Transformer) as a replacement for the flyback and got a 1 cm spark. I used the ballast but it fried my flyback either due to to much voltage on the secondary or too many amps in the primary and I did submerge it in oil but it just wont work anymore so i have to trash the flyback.

Fluorescent Ballasts

Lamp Compatibility Table. Fluorescent lamps use a ballast which transforms line voltage to a voltage to start up and operate the lamp(s). Newer fluorescent ballasts are usually rated for both 120 volts and 277 volts. Some are rated for only 120 volts, others for only 277 volts (used in commercial environments).

The ballast (sometimes called control gear) is a small device wired to the light's circuitry which restricts the amount of electrical current travelling through it. Because your home's mains power has a higher voltage than the light needs to operate, the ballast gives the light a small boost of voltage to start and then just enough of a

Applications of Aggregates in Concrete, Railway Ballast

Uses of Aggregate. In roads and railway ballast the aggregates are used to resist the overall (static as well as dynamic) load, to distribute the load properly to the supporting ground and to drain the water off the surface. In concrete the aggregate is used for economy, reduce shrinkage and cracks and to strengthen the structure.
