Arduino Stoplight

I made a program with my new Arduino Leonardo board made by Borderless Electronics that simulates the function of a stoplight. This program and circuit goes through the green, yellow, and red lights for 10 seconds, 3 seconds, and 5 seconds, respectively in an infinite loop. This was just a simple program to try out the Arduino language and what I can do with it. I've included a video, some photos, and a screenshot of the code.

1998 Volvo S90 - Water Pump Replacement and Timing Belt Inspection

In addition to replacing my struts this weekend, I also replaced my water pump due to a leak that caused me to top off my coolant once every two weeks or so. In order to replace the water pump, I needed to drain all the coolant and remove the timing belt to access the pump. Since a timing belt in bad condition can greatly impact your engine performance, I inspected that as well to ensure no cracks or broken teeth. Its condition was good, so there was no need to replace it. To replace the water pump, I needed ratchets, wrenches, and screwdrivers. This work was performed off and on over three days totaling approximately seven to eight hours of work.

1998 Volvo S90 - Strut Replacement

This past weekend, I worked on my 1998 Volvo S90 to replace the struts. The struts already had 147,000 miles on them and were squeaking loudly on turns as well as compressing far too much. The project as a whole took one day to complete. I replaced both sides along with new boots and knuckle bolts (where the strut attached to the control arm). I needed regular tools like wrenches, ratchets and a torque wrench as well as a jack, jack stands, and a spring compressor.
