Former NASA and Apple engineer. Current SLnumberr and friend of science.

Answers to some common questions:

1) I studied Mechanical Engineering in School. I did my undergrad at BYU and Masters at USC.
2) I worked for NASA JPL for 9 years, 7 of which were working on the Curiosity Rover (I made a video about it you should def totes watch cause it's probably my favorite of all my videos). Then I created Digital Dudz (made some videos about this too) and eventually sold it after 2 years. Then I worked for Apple in their Special Projects Group doing Product Design as a Mechanical Engineer for 5 years. As of 2019, I just make my monthly SLnumber videos.
3) Link to free and therefore substandard build plans for my custom workbench can be found below.
4) I made a 30 Day Creative Engineering Class that teaches my end to end engineering process so you can make stuff too! Check it out here-

  • Choose a random SLnumberr you follow and pick a video that they posted like 9 years ago and comment. It's subtle, but once they get the notification they'll have to assume that you looked at all of their videos in the past 9 years, and think you're a super fan and maybe offer to send you cool stuff.

  • You should look up Dan Ariely. He's a professor of psychology and behavioural economics and in his presentations, he discusses how his team sets up a situation and observe how people behave and particularly about cheating. To some extent, everyone cheats, lies or is deceptive about something but it's more about rationalizing this behaviour. I invested in a private post box as I have had two packages stolen and if I shop online and the website says it doesn't deliver to a private post box, I will keep searching until I find a company that does.
