Programmable DC-CDI test

I was inspired to make and test a programmable cdi on my bench to see how it works realtime. By creating a simulator that will produce both a pulse and the speed of the output, to vary the spark at a certain RPM, we can determine if the cdi under test do have a LIMIT.

(thanks to sir thierry of france with this, he inspired me more to fully understand everything.)

Photo shown is a homemade DC-CDI,  got it from a site, more on that later.

7 segment gear indicator

Having a gear indicator like this one is a very handy visual partner to alert us to what gear we are driving our motorcycle. Some think its un necessary, but sometimes the mind gets blank and forgotten that we are driving at the wrong gear position.

The photo shown with separate gear indicator is very common nowadays with cheap bikes, A designated number on the panel tell us the gear position, (think outside the box here)....

Why not put a seven segment display to show the current gear position.

CIRCUIT

I derived the circuit from this seven segment gear indicator. I had built the unit, but not yet incorporate it inside my panel, it is under on my project plan.



This is the circuit i'll be using on this modification and eliminate the old indicator on my panel, consisting of very cheap and few parts readily available at any electronic part store, The heart of the circuit is based on the mighty 4511 , is a BCD to 7-Segment latch/decoder/driver, that will drive the seven segment display.
