Miniature High-Rate Speed Control with Brake - Many designs for
high-rate speed controls have been published. Most require two 8-pin
integrated circuits ( ICs) or one 14-pin IC. Many designs suitable for home
construction are fairly large (some as large as 2" square). Many do not
include a brake....(electronic construction project added 09/06)

Miniature Lighthouse Light Simulator - The circuit I came up with is shown
below. It uses two dual low power op amps. The first two devices form a classic
oscillator circuit whose output is a triangle waveform signal. That signal is
routed to a current regulator circuit, which converts the triangle voltage signal to a
triangle current signal through the lighthouse LED. A third op amp generates pulses
timed so they occur at the peak of the triangle waveform. The result is a LED,
which gradually grows brighter, then flashes even brighter before dimming again.
This should produce a light, which simulates a rotating lighthouse light....[Designed

Model Airplane Wing Tip Flasher - The circuit below is designed to flash two
white LEDs mounted at the wing tips of a model airplane. The flasher unit is
powered by a 4.5v supply made of three AA or AAA 1.5v alkaline battery cells.
The average current is about 2ma so a set of batteries should last about 1000 hours of
flashing. The circuit uses one hex Schmitt trigger inverter to perform all the timing
functions. A single n-channel FET drives the two LEDs, each with a peak current of
about 20ma. The circuit flashes the two LEDs in a pattern typical of commercial
airplanes. [Hobby Corner Circuit by Dave Johnson] |

Model rocket launch Controller - Most commercial rocket controllers
available to buy are either expensive or do not have many features. After a lot of

has the ability to control up to 8 pads through a 6 core cable. You may(electronic
