LIE DETECTOR

A simple lie detector that can be built in a few minutes, but can be incredibly useful when you want to know if someone is really telling you the truth. It is not as sophisticated as the ones the professionals use, but it works. It works by measuring skin resistance, which goes down when you lie.

TRAFFIC LIGHT

This project operates red, amber and green LEDs in the correct sequence for a single UK traffic light. The time taken for the complete red - red & amber - green - amber sequence can be varied from about 7s to about 2½ minutes by adjusting the 1M preset. Some amber LEDs emit light that is almost red so you may prefer to use a yellow LED. The 555 astable circuit provides clock pulses for the 4017 counter which has ten outputs (Q0 to Q9). Each output becomes high in turn as the clock pulses are received. Appropriate outputs are combined with diodes to supply the amber and green LEDs. The red LED is connected to the ÷10 output which is high for the first 5 counts (Q0-Q4 high), this saves using 5 diodes for red and simplifies the circuit.

LIGHT HOUSE

This project was designed for a model lighthouse to flash a lamp in a simple sequence: two flashes of 2s with a short gap of 1s, followed by a longer gap of 5s before repeating the sequence.

The 555 timer is connected as an astable to provide clock pulses for the 4017 counter. The 4017 has ten outputs (Q0 to Q9) and each one becomes high ('on') in turn as the clock pulses are received. Outputs Q0, Q1, Q3 and Q4 are combined with diodes to produce the flash sequence. A transistor amplifies the current to power the lamp, or LED if you prefer (a 470 LED resistor is included on the stripboard layout). The 1M preset controls the time period (T) of the 555 astable from about 0.1s to 1.5s, for example set T = 1s.

For a different flash sequence connect the diodes to combine different 4017 outputs (Q0-Q9). If the full count from 0 to 9 is not required one of outputs can be connected to the reset input (pin 15). For example connecting Q8 (pin 9) to reset (pin 15) reduces the long gap at the end of the sequence to 3s (with T=1s).

LED HEART PROJECT

This project flashes 18 LEDs at three different rates and you can use these to create an eye-catching Valentine Heart. The circuit is kept simple (and low cost) by using the 4060B IC which is a counter and oscillator (clock) in one package. The circuit requires a 9V supply, such as  battery. It will not work with lower voltages and a higher voltage will destroy the LEDs.

The preset variable resistor can be used to adjust the oscillator frequency and this determines the flash rate of the LEDs. The IC limits the current to and from its outputs so the LEDs can be safely connected without resistors in series to limit the current. The strip board part of the circuit is easy to build but the wiring for the LEDs needs care so detailed instructions are provided below. 

1. resistors: 10k, 470k

MATHEMATICAL MODEL FOR 3 PHASE INVERTER

Analytical model is an important tool for prediction of dynamic performance and stability
limits using different control laws and system parameters. Mathematical model of the inverter mustbe established before the design stage. A schematic diagram of the proposed three-phase UPSinverter system is shown in Fig.1, 

it mainly consists of a controller, switching bridge and an output
filter. The block diagram of the system can be divided into four parts:

1.A Three-phase PWM Inverter

2. Nonlinear Load

3.Multiple-filter

4.Control system

A mathematical modeling of a system for analysis and design of the proposed control system
was described. The mechanism of output waveform distortion of three-phase PWM inverter with
nonlinear loads through detail theoretical analysis was explained. To eliminate the harmonic
components transferred to the load, a multiple-filter was used at the output of UPS. This filter
enables to reduce THD of the output voltage about 5% and voltage regulation 3%.

MAKE OWN MOTOR

You have one drywall screw, one 1.5 V alkaline cell, six inches of plain copper wire, one small neodymium disk magnet, and no other tools or supplies. You have 30 seconds to make an electric motor running in excess of ten thousand RPM. Can you do it? Surprisingly enough, you can. 

Attach the magnet to one end of the battery. The weak, single-point contact that you are making serves as an low-friction bearing. I like to attach it to the button end, but the other end will work as well. (If you do so, the motor will spin the opposite direction. You can also reverse the direction by flipping the magnet up side down.)

Watch out: The screw and magnet can easily fly out of control, and you do not want that screw ending up in your eye. Also note that some of the components, like the wire, can get very warm while you're doing this. Wear safety glasses and use common sense!

eGO ELECTRIC CYCLE

The eGO's a great way to get to work or school. Because you never exert yourself on an eGO, you won't need a shower by the time you get there. And the eGO's cargo rack make it easy to carry a briefcase, laptop, books, whatever. You can take an eGO anywhere you would take a bike, which means in heavy city traffic, an eGO often takes less time than a car.

1.   25 mile range gets most people to work and back without needing to charge.
2.   DOT compliant safety features allow you to safely ride on the streets and with traffic.
3.   Park and secure your eGO just like a bike.
4.   Plenty of cargo room for brief cases -and a whole lot.
