Congratulations to Chris Wlezien, our March 2015 Hacker of the Month who impressed us along with his sensible and considerate Father’s Day current! After his father had not too long ago moved, Wlezien created a singular controllable LED handle bar that made for the proper Father’s Day present.

Wlezien mentioned the inspiration behind his undertaking stemmed from a mechatronics class he took at Rose-Hulman Institute of Know-how, the place he acquired his Bachelor of Science. His professor informed the category a narrative about how he had constructed a easy gentle up handle bar for his home.
“I at all times remembered it and once I lastly had private 3D printer entry I believed it will be enjoyable to take a stab on the undertaking and put my very own spin on it,” Wlezein mentioned.
The undertaking took a couple of weeks whole. It started testing out the code and LED driver to be able to get it working earlier than printing the precise housing and numbers for the bar. Wlezien spent a couple of days engaged on completely different designs to get the appropriate opacity on the numbers and spacing for wiring within the housing after that. After that, it was simply printing, assembling, soldering, and portray. Wlezien describes the operation and reveals his ultimate product in a short video.
2v 20mA LEDs-Fast Resistor Resistor Choice Desk Wlezien used to construct the LEDs into the handle bar.

“The one items of recommendation I can provide is try to contemplate all necessities of the design when choosing parts early. I had to verify the whole lot was climate proof (or sealed within the housing) and that the photo voltaic panel may drive the LEDs and at all times present extra energy than wanted on a median day of daylight” Wlezien mentioned.
So as to scale back the facility wanted to drive it, Wlezien used Pulse Width Modulation (PWM) to regulate the brightness and got here up with a sample to drive the LEDs in such a approach that the obligation cycle for at some point of play throughs was not better than what the photo voltaic cell may provide on a median day.
Wlezien has been 3D printing for years professionally as a mechanical engineer, nonetheless, he solely began printing for exploration and as private interest when his LLC, Nice Scott Know-how, a startup he and his two associates based, bought a Makerbot Replicator 2.
