i would like to say hi first off, im new here and i have a question or even more so i could just use your opion or advice with my attempt at designing a circuit
so im pretty new to electrical circuits and im trying to learn, i learn best by doing opposed to reading text books, and i find looking at circuits that i know what the outcome is, is the most help full, but i have a hard time understanding why things are used where they are in circuits. im starting a huge project for a beginner and the plan is to one day make an ecu, i bought a new 5hp briggs and stratton for this project and i plan to make it run via fuel injection and my own pickup and cdi unit, i want to make all the efi and spark components my self,
i have have a few drawings of what im planning to build, some were copied with slights mods to them by me and the others were conceived ideas i just changed around the parts, as of now i have a injector controller using a lm1949 (very close to the circuit in the data sheet with few mods) i have a us1881 hall sensor circuit i plan on using for the pickup and i have an arduino due (84mhz) for the ecu its self. im not even getting into the programing of this yet, i do know about bit about that part though. for right now i want to build the major circuits then connection them to the motor one at a time and making them work together. the motor starts now its brand new, i want to remove all spark/pickup components and use my own to get it running with no advanced spark first.
so here is the circuit i made with the ideas and design coming from others. i would like some input on it as i dont know very much and im trying to learn. basicily i wonder things like, why are the .001uf caps there and do they go before or after the resistor or diode. does this circuit look usable or am i missing something. oe what changes would you make and why.
im obsessed with building motors and making things, im a machinist and i make everything one can imagine. but this is the first getting into electronics of things even though i use them everyday.
any insight or comments are welcome. and before one asks im not sure where im geting 400v dc from, thats a later project, when i understand a bit more. i have ordered all the parts in all my drawings as well as many more related components. i have no problem ordering more, this is my new hobby i can sink some money into it lol.
thanks
