Example text

Figure 2-17 The heating resistor installed Of course, I wanted to take things to the ultimate extreme, and spent days trying to figure out what would give off the most vile and rancid smell possible when the resistor began to shoulder. Plastic wrap was OK, cheese was decent, balloon rubber was even better, but still, I wanted the ultimate. Finally, I had it—hair! Yes, anyone who has played with fire and felt the fickle flames of fate can tell you that burning hair or eyebrows truly smell repulsive.

Figure 2-7 shows the schematic of the beeping thing, and you may recognize some similarities between this schematic and the last one, as they are based on similar parts and principals. In the schematic, the 555 is set up so that its output will turn on the two transistor audio oscillators formed by the pair of NPN transistors. Just like most 555 timer circuits, the timing cycle is controlled by the two resistors on pins 6, 7 and 8, and by the capacitor connected to pins 1 and 2. If you play around with the values of the two resistors, you can control the duty cycle of the timing pulses in order to alter both the off time and on time of the cycle to create more or less beep each time the cycle repeats.

The hinge can be locked into position by placing an object between the hole in the latching part and the hinge body. The spring will then be placed under the hinge to create a pressure that will make the hinge fly open once released. This system is shown in Figure 3-23. Drill a hole through the wooden base for the spring, which is fastened on the underside of the board using a piece of metal with holes drilled at each end. I used one of those 90 degree shelf brackets, and hammered it straight as shown in Figure 3-24.
