    Led Shift
AI Thread Summary
Creating LED shift indicators for a manual override on an automatic transmission can be achieved without using Arduino. The proposed design involves connecting a circuit in parallel to the shift triggers, allowing LEDs to light up sequentially based on the gear selected. Suggestions include using a frequency-to-voltage converter and a comparator circuit to compare engine speed with driveshaft speed. This method can effectively indicate the current gear by utilizing gear ratios. Overall, there are viable alternatives to Arduino for implementing this LED indicator system.

hello I'm working on a manual shift override on an automatic transmission i have most of my design completed but have no clue where to begin the second half. the idea is to create something to tell me what gear i am in, i wanted to connect a circuit in parallel to the triggers for shifting to where clicking the up-shift trigger moves from one led to the next in the right direction and vise-verse for the downshift trigger, in all it would be 4 leds in total because it is a for gear transmission. could this be done without arduino? any ideas on how to do it?


any help is much appreciated so thank you very much in advanced

depending upon the type of drive (ie front/ rear) you may be able to compare the rotational speeds of the engine versus the rotational speed of the driveshaft (gear ratios). With that, a frequency to voltage converter with a comparator circuit to compare scalar values of the engine speed with the drive shaft might work
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
