Can someone help me with voltage scaling? I've seen some Logic Level Converters from SparkFun but time is matter so I cant wait to get those shipped. I found a topic here: Scaling DC Voltage [0V-6.5V] to [0V to 10V] and this scheme is fine for my project, but since i'm pretty fresh in components, i would like to ask what components would be ideal for this voltage scale. Thanks
EDIT: So my question is, which op-amp should i use to not exceed max output voltage of 5V, and which resistors in combination with that op-amp? My idea is to pick up signal from various sensor in car engine (MAP, MAF, cam positon, fuel system) and scale them down from 5v-0v to 3.3v-0v, process them in Raspberry Pi software i made, and send them processed back to ECU scaled from 3.3v-0v to 5v0v. In global, piggyback ecu with realtime tuning for pre 2000's diesel cars.
