In early 2012, I invented a way to easily mount my phone in my car, via velcro: If you don’t mind using strips of velcro on the dash of your car, you can create a very easy DIY car mount for your phone, right on your dash! After a few phones, I’m still using the … Read more
August 2009 This is an Arduino microcontroller that I wired into my car’s ECU and programmed to calculate the instantaneous/average miles per gallon of my 2002 Honda Civic. The circuit reads pulses from the Vehicle Speed Sensor and Fuel Injector wires. It is wired into my car via a USB cable. It’s pretty accurate once calibrated. My … Read more
June 2008 I used a PIC microcontroller in a circuit to measure my car’s MPH. It measures the frequency of pulses from the Vehicle Speed Sensor, and converts it to miles-per-hour. A summer project involving programming a PIC micro controller to measure my Honda Civic’s MPH. The circuit I made measures the frequency of the pulses coming from … Read more
I was curious about how much gas was actually saved when idling my car with the A/C off, so I gathered some fuel efficiency numbers using the MPGuino I made for my 2002 Honda Civic. The MPGuino can display the instant Gallons Per Hour (GPH) consumed, and this measurement was used for these tests. Testing Notes: All tests were … Read more
