This kit
features a loudspeaker in addition to the various other
components listed below. The speaker provides the audio
experience in addition to the visual effects in the experiments.
About 40
components, and the IC555 Timer, loudspeaker, resistors,
capacitors, LEDs, an LDR (photocell), NPN transistor, diode,
switch, breadboards, connector, bulb, bulb holder, battery
holder, potentiometer, screwdriver, etc.
Instruction manual is well illustrated.
The first 25
experiments are identical to HPKE=01 and HPKE-02. The remaining
20 experiments utilize the IC555 Timer chip, different from
HPKE-01 and HPKE-02.
Exciting
projects include Oscillators and Metronomes of various types,
Electronic Organ assemblies, Electronic Motorbikes, Flashers,
Timing tests, Continuity checker.
Voltage
Drops and ‘short circuits’ are
explored, besides calculations of Effective Resistance
when resistors are connected in series and in parallel.
Works on 4 “C”
Batteries, not included.
