Fabrication Cheap 5 volt DC Sensor Power Supply September 25, 2013 / March 6, 2016 by John Heard One of my recent projects has been to add a Sharp Long Range Infrared Distance Sensor GP2Y0A02YK0F to the data logger to measure front end travel. This sensor is requires 5 vdc power, which should have worked with my RPM Data Logger, but I learned that the sensor required more current than the logger could provide. So we had to add another power supply to run the sensor. Read more » 5vdc Power Supply Data Logger Electrical Sensors
Fabrication Racing Equipment Nitrous Bottle Heater Controller Retrofit August 20, 2013 / July 29, 2019 by John Heard I finally got around to doing something about my home made bottle heater problems last week. I've had issues for years trying to keep a constant temperature for the Nitrous Bottles in my Bottle Heater. The old controller I was using was a mechanical thermostat setup from Johnson Controls, it worked, but it didn't hold a very tight temperature and I was always wondering exactly where I had the temperature set. The dial wasn't really a high accuracy deal. So I pulled the old controller off and switched to a Johnson Controls A419ABG-3C Digital Thermostat and it was a HUGE improvement. The A419 allows you to hold the temp at +/- 1 degree F, far better than the old mechanical control. Read more » Bottle Heater Heater Controls Nitrous Bottle Heater
Nova Destructive Nitrous Flow Testing April 10, 2013 / November 11, 2014 by John Heard When doing some flow testing here recently, we learned a few things we really didn't want to find. We ended up pushing the Highpower Nitrous Pulsoids to their limits recently when doing some flow testing. Technically, they did not reach their limits even though their coils were cooked to this exteme, they still functioned correctly and did not short out.
