Tibbitts Photo Story: A new electric vehicle!

What exactly goes into building a new electric Go-Kart? Brothers Greg and Dave Bryan complete an electrical circuit to a wheel motor, one of many parts in this Go-Kart build.



Inside the Shiley School Capstone Trailer: Greg, Dave, and their good friend Connor Gilliland pause for a portrait shot.
They have been building this go-kart for three months. Their EV Kart will join the ranks of many electric cars, currently the fastest-growing new car type.


Kart parts first need to be rendered in 3D on a computer before they are built: here, Connor debates with Aracely Mejia over how a kart component should be rendered in SolidWorks, the most popular computer rendering software for engineers.

A first real test: Connor, Greg, and Dave discuss their procedure for applying power to the kart motor, before the circuit is tested.
Connor has his laptop on, reading the voltage signals from the batteries (pictured). When this is finished, the group will know how much power the motor is limited to, an important factor since too much power being sent can blow the motor.
Connor's Alienware laptop, currently busy compiling past temperature readings from the kart motor. Temperature sensors are especially important in electric vehicles, since batteries from even the likes of Tesla are immensely fragile, much more so that gas tanks in a conventional car. This is one drawback of electric vehicles.

Connor reads the latest inputs from the sensors mounted inside the kart motor. These constantly read RPM speeds, which feed into the computer software he is using.
His next action will be to discuss these findings with Greg and Dave. This will help determine the optimal rate at which the electric motor spins, thereby reducing heat and friction with other kart components.

Sunday, Sunday, Sunday, it's Blue Collar Wrestling!

The lovely Miss Lady was one of several emcees for Sunday's Blue Collar Wrestling matches. The event, which happens every Sunday with first bell at 6 p.m., had dozens of audience members, even though it took place during the middle of Super Bowl LIV.  The boot of J.B. Moonshine, one of several wrestlers participating in Sunday's matches. Each wrestler had their own persona, with Mr. Moonshine's schtick being, well, drinking moonshine while he stumbled around the ring in his overalls and boots.  Meet Kris Brady, the self-proclaimed World's Greatest Attraction and a mainstay of Blue Collar Wrestling. Brady fought in the main event, a tag team match between the fan-favorite Brandt Dynasty (Brady's team) and the evil, corporate Rockefeller Foundation. The Foundation won on Sunday.  Mother Russia's Gregor Petrov launches himself into Ugly Joe and prepares for a headbutt. Petrov played the heel to Joe, who was a favorite of the Blue Collar Wrestling...

The Attendee

Despite a considerable decline in church attendance at the University of Portland, individuals like Maria Saenz seek out any opportunity to reflect in this sacred space. With or without fellow worshipers. "Its not about who's with me, all that matters is that God is" But when another student entered the chapel, she jumped at the chance to pray with him. Maria signs her name on her way out, knowing she will be back again. "There is nothing more refreshing in the world, and whenever I get the chance to share that experience with other people it makes it that much better"
