3-Mode Precision Ignition (eXperimental) Module *NEW*
A multi-mode ignition module for hobby model engines
Kit: $25
Assembled & Tested: N/A
This ignition module was developed to reliably offer multiple modes of operation without the use of a PIC (computer) chip. Running on 6-9 volts, this module is based on the 555 Timer, the world’s most popular IC chip. It supports these modes:
Single shot with auto-timeout (click the links for associated YouTube video)
The coil is energized for just 2-3 ms at a time and in auto-timeout mode:
Eliminates any “dwell” setup requirements
Increases efficiency of the coil which prolongs battery life
Minimizes or eliminates chances of overheating the module or coil.
This is an “experimental” kit version developed on a general purpose circuit board called the “Electro-Cookie”. It is a cleverly designed PCB suitable for IC chips where each half of all the PCB holes are attached together vertically. Components are spaced to take advantage of this alignment, and short wire connections are made to tie columns together. This allows for much easier customizations and improvements should any need to be made in the future.
For use with 6 to 9 volt batteries and coils, negative ground. It even works with an alkaline 9v "smoke alarm" battery when paired with the 6/12v ATV Coil (COIL-UR).
Kit contains:
(1) ISL9V3040P3 IGBT or equivalent
(1) 2N4124 Transistor
(6) Resistors
(1) LED Timing Light
(1) 8-PIN IC Socket
(1) 555 Timer IC
(2) Capacitors
(3) Diodes
(1) Electo-Cookie Printed Circuit Board (PCB) approx 1-1/2" x 2"
(2) Removable Jumpers
(2) 4 Position Screw Terminal Blocks
Approx 12" of 24 Gauge Solid Core Wire
Can be used with "points" or a Hall sensor & magnet setup (sold separately). For points, note this module activates when points are CLOSED. If you need a setup to fire when points OPEN, check into using the TIM6.
For hit & miss engines, order an extra Hall sensor and magnet if you wish to use the "spark saver" option. This feature prevents the ignition from firing while the engine is "coasting", greatly increasing the life of your battery (details included in the instructions).
As always, bench test your entire system before installing on your engine!
