carbonaceous films.Palladium samples tended to achieve thick carbon films (>40um) with relatively low flow ratesand temperatures. The palladium samples grew carbon films most readily at the inlet portion ofthe furnace, especially position #3 (see Figure 1). Flow rates of 15 sccm (1:1) for as little as 1minute have shown uniform and complete surface coverage. Longer deposition times yieldthicker films which after ~30min yield 3D macroscale features. Pd also showed carbon growthat temperatures of 350 oC with 100sccm (1:1) of gas flow. The film characteristics of Pd tend tobe dominated by filaments which assume a woven appearance (See Figure 2 a and b). Thesefilaments range in diameter and wrap around themselves and each other.

Suppose a represents thenumber of full-height vertical units, and b the number of one-third height vertical units. Then theheight of a LEGO assembly (in mm) would be ⎛ b⎞ (1) 9.6⎜ a + ⎟ ⎝ 3⎠since a full vertical unit is 9.6 mm high.If c represents the number of horizontal units, then 8c is the length of a LEGO beam in mm.

The light is controlled by one of the relays. The relay turns the light bulb on and off using a sensor to detect when the chicken house becomes dark. b. Food Supply Unit: The food unit was designed using a plastic bucket whose lower part is shaped like a funnel. The food plate is placed directly under the plastic bucket. At the bottom of the bucket is a gate which is controlled by one of the relays. The gate opens when the relay switch is on and food comes out to the food plate. When the relay switch is off, the gate is closed. The setting
